| Outline of Final Research Achievements |
CaM kinase phosphatase (CaMKP/PPM1F/POPX2) is a Ser/Thr protein phosphatase that belongs to PPM family. Accumulating evidence shows possible involvement of CaMKP in cancer metastasis. In this study, we carried out large-scale screening of chemical library to find CaMKP-specific inhibitors, and investigated a mechanism of action of the inhibition. Subsequently, we showed that some of these inhibitors effectively suppressed migration of breast cancer cells despite the fact that they had no significant toxic effects on the cells. These data suggest that these CaMKP inhibitors or the derivatives are promising lead compounds for the development of novel cancer metastasis inhibitors without significant cytotoxicity.
