产品描述 | Vernakalant Hydrochloride (RSD1235 hydrochloride) is a mixed voltage- and frequency-dependent Na+ and atria-preferred K+ channel blocker. |
靶点活性 | Kv1.5 channel (T479A):1.63±0.09 μM, I508F:0.61±0.03 μM, Kv1.5 channel (WT):13.35±0.93 μM |
体外活性 | Block of Kv1.5 by Vernakalant Hydrochloride is mediated after channel activation because Vernakalant causes a relatively rapid onset of a block of channel current upon depolarization but little evidence of resting or “tonic” block of the channel. The most important effect is the reduction in potency for Vernakalant centered at I502A, which had an IC50 of 329±19 μM (n=4-10), compared with a control IC50 of 13.4±0.9 μM (n=5-23), which is a 25-fold decrease in potency. V505A, I508A, T480A, and C500A showed lesser reductions in potency on Kv1.5, of between 3- and 4-fold. IC50 for block by Vernakalant of wild-type and mutant Kv1.5 channels Fractional block is 13.35±0.93 μM, 0.61±0.03 μM, and 1.63±0.09 μM for Kv1.5 channels, Kv1.5 channelI508F, Kv1.5 channelT479A, respectively [1]. |

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。
