[CAS NO. 97322-87-7]  Troglitazone (CS-045)

Troglitazone significantly inhibits cell growth by cell cycle arrest and apoptotic cell death. Troglitazone also downregulates surface expression of CD97, a novel dedifferentiation marker, in FTC-133 cells and upregulated sodium iodide symporter (NIS) mRNA in TPC-1 and FTC-133 cells. Troglitazone, a PPARγ agonist, induces antiproliferation and redifferentiation in thyroid cancer cell lines. Troglitazone induces Erk phosphorylation in human prostate cancer cells via a PPARγ-independent signaling pathway. TGZ(Troglitazone) up-regulates nitric oxide synthesis, induces the p53 pathway, inhibits cholesterol biosynthesis, induces p21 cyclin-dependent kinase inhibitor, has antioxidant function, and activates extracellular signal-regulated protein kinase (ERK) in a PPARγ-independent manner. TGZ induces Egr-1 expression by transcriptional and post-transcriptional regulation. Egr-1 induction by TGZ results in the increase of binding affinity and transactivation of the promoter containing Egr-1 consensus sequences, thereby possibly inducing other anti-tumorigenic proteins.
