trans-Chalcone, isolated from Aronia melanocarpa skin, is a biphenolic core structure of flavonoids precursor. trans-Chalcone is a potent fatty acid synthase (FAS) and α-amylase inhibitor. trans-Chalcone causes cellcycle arrest and induces apoptosis in the breastcancer cell line MCF-7. trans-Chalcone has antifungal and anticancer activity[1][2][3].

trans-Chalcone competitively inhibits porcine pancreatic α-amylase with a Ki of 48 μM[2]. trans-Chalcone (30.23-98.03 μM; 24 hours) induces cell cycle arrest and apoptosis in MCF-7 cells[1]. trans-Chalcone (20-80 μM; 24, 48 hours) reduces the expression of the apoptosis-related protein Bcl-2[1]. trans-Chalcone (58.25 μM; 6, 24 hours) has greater inhibition of Bcl-2, induction of APAF1 and BAX, and strong induction of CIDEA in 24 hours[1]. trans-Chalcone (24 hours) inhibits MCF-7 cell viability (IC20=30.23 μM; IC50=58.25 μM; IC80=98.03 μM). trans-Chalcone (48 h) has IC50s of 41.53 μM and 48.41 μM for MCF-7 and 3T3 cell lines, respectively. trans-Chalcone exhibits a pronounced cytotoxicity activity[1].
