Novel Betulinic Acid–Nucleoside Hybrids with Potent Anti-HIV Activity
摘要:
Novel betulinic/betulonic acid-nucleoside hybrids were synthesized as possible new anti-HIV agents. Among the synthesized hybrids, two compounds were highly effective against HIV. Compared with AZT and DSB, compounds 10a (IC50 = 0.0078 mu M, CC50 = 9.6 mu M) and 10b (IC50 = 0.020 mu M, CC50 = 23.8 mu M) showed more potent or equipotent, respectively, antiHIV activity but displayed lower cytotoxicity.
