用途: Astragaloside A is one of the major active constituents of Astragalus membranaceus in Traditional Chinese Medicine; has been widely used to treat ischemic diseases.IC50 value: Target: in vitro: AS-IV treatment promotes umbilical vein endothelial cells (HUVEC) proliferation, migration, and tube formation. AS-IV treatment also activates JAK2/STAT3 and ERK1/2 signaling pathways, and up-regulates endothelial nitric oxide synthase (eNOS) expression and nitric oxide (NO) production [1]. Administration of astragaloside IV (16, 32, and 64 μM) 1 h prior to lipopolysaccharide stimulation dose-dependently attenuated cardiac hypertrophy induced by lipopolysaccharide. Further studies demonstrated that astragaloside IV inhibited the increment of the resting intracellular free Ca2+, and its effect was similar to verapamil [2]. ASI could inhibit cells apoptosis induced by high glucose (25mmol/L) in dose-dependent and time-dependent manners. ASI also inhibited high glucose-induced expression of TGF-β1 and activation of p38 MAPK pathway at the protein level. Furthermore, ASI increased HGF production in human tubular epithelial cells [3].in vivo: the growth of tumor was suppressed by AS-IV treatment in vivo. AS-IV also could down-regulate regulatory T cells (Tregs) and up-regulate cytotoxic T lymphocytes (CTLs) in vivo and in vitro[4]. As an in vivo model, mice subjected to unilateral ureteral obstruction (UUO) were administered AS-IV (20 mg/kg) by intraperitoneal injection for 7 days. AS-IV significantly alleviated renal mass loss and reduced the expression of α-smooth muscle actin, fibronectin, and collagen IV both in vitro and in vivo [5]. 物理化学性质: CAS号:83207-58-3 常用中文名:黄芪甲苷A(黄芪甲苷 IV) 常用英文名:Astragaloside A 分子式:C41H68O14 分子量:784.970 密度:1.4±0.1 g/cm3 沸点:895.7±65.0 °C at 760 mmHg 熔点:284-286ºC 闪点:495.5±34.3 °C 储存条件:2~8℃ |
