Abstract:
Inhibitors of kinesin spindle protein (KSP) are a promising class of anticancer agents that cause mitotic arrest and induce apoptosis of tumor cells. A series of novel tetrahydro-beta-carboline derivatives were synthesized as kinesin spindle protein inhibitor and evaluated as potential antitumor agents. All compounds showed promising KSP inhibitiory activity. Compounds 8 and 9 exhibited better antitumor activity (Lung/A549, Stomach/AGS) than CK0106023 with GI50/IC50 values (1.07/1.62 and 1.46/3.27 micromol x L(-1), 1.09/>10 and 1.22/6.33 micromol x L(-1), respectively).
