Disclosed is a chalcone composition for treating diabetes and metabolic syndromes. In particular, the chalcone compound bound with 2-halogen in ring A significantly decreases the blood glucose level in the in vitro anti-diabetic effect experiment. In the in vivo animal model, the leading chalcone compound can prevent the progression of diabetes and control the blood glucose level, and there is no significant difference in the gains in body weight. Throughout the seven-week administration, there are no hepatic or renal toxicity observed.

A novel approach to biaryl bridged seven-membered carbocyclic scaffolds was developed by means of an intramolecular [3 + 2] cycloaddition process of in situ formed azomethine ylides from 2-cinnamoyl-2'-formyl biphenyl and diethyl aminomalonate hydrochloride. A range of biaryl bridged carbocyclic motifs with five-membered pyrrole ring bearing three steregenic centers was achieved with good to excellent

Disclosed are a composition for preventing and treating atherosclerosis which includes chalcone compound. In particular, the chalcone compound bound with 2-hydroxyl in ring A and 4′-methyoxy in ring B has versatile therapeutic potentials on anti-atherosclerosis by acting as PPARγ inducer, p44/42 MAPK inhibitor and cell cycle blocker and does not show toxicity to human aortic smooth muscle cells (HASMCs). In addition, the chalcone compound exhibits synergistic effect with the PPARγ ligand (rosiglitazone) to inhibit cell proliferation and the upregulation of cyclin D1, cyclin D3, interleukin-1β (IL-1β) and interleukin-6 (IL-6) induced by oxidized low density lipoprotein (Ox-LDL).
