Nisoxetine is a potent and selective inhibitor of noradrenaline transporter (NET), with a Kd of 0.76 nM. Nisoxetine is an antidepressant and local anesthetic, it can block voltage-gated sodium channels[1][2][3].
Nisoxetine 抑制 [3H]Nisoxetine 与大鼠额叶皮层膜的结合，Ki 为 1.4±0.1 nM[2]。
Nisoxetine 抑制[3H]去甲肾上腺素摄取到大鼠额叶皮质突触体中，Ki 为 2.1±0.3 nM[2]。
Nisoxetine 抑制 Na+ 电流，膜电位为 -70 和 -100 mV 时的 IC50 分别为 1.6 和 28.6 µM[3]。
Nisoxetine (2.2 µM; a single intrathecal injection) shows 100, 100, and 100% of blockades in motor function, proprioception, and with duration of action of about 61, 96, and 236 min, respectively[3].
Nisoxetine (3,10, 30 mg/kg, i.p.) inhibits refeeding response (intake of standard chow) in rats[4].
| Animal Model: | Sprague-Dawley rats(290-340 g)[3] |
| Dosage: | 0.6, 1.2, 1.8, 2.2 µM |
| Administration: | A single intrathecal injection |
| Result: | Showed ED50s of 0.82, 0.75 and 0.70 µM in blocking motor function, proprioception, and nociception respectively. |
