Abstract: ان الهدف من الدراسة هو تحضير وتشخيص ليكاند ثنائي السن : - [4 - (5,5 - dimethyl - 3 - oxocyclohex - 1 - enylamino) - N - (5 - methylisoxazol - 3 - yl)benzene sulfonamide]من تفاعل السلفاميثوكسازول مع الدايميدون لينتج الليكاند [H2L] باستخدام طريقة الصهر ا | The aim of the study is the preparation and characterization of bidentate Ligand [4 - (5,5 - dimethyl - 3 - oxocyclohex - 1 - enylamino) - N - (5 - methylisoxazol - 3 - yl) benzene sulfonamide]. The ligand was prepared by fusing sulfamethoxazole and dimedone at (170) ?C for half hour. The prepared ligand was characterized by FTIR,UV - Vis spectroscopy, H1,C3 - NMR spectra, mass spectra, molar conductivity measurement and melting point. The molecular structure for the ligand [H2L] which was proposed as drawn in the figure below : - Ligand [H2L]The complexes prepared using reflux in ethanol as solvent were two types namely : - 1 - Complexes of (1 : 1) mole ratio formula [M(H2L)(H2O)2]Cl22 - Complexes of (1 : 1 : 1) mole ratio formula [M(H2L)(HA)] in the presence of KOH as a base, Where : - M(II) = (Co ,Ni ,Cu) HA= 3 - amino phenol. Spectroscopic methods (FT - IR, UV - Vis spectroscopy) along with (A.A), chloride content and melting point were carried out in addition to molar conductance were done for the characterization of all complexes.The proposed tetrahedral geometry around the metal ions studied were concluded from these measurements. [M(H2L)(H2O)2]Cl2 [M(H2L)(HA)]Molar ratio method were used to determine M to L ratio at maximum wave length (?max=455nm ).The ratio were (1 : 1) mole for both complexes (1) and (4). Bentonite clay was used as adsorbent surface to gather with complexes (1) and (4). The adsorption time investigated was between (15 - 120) min at (25)°C as constant concentration for complexes being (70) mg/L for complex (1) and (50) mg/L for Complex (4) and mesh 75))?m. The results revered that the time needed to reach concentration equilibrium in the were 60 to 75 min for complex (1) and (4). during studying isotherm adsorption for the two complexes on bentonite surface, the results revealed that the trend of the adsorption isotherm was (L1) type according to Giles classification , which means that the adsorbent distributed horizontally on the bentonite surface to from a single adsorption layer type langmire.The adsorption phenomenon was studied at different temperatures (10, 25, 37.5, and 50) oC. The results of the adsorption for both complexes on bentonite surface were showed an increase with increasing temperature (endothermic process). Thermodynamic functions (?Ho, ?Go, and ?So) were calculated and the results were discussed. Generally, the increase in the pH of solution was showed an increase in quantity of both complexes that adsorbed on bentonite clay surface at a certain temperature. The study proved that an increase of adsorbent weight may be enhanced the adsorption process of both complexes. Moreover, the particle size of clay surfaces has an influence on the adsorption process showing an increase in adsorption quantity as the particle size decreased.

