Scoparone

Scoparone is a coumarin that has been found in A. capillaris and has diverse biological activities.^1,2,3,4,5 It inhibits angiotensin II-induced extracellular matrix (ECM) remodeling and cell proliferation and reduces levels of collagen I and fibronectin in isolated primary neonatal rat cardiac fibroblasts when used at concentrations ranging from 1 to 10 ?M.¹ Scoparone suppresses PDGF-BB-induced rat aortic smooth muscle cell (RASMC) migration and wound healing in a scratch assay.² In vivo, scoparone (3.5 mg/kg) reduces vascular neointima formation in a rat model of carotid artery balloon injury. Scoparone (80 mg/kg) reduces hepatocyte apoptosis, liver fibrosis, serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and hepatic triglyceride levels in a mouse model of non-alcoholic steatohepatitis (NASH) induced by a methionine- and choline-deficient (MCD) diet.³ It reduces ulcer lesion area in a rat model of HCl- and ethanol-induced gastric ulcers.⁴ Scoparone also inhibits passive cutaneous anaphylaxis in rats.⁵
