The kinesin spindle protein (KSP/Eg5) is a potential target in cancer therapy.It, which has attracted great interest in discovery of compounds that inhibit KSP. Here, a series of 4-oxo-tetrahydro-β-carline derivatives 9a~94f have been designed and synthesized as a novel class of KSP inhibitor. The synthesized compounds were, and evaluated for their inhibition of aganist KSP. All compounds inhibited ATPase activity with IC50 below that of the analog Monastrol. 9c has an IC50=0.065 μmol•L-1 for inhibition of KSP, >100-fold more active than Monastrol. The research results provide new candidate molecules for study of anticancer drugs.

Key words: kinesin spindle protein, 4-oxo-tetrahydro-β-carline, anticancer
