产品描述:基本信息 产品编号: S10939  产品名称: SR33805 CAS: 121345-64-0   储存条件 粉末 -20℃ 四年     分子式: C32H40N2O5 溶于液体 -80℃ 6个月 分子量: 564.74 -20℃ 1个月 化学名:  3,4-Dimethoxy-N-methyl-N-[3-[4-[[1-methyl-2-(1-methylethyl)-1H-indol-3-yl]sulfonyl]phenoxy]propyl]benzeneethanamine Solubility (25°C):   体外:   DMSO   Ethanol   Water   体内(现配现用):   <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;⼀旦配成溶液,请分装保存,避免反复冻融造成的产品失效。   制备储备液   浓度   溶液体积 质量   1mg   5mg   10mg 1mM 1.7707mL 8.8536mL 17.7073mL 5mM 0.3541mL 1.7707mL 3.5415mL 10mM 0.1771mL 0.8854mL 1.7707mL   生物活性 产品描述 一种有效的Ca2+通道拮抗剂,在去极化和极化条件下的EC50值分别为4.1nM和33nM。SR33805阻止L型而不是T型Ca2+通道。SR33805可用于研究急性或慢性心脏衰竭。 靶点 type calcium channel 4.1nM (EC50,in depolarized conditions) L-type calcium channel 33nM (EC50,in polarized conditions)   体外研究 SR33805 (0.01-10µM;3 d) inhibits growth factor-induced proliferation of SMC (0.2050<0.46µM) in a dose-dependent manner.SR33805 (10µM;10 min) restores the myocardial infarction (MI)-altered cell shortening without affecting the Ca2+ transient amplitude.SR33805 (10µM) decreases the activity of recombinant PKA. Cell Viability Assay Cell Line: Smooth muscle cells (SMC) Concentration: 0.01,0.1,1,10µM Incubation Time: 3 days Result: Inhibited in a dose-dependent manner FCS-,bFGF and PDGF-induced proliferation of porcine SMC with IC50s of 0.26±0.08,0.46±0.1 and 0.20±0.04µM,respectively. 体内研究 SR33805 (20mg/kg;a single i.p.) improves end-systolic strain and fractional shortening of MI hearts in rats.SR33805 (5mg/kg/day;p.o.for 38 d) significantly reduces intimal hyperplasia in pigs. Animal Model: Male Wistar rats (5 weeks) are subjected to coronary artery ligature Dosage: 0.2,2,20mg/kg Administration: A single i.p.injection Result: Increased significantly both end-systolic strain (ESS) and fractional shortening (FS) by about +38 and +26%,respectively at the dose of 20mg/kg.Did not affect other contractile parameters.
