Phytochemical name or plant extracts Condensed tannins
PMID 15670892
Literature evidence The potential anti-angiogenic activities of water-soluble condensed tannins isolated from black beans were evaluated using HEL 299 normal human fibroblast lung cells, Caco-2 colon, MCF-7 and Hs578T breast, and DU 145 human prostatic cancer cells.

Gene or Protein evidence After 24h exposure to Caco-2, MCF-7, Hs578T, and DU 145 cancer cells, water-soluble black bean condensed tannins at 24 microM suppressed fetal bovine serum stimulated cell migration, the secretion of matrix metalloproteinase-2 (MMP-2 or gelatinase A), matrix metalloproteinase-9 (MMP-9 or gelatinase B), and vascular endothelial growth factor VEGF(165) receptor expression by the cancer cells in the conditioned media.
Target pathways NA
IC50 NA
Potency NA
Cell line/ mice model HEL 299, Caco-2, MCF-7, Hs578T, DU 145
Additional information  The secretion of pro-MMP-2 and pro-MMP-9 was measured as an indicator of the inhibitory activity of condensed tannins against Caco-2, MCF-7, Hs578T, and DU 145 cancer cells.MCF-7 and Hs578T breast cancer cells showed declined cell viability with increasing tannin concentration
