Tolazamide (U-17835)
(Synonyms: 甲磺氮草脲; U-17835) 目录号 : GC32400
A sulfonylurea inhibitor of SUR1/KIR6.2
Cas No.:1156-19-0
Sample solution is provided at 25 µL, 10mM.
Tolazamide is a first generation sulfonylurea that inhibits sulfonylurea receptor 1 (SUR1) linked to the inwardly rectifying potassium channel (KIR6.2; IC50 = 4.2 ?M in HEK293 cells transfected with the human receptor).1 It has no effect on glucose uptake in L6 rat skeletal muscle cells when used at a concentration of 0.6 mg/mL but enhances glucose uptake two-fold when used in combination with insulin.2 In vivo, tolazamide (128 mg/kg) reduces glomerulosclerosis and albumin excretion in a rat model of insulin-dependent diabetes induced by streptozotocin .3 Formulations containing tolazamide have been used in the treatment of type 2 diabetes.

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。
