ACAi-028

ACAi-028 is a small molecule inhibiting HIV-1 replication (EC50=0.55 uM) that targets a hydrophobic pocket in the N-terminal domain of capsid (CA-NTD).ACAi-028 binds directly and noncovalently to HIV-1 capsid monomer.ACAi-028 inhibits the early stage of the HIV-1 life cycle and does not affect the late stage, also prevents multiple-round HIV-1 infection using HIV-1 strains (HIV-1NL4-3 and HIV-1LAI), except for HIV-2 strain (HIV-2ROD).ACAi-028 inhibits the replication of various types of HIV-1 strains (HIV-1104pre and HIV-1MDR/B) in PBMCs and HIV-1ATVR5μM in MT-4 cells, with negligible cytotoxicity.
