Synthesis and biological evaluation of imidazole thioacetanilides as novel non-nucleoside HIV-1 reverse transcriptase inhibitors
摘要:
A series of 2-(1-aryl-1H-imidazol-2-ylthio)acetamide [imidazole thioacetanilide (ITA)] derivatives were synthesized and evaluated as potent inhibitors of human immunodeficiency virus type-1 (HIV-1). Among them, the most potent HIV-1 inhibitors were 4a5 (EC50 = 0.18 mu M), and 4a2 (EC50 = 0.20 mu M), which were more effective than the lead compound L1 (EC50 = 2.053 mu M) and the reference drugs nevirapine and delavirdine. The preliminary structure-activity relationship (SAR) of the newly synthesized congeners is discussed. Crown Copyright (C) 2009 Published by Elsevier Ltd. All rights reserved.

double nucleophilic substitution reaction of N-tosylaziridinofullerene with thioureas or guanidines affords the fullerothiazolidin-2-imine or fulleroimidazolidin-2-imine derivatives, respectively. In the case of unsymmetrical thioureas connecting an alkyl and an aryl group on each of the nitrogen atom, the transformation exhibits excellent chemoselectivity with only the aryl substituted nitrogen atom bonding
