To provide deep insight into the correlation between inhibitory activities and structures of xanthones, linear regression method was employed to establish QSAR models for 16 xanthone derivatives that have diverse structures. The accuracy and predictive power of the proposed QSAR model were verified by semi empiric PM3 method, optimation, and va lidation. The result showed that the best model was model 3. ORG-P7 SYNTHESIS AND ANTI-INFLAMMATORY EVALUATION OF SOME MORE NEW 1,2,4-TRIAZOLO[3,4b]THIADIAZOLES AS AN ANTIMICROBIAL AGENTS- PART I F.M.Aqlan, R.M.Abdel-Rahman and K.O.Al-Footy Department of Chemistry, Faculty of Science , King Abdel-Aziz University, P.O.Box 80203, Jeddah, 21589, Kingdom of Saudia Arabia Some new 1,2,4-triazolo[3,4-b][1,3,4]thiadiazoles (2-9) have been synthesized from the interaction between 4-amino-3-(pyrid-4-yl)-5-mercapto -1,2,4-triazole (1) and α,β-bifunctional compounds such as triethylphosphite, trifluroacetamide, cyanamide, isothiocyanate, carbon disulfide and or fluorinated benzaldehyde in different conditions and medium. Structures of the products have been established from their elemental and spectral data. All the targets obtained were evaluated as anti -inflammatory agents in compared with the standard drug Indomethacin as well as antimicrobial agents.
