Syncytial Virus Inhibitor-1 is a potent and orally bioavailable inhibitor of respiratory syncytial virus (RSV) fusion(EC50s of 0.002 μM, 0.004 μM, and 0.002 μM for RSV Long, RSV A2, and RSV B strains, respectively).
RSVfusion protein IN-1 是一种口服活性RSV融合前F蛋白抑制剂,对RSV的IC50为0.10 nM。它能够与融合前F蛋白形成稳定的氢键和π-π堆积相互作用,从而阻断病毒的融合与入侵。此外,RSVfusion protein IN-1 可以抑制上皮细胞中RSVF蛋白的表达,并降低RSV感染小鼠模型肺部的病毒载量。该化合物适用于研究呼吸道合胞病毒(RSV)感染。
GS-441524tris-isobutyryl ester is a prodrug form of the antiviral nucleoside analog and remdesivir metabolite GS-441524 .1It reduces the cytopathic effect of respiratory syncytial virus (RSV) in infected HEp-2 cells with an EC50value of 0.26 μM.
