| physiological effects | procyanidins are a good oxygen free radical scavenger and lipid peroxidation inhibitor. their main functions are: ① effectively scavenging superoxide anion radicals and hydroxyl radicals, etc., and can also interrupt the free radical chain reaction. ② Participate in the metabolism and protein phosphorylation of phospholipids and arachidonic acid, protect lipids from peroxidation damage. ③ It is a powerful metal chelating agent, which can chelate metal ions and form inert compounds in the body. ④ Protect and stabilize vitamin C, which helps the absorption of vitamin C. This information is edited and sorted out by Yalin. |
| biological activity | Procyanidin B3 is a natural product, a specific inhibitor of histone acetyltransferase (HAT), which can bind to other sites of p300 instead of inactive sites to selectively inhibit p300-mediated acetylation of androgen receptors. Procyanidin B3 had no effect on HDAC or histone methyltransferase (HMT). |
| target | p300 |
| use | used for content determination/identification/pharmacological experiments, etc. |
