Curcumin

Curcumin, also known as diferuloylmethane, natural yellow 3, or C.I. 75300, is the principal curcuminoid of the popular Indian spice turmeric, which is a small molecule, selective HAT inhibitor. It has shown to promote degradation of p300 and inhibits the acetyltransferases activity of purified p300 using either histone H3 or p53 as a substrate.
