摘要: Abstract A set of TIBO derivatives endowed with reverse transcriptase (RT) inhibitory activity were analyzed by comparative molecular field analysis (CoMFA). Besides conventional steric and electrostatic fields, lipophilicity potential (MLP) was also used as a third in CoMFA. An informative statistically significant model ( q 2 =0.70, r =0.90, s =0.46) obtained taking into account the three types together. The key determinants governing RT inhibition congeners detected at 3-D level careful CoMFA isocontour maps. To challenge predictive ability model, an external thiazolobenzimidazole (TBZ) examined. Good predictions, suggesting similar binding mode for TBZ derivatives, emerged. Flexible docking experiments on TBZ, other NNIs confirmed common characteristics, found out CoMFA, moreover good correlation between calculated energies potency found.
