| Hazard Information | Back Directory | [Description]
C-646 (328968-36-1) is a potent and selective inhibitor of the histone acetyl transferase p300/CBP (Ki=400 nM ). Induces apoptosis in prostate cancer cells. C-646 enhances fear extinction memory and synaptic plasticity in mice. Promotes tau deacetylation reducing levels of pathogenic p-tau. Cell permeable. | [Uses]
C646 is an inhibitor for histone acetyltransferase p300 and may be a potential candidate for treating AML1-ETO (AE) positive acute myeloid leukemia (AML). It is shown that C646 inhibited cellular proliferation, reduced colony formation, evoked partial cell cycle arrest in the G1 phase, and induced apoptosis in AE-positive AML cell lines and primary blasts isolated from leukemic mice and AML patients. | [Definition]
ChEBI: A pyrazolone that is 5-methyl-4-methylene-2-(p-carboxyphenyl)-2,4-dihydro-3H-pyrazol-3-one in which the exocyclic carbon of the methylene group is attached to a 5-(4,5-dimethyl-2-nitrophenyl)furan-2-yl group by a single bond
C646 is a potent, cell permeable and selective competitive inhibitor of p300 and CBP (p300/CBP) histone acetyltransferases. | [Biochem/physiol Actions]
C646 is a potent, cell permeable and selective inhibitor of p300 and CBP (p300/CBP) histone acetyltransferases. Inhibition of p300/CBP by C646 affects the activity of a variety of transcriptional factors such as NF-κB, p53 and MyoD that are associated with physiology, disease processes, hippocampal synaptic plasticity, spatial memory and contextual fear. | [storage]
