产品描述: | GSK1016790A (GSK101)是一种新型的、有效的TRPV4激活剂,其在人脉络丛上皮细胞中的EC50为34 nM |
靶点: |
hTRPV4(In HEK cells):2.1 nM; mTRPV4(In HEK cells):18 nM;CalciumChannel; TRP/TRPVChannel |
体外研究: |
在浓度为1 nM以上时,GSK1016790A在表达鼠源和人源TRPV4的HEK细胞中引发钙离子(Ca2+)的流入(EC50分别为18和2.1 nM),引起剂量依赖式的TRPV4全细胞电流的激活。它可以在多种类型细胞中刺激、激活TRPV4,包括内皮细胞、尿路平滑肌细胞、尿道上皮细胞、以及过表达TRPV4的HEK293细胞。GSK1016790A特异性激活TRPV4,引发质膜上该通道的表达下调、快速部分脱敏 |
体内研究: |
GSK1016790A在高肺血管张力的情况下,使全身系统的血管阻力以及肺部血管阻力急剧下降[3]。GSK1016780A激活TRP4,引起血管舒张、渗漏和组织出血 |
细胞实验: |
Cell lines: 脉络丛上皮细胞 Concentrations: 10 nM Incubation Time: 20分钟 Method: 用DMSO、10 nM GSK处理或者预先处理以1 mM HC、再用10 nM GSK处理CPECs(脉络丛上皮细胞)20分钟。处理过后,这些细胞被固定、用Coomassie Brilliant Blue进行染色 |
动物实验: |
Animal Models: Adult male Sprague-Dawley rats Dosages: 2, 4, 6, 8, 10, and 12 μg/kg Administration: 静脉注射 |
