产品描述: NS 11021 is a potent and specific Ca2+-activated big-conductance K+ Channels (KCa1.1 channels) activator. NS 11021 at concentrations above 0.3 μM activates KCa1.1 in a concentration-dependent manner by parallelshifting the channel activation curves to more negative potentials
靶点: Ca2+-activated big-conductance K+ Channels
体外研究: NS 11021 (1-30 μM) increases the current of hKCa1.1 from 2 μA to 4 μA at the concentration of 3 μM and can activate the hKCa1.1 expression channel in a dose-dependent manner in X. laevis oocytes. NS 11021 (3 μM) increases hKCa1.1 current for channels by 171 % which repeatedly shifts between open and closed structures while increases the hKCa1.1 current by 187 % for channels kept in closed conformation in X. laevis oocytes. NS 11021 (0-10 μM) can enhance hKCa1.1 currents in a concentration-dependent manner in monoclonal HEK293 cells stably expressing hKCa1.1. NS 11021 (5 or 50 μM) has no effect on resting membrane potential (RMP), while significantly increasing action potential (AP) rise time in a dose-dependent manner in frogs gastrocnemius muscles. NS 11021 completely reverses the deleterious effects of hydrogen peroxide on the AP repolarization phase in skeletal muscle fibers. NS 11021 (1 μM) effectively attenuates mitoBK (mitochondrial big-conductance calcium-activated K+) channel damage, mitochondrial respiratory dysfunction, depolarization, superoxide production and cell death induced by CS + RW (cold storage (18 h) and rewarming (2 h)) in rat kidney proximal tubular epithelial (NRK) cells
体内研究: NS 11021 (1-30 μM) 在浓度为 3 μM 时将 hKCa1.1 的电流从 2 μA 增加到 4 μA,并且可以在 X. laevis 卵母细胞中以剂量依赖的方式激活 hKCa1.1 通道。。
NS 11021 (3 μM) 使通道的 hKCa1.1 电流增加 171%,这会在开放和封闭结构之间反复转换,同时增加 hKCa1。对于在 X. laevis 卵母细胞中保持闭合构象的通道,电流增加了 187%。
NS 11021 (0-10 μM) 可以浓度依赖性方式增强稳定表达 hKCa1.1 的单克隆 HEK293 细胞中的 hKCa1.1 电流。
NS 11021 (5 或 50 μM) 在青蛙腓肠肌中对静息膜电位 (RMP) 没有影响,同时以剂量依赖的方式显著增加动作电位 (AP) 上升时间。NS 11021 完全逆转过氧化氢对骨骼肌纤维 AP 复极化阶段的有害影响。
NS 11021 (1 μM) 有效减轻大鼠肾近端肾小管上皮 (NRK) 细胞中 CS + RW (冷藏 (18 小时) 和复温 (2 小时)) 诱导的 mitoBK 通道损伤、线粒体呼吸功能障碍、去极化、超氧化物产生和细胞死亡。
