SERP Comments:

Recently reported selectivity data show that this is not a selective MELK inhibitor (http://www.kinase-screen.mrc.ac.uk/screening-compounds/594372). Based on the selectivity data, I do not recommend this compound as a probe to use in cells or model organisms even though this molecule has entered into Phase 1 clinical trials. OTSSP167 abrogates mitotic checkpoint through inhibiting multiple mitotic kinases (http://dx.doi.org/10.1371/journal.pone.0153518).
