  Anti-AIDS agents 88. Anti-HIV conjugates of betulin and betulinic acid with AZT prepared via click chemistry

  摘要：

  In the present study, a new strategy to link AZT with betulin/betulinic acid (BA) by click chemistry was designed and achieved. This conjugation via a triazole linkage offers a new direction for the modification of anti-HIV triterpenes. Click chemistry provides an easy and productive way for linking two molecules, even when one of them is a large natural product. Among the newly synthesized conjugates, compounds 15 and 16 showed potent anti-HIV activity with EC50 values of 0.067 and 0.10 mu M, respectively, which are comparable to that of AZT (EC50: 0.10 mu M) in the same assay.
