TOPK

OTS964 hydrochloride (OTS964) is a potent and selective TOPK inhibitor with potential anticancer activity.

OTS514 hydrochloride is a highly effective TOPK(T-LAK cell-originated protein kinase) inhibitor (IC50: 2.6 nM).

Ilaprazole (IY-81149) is a proton pump inhibitor used in the treatment of dyspepsia gastroesophageal reflux disease (GORD GERD) and duodenal ulcer. Studies also showed that Ilaprazole significantly prevented the development of reflux oesophagitis.

Ilaprazole sodium (IY-81149 sodium) , a substituted benzimidazole prodrug, is a selective and irreversible proton pump inhibitor. A weak base, Ilaprazole accumulates in the acidic environment of the secretory canaliculus of the gastric parietal cell where it is converted to an active sulfenamide form that binds to cysteine sulfhydryl groups on the luminal aspect of the proton pump hydrogen-potassium adenosine triphosphatase (H+ K+ ATPase), thereby inhibiting the pump's activity and the parietal cell secretion of H+ ions into the gastric lumen, the final step in gastric acid production.

Cephradine (Anspor) is a beta-lactam, first-generation cephalosporin antibiotic with bactericidal activity.

HI-TOPK-032 is an effective and specific inhibitor of TOPK.

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.
