Compound 1 (VEC-5) was identified as a potent small-molecular HIV-1 viron infectivity factor inhibitor that targets the viron infectivity factor-ElonginC interaction. A structure-activity relationship study was carried out to develop compounds with improved efficacy against HIV-1 and 49 indolizine derivatives of three categories were designed and synthesized. We found that five compounds exhibited promising anti-HIV-1 activity, and the most active compound 2g had an IC50 value of 11.0 ìm. These results provide new information to develop highly potent small-molecule HIV-1 viron infectivity factor inhibitors.
