Compound class:
Synthetic organic
Comment: Fostemsavir is a phosphonooxymethyl prodrug of temsavir (BMS-626529) [4-5]. It is classified as an attachment inhibitor [2]. Temsavir binds to HIV envelope glycoprotein 120 (gp120) and thereby blocks viral attachment to the host CD4 molecule on T-lymphocytes. Naturally ocurring HIV-1 gp120 polymorphisms that could impart resistance to fostemsavir are uncommon [1].
