HIDE SMILES / InChI
OTS-167 is a maternal embryonic leucine zipper kinase (MELK) inhibitor which demonstrated antitumor properties in laboratory tests. It is being developed as an anti-cancer drug. The compound has been shown to suppress the growth of breast, lung, pancreatic and prostate cancer cells that express high levels of the MELK protein. OTS167 reached phase II clinical trials in patients with AML, ALL, advanced MDSs, advanced MPNs, or advanced CML and phase I in patients with breast cancer.
