Histone deacetylase inhibitor II. A cell-permeable second generation hybrid polar agent that inhibits HDAC activity. Inhibition is believed to arise as a result of the binding of the hydroxamic moiety to the active site zinc. Induces apoptosis and Fas/Fas ligand expression in human neuroblastoma. | [Uses]

cbha is a potent and selective inhibitor with id50 values of 0.01 and 0.07 μm for hdac1 and hdac3, respectively [1].histone deacetylases (hdacs) are a class of enzymes that remove acetyl groups from lysine amino acid on histone, allowing the histones to wrap the dna more tightly. hdac inhibitors hyperacetylate histones and increase transcriptional activity in target genes. hdac inhibitors have both apoptotic and differentiating effects on various tumor cells [2].m-carboxycinnamic acid bishydroxamide (cbha) is a potent and selective hdac inhibitor. cbha is a hybrid polar compound that is synthesized to induce terminal differentiation and/or apoptosis in various transformed cells. in mel cells, cbha caused accumulation of acetylated histone h4 [1]. in neuroblastoma cell lines, cbha induced acetylated histone h3 and h4 accumulation. cbha also led to extensive cell death with ld50 ranged between 1 μm and 4 μm, and induced apoptosis [2].in human neuroblastoma xenograft scid mice, cbha (100 mg/kg and 200 mg/kg) resulted in reductions of average final tumor volume of ~50% and 75%, respectively [3]. | [References]