Abstract: ترتبط بعض الامراض النفسية مثل مرض الاكتئاب الشديد والفصام بتغيرات مناعية حتى ولو كان الشخص سليم من الناحية الجسمية. على الرغم من ان هذين المرضين لايعتبران حاليا من الامراض المناعية الاساسية لكن توجد ادلة تقترح كون الالتهاب يلعب دورا في عملية الاصابة بالاك | Psychiatric illnesses, particularly major depressive disorder (MDD) and schizophrenia, are associated with inflammatory processes even in individuals who are otherwise physically healthy. While it is unlikely that MDD and schizophrenia are a primary inflammatory disorder, evidence suggesting that inflammation plays a subtle role in the pathophysiology of MDD and schizophrenia has been obtained. Several studies have shown that proinflammatory markers have increased in these disorders. However, these studies have included patients with obvious inflammation, i.e., patients with C - reactive protein >6 mg/L. A comprehensive study concluding that these conditions are inflammatory disorders and inflammation is due only to these two disorders have not been performed. In the present study, the inflammatory natures of MDD and schizophrenia were investigated. To achieve this goal, serum levels of the interleukins - 6 (IL - 6) and interleukins - 18 (IL - 18), tumor necrosis factor alpha (TNF?), and soluble interleukin - 2 receptor (sIL - 2R) in MDD and schizophrenia were obtained and compared with those of the control group. The total serum and ionized levels of calcium (Ca) and magnesium (Mg) in the studied groups were then measured.Significant increases (p < 0.05) in the serum levels of IL - 6, IL - 18, TNF?, and sIL - 2R in the MDD and schizophrenic groups were observed in comparison with those of the control group. In general, the schizophrenic group showed higher levels of inflammatory markers than the MDD and control groups. These results indicate a clear inflammatory state in both disorders. The schizophrenic patients exhibited significant changes in the ratios of T. Ca/Mg and I. Ca/Mg in comparison with those of the healthy and MDD patients; this finding reveals that T. Ca/Mg and I. Ca/Mg ratios are better indicators of cation state than serum cation levels alone.Basing on the results of the present study, we concluded that the immunological responses of the MDD and schizophrenia are significantly stimulated. These conditions may be considered inflammatory disorders because of increased pro - and inflammatory factors in both disorders.Anti - inflammatory drugs may be potentially used as an adjuvant aid in treating schizophrenia and MDD. Future studies may involve investigating other proinflammatory markers and following up results of treated patients that utilized and did not utilize anti - inflammatory drugs.

These ligands and their metal complexes were isolated and characterized in solid state using FT - IR, UV - Vis spectroscopy, Nuclear magnetic resonance spectra 1H, 13C - NMR, flame atomic absorption, elemental analysis C.H.N.S. and magnetic susceptibility measurements as well as melting point and conductivity measurements. The nature of bonding between the metal ion and the donor atoms of the ligands was demonstrated through the calculation of Racah parameter and other ligand field parameters, which were calculated using suitable Tanabe - Sugano diagrams. The nature of some (L2) complexes in liquid state was studied by following the molar ratio method which gave results approximately identical compared with those obtained from the isolated in the solid state; also, stability constants of the prepared complexes were studied , they were stable in the molar ratio 1 : 1.According to the results of the above measurements, the following shapes were suggested for the prepared complexes : Complexes of mixed ligands (L1 with L') : All complexes have an Oh geometry except V(IV) complex has a square pyramid geometry. Complexes of ligand (L2) : Complexes of Rh(III), Pd(II) and Au(III) have a square planar geometry, while Pt(IV) complex has an Oh geometry.A theoretical treatment of the ligands and the prepared complexes in gas phase was done using two programs; Hyperchem - 8 and Gaussian program (GaussView Currently Available Versions (5.0.9) along with Gaussian 09 which is the latest in the Gaussian series of programs).Hyper chem. - 8 program used the molecular mechanics and semi - empirical calculation, the heat of formation (?H?f), binding energy (?Eb) dipole moment (µ) for the free ligands and their metal complexes were calculated using ZINDO/1, PM3 and AMBER methods at 298 K. It was found that the complexes were more stable than their ligands; furthermore, the electrostatic potential of free ligands was calculated to investigate the reactive site of the molecules, PM3 was used to evaluate the vibrational spectra of free ligands ,the obtained frequencies agreed well with those values experimentally found; in addition, the calculation helped to assign unambiguously the most diagnostic bands.Electronic spectra measurements for the ligands were calculated theoretically using ZINDO/S method comparing it with the experimental results. It was found that there was a closely relationship between the theory and experimental spectra.Gaussian program semi - empirical (PM3) method which used in order to calculate : the geometry optimization, dipole moment (?),total energy ,electrostatic potential, ELUMO and EHOMO was obtained, evaluate the vibrational spectra of free ligands and these obtained frequencies agreed well with those values experimentally found.Also electronic spectra measurements for the ligands were calculated theoretically by using the job type : Single point energy (SP) along with ZINDO method and also the job type frequency (Freq) used along with CIS method (3 - 21G).

