Pimodivir

產品活性：Pimodivir (VX-787) 是一種可口服的甲型流感病毒聚合酶抑制劑，通過抑制PB2亞基起作用。

研究領域：Anti-infection

作用靶點：Influenza Virus

In Vitro: Pimodivir rescues macrophages from virus-mediated death at non-cytotoxic concentrations 24 hpi. The EC₅₀ value for Pimodivir are 8 and 12 nM for A(H1N1) and A(H3N2) strains, respectively, whereas the CC₅₀ values are >1 μM, giving selectivity indexes (SI) > 125 and > 83 for A(H1N1) and A(H3N2) strains, respectively. Pimodivir significantly attenuates the transcription of viral M1 RNA in macrophages, which are infected with A(H1N1) or A(H3N2) strains for 8 h. Pimodivir inhibits the transcription of viral but not cellular genes. Pimodivir allows some activation of IAV-mediated expression of several cellular genes, which are involved in tryptophan and nucleotide metabolism. Pimodivir possesses excellent anti-IAV but not immuno/metabolo-modulating effect. Pimodivir (VX-787) is very potent against influenza A strains, including pandemic 2009 H1N1 and avian H5N1. Pimodivir (VX-787) shows potent activity against all influenza A virus strains tested, with an EC₅₀ range of 0.13 to 3.2 nM. Pimodivir-selected PB2 variant viruses maintain susceptibility to neuraminidase inhibitors in vitro.

In Vivo: Pimodivir (2, 6, and 20 mg/kg/day, p.o.) and oseltamivir (20 mg/kg/day) completely prevent death in the H1N1pdm virus infection in mice. Pimodivir (20 mg/kg/day) is more effective than oseltamivir (20 mg/kg/day) in improving body weight and reducing the severity of lung infection. Moreover, Pimodivir (VX-787) shows * survival in a +48 h delay to treatment mouse influenza model at 10, 3 and 1 mpk (BID × 10 days) whereas the SOC, oseltamivir, provide no survival benefit in this model at 10 mpk. Pimodivir (VX-787; 1, 3, or 10 mg/kg, bid) provided complete survival, with a dose-dependent reduction in BW loss of the mice.
