Structure Optimization of Aloperine Derivatives as HIV-1 Entry Inhibitors
摘要:
As a step toward developing novel anti-HIV agents, we have identified a class of quinolizidines, including aloperine, which inhibit HIV at 1-5 mu M by blocking viral entry. In this study, we have optimized the structure of aloperine and derived com-pounds with markedly improved activity. Our structural optimization has yielded an aloperine derivative 19 with approximate-ly a 15-fold increase in anti-HIV-1 activity. Our mechanism of action study reveals that compound 19 does not inhibit binding of HIV-1 to receptors, but arrest the virus from fusion with the membrane. Binding of the compound to HIV-1gp120 might be responsible for its anti-HIV-1 entry activity.
