  3-O-Glutaryl-dihydrobetulin and related monoacyl derivatives as potent anti-HIV agents

  摘要：

  3-O-Acyl-betulin and -dihydrobetulin derivatives were prepared and evaluated for anti-HIV activity. 3-O-Glutaryl-dihydrobetulin (17) demonstrated extremely potent anti-HIV activity with an EC50 value of 2 x 10(-5) muM and a TI value of 1.12 x 10(6). 3-O-(3',3'-Dimethylsuccinyl)- and 3-O-(3',3'-dimethylglutaryl)-dihydrobetulins (15, 16) were also potent anti-HIV compounds with EC50 values of 0.0017 and 0.0013 muM, respectively, and TI values of 16,160 and 19,530, respectively.

  Fourteen novel conjugates of 3,28-di-O-acylbetulins with AZT were prepared as anti-HIV agents, based on our previously reported potent anti-HIV triterpene leads, including 3-O-acyl and 3,28-di-O-acylbetulins. Nine of the conjugates (49-53, 55, 56, 59, and 60) exhibited potent anti-HIV activity at the submicromolar level, with EC(50) values ranging from 0.040 to 0.098 mu M in HIV-1(NL4-3) infected MT-4 cells. These compounds were equipotent or more potent than 3-O-(3',3'-dimethylsuccinyl) betulinic acid (2), which is currently in Phase IIb anti-AIDS clinical trial. (C) 2010 Elsevier Ltd.
