Biochem/physiol Actions

CTPB was a first known small molecular activator of histone acetyltransferase p300. CTB is a simplified analog of CTPB with comparable or higher activity. The compound activates the histone acetyltransferase (HAT) activity of p300/EP300/E1A binding protein.
Small molecule activators of HAT such as CTB (N-(4-Chloro-3-trifluoromethyl-phenyl)-2-ethoxy-benzamide) is useful for altering chromatin acetylation directly. It might serve as a therapeutic agent for treating the complications of cognitive dysfunction including neuropsychiatric, neurodevelopmental and neurodegenerative diseases.

Neuroinflammation is a common feature in renovascular, obesity-related, and angiotensin II mediated hypertension. There is evidence that increased release of the pro-inflammatory cytokine tumour necrosis factor-α (TNF-α) contributes to the development of the hypertension, but the underlying neural mechanisms are


Histone Modification and Chromatin Remodeling | Epigenetics

Epigenetic modifications are thought to occur through two key interconnected processes—DNA methylation and the covalent modification of histones.