This study explains the importance of the UV light and catalyst as a basic factors in the photocatalytic degradation for both paracetamol and procaine drugs. The study includes the measure of the rate of photocatalytic oxidation by measuring the absorbance of samples of aqueous solution for both drugs which is treated by UV light and ZnO. These absorbance are compared with the initial drug's absorbance. Some parameters which are effected on the rate of photocatalytic oxidation are studied in present research such as the amount of catalyst, initial concentration for the drug's solution, pH and the temperature for the drug's solution. The results show that the photocatalytic oxidation reaction for the paracetamol and procaine obey pseudo - first order according to the Langmuir - Hinshelwood relationship, and also it is found that the photoctalytic oxidation rate fits positively with the increase of the catalyst weight until the weights of ZnO equal to 0.025 g and 0.1 g are considered the optimum weights for paracetamol and procaine respectively where the best photocatalytic degradation is happened. So after these values, the photocatalytic degradation rate is decrease or stablized with the increase of the catalyst weight. In addition, the initial concentration increase for both drugs leads to reduce degradation rate. Also this study is found the increase of pH of reaction solution for both drugs has a positive effect represented by increasing the degradation rate until the pH 8 and 4 are the best acidic function of the paracetamol and procaine respectively. Regarding the change of the temperature has a little effect on the rate of photocatalytic degradation and it was noticed that the reaction rate increases with the increase of temperature. Activation energy is calculated according to the Arrhenius plot of lnK vs. 1/T, the slop of linear plot is equal to ( - Ea/R). Activation energy was found equal to 7.96 KJ. mol - 1 for paracetamol and 8.71 KJ. mol - 1 for procaine. The thermodynamic functions are calculated in current study for each drug and the results for paracetamol are as following : ?G = 63.61 ± 2.85 KJ.mol - 1?H = 5.40 ± 0.13 KJ.mol - 1?S = - 0.189 KJ.K - 1.mol - 1And the results of procaine are as following : ?G = 63.43 ± 2.81 KJ.mol - 1 ?H = 6.15 ± 0.13 KJ.mol - 1?S = - 0.186 KJ.K - 1.mol - 1The results of the suggested mechanism of degradation are shown that the final products for degradation are CO2, H2O and mineral acids.

Abstract: The purpose of this thesis is to report quantum chemical investigations into a series of problems related to contemporary organometallic chemistry. In recent years density functional approaches have become the most commonly used theoretical methodology in organometallic chemistry. Alongside these developments, a number of new tools for analyzing electronic structure such as topological analysis of electron density (Atoms in Molecules theory) have emerged. As a result, theory is now in a position to compute ab initio many of the experimental observables that underpin modern organometallic chemistry.The bonding in the Triosmium carbonyl cluster 1 [Os3(? - H)(? - ?2 - dpa - N,N)(CO)10] and Triosmium carbonyl cluster 2 [Os3( ? - H)2(NHC)(CO)9] are explored using the Quantum Theory of Atoms - in - Molecules (QTAIM). The metal - metal and metal - ligand bond critical points properties ?(r), ?2?(r), H(r), G(r), V(r) and ellipticity, and also the bond delocalization indices ?(A, B), are correlated with the data from previous studies of the organometallic systems. These results have allowed a comparison between topological properties of different atom - atom interactions. In the core of dihydride triosmium cluster 2, Os3H2 part, the topological data recognizes the existence of a bond path in the dihydride bridged Os atoms, Os(1) - Os(3) edges, whereas in monohydride triosmium cluster 1 there is no direct bond path has been found for the interaction between the hydride bridged Os atoms, although a non - negligible delocalization index ?(Os(1)...Os(2)) has been obtained for this non - bonding interaction. A multicenter 4c - 4e interaction is proposed to exist in the core part, Os3H, in cluster 1 and bridged part, Os(1) - H(1) - Os(3) - (H2) in cluster 2. In addition, an interaction of 5c - 5e type is proposed to exist in the core part, Os3H2. All topological parameters calculated for the Os - N and Os - C bonds between the osmium atoms and the pyridyl and NHC ligands in compound 1 and 2, respectively, are similar, and they confirm that these interactions are pure ? bond. The analysis of the topological parameters of the NHC and pyridyl ligands bonds confirm the existence of ? - electron delocalization within the six - membered ring of pyridyl ligand and hindered ? - electron delocalization within the five - membered ring of NHC ligand with some double - bond character in the interaction of the carbine C atom with the adjacent N atoms.

