Cas No.:106133-20-4
Sample solution is provided at 25 µL, 10mM.
Tamsulosin is a potent antagonist of α1-adrenergic receptors (α1-ARs; Ki = 0.229 nM in a radioligand binding assay).1 It is 3,800-fold selective for α1-ARs over α2-ARs (Ki = 871 nM). Tamsulosin antagonizes norepinephrine-induced contraction of isolated rabbit aorta (pA2 = 10.11) but has no effect on contraction stimulated by histamine, serotonin , angiotensin II , or prostaglandin F2α . In vivo, tamsulosin reverses the pressor effect of phenylephrine in pithed rats. It reversibly reduces fertility in male rats when administered at a dose of 0.15 mg/kg.2 Tamsulosin (1-100 μg/kg) also reduces prostatic pressure in a dose-dependent manner with minimal hypotensive effects in anesthetized dogs.3 Formulations containing tamsulosin have been used for the treatment of benign prostatic hyperplasia.

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。
