  Synthesis and cytotoxic evaluation of novel ester-triazole-linked triterpenoid–AZT conjugates

  摘要：

  Betulinic acid and analogous naturally occurring triterpenoid acids were transformed into the corresponding propargyl esters and subsequently deployed as substrates for a click chemistry-mediated coupling with azidothymidine (AZT) en route to novel 1,2,3-triazole-tethered triterpenoid-AZT conjugates. Twelve new hybrids were thus prepared and assessed in terms of their cytotoxic activity, revealing an interesting anticancer activity of five triterpenoid-AZT hybrids on KB and Hep-G2 tumor cell lines.

  A variety of triterpenoid propargyl amides, prepared from the corresponding acids, was used as substrates for the construction of novel triazole-tethered triterpenoid-AZT conjugates via a click chemistry-mediated coupling with azidothymidine (AZT). Thus, nineteen new hybrids were successfully prepared and evaluated as cytotoxic agents, revealing an interesting anticancer activity of four triterpenoid AZT hybrids on KB and Hep-G2 tumor cell lines.