Abstract: تم تحضير مركبات نانو مغناطيسية جديدة باستخدام الكوليستيرول والسلفادايزين مع اوكسيد الحديد المغناطيسي. حضرت هذه المركبات باستعمال طريقة الترسيب المشترك لاوكسيدي الحديد الثنائي والثلاثي ومن ثم ربطه بالحامض بطريقة فوق الاشباع. تم تشخيص المركبات المحضرة بالطر | Two new magnetic nanoparticles (MNPs) were prepared using magnetic iron oxides with cholesterol and sulfadiazine. These compounds were prepared by iron oxide (II and III) co - precipitation, and then the prepared MNP were incubated with cholesterol and sulfadiazine. The synthesized compounds were identified using multiple techniques, including transmission electron microscopy, scanning electron microscopy, diffractive light scattering, and thermogravimetric analysis. Results demonstrated the formation of new magnetic nanoparticles, namely, MNP@Cholesterol and MNP@Sulfadiazine. The interaction between the prepared MNPs and xanthine oxidase (XO) was evaluated as a potential method for the inhibition of the enzymatic activity. The inhibition of XO is an important issue to reduce the formation of uric acid, which is responsible for gout and kidney stone formation. Another potential application is the extraction of the XO enzyme from biological fluids, such as blood, or the immobilization of XO on the surfaces of MNPs as a new application of these insoluble particles.The interaction studies involved the incubation of XO solution with the suspension of prepared MNPs using XO solutions with different concentration and fixed MNP mass. The adsorption studies of XO on MNPs showed that the prepared MNPS can extract suitable amounts of XO from a solution. Slight differences in the XO quantities adsorbed on different MNPs were found. Adsorption isotherms followed the Sips equation, indicating slight heterogeneity in the adsorption active forces on MNPs. Circular dichroism study of the XO adsorption on the prepared MNPs showed significant changes in the secondary structures, namely, reduction of the ? - helix structure. Furthermore, fluorospectrophotometric studies showed changes in the tertiary structure of the XO caused by the interaction with the active sites of the prepared MNPs. The study of the inhibition of XO activity by the prepared MNPs showed mixed inhibition as a result of the changes in the original XO enzyme after interaction with the surfaces. Magnetic Fe3O4 showed the highest inhibition activity, followed by MNP@Sulfadiazine and MNP@Choleterol - XO.

Abstract: تضمن العمل تحضير ليكاندين جديدين من ليكاندات الازو العضويه غير المتجانسه المشتقة من البنزامبدازول الاول هو اليكاند 2'] - 2 - (بنزايميدازوليل) ازو [ - 6,4 - ثنائي كلورو فينول Benzimidazolyl) Azo] - 4,6 - dichloro phenol (BIADClP)) 2 - [2' - والليكاند الثا | This study deals with the preparation of two new ligands from the heterogeneous organic azo ligands drived from Benzimidazol.The first) 2 - [6 - Benzimidazolyl) Azo] - 2,4 - dichloro phenol (BIADClP). The second is 2 - [6 - (benzimidazolylazo)] - 2,4 - dibromo phenol(BIADBrP).The heterogeneous chain in both ligands includes two nitrogen atoms. These two ligands have been identification by the proton nuclear magnetic resonance spectra (1H - NNMR) ,the mass spectrum, infrared, visibale ultraviolet as well as the analysis of the micro - elements (C.H.N).And two new series of the solid canine complexes for these ligands. The first series includes six solid complexes of the ligand (BIADClP) with the metallic ions Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II). The second series includes the preparation of six solid complexes of the ligand (BIADBrP) with the metallic ions mentioned above. The effect of the solvent and the complexes stsbility have been studied on the prepared ligands with the passage of time starting from the moment of the metallic ion solution reaction with the ligand solution and up to 170 minutes. Also, the stability constants for these complexes have been calculated spectrally by visbale - ultraviolet spectra.All results show that these complexes have high stability. The infrared spectra of the prepared complexes have been studied and when compared with the free ligand spedtra give obvious changes as these spectra show new bands not already found in the spectra of both ligands and this is due to the occurance of the correlation between the metallic ions under study with the donar atoms [the nitrogen atom