Biological Context

(−)-Epicatechin is a polyketide synthase-derived polyphenol flavonoid that has been found in T. cacao and has diverse biological activities.^1,2,3,4,5 It scavenges DPPH radicals in a cell-free assay when used at a concentration of 5 µM.² (−)-Epicatechin inhibits COX-1 (IC50 = 3.2 μM).⁶ It acts synergistically with epigallocatechin gallate to induce apoptosis in, and reduce the proliferation of, PC-9 lung cancer cells when used at a concentration of 200 µM.⁴ (−)-Epicatechin (80 mg/kg) reduces LPS-induced increases in plasma creatinine and urea levels in a rat model of renal inflammation.⁵
