Product Introduction
Bioactivity
| Name | Procyanidin A1 |
| Description | Procyanidin A1 (Proanthocyanidin A1) has antiallergic effects, it inhibits degranulation downstream of protein kinase C activation or Ca2+; influx from an internal store in RBL-2H3 cells. |
| In vitro | We found that a peanut-skin extract (PSE) inhibits the degranulation induced by antigen stimulation of rat basophilic leukemia (RBL-2H3) cells. A low-molecular-weight fraction from PSE, PSEL, also had inhibitory activity against allergic degranulation. A main polyphenol in PSEL was purified by gel chromatography and fractionated by YMC-gel ODS-AQ 120S50 column. Electrospray ionization mass spectrometry (ESI-MS) analysis of the purified polyphenol gave m/z 599 [M+Na]?. Based on the results of 1H-NMR, 13C-NMR spectra, and optical rotation analysis, the polyphenol was identified as Procyanidin A1. It inhibited the degranulation caused by antigen stimulation at the IC50 of 20.3 μM. Phorbol-12-myristate-13-acetate (PMA) and 2,5,-di(tert-butyl)-1,4-hydroquinone (DTBHQ)-induced processes of degranulation were also inhibited by Procyanidin A1[1] |
