产品描述 | Presatovir (GS-5806) (GS-5806) is a novel, orally bioavailable RSV fusion inhibitor (mean EC50: 0.43 nM). |
靶点活性 | RSV:0.43 nM (EC50) |
体外活性 | Presatovir exhibits potent activity against a wide range of RSV A and B clinical isolates (mean EC50: 0.43 nM) [1]. GS-5806 inhibits pre to post triggered conformational changes of RSV F protein, suggesting a possible mechanism for antiviral activity [2]. |
体内活性 | In a cotton rat model of RSV infection, Presatovir demonstrates dose-dependent (0-30 mg/kg) antiviral efficacy. Oral bioavailability in preclinical species ranges from 46 to 100%, with penetration of the compound into the lung tissue demonstrated in Sprague-Dawley rats. Multidose oral treatment of Presatovir appears safe in adults, and in healthy human volunteers experimentally infected with RSV, a potent antiviral effect and reduction in disease severity are observed in the high dose group [1]. |
细胞实验 | GS-5806 is diluted in 100% DMSO. To conduct the cytopathic antiviral assay, 0.4 μL of 100×concentrated 3-fold serially diluted drug is added to 20 μL of cell culture medium in a 384-well plate. HEp-2 cells are then suspended in MEM plus 10% FBS at a density of 1×10^5 cells/mL, are infected in bulk with RSV A2 at a titer of approximately 1×10^4.5 tissue culture infectious doses/mL. Immediately following infection, 20 μL of RSV-infected cells are added to each well. The cells are then cultured for 4 days at 37 °C. Following this incubation, the cells are allowed to equilibrate to 25°C. The RSV-induced cytopathic effect is determined by adding 40 μL of Cell-Titer Glo viability reagent. Following a 10 min incubation at 25 °C, cell viability is determined [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。
