The development of peptide-based HIV entry inhibitors has made an important contribution to the stock of anti-HIV drugs. In particular, the peptide-based anti-HIV drugs enfuvirtide and albuvirtide were approved for clinical use by the U.S. FDA and CFDA in 2003 and 2018, respectively. Peptide-based HIV entry inhibitors exert antiviral activity by targeting the early stage of viral infection, i.e., binding of a viral surface protein to the receptor(s) on the host cell and the subsequent fusion between the viral and host cell membranes. Therefore, they are particularly useful for HIV-infected patients who have failed to respond to the highly active antiretroviral drugs (ARD) targeting the late stage of HIV replication, such as reverse transcriptase inhibitors and protease inhibitors. In this chapter, we will focus on the past, current, and future trends in research and development of peptide-based HIV entry inhibitors.
