Bavachin is an acyl-coenzyme A: cholesterol acyltransferase inhibitor [1].

Acyl-coenzyme A: cholesterol acyl transferase (ACAT) is an enzyme responsible for the intracellular esterification of free cholesterol with fatty acids and plays dominant roles in intestinal absorption of cholesterol, hepatic production of lipoproteins and accumulation of cholesteryl ester within macrophages and smooth muscle cells. [1].

Bavachin showed a significant inhibition of ACAT enzyme. The IC50 value of bavachin was 86.0 μM in the ACAT assay system using rat liver microsome [1]. Bavachin is a flavonoid first isolated from Psoralea corylifolia that has been used as a traditional medicine in Asia. In CV-1 cells transfected with plasmids ERα or ERβ, bavachin showed ER ligand binding activity with an EC50 of 320 nM and 680 nM, respectively. Bavachin increased the mRNA levels of estrogen-responsive genes such as pS2 and PR, and decreased the protein level of ERα by proteasomal pathway [2]. Bavachin activated gene expression of proliferator-activated receptorγ (PPARγ), adipogenic transcriptional factors, and CCAAT/enhancer binding protein-α (C/EBPα). Bavachin increased adiponectin expression and secretion in adipocytes. Bavachin increased insulin-induced glucose uptake by differentiated adipocytes and myoblasts. In differentiated adipocytes, bavachin enhanced glucose uptake [3].
