A flavanol dimer with diverse biological properties
Cas No.:41743-41-3
Sample solution is provided at 25 µL, 10mM.
Procyanidin A2 is a natural flavanol dimer of (-)-epicatechin that is found in the horse chestnut (A. hippocastanum), mountain cranberry (V. vitis-idaea), and other fruits with antioxidant, anti-inflammatory, antibacterial, antiproliferative, and antidiabetic properties. It scavenges 2,2-diphenyl-1-picrylhydrazyl radicals (IC50 = 5.08 μM) and inhibits STAT3 activation induced by platelet derived growth factor (PDGF) in primary rat vascular smooth muscle cells (VSMCs) when used at a concentration of 30 μg/ml. Procyanidin A2 inhibits growth of S. aureus and E. coli (MICs = 62.5 and 62.5 μg/ml, respectively) and proliferation of human HepG2 liver hepatocellular carcinoma and HeLa cervical cancer cells (EC50s = 62.19 and 66.07 μg/ml, respectively). It also increases insulin secretion from primary mouse pancreatic islets when used at a concentration of 10 μM in vitro and inhibits bisphenol A-induced glucose increases in fasted mice when administered at a dose of 10 μmol/kg per day.

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
