Bumetanide (Ro 10-6338; PF 1593) 是一種高效的li尿劑,是 Na+-K+-Cl+ 協(xié)同轉運蛋白 (NKCC) 的阻斷劑。Bumetanide 是選擇性的 NKCC1 抑制劑,但對 NKCC2 也有抑制作用,對 hNKCC1A 和 hNKCC2A 作用的 IC50 值分別為 0.68 μM 和 4.0 μM。
生物活性
Bumetanide (Ro 10-6338; PF 1593), a highly potent loop diuretic, is a Na+-K+-Cl+ cotransporter (NKCC) blocker. Bumetanide is a selective NKCC1 inhibitor, but also inhibits NKCC2, with IC50s of 0.68 μM and 4.0 μM for hNKCC1A and hNKCC2A, respectively
IC50 & Target
IC50: 0.68 μM (hNKCC1A), 4.0 μM (hNKCC2A)[1]
體外研究(In Vitro)
Bumetanide has inhibitory effects for the two major human splice variants of NKCCs, hNKCC1A and hNKCC2A [1].
Bumetanide (0.03-100 μM; 5 minutes) inhibits the 86Rb+ uptake in NKCC1A-expressing oocytes in a dose-dependent manner[1].
Bumetanide inhibits NKCC2 isoform B in HEK-293 cells with an IC50 value of 0.54 μM
體內(nèi)研究(In Vivo)
Bumetanide (7.6-30.4 mg/kg; i.v.) attenuates the decrease in apparent diffusion coefficients (ADC) ratios for both cortex and striatum (by 40-67%), indicating reduced edema formation[3].
Bumetanide also reduces infarct size[3].
Bumetanide shows different half-lives of 21.4 min, 53.8 min and 137 min following 2 mg/kg, 8 mg/kg and 20 mg/kg intravenous injection, respectively, in rats
Animal Model: | Normotensive Sprague-Dawley rats (250-300 g)[3] |
Dosage: | 7.6 mg/kg, 15.2 mg/kg, 30.4 mg/kg |
Administration: | Intravenous injection |
Result: | Reduced the middle cerebral artery occlusion (MCAO)-induced decrease in ADC values in all four ipsilateral regions (L1-L4). |
Animal Model: | Male Sprague-Dawley rats (220-300 g)[4] |
Dosage: | 2 mg/kg, 8 mg/kg, 20 mg/kg (Pharmacokinetic Analysis) |
