Discovery of tricyclic HIV-1 integrase-LEDGF/p75 allosteric inhibitors by intramolecular direct arylation reaction.

PubMed Abstract: We have been conducting exploratory research to develop human immunodeficiency virus type-1 (HIV-1) integrase-LEDGF/p75 allosteric inhibitors (INLAIs). Here, we report on a newly designed compound with a tricyclic scaffold that shows promise as an inhibitor. Various scaffolds were synthesized by intramolecular direct arylation reaction to fix the position of a lipophilic side chain required for antiviral activity. Among these, the compound having an N-mesyl dihydrophenanthridine ring showed the best antiviral activity. Compound 42i, prepared by side chain optimization of the C-4 and C-6 positions, exhibited high antiviral activity against wild-type (WT) and the T174I mutant (EC (WT) = 4.6 nM, EC (T174I) = 83 nM) with a good PK profile. Based on co-crystal structural analysis of compound 42i and WT HIV-1 IN CCD, we discuss the interaction important for high antiviral activity.
