    Product Description

    (+)-Catechin is a polyketide synthase-derived polyphenolic flavonoid that has been found in V. vinifera and has diverse biological activities.1,2,3,4 It inhibits COX-1 (IC50 = 1.4 µM) and lipid peroxidation induced by AAPH (Item No. 82235) when used at a concentration of 20 µM.2,3 (+)-Catechin inhibits the proliferation of MCF-7, T47D, and MDA-MB-231 breast cancer cells (IC50s = 0.4, 0.1, and 9.3 pM, respectively) and the binding of estradiol to the estrogen receptor (ER) and progesterone receptor (PR) in MCF-7 cells (IC50s = 22.2 and 38.3 pM, respectively).4
