Abstract: In this study, the preparation of a number of new drugs from the derivatives of ascorbic acid (vitamin C) and ribose have been done through the formation of esters of these compounds. The tetra - acid esters of ribose have been obtained with mefenamic acid and methyldopa and aspirin during treatment of mefenamic acid, methyldopa and aspirin chlorides with ribose. The tetra - ester of ascorbic acid with ampicillin has also been obtained through the reaction of ampicillin chloride with ascorbic acid. The Products have been diagnosed by infrared spectroscopy (IR).The effect of four products has been studied on lipase activity compared with metronidazole benzoate as ester on lipase activity. The results showed that the highest activity of the enzyme was when tetra aspirin ester of ribose was used (2.36 Cherry - Crandall’s unit) and the lowest activity (1.37 Cherry - Crandall’s unit) when using tetra ampicillin ascorbic acid ester. Other compounds showed a slight increase in lipase activity.The effect of four compounds have been studied on cholinesterase activity, the results showed that tetra ampicillin ester is the highest effect to increase cholinesterase activity

The equilibrium Constants for complexes formation were found to follow (3<4<9<6<7<8<5<1<2) arrangement. The energy of the complexes and extiztion coefficient were found to have the same arrangement shown above. The difference in the values of this physical properties are attributed to structural difference of the molecular (donating and withdrawing substituted groups). KCT values for the complexes were calculated from Bensi - Hildebrand equation and was found to fit the following arrangement ( 9<8<7<4<3<6<5<1<2 ), depending mainly on the types of substituted groups on aniline ring. Part Two Effect of temperature variation on equilibrium constant for the charge - transfer complexes formation were measured by applying Bensi - Hildebrand equation ,which used to estimate the thermodynamic parameter such as (?G0, ?S0 , ?H ) in absolute ethanol. Part Three The kinetic of the formation of charge - transfer complexes in absolute ethanol was studied.The results indicated that, the more stable charge - transfer complexes have higher rate constant formation and the kinetic of CTC was first order. Part Four Photo stability of (1 - 9) Schiff bases against direct sun light was investigated as solution in both ethanol and dimethyl sulfoxide DMSO.The results indicated that, the rates of photo decay of the Schiff bases in ethanol were faster than in DMSO solvent and the photo decay kinetic was found to follow first order reaction in ethanol and second order in DMSO solution.

The modification process started from the conversion of carboxyl group which is existing in these drugs (except in Isoniazid) into esters, chlorides and acid hydrazide.The drugs have been linked to each other and to itself via amide linkage through the reaction of their acid chlorides and acid hydrazides to afford 1,2 - diacyl hydrazine derivatives(M17 - M27). Some acid hydrazides have been treated with isophthaloyl chloride to Benzene - 1,3 - dicarbo hydrazide - 1,3 - Bis substituent(M28 - M30). The same hydrazides have been treated with Benzen - 1,3,5 - tri carbonyl tri chloride to afford Benzen - 1,3,5 - tricarbhydrazide - 1,3 - Tris substituent (M31 - M33).

Another modification onto drugs has been done through the linking of these drugs with quinazoline nucleus through amide linkage to afford N - (4 - oxo - 2 - phenylquinazolin - 3(4H) - yl)amide - substit derivatives (M38 - M42). Another modification has been carried out through the reaction of hydrazides with Aromatic aldehydes to afford the mono hydrazide - hydrazones derivatives or Schiff's bases (M43 - M65) and di hydrazide - hydrazones derivatives in which two moles from hydrazide have been treated with one mole of dialdehyde(M66 - M73). In addition, new hydrazones have been synthesized through the reaction of hydrazides with Isatin nucleus which is well known as biological active center to afford the compounds (M74 - M77) with good biological activity. Benzodiazepines have been obtained through the reaction of Isoniazid hydrazones with glycene phthalimide and p - aminobenzoic acid(M82 - M92).

The Derivatives of 5 - substit - 2 - Mercapto - 1,3,4 - Oxadiazole(M98 - M103) have been obtained through the reaction of the drug hydrazides with CS2 in the presence of KOH. The oxadizoles have been treated with hydrazine hydrate to afford 4 - amino - 5 - sub - 4H - 1,2,4 - triazole - 3 - thiol derivatives for the Non - steroidal anti - inflammatory drugs(M104 - M107). In addition, 5 - sub - 1,3,4 - Oxadiazole - 2 - amine derivatives have been obtained through the reaction of drug hydrazides with BrCN(M108 - M111). The compound 5 - {1 - [4 - (2 - methylpropyl)phenyl]ethyl} - N3 - phenyl - 4H - 1,2,4 - triazole - 3,4 - diamine (M113) has been synthesized through the reaction of the compound 2 - {2 - [4 - (2 - methylpropyl)phenyl]propanoyl} - N - phenylhydrazinecarbothioamide (M112) with hydrazine hydrate. The ester compound 2 - hydroxyphenyl 2 - [4 - (2 - methylpropyl)phenyl]propanoate (M114) have been obtained through the reaction of Ibuprofen chloride with salicylic acid. The two compounds, 2 - (4 - Isobutyl - phenyl) - propionic acid [1 - (4 - methyl - piperazin - 1 - ylmethyl) - 2 - oxo - 1,2 - dihydro - indol - 3 - ylidene] - hydrazide (M115) and 2 - (4 - Isobutyl - phenyl) - propionic acid [5 - fluoro - 1 - (4 - methyl - piperazin - 1 - ylmethyl) - 2 - oxo - 1,2 - dihydro - indol - 3 - ylidene] - hydrazide (M116) have been obtained through the reaction of M74, M77 with excess of formaldehyde and equimolar of N - methyl piperazine.The synthesized compounds have been identified using Infra - red spectroscopy FTIR, Nuclear Magnetic resonance (1H,13C), Mass spectroscopy and X - Ray.
