CAS No. : 210354-22-6
MCE 国际站:GW274150
产品活性:GW274150 是一种有效的,选择性的,口服活性的 NADPH 依赖型人一氧化氮合成酶 (iNOS) (Kd=40 nM) 和大鼠诱导型一氧化氮合酶 (iNOS) 抑制剂。GW274150 对人和大鼠的内皮一氧化氮合酶 (eNOS) 和神经元一氧化氮合酶 (nNOS) 均显示较低效力。GW274150 在急性肺损伤炎症模型中发挥保护作用。
研究领域:Immunology/Inflammation
作用靶点:NO Synthase
In Vitro: GW274150 inhibits intracellular iNOS in J774 cells in a time-dependent manner, reaching IC50 values of 0.2 μM.GW274150 is >260-fold and 219-fold selective for iNOS against eNOS and nNOS in rat tissues, respectively. And it displays >100-fold and >80-fold for human iNOS against human eNOS and nNOS, respectively.
In Vivo: GW274150 is a long-acting (5 h half‐life in rats) iNOS inhibitor and is able to inhibit LPS‐mediated increase in plasma NO2-, NO3- levels 14 h after single intraperitoneal dose (ED50=3 mg/kg).GW274150 (intraperitoneal injection; 2.5, 5, and 10 mg/kg; before carrageenan injection) reduces the degree of lung injury induced by carrageenan in a dose-related fashion. Oedema formation and PMNs infiltration in the pleural cavity are also significantly attenuated in a dose‐related manner in rats.GW274150 (oral adminstration; 30 mg/kg; twice daily; 7 days) leads to significant neuroprotection, However, it displays a bell-shaped neuroprotective profile, being ineffective at high doses in 6-OHDA rat model of Parkinson disease (PD).
