Procyanidin B3 (Standard)

Procyanidin B3 (Standard) is the analytical standard of Procyanidin B3. This product is intended for research and analytical applications. Procyanidin B3 is a natural product with antioxidant activity and oral bioavailability, possessing good blood-brain barrier penetration. Procyanidin B3 is a selective inhibitor of histone acetyltransferase (HAT) . By inhibiting p300 HAT-mediated acetylation of the androgen receptor (androgen receptor) . Procyanidin B3 alleviates intervertebral disc degeneration (IVDD) by inhibiting the formation of the TLR4/MD-2 complex. Procyanidin B3 can be used in research on prostate cancer and arthritis[1][2][3][4][5].
