OTS514

Description: OTS514 (OTS514 Hydrochloride) is a potent TOPK inhibitor. OTS514 exhibits a growth-suppressive effect on small cell lung cancer. OTS514 effectively suppressed the growth of SCLC cell lines (IC50: 0.4 ~ 42.6 nM). Treatment with OTS514 suppressed forkhead box protein M1 (FOXM1) activity. OTS514 treatment reduced CD90-positive SCLC cells and showed a higher cytotoxic effect against lung sphere-derived CSC-like SCLC cells. Target: Apoptosis, TOPK. Smiles: C[C@@H](CN)c1ccc(cc1)-c1c(O)cc(C)c2[nH]c(=O)c3sccc3c12. References: Ikeda Y, Park JH, Miyamoto T, Takamatsu N, Kato T, Iwasa A, Okabe S, Imai Y, Fujiwara K, Nakamura Y, Hasegawa K.
