Novel HIV-1 capsid-targeting small molecules of the PF74 binding site.

ABSTRACT: The PF74 binding site in HIV-1 capsid protein (CA) is a compelling antiviral drug target. Although PF74 confers mechanistically distinct antiviral phenotypes by competing against host factors for CA binding, it suffers from prohibitively low metabolic stability. Therefore, there has been increasing interest in designing novel sub-chemotypes of PF74 with similar binding mode and improved metabolic stability. We report herein our efforts to explore the inter-domain interacting indole moiety for designing novel CA-targeting small molecules. Our design includes simple substitution on the indole ring, and more importantly, novel sub-chemotypes with the indole moiety replaced with a few less electron-rich rings. All 56 novel analogs were synthesized and evaluated for antiviral activity, cytotoxi
