生物活性:
OTSSP167 (OTS167) is a highly potent and ATP-competitive MELK inhibitor with IC50 value of 0.41 nM.

体内研究:
OTSSP167 (20 mg/kg, i.v.) results in tumor growth inhibition (TGI) of 73% in xenograft mouse model; OTSSP167 (1, 5, and 10 mg/kg, p.o.) reveals TGI of 51, 91, and 108%, respectively. OTSSP167 (20 mg/kg, p.o.) shows no tumor growth suppressive effect on PC-14 xenografts.

体外研究:
OTSSP167 inhibits the growth of A549 (lung), T47D (breast), DU4475 (breast), 22Rv1 (prostate) and HT1197 (bladder) cancer cells with IC50 values of 6.7, 4.3, 2.3, 6.0 and 97 nM, respectively. OTSSP167 can abrogate the mitotic checkpoint, disrupt MCC and MCC-APC/C interaction in MCF7 cells. OTSSP167 causes GFP-MELK localization to cell cortex in prometaphase cells. OTSSP167 is a MELK selective inhibitor, exhibits a strong in vitro activity, conferring an IC50 of 0.41 nM.