azo group near the heterogeneous chain (N3) and nitrogen atom benzimidazole molecule (N3) , the oxygen atom of hydroxyl group in the heterogenous chain ] in the ligand molecule whereas the other band suffered from obvious changes in shape, intensity and location and this is a proof on the occurance of consistency process between the metallic ions under study and the tow ligands. Atomic absorption spectrometer is used for assigning percentages of the metallic ions in the prepared complexes as well as the analysis of micro - elements (C.H.N). These results indicate the great consistency between the percentages theoretically calculated and practically gained. The magnetic sensitivity indicated that Ni(II) - complex and Cu(II) - complex for both ligands have baramagnatic characteristics whereas the Co(III) - complex, Zn(II) - complex, Cd(II) - complex, Hg(II) complex have adia magnetic characteristics. Also , the study deals with the molar conductivity of the canine complexes dissolved in DMF nad ethanol in a concentration (1×10 - 3) molar and in lap temperature. The results show that the complexes of Ni(II) , Cu(II), Zn(II), Cd(II), Hg(II) do not have ionic characteristics and they are solution of non - electrolytes nature whereas the complexes of Co(III) and for both prepared ligands (BIADClP) and (BIADBrP) have ionic characteristics of the electrolytes nature of type (1 : 1) whereas other remaining complexes do not have any ionic characteristics. Throughout the results that have been reached at, certain structural forms for the canine complexes have been suggested.It has been indicated that the azo Benzimidazol ligands under study behave as tridentate ligands where the consistency happens through the N atom benzimidazole chain (N3) and N azo group far from the heterogeneous chain (N3) oxygen hydroxyl group of the homogeneous chain which leads to forming canine hexagonal complexes having octahydral as steric form.The hybridization of these complexes is d2sp3 concerning Co(III) - complexes of the ligands (BIADClP) and (BIADBrP) whereas the other complexes have the hybridization sp3d2 with the tow prepared ligands under syudy. Moreover, the study deals with the biological activity of these ligands and metallic complexes in the growth of four types of bacterial spores (germs) by using the solvent DMSO and deployment technology as anti - bacterial such as Staphylococcus aureuse and Staph.lentus representative for Gram positive bacteria and enterobacte and Escherichia coli representative for Gram negative bacteria. It is found that ligands and there complexes have different effect as antidepressants in the inhibition and the growth of bacteria under study wheras the ligand (BIADClP) gave the ability in inhibition of the growth of bacteria more than the ligand (BIADBrO) this is due to the change of substituted group on the homogeneous chain and their different in both ligands which led to the emergence of such difference in the inhibition and growth of bacteria.

Abstract: تمثل الستيرويدات فئة هامة من العقاقير الطبيعية وكذلك الصناعية نظرا لقدرتها على اختراق الخلايا واداء بعض الوظائف البيولوجية الاساسية وبشكل رئيسي هي عوامل مضادة للفيروسات ومضادات للاورام. وتقسم الرسالة الحالية على ثلاثة فصول.يمثل الفصل الاول مقدمة عامة حو | Steroids represent an important class of natural as well as synthetic drugs because of their ability to penetrate cells and perform some of the most fundamental biological functions mainly as antitumor and antiviral agents. The present thesis is devided into three chapters.The first chapter represented a general introduction concerning the structures of some potent steroids, and the pathways of the synthetic adrenal steroids as well as their pharmacological importance in medicine, in general. This part is focused mainly also on the pregnenolone as an important potentially active steroid, including its structural modification at the hydroxyl and keto groups at C - 3 and C - 20 and their uses as antitumor agents. Mitsunobu, Suzuki reactions and aldol condensation as well as chalcon formation and their application at steroids have been described. The second chapter is concerned with the experimental work which included different synthetic methodology.The third chapter is the main part of the thesis, described the synthesis of new 3? - pregnenolone ester derivatives at C - 3 via Misunobu reaction