Chidamide (CS055) is a novel and orally active benzamide class of histone deacetylase (HDAC) inhibitor that selectively inhibits activity of HDAC1, 2, 3 and 10, the enzymes that are involved and play an important role in tumor initiation and development in both tumor cells and their surrounding micro-environment. It was approved by the CFDA in December 2014 for the treatment of recurrent of refractory peripheral T-cell lymphoma. Reported hematological adverse events are: neutropenia, thrombocytopenia, leukopenia. Chidamide is under investigation as a potential agent for the treatment of other types of tumors.

Sample Use Guides

In Vivo Use Guide

30 mg (6 tablets) twice a week. The interval should not be less than 3 days, 30 min after breakfast.

Route of Administration: Oral

In Vitro Use Guide

At low concentrations (<1 uM), Chidamide induced G1 arrest in human leukaemia cell lines and primary myeloid leukaemia cells. At moderate concentrations (0.5 uM-2 uM), Chidamide induced differentiation, as determined by the increased expression of the myeloid differentiation marker CD11b. At relatively high concentrations (2 uM-4 uM), Chidamide potently induced caspase-dependent apoptosis.
