HC TOXIN

Description

HC Toxin is a cell-permeable, reversible inhibitor of histone deacetylases (HDACs) (IC₅₀ = 30 nM). Through its effects on HDACs, HC toxin has been shown to up-regulate the expression of 15-lipoxygenase-1 in colorectal cancer cells and induce fetal hemoglobin in human primary erythroid cells. HC Toxin is a cyclic tetrapeptide first isolated from H. carbonum (now C. carbonum), a pathogen of maize.

Uses

HC Toxin is an HDAC inhibitor. Cyclic tetrapeptide[1] fungal toxin selectively toxic to plants with susceptible host genotype (2)

Definition

ChEBI: A homodetic cyclic tetrapeptide made up from L-alanyl, D-alanyl, L-prolyl and 2-amino-8-oxo-9,10-epoxydecanoyl residues.
