The development of short-peptide-based inhibitors to prevent HIV-1 entry into the host cell has been rewarded with limited success. Herein, we report a multitarget-directed ligand strategy to generate a series of short-peptide HIV-1 entry inhibitors that integrated the pharmacological activities of a peptide fusion inhibitor able to disrupt HIV-1 gp41 glycoprotein hexameric coiled-coil assembly and a small-molecule CCR5 antagonist that blocks the interaction between HIV-1 and its coreceptor. Among these inhibitors, dual-target 23-residue peptides SP12T and SP12L displayed dramatically increased inhibitory activities against HIV-1 replication as compared to the marketed 36-residue peptide T20. Moreover, results suggested that SP12T and SP12L successfully performed a dual-targeting mechanism. It can be concluded that these short-peptide-based HIV-1 entry inhibitors have potential for further development as candidates for a novel multitarget therapy to treat HIV-1 infection.

D015700 HIV Envelope Protein gp41 Transmembrane envelope protein of the HUMAN IMMUNODEFICIENCY VIRUS which is encoded by the HIV env gene. It has a molecular weight of 41,000 and is glycosylated. The N-terminal part of gp41 is thought to be involved in CELL FUSION with the CD4 ANTIGENS of T4 LYMPHOCYTES, leading to syncytial formation. Gp41 is one of the most common HIV antigens detected by IMMUNOBLOTTING.
