Combination antiretroviral therapy (cART) has transformed HIV-1 infection, once a fatal illness, into a manageable chronic condition. Drug resistance, severe side effects and treatment noncompliance bring challenges to the cART implementation in clinical settings and indicate the need for additional molecular targets. Here we have identified several small-molecule fusion inhibitors, guided by a neutralizing antibody, against an extensively studied vaccine target- the membrane proximal external region (MPER) of HIV-1 envelope (Env) spike. These compounds specifically inhibit the Env-mediated membrane fusion by blocking CD4-induced conformational changes. An NMR structure of one compound complexed with a trimeric MPER construct reveals that the compound partially inserts into a hydrophobic pocket formed exclusively by the MPER residues, thereby stabilizing its prefusion conformation. These results suggest that the MPER is a potential therapeutic target for developing fusion inhibitors and that strategies employing an antibody-guided search for novel therapeutics may be applied to other human diseases.
