Abstract:
يتضمن البحث تحضير مشتقات جديدة للقاعدة النتروجينية البيورينية (ثيوفلين) باضافة مجموعة ازو (Azo group) الى هذه القاعدة حيث تتصل بالطرف الاخر لمجموعة الازو الحلقية حلقة بنزين معوضة بمجاميع مختلفة مثل (SO3H , Br , NO2) وقد حضرت اربعة مشتقات للثيوفيلين1 - SA | This study include synthesis of new derivatives of nitrogen bases purin (theophylline) by adding azo group to these Bases where connecting in the other terminal with Banzen ring substituted by different group like (NO3, Br,...) Four derivatives of the theophylline where these are SAT , BAT , 4NAT , 3NAT these derivatives were used as ligand because of is abitity to from helating complex , these derivatives were reacted with eight metal ions these are (Fe2+, Co2+, Ni2+, Cu2+, Zn2+, La3+, Ce3+) these complex were characterized by many methods as molarratio, measuring of electrical conductivity electronic spectra , which helped us to find the chemical structure of those complex this study also found that ratio of ligand metal was 2 : 1 this study also include the study of biological effect for these ligand and complexes on four deferent pathogenic species (staphylococcus aureus, streptococcus viridans ) ,(protens vulgaris, pseudomonas aeruginosa ) the two first species are gram positive while the other are gram negative , finally (by using disk diffusion method) it was found that these compounds show different activity of inhibition on other growth of the Becteria.