of the carboxylic acid derivatives, such as : rhodamin B, indomethacin, naproxen, protocatecuic acid, vanillic acid and p - coumaric acid, which showed inversion in configuration at the ester group at C - 3. In addition, the synthesis of 17 - (4 - chloro - chalconyl)pregnen - 3? - ol has been described, which then treated with various substituted phenylboronic acids such as : 2,4 - difluoro - , 5 - carboxy - 3 - nitrop - ,4 - fluoro, 4 - thiomethyl - , 4 - hydroxy - , 2,4, - dimethoxy - , 4 - trimethylsilyl, 2 - triflouromethyl - , 3 - cyano, 4 - ethoxyphenyl boronic acids under Suzuki cross - coupling reaction conditions using Pd(PPh3)4 as a catalyst and Na2CO3 as a base to give the (E) - 3 - (substituted - [1,1’ - biphenyl] - 4 - yl) - 1 - (3? - hydroxy - pregnen - 17 - yl) - prop - 2 - en - 1 - one. Two compounds, 17 - acetyl - 5 - pregnen - 3? - yl) - 2 - (2,6 - bis(diethylamino) - 9H - xanthen - 9 - yl)benzoate, and 17 - ((E) - 3 - (4 - chlorophenyl)acryloyl) - 5 - pregnen - 3? - yl) - 2 - (2,6 - bis(diethylamino) - 9H - xanthen - 9 - yl)benzoate have been synthesized via coupling reaction using DCC as a coupling reagent to afford these ester with retention in configuration, aiming to study their fluorescence properties. Moreover, tritylation of the pregnenolone has been described to protect the alcohol at C - 3 during the structural modification of keto group at C - 20 under basic medium. The structures of all the synthesized compounds have been assigned from their 1H, 13C, and 2D NMR (HSQC, HMBC, COSY, NOESY) spectroscopy as well the as theoretical calculations of the HOMO and LUMO energies of the trans and cis isomers of the chalconyl pregnenolone aryl derivatives to compare them with the NMR data, which showed that trans isomer is energetically more favoured.Furthermore, the flourescence proroperties of the two rhodainyl pregnenolone esters have been studies which one show remarkable quantum yield (?F) in comparison to Rhodamin B itself.The anti - HIV activity of some arylated chalconyl pregnenolone derivatives have been studies and one of these analogues having diflouro substituents exhibited remarkable activity against HIV - 1 and 2. Therefore, the molecular modeling study of this analogue is performed and showed two hydrophobic interactions and one hydrogen bonding with the amino acids residues of the reverse transcriptase enzyme of HIV.

Abstract: الهدف من هده الدراسة هو تقدير تاثير بعض مشتقات الثياديازول والثيازين الجديدة التحضير على فعالية كل من الانزيمين الكرياتين كاينيز و3 - هيدروكسي - 3 - مثيل كلوتاريل كو - انزيم اي ريدكتيز بالاضافة الى قياس صورة الدهون في مرضى ارتفاع الدهون والفئران المختبرية | The aim of this study is to evaluate the effect of some novel prepared derivatives of thiadiazole and thiazine on the activities of creatine kinase (CK) and 3 - hydroxy - 3 - methylglutaryl CoA reductase(HMGR) in addition to lipid profile in sera of hyperlipidemic patients and in mice induced hyperlipidemia by feeding cholesterol rich diet.The study includes two parts; in vitro study : Sixty individuals with age ranged between (40 - 60) years were enrolled in this study. They were divided into two groups; first group (G1) consists of 30 healthy individuals as a control group with body mass index (BMI) (25.67). The second group (G2)consists of 30 patients with hyperlipidemia and BMI (26.48) which diagnosed by physician. The patients attended the Ibn - Al Naphes hospital during November 2013 to February 2014. Patients with high blood viscosity, diabetes mellitus, renal failure as well as those who are under treatment with statins were excluded. The serum which obtained used in the determination of lipid profile[total cholesterol(Tch),triglyceride(TG), high density lipoprotein(HDL - c), very low density lipoprotein(VLDL - c)], fasting blood glucose(FBG), aspartate transaminase (AST), alanine transaminase(ALT) and C - reactive protein(CRP).Four organic compounds 3 - (4 - (dimethylamino) phenyl) - 2,3 - dihydro - 2 - (3 - nitrophenyl benzo[1,3 - e]thiazin - 4 - one[I], 5 - (4 - imethylamino)benzylideneamino) - 1,3,4 - thiadiazole - 2 - thiol[II], 2 - (4 - dimethylamino)phenyl) - 2,3 - dihydro - 3 - (5 - mercapto - 1,3,4 - thiadiazol - 2 - yl)benzo[1,3 - e]thiazin - 4 - one[III], and N - (4 - (dimethyl amino)benzylidene) - 5 - (isopropylthio) - 1,3,4 - thiadiazole - 2 - amine[IV] were used in this