MG 149
Based on 14 publication(s) in Google Scholar
MG149 (Tip60 HAT inhibitor) 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 inhibits KAT8 and blocks PINK1 kinase activity. MG149 inhibits the phosphorylation of Parkin and ubiquitin, thereby suppressing the initiation of PINK1-dependent mitophagy. MG 149 can reverse chronic restraint stress (CRS) induced hypertension and related molecular changes. MG 149 commonly used in research on diseases such as hypertension and Parkinson's disease.

MG 149 (Tip60 HAT inhibitor), at 200 μM, inhibited about 90% of Tip60 activity but had no inhibitory impact on p300 and PCAF. MG 149 was essentially competitive with Ac-CoA and noncompetitive with the histone substrate. HAT inhibition studies with MG 149 demonstrated that both compounds inhibited the HAT activity of the nuclear extracts of different regions significantly (p < 0.05)[1].
MG 149 (100 μM, 3 h) inhibits the activation of the PINK1/Parkin pathway in POE SH-SY5Y cells[2].
