Description: Inolitazone, also known as Efatutazone, CS-7017, and RS5444, is an orally bioavailable PAPR-gamma inhibitor with potential antineoplastic activity. Inolitazone binds to and activates peroxisome proliferation-activated receptor gamma (PPAR-gamma), which may result in the induction of tumor cell differentiation and apoptosis, as well as a reduction in tumor cell proliferation. PPAR-gamma is a nuclear hormone receptor and ligand-activated transcription factor controlling gene expression involved in such cellular processes as differentiation, apoptosis, cell-cycle control, carcinogenesis, and inflammation. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).
