Discovery of 5,6-Dihydro-indolo[1,2-a]quinoxaline Derivatives as New HIV-1 Inhibitors In Vitro
In continuation of our program to find compounds with potent anti-human immunodeficiency virus type 1 (HIV-1) activities, seventeen 5,6-dihydro-indolo[1,2-a]quinoxaline derivatives (1-17) were preliminarily evaluated as HIV-1 inhibitors in vitro. Among all the derivatives, especially compounds 10 and 17 showed the most potent anti-HIV-1 activities with EC50 values of 2.42 and 3.39 μg/mL, and TI values of 63.76 and 53.60, respectively.
