Synthesis, antiviral activity and resistance of a novel small molecule HIV-1 entry inhibitor.

ABSTRACT: One of the most critical requirements of the infection of the human immunodeficiency virus type 1 (HIV-1) is the interaction of its surface envelope glycoprotein gp120 with the cellular receptor CD4, which initiates virus entry to cells. Therefore, envelope glycoprotein gp120 has been validated as a potential target to develop HIV-1 entry inhibitors. Here we report the evaluation of a novel non-natural amino acid, termed 882376, reported earlier as a precursor of a CD4-mimetic miniprotein, as HIV-1 entry inhibitor. 882376 showed HIV-1 inhibitory activity against a large panel of primary isolates of different subtype. Moreover, genotyping of 882376 resistant HIV-1 virus revealed three amino acid substitutions in the gp120 including one in the CD4 binding site suggesting that this molecule m
