用途: NS-1619 is a selective large conductance Ca2+-activated K+-channel activator.IC50 value: Target: Ca2+-activated K+-channel activatorNS 1619 (3-100 microM) produced a concentration-dependent inhibition of spontaneous activity in rat portal vein characterized by a reduction in the amplitude and duration of the tension waves. This inhibition was slightly potentiated in the presence of either charybdotoxin (250 nM) or penitrem A (1 microM) [1]. NS-1619 induced concentration-dependent activation of BKCa channels with a calculated EC50 of 32 microM. The NS 1619-induced activity was dependent on the presence of free Ca2+ at the intracellular surface, but was not associated with a change in channel voltage sensitivity [2]. NS 1619 (50 microM) inhibited the noradrenaline-induced contraction. NS 1619 (10-100 microM) reduced the high K+-induced contractions in a noncompetitive manner [3]. Inhalation of a 12 μM and 100 μM NS1619 solution significantly reduced RV pressure without affecting systemic arterial pressure. Blood gas analyses demonstrated significantly reduced carbon dioxide and improved oxygenation in NS1619-treated animals pointing towards a considerable pulmonary shunt-reducing effect. In PASMC's, NS1619 (100 μM) significantly attenuated PASMC proliferation by a pathway independent of AKT and ERK1/2 activation [4]. 物理化学性质: CAS号:153587-01-0 常用中文名:1-(2-羟基-5-(三氟甲基)苯基)-5-(三氟甲基)-1H-苯并[d]咪唑-2(3h)-酮 常用英文名:NS-1619 分子式:C15H8F6N2O2 分子量:362.22700 密度:1.563g/cm3 沸点:N/A 熔点:234 °C(dec.) 闪点:N/A 储存条件:存放于惰性气体之中;避免空气 |
