HIV-1 integrase strand-transfer inhibitors: Design, synthesis and molecular modeling investigation
摘要:
This study is focused on a new series of benzylindole derivatives with various substituents at the benzene-fused ring, suggested by our 3D pharmacophore model developed for HIV-1 integrase inhibitors (INIs). All synthesized compounds proved to be active in the nanomolar range (6-35 nM) on the strand-transfer step (ST). In particular, derivative 4-[1-(4-fluorobenzyl)-5,7-dimethoxy-1H-indol-3-yl]-2-hydroxy-4-oxobut-2-enoic acid (8e), presenting the highest best-fit value on pharmacophore model, showed a potency comparable to that of clinical INSTIs GS 9137 (1) and MK-0518 (2). The binding mode of our molecules has been investigated using the recently published crystal structure of the complex of full-length integrase from the prototype foamy virus in complex with its cognate DNA (PFV-IN/DNA). The results highlighted the ability of derivative Se to assume the same binding mode of MK-0518 and GS 9137. (C) 2010 Elsevier Masson SAS. All rights reserved.

Present study is focused on design, synthesis, and biological evaluation of substituted benzylindole derivatives as anti-HIV, anti-fungal, and anti-bacterialagents. Out of the reported compounds, compound B1 and B2 showed potent Anti-HIV activity, whereas compound B1–B4 showed good anti-fungal and anti-bacterialactivity. ADME properties of benzylindol analogs were analyzed using Qikprop 2.5 tool
