Sd. Young et al., 2-HETEROCYCLIC INDOLE-3-SULFONES AS INHIBITORS OF HIV-1 REVERSE-TRANSCRIPTASE, Bioorganic & medicinal chemistry letters, 5(5), 1995, pp. 491-496
A variety of 2-heterocycle substituted 3-phenysulfonyl-5-chloroindoles
were investigated as replacements for the 7-carboxamide functionality
of the potent HIV-L reverse transcriptase inhibitor L-737,126 The 2-c
arboxamide series of compounds typified by L-737,126 have poor solubil
ity. Replacement of the carboxamide moiety with a variety of heterocyc
les results in a series of potent enzyme inhibitors with equivalent ex
vivo antiviral activity and improved physicochemical properties.
