Procyanidin A2
(+)-Proanthocyanidin A2 is a polyphenol oxidase (PPO) substrates isolated from grape seeds (Vitis vinifera L). Proanthocyanidins represent one of the major groups of plant polyphenols. A2 could isolated from the acetone-water extract (7:3, v/v) of horse chestnut seed shells (Aesculus hyppocastanum), after extraction with ethyl acetate, by combined LH-20 chromatography and TLC on Silicagel 60 plates. Group: Pharmaceutical. Alternative Names: 8,?14-Methano-2H,?14H-1-benzopyrano[7,?8-d]?[1,?3]?benzodioxocin-3,?5,?11,?13,?15-pentol, 2,?8-bis(3,?4-dihydroxyphenyl)?-3,?4-dihydro-, (2R,?3R,?8S,?14R,?15R)?-; 8,14-Methano-2H,14H-1-benzopyrano[7,8-d][1,3]benzodioxocin-3,5,11,13,15-pentol, 2,8-bis(3,4-dihydroxyphenyl)-3,4-dihydro-, [2R-(2α,3α,8β,14β,15R*)]-; (2R,3R,8S,14R,15R)-2,8-Bis(3,4-dihydroxyphenyl)-3,4-dihydro-8,14-methano-2H,14H-1-benzopyrano[7,8-d][1,3]benzodioxocin-3,5,11,13,15-pentol; (+)-Epicatechin-(4β-8,2β-O-7)-epicatechin; Dimeric catechin.

Procyanidin B1
Procyanidin B1 is a procyanidin dimer found in Cinnamomum verum, in Uncaria guianensis, and in Vitis vinifera or in peach. Procyanidin B1 (PB1) inhibits infection by vesicular stomatitis virus and HCV pseudotype virus in Huh-7 cells, with 50% effective concentrations of 29 and 15 μM, respectively. No inhibitory effects were observed in each component of PB1. PB1 does not interfere with viral entry or receptor expression, but inhibits HCV RNA synthesis in a dose-dependent manner. Uses: Antioxidant;anti-inflammatory. Group: Pharmaceutical. Alternative Names: Proanthocyanidin B1; Endotelon; Procyanidin dimer B1. CAS No. 20315-25-7. Pack Sizes: 10 mg. Product ID: B2703-464484.

Procyanidin C1
Procyanidin C1 is extracted from the fruits of Vitis vinifera L. It is a B type proanthocyanidin and found in grape. It belongs to a polyphenol flavonoid epicatechin trimer. It can decrease cytokine production of mast cells and Fc epsilon RI-mediated degranulation in vitro dose-dependently. It inhibits ROS generation in stimulated mast cells and the tyrosine phosphorylation of Syk and linker for activation of T cells. It may be used for the treatment of cardiovascular diseases and may be useful as a lead compound to develop inhibitors of cancer metastasis and other diseases related to EMT. It has HIV-related, antioxidant and anti-inflammatory effects. It also inhibits the activity of 15-lipoxygenase and α-glucosidase. It could scavenge 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radicals. Group: Pharmaceutical. Alternative Names: Procyanidol C1; (2R,2'R,2''R,3R,3'R,3''R,4R,4'S)-2,2',2''-tris(3,4-dihydroxyphenyl)-3,3',3'',4,4',4''-hexahydro-[4,8':4',8''-ter-2H-1-benzopyran]-3,3',3'',5,5',5'',7,7',7''-nonol; Proanthocyanidin C1; Cinnamtannin A1; [Epicatechin-(4beta->8)]2-epicatechin.
