Astragaloside A (Astragaloside IV), a pure saponin isolated from Astragalus membranaceus Bge, exhibits several pharmacological actions, such as anti-hypertension, positive inotropic action, anti-inflammation, and anti-myocardial injury [1, 2]. Astragaloside IV has been widely used for the treatment of cardiovascular disorders and kidney disease [3].

In vitro: Astragaloside IV (2-40 μM) dose-dependently decreased TGF-β-induced a-SMA, fibronectin, CTGF, collagen I and III expression, up-regulated Smad7, but decreased p-Smad2 and p-Smad3 expression in NRK-49F cells [2]. Moreover, Astragaloside IV prevented tubular epithelial apoptosis partially through inhibiting MAPK pathway activity, thereby ameliorating renal fibrosis [3].

In vivo: Astragaloside IV (5 and 10 mg/kg/day, intraperitoneal injection) reduced serum lactate dehydrogenase and creatine kinase enzyme levels and attenuated this reduction in the Ca2+-ATPase activity in rats [1]. Astragaloside IV (3.33, 10, and 33 mg/kg, intraperitoneal injection) treatment attenuated renal damage and improved renal function through inhibiting TGF-β/Smad signaling pathway in a dose-dependent manner in unilateral ureteral obstruction kidneys [2].
