| Outline of Final Research Achievements |
Based on our finding of a first-in-class drug candidate as a viral maturation inhibitor, bevirimat [3-O-(3',3'-dimethylsuccinyl)-betulinic acid], and potent anti-HIV active 3-O-acyl-(dihidro)betulin derivatives (e.g. 3-O-glutarydihydrobetulin and 3,28-di-O-dimethylsuccinylbetulin), a series of conjugates of 3,28-di-O-acylbetulin derivatives and HIV-reverse transcriptase inhibitor, AZT, with a linker moiety containing glycine, were prepared and evaluated their anti-HIV activity. Several derivatives showed more potent anti-HIV activity than bevirimat. In addition, preliminary study for preparing conjugate of betulinic acid derivative and AZT, where 5'-position of AZT is not involved, resulted in the finding of quite potential anti-HIV agents. Further study is in progress.
