  描述：

  4-(piperazin-1-yl)butanoic acid methyl ester 在 4-二甲氨基吡啶 、 对甲苯磺酸 、 三乙胺 、 sodium hydroxide 作用下， 以 四氢呋喃 、 甲醇 、 二氯甲烷 为溶剂， 反应 2.0h， 生成 4-[[(1R,3aS,5aR,5bR,7aR,9S,11aR,11bR,13aR,13bR)-3a-[4-(3-carboxypropyl)piperazine-1-carbonyl]-5a,5b,8,8,11a-pentamethyl-1-prop-1-en-2-yl-1,2,3,4,5,6,7,7a,9,10,11,11b,12,13,13a,13b-hexadecahydrocyclopenta[a]chrysen-9-yl]oxy]-2,2-dimethyl-4-oxobutanoic acid

  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.
