Biological Activity

[Description]:

Procyanidin B3 is a natural product, acts as a specific HAT inhibitor, binds to the other site of p300 instead of the active site, selectively inhibits p300-mediated androgen receptor acetylation. Procyanidin B3 has no effect on HDAC or HMT (histone methyltransferase)[1].
