Description: Ivaltinostat, also known as CG200745, is a novel hydroxamate-based pan-histone deacetylase inhibitor (HDACI). Like other inhibitors, CG200745 has the hydroxamic acid moiety to bind zinc at the bottom of catalytic pocket. CG200745 inhibited deacetylation of histone H3 and tubulin as much as vorinostat and belinostat did. CG200745 also inhibited growth of prostate cancer cells, increased sub-G1 population, and activated caspase-9, -3 and -8 in LNCaP, DU145 and PC3 cells. These results indicate that CG200745 induces apoptosis. The preclinical results show that combination treatment with docetaxel and new HDACI, CG200745, potentiated anti-tumor effect in hormone-refractory prostate cancer (HRPC) cells via activation of apoptosis.
