产品描述 | Levobetaxolol hydrochloride ((S)-Betaxolol hydrochloride) is a beta-adrenergic receptor inhibitor (beta blocker), used to lower the pressure in the eye in treating conditions such as glaucoma. |
靶点活性 | β2-adrenoceptor:32.6 nM(Ki), β1-adrenoceptor:0.76 nM(Ki) |
体外活性 | Levobetaxolol potently antagonizes functional activities at cloned human β1 and β2 receptors, and also at guinea pig atrial β1, tracheal β2 and rat colonic β3 receptors with IC50s of 33.2 nM, 2970 nM and 709 nM, respectively. Levobetaxolol (Ki = 16.4 nM) is more potent than dextrobetaxolol (Ki = 2.97 μM) at inhibiting isoproterenol-induced cAMP production in human non-pigmented ciliary epithelial cells. [1] Levobetaxolol (topically applied) has been shown to reach the back of the eye in sufficient quantities to protect retinal ganglion cells from various types of insults. Levobetaxolol displaces [3H]-nitrendipine for L-type voltage-dependent calcium channel receptor with IC50 of 29.5 μM in rat cortex. Levobetaxolol reduces NMDA-stimulated 45Ca2+ influx by 47.3%. Levobetaxolol (topically applied) reduces the b-wave amplitude caused by ischaemia/reperfusion. [2] |
体内活性 | Levobetaxolol (150 mg/eye) is more potent than dextrobetaxolol, reducing intraocular pressure by 25.9% in conscious ocular hypertensive cynomolgus monkeys. [1] Levobetaxolol (20 mg/kg) significant protects retinal function and results in significantly thicker the RPE and outer nuclear layer in a photic-induced retinopathy rat model. Levobetaxolol (20 mg/kg) results in a 10-fold up-regulation of bFGF and a two-fold up-regulation of CNTF mRNA levels, trophic factors that have been shown to inhibit retinal degeneration in a number of species.

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
