In vitro(体外研究)
C646 is an inhibitor for histone acetyltransferase, inhibits p300 with a Ki of 400 nM and is selective versus other acetyltransferases. C646 produces 86% inhibition of p300 in vitro at 10 μM. C646 is a classical reversible p300 inhibitor. C646 treatment (25μM) reduces histone H3 and H4 acetylation levels and abrogates TSA-induced acetylation in cells. C646 (20μM) induces apoptosis in androgen-sensitive and castration-resistant prostate cancer cell lines by interfering with AR and NF-kB pathways. C646 blocks dynamic acetylation of H3K4me3 globally in mouse and fly cells, and locally across the promoter and start-site of inducible genes in the mouse, thereby disrupting RNA polymerase II association and the activation of these genes.
In vivo(体内研究)
C646 infused into the ILPFC immediately after weak extinction training enhances the consolidation of fear extinction memory. C646 attenuates mechanical allodynia and thermal hyperalgesia, accompanied by a suppressed COX-2 expression, in the spinal cord.
