Delphinidin (chloride) is an anthocyanidin, a natural plant pigment which serves as the precursor of certain anthocyanins that provide the blue-red colors of flowers, fruits, and red wine.[1] Delphinidin induces the release of nitric oxide by vascular endothelium, causing vasorelaxation.[2] It also inhibits signaling through epithelial growth factor receptors, suppressing the expression of estrogen receptor α and inducing both apoptosis and autophagy at a dose of 1-40 μM.[3],[4] Delphinidin also inhibits the histone acetyltransferase activities of p300/CBP (IC50 = ~ 30 μM).[5]
