MG149

MG149 is a selective and potent Tip60 inhibitor with IC50 of 74 uM, similar potentcy for MOF (IC50= 47 uM); little potent for PCAF and p300 (IC50 >200 uM). MG 149, at 200 μM, inhibites about 90% of Tip60 activity but has no inhibitory impact on p300 and PCAF. MG 149 is essentially competitive with Ac-CoA and noncompetitive with the histone substrate. MG149 inhibits acetyltransferase activity of nuclear extract from tissue samples from different brain regions in mice. MG149 inhibits the p53 and the NF-κB pathways.
