In a continuing study of potent anti-HIV agents, seventeen 28,30-disubstituted betulinic acid (BA, 1) derivatives and seven novel 3,28-disubstituted BA analogues were designed, synthesized, and evaluated for in vitro antiviralactivity. Among them, compound 21 showed an improved solubility and equal anti-HIV potency (EC50 = 0.09 μM) when compared to HIVentryinhibitors 3b (IC9564, (3R,4S)-N′-[N-[
