Product Description: Procyanidin B2, 3,3'-di-O-gallate is an active constituent. Procyanidin B2, 3,3'-di-O-gallate can be isolated from grape seed extract (GSE) procyanidin mix. Procyanidin B2, 3,3' -di-o-gallate target cancer stem cells (CSCs) in prostate cancer (PCa). Procyanidin B2, 3,3'-di-O-gallate targets both unsorted and sorted CSCs at lower doses. Procyanidin B2, 3,3'-di-O-gallate strongly suppresses the constitutive as well as Jagged1 (Notch1 ligand)-induced activated Notch1 pathway[1].
Formula: C44H34O20
