Abstract
ZJU6 was designed to enhance antiangiogenesis and antitumour activity of its parent compound Erianin a clinic antitumour agent This study investigated the detailed biological mechanism of ZJU6 in comparison with that of Erianin Both ZJU6 and Erianin substantially reduced cell viability and induced apoptosis in human cancer cell lines Profound G2/M cell arrest was observed 24 h after treatment of MCF7 cells with ZJU6 ≥ 25 μM or Erianin ≥ 01 μM being consistent with mitotic collapse 05 μM of Erianin or ZJU6 failed to stabilise tubulin PreG1 MCF7 cell accumulating 24 h post treatment indicated apoptosis Caspase3 activity PARP cleavage and Annexin V + ve /PI ve populations correlate the apoptotic destiny of cells exposed to either ZJU6 or Erianin Furthermore ZJU6 showed potent antiangiogenetic property and demonstrated radical scavenging capacity Due to its potent antiproliferative proapoptotic and antiangiogenic activities ZJU6 is an attractive chemotherapeutic agent to be developed
