    Project supported by the National Basic Research Program of China (No. 2010CB833804), the National Natural Science Foundation of China (Nos. 41376148, 21172204, 30572246), and the National High-Tech R&D Program of China (Nos. 2013AA092901, 2012AA092104, 2007AA091502).

Twelve new halogenated derivatives of PKC-412 were synthesized from the marine microbial natural product, staurosporine. Their structures were identified by 1H NMR, 13C NMR, IR and HRESIMS. The cytotoxicities of these halogenated derivatives against HL-60, A549 and hela cell lines were evaluated using thiazolyl blue tetrazolium bromide (MTT) method. The results showed that compounds 4 and 10 displayed comparative cytotoxicity of PKC-412 against HL-60 and A549 cell lines with IC50 values of 0.5~0.95 μmol·L-1, and the halogenation on phenyl nucleus of benzamide moiety increased the selectivity of compounds to A549 cell, indicating a worth of further study.

Key words: staurosporine, PKC-412, halo-derivatives, cytotoxicity
