YM-90K is an AMPA receptor antagonist (Ki = 0.084 μM in a radioligand binding assay using rat brain membranes).1 It is selective for AMPA over kainate, NMDA-sensitive glutamate, and strychnine-insensitive glycine receptors (Kis = 2.2, >100, and 37 μM, respectively). Intrastriatal administration of YM-90K inhibits AMPA-induced decreases in choline acetyltransferase (ChAT) activity in rat striatum ex vivo in a dose-dependent manner. It inhibits audiogenic seizures in susceptible DBA/2 mice with a minimum effective dose of 3 mg/kg when administered intraperitoneally. Intravenous infusion of YM-90K (20 mg/kg per hour for 4 hours) reduces infarct size in a rat model of focal cerebral ischemia induced by thrombotic middle cerebral artery occlusion (MCAO) in rats.2

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。
