Studies on methyl xestopongoate analogues:design, synthesis and antitumor activities

    Graphical Abstract
    • Abstract
  • Fifty-two methyl xestospongoate analogues were designed, synthesized and evaluated for the antiproliferative activity. Starting from alkynyl methyl ester and diyne, methyl xestospongoate analogues 4 ( a - m )- 7( a - m )were synthesized by Cadiot-Chodkiewitz coupling and Sonogashira coupling reactions. Their structures were identified by 1H NMR, 13C NMR and HREI-MS. The cytotoxic inhibiton activities in vitro of some compounds were evaluated against human cancer cells A549 and P-388 by a CCK-8 method. Among them, compound 6k exhibited potent cell growth inhibitory activity against A549 and P-388 cancer cells, with IC50 values of 9. 36 and 9. 62 μmol/L, respectively.
