  Anti-AIDS Agents 90. Novel C-28 Modified Bevirimat Analogues as Potent HIV Maturation Inhibitors

  摘要：

  In a continuing study of bevirimat (2), the anti-HIV-maturation clinical trials agent, 28 new betulinic acid (BA, 1) derivatives were designed and synthesized. Among these compounds, 17, with a C-28 MEM ester moiety, and 22, with a C-28 ethyl hexanoate, increased the anti-HIV replication activity compared with 2 by 2-fold while compounds 40, 41, 48, and 49, with C-28 piperazine or piperidine amide substitutions, increased the activity by 3- to 15-fold. The best new compound, 41, exhibited an anti-HIV IC50 of 0.0059 mu M compared with 0.087 mu M antimaturation effects, as confirmed by TZM-bl assay, in blocking the HIV replication. The results suggest that proper C-28 substitutions can further enhance the antimaturation activity of 2 without any antientry effects. Thus, 41 may serve as a promising new lead for development of anti-AIDS clinical trial candidates.
