产品介绍
Astragaloside A 是从黄芪中分离得到的初级纯皂苷,已广泛用于心血管疾病的治疗。

产品描述

Astragaloside A (Astragaloside IV) is the primary pure saponin isolated from Astragalus membranaceus, which has been widely used for the therapy of cardiovascular diseases.

体外活性

Astragaloside IV improves post-ischemic heart function and ameliorated reperfusion arrhythmias accompanied by a significant increase in myocardial antioxidative enzyme superoxide dismutase activity in rat hearts in vitro. While, Astragaloside IV's protective effect on heart function can be partially abrogated by the nitric oxide synthase inhibitor, Nomega-nitro-L-arginine methyl ester. [1]

体内活性

Astragaloside IV significantly reduces infarct size in dogs subjected to coronary ligation in vivo. [1] Astragaloside IV attenuates isoproterenol-induced subendocardial necrosis, serum lactate dehydrogenase and creatine kinase activation, and lipid oxide product malondialdehyde formation in rats. It also reduces sarcoplasmic reticulum Ca(2+)-uptake ability and Ca(2+)-ATPase (SERCA2a) activity as well as SERCA2a mRNA expression in myocardial injury rats. [2]

激酶实验

In vitro PI3Kγ Kinase Assay: Human PI3Kγ (100 ng) is incubated at RT with kinase buffer (10 mM MgCl2, 1 mM β-glycerophosphate, 1 mM DTT, 0.1 mM Na3VO4, 0.1% Na Cholate and 15 M ATP/100 nCi γ[33]ATP, final concentrations) and lipid vesicles containing 18 M PtdIns and 250 M of PtdSer (final concentrations), in the presence of AS-252424 or DMSO. Kinase reaction is stopped by adding 250 g of Neomycin-coated Scintillation Proximity Assay (SPA) beads and preceded.
