Research Abstract |
APOBEC3G is a human antiviral protein that blocks HIV-1 replication. However, the antiviral activity of A3G is overcome by the HIV-1 protein Vif that degrades APOBEC3G. We designed and synthesized artificial compounds MF1, MF2, and MF3 to examine the Vif-inhibitory activity. We found that MF2 and MF1(generated by adding DTT to MF2) increase the expression of APOBEC3G to a level much higher than that observed in the absence of Vif, without affecting the level of Vif expression. Furthermore, MF2, MF3, and MF1(generated by adding DTT to MF2 or MF3) significantly inhibited the MAGI cell infectivity of wild-type HIV-1. These findings may contribute to the development of a novel anti-HIV-1 drug.