study to test their antihyperlipidaemic ability and their effect on CK and HMGR activities. The results revealed that compounds(III and IV)showed an activation effect in all concentrations on CK and HMGR activities, while compounds(I and II) showed an inhibitory effect in some concentrations for CK and in all concentrations for HMGR. Therefore, compounds (III and IV) were excluded from this study. The results showed that (10 - 4M) for compound I and (10 - 5M) for compounds II give the best inhibition percentage among the other concentrations on CK and HMGR activities which the kinetic study throughout with these concentrations for these compounds. Simvastatin, which considered as standard drug for lipid lowering, was used for comparsion with the potency of compounds I and II on HMGR activity in treatment of hyperlipidaemia. The results showed an inhibitory effect of simvastatin on HMGR activity with percentage inhibition 88%. The effect of compounds (I and II) on ALT and AST were examined in (10 - 4 M) for compound I and (10 - 5M) for compound II in vitro study. The results showed the inhibitory effect of compounds I in concentration (10 - 4 M) and compound II in concentration (10 - 5M) on ALT and AST activities.The Vmax, Km and type of inhibition for compounds I and II on CK and HMGR activities were studied by using Lineweaver - Burk plot. The results showed that also compound I at 10 - 4M was considered to be a noncompetitive inhibitor for CK activity with Vmax values (1000 and 344.82)U/L for uninhibited and inhibited enzyme respectively and Km value (10) mmol/L. The results also showed that compound II at concentration 10 - 5M was considered to be a competitive inhibitor for CK activity with Vmax value (588.23)U/L and Km values (5.51 and 4)mmol/L for the uninhibited and inhibited enzyme respectively.In vitro, the effect of compound (I) with concentration (10 - 4M) and compound (II) with concentration (10 - 5M) were examined in vivo study. The study was carried out with sixty male Wister mice aged seven to eight weeks and theirweight were (180 - 200 g) ,obtained from animal house , in College of Medicine, Baghdad University. The mice were grouped as follow : group one (12 mice) as control group, group(2) : consists of 48 mice in which the mice were daily administered cholesterol (25mg/k/day), in coconut oil 6% and creamy cheese for 28 days. Lipid profile were measured for twelve mice chosen randomly from G2 to diagnosis hyperlipidemia. Then group2 is subdivided into three groups as follows : group (2.A) : (12 mice) as positive control group in which the mice were daily administered simvastatin (40mg /day) as standard drug for hyperlipidemia, group 2B : (12 mice) in which the mice were daily treated with (10 - 4)M of compound (I)via drinking water for 20 days and Group(2.C) : (12 mice) in which the mice were daily treated with (10 - 5)M of compound II for 20 days. The results showed significant elevation in levels of Tch, TG, LDL - c and VLDL - c, while there is significant reduction in HDL - c levels in G2 comparing to control group(G1), after administration of fat rich diet. Simvastatin, compound I with concentration (10 - 4M) and compound II with concentration (10 - 5M) were administrated to G2A, G2B and G2C respectively. Also, the results showed that the activities of CK reduced for group G2B and G2C while it is increased for G2A. The results also showed that the activities of HMGR were reduced in the three treated groups. The results revealed that compounds I and II exhibit more potent antihyperlipidaemic effect than simvastatin. Also, compound I showed more potent antihyperlipidaemic effect than compound II.The results revealed that compounds I and II showed a noncompetitive inhibitor effect on CK with Vmax values(1000and 166.6) U/L for uninhibited and inhibited enzyme respectively and Km value (0.6) mmol/L for compound I, and with Vmax vales (1000 and 250)U/L for uninhibited and inhibited enzyme respectively and Km value (0.84) mmol/L for compound II.In conclusion, the novel synthetic compounds (I and II) seem to be of interest in the development of new antihyperlipidaemic agents that exhibit inhibition effect on CK while statins cause increase in this enzyme. Also these compounds exhibit inhibition effect on HMGR activity more than simvastatin, which is a key enzyme in cholesterol synthesis.
