产品描述 | Favipiravir is a potent and selective RNA-dependent RNA polymerase inhibitor for the treatment of influenza virus infections. |
靶点活性 | RdRP:341 nM. |
体外活性 | 方法:将RAW 264.7细胞中,使用T-705稀释系列(3.13-200 lg/mL),以0,001的MOI用MNV感染。采用MTS CPE还原法测定T-705在MNV/RAW 264.7细胞系中的抗病毒活性孵育3天后,即在感染的未处理细胞中观察到完全的CPE,收集细胞培养上清液,通过定量RT-PCR (qRT-PCR)定量检测病毒RNA载量。 结果:T-705 以剂量依赖的方式抑制 MNV 诱导的 CPE(EC50:39 ± 4 lg/mL [250 ± 11 lM])和细胞培养中的 MNV RNA 合成(EC50:19 ± 6 lg/mL [124 ± 42 lM])。[2] |
体内活性 | 方法:当Favipiravir (T-705)使用剂量为1-100mg/kg,并在感染致死剂量的流感病毒 A/Victoria/3/75(H3N2)、A/Osaka/5/70(H3N2) 或 A/Duck/MN/1525/81(H5N1) 的小鼠中每天口服 2 或 4 次,持续 5 天时,观察小鼠的生存率。 结果:与安慰剂相比,在Favipiravir (T-705)在30 mg/kg/天或更高的剂量下显示出更高的生存率,该药物还以33mg/kg/天或更高的剂量对A/Duck/MN/1525/81(H5N1)病毒提供了显着的保护。[1] 方法:在I型干扰素受体敲除(IFNAR −/−)小鼠中,在致命的 SFTSV 感染后的第1-5天内,以120mg / kg /天或200mg / kg /天的速度给予Favipiravir (T-705),并持续5天,观察小鼠的生长状态。 结果:当在感染后 3 天和 4 天内开始治疗时,所有剂量为 120 mg/kg/天或 200 mg/kg/天的法匹拉韦治疗的小鼠分别从致命的 SFTSV 感染中存活下来。[3] |
细胞实验 | The cytotoxicity of T-705 is evaluated by an assay with XTT. XTT is converted to aqueous formazan by an enzyme in MDCK cells, Vero cells, HEL cells, A549 cells, HeLa cells, and HEp-2 cells. The compounds are diluted to the appropriate concentrations (volume, 100 μl) with test medium (EMEM containing 10% FCS) in 96-well culture plates in which each well contains a concentration of 2 × 103 cells/100 μL. The test plates are incubated for 3 days at 37°C in 100% humidity and 5% CO2. After 3 days, 50 μl of the XTT reagent (1 mg/ml in FCS-free EMEM containing 5 mM phenazine methosulfate) is added, and the reaction product is assayed by measurement of the absorbance at 450 nm with a microplate reader. Cytotoxicity is expressed as the 50% cell-inhibitory concentration (CC50).(Only for Reference) |
