法匹拉韋細(xì)胞實驗
Cell lines           MDCK cells, Vero cells, HEL cells, A549 cells, HeLa cells, and HEp-2 cells
Preparation    method 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).
Concentrations 1000 μg/mL
Incubation time 3 d



法匹拉韋動物實驗

Animal models Mice infected with influenza virus A/PR/8/34
Formulation 0.5% methylcellulose
Dosages 200 mg/kg/day
Administration p.o.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

IntroductionFavipiravir(259793-96-9)Favipiraviris triphosphate are initially approved for therapeutic use in resistant cases of influenza.7,9 The antiviral targets RNA-dependent RNA polymerase (RdRp) enzymes.
Application1潛在冠狀病毒抑制劑Experimental Unapproved Treatments for COVID-19,may be an alternative option for influenza strains that are resistant to neuramidase inhibitors.9,19
Application2法匹拉韋在人體內(nèi)通過與糖作用生成“SCHEMBL7215591”,之后在結(jié)合磷酸鹽生成法匹拉韋三磷酸形式產(chǎn)物,最終對病毒產(chǎn)生作用。
Application3Favipiravir has been investigated for the treatment of life-threatening pathogens such as Ebola virus, Lassa virus, and now COVID-19.10,14,15

法匹拉韋(CAS:259793-96-9,英文名:favipiravir)不僅可以抑制甲型和乙型流感病毒的復(fù)制,而且該藥在禽流感的治療中也有不錯的療效,并且可能是對神經(jīng)酰胺酶抑制劑有抗藥性的流感菌株的替代選擇。可以作為治療威脅生命的病原體,例如埃博拉病毒,拉沙病毒和現(xiàn)在的COVID-19
Favipiravir作為前藥起作用,并在細(xì)胞內(nèi)進(jìn)行核糖基化和磷酸化,成為活性的Favipiravir-RTP。Favipiravir-RTP結(jié)合并抑制RNA依賴性RNA聚合酶(RdRp),最終可以阻止病毒轉(zhuǎn)錄和復(fù)制。
與現(xiàn)有的流感抗病毒藥相比,favipiravir的作用機(jī)制是新穎的,主要能阻止病毒從細(xì)胞中進(jìn)入和退出。活性的favipiravir-RTP選擇性抑制RNA聚合酶并阻止病毒基因組的復(fù)制。目前有幾種假設(shè)favipiravir-RTP如何與RNA依賴性RNA聚合酶(RdRp)相互作用。一些研究表明,將favipiravir-RTP摻入新生的RNA鏈中時,它會阻止RNA鏈延長和病毒增殖。7研究還發(fā)現(xiàn), 嘌呤類似物可以降低favipiravir的抗病毒活性,表明favipiravir-RTP和嘌呤核苷之間存在RdRp結(jié)合競爭7。
盡管favipiravir最初是開發(fā)用于治療流感的,但預(yù)計RdRp催化域(favipiravir的主要靶標(biāo))與其他RNA病毒相似。這種保守的RdRp催化域有助于favipiravir的廣譜覆蓋。
transcription of virus RNA segments. The transcription of viral mRNAs occurs by a unique mechanism called cap-snatching. 5' methylated caps of cellular mRNAs are cleaved after 10-13 nucleotides by PA. In turn, these short capped RNAs are used as primers by PB1 for transcription of viral mRNAs. During virus replication, PB1 initiates RNA synthesis and copy vRNA into complementary RNA (cRNA) which in turn serves as a template for the production of more vRNAs.Favipiravir shows anti-influenza virus activities with IC50 ranged from 0.013 to 0.48 μg/ml for the influenza A viruses, from 0.039 to 0.089 μg/ml for the influenza B viruses, and from 0.030 to 0.057 μg/ml for the influenza C viruses. In mammalian cell lines (MDCK cells, Vero cells, HEL cells, A549 cells, HeLa cells, and HEp-2 cells), Favipiravir shows no cytotoxicity at concentrations up to 1,000 μg/ml. In MDCK cells inoculated with seasonal influenza A (H1N1) viruses, Favipiravir induces lethal mutagenesis.

危險性
危險性警示 Based on single-dose toxicity studies, the lethal dose for oral and intravenous favipiravir in mice is estimated to be >2000 mg/kg.18 In rats, the lethal dose for oral administration is >2000 mg/kg, while the lethal dose in dogs and monkeys is >1000 mg/kg.18 Symptoms of overdose appear to include but are not limited to reduced body weight, vomiting, and decreased locomotor activity.18

備注 NA
In repeat-dose toxicity studies involving dogs, rats, and monkeys, notable findings after administration of oral favipiravir included: adverse effects on hematopoietic tissues such as decreased red blood cell (RBC) production, and increases in liver function parameters such as aspartate aminotransferase (AST), alkaline phosphatase (ALP), alanine aminotransferase (ALT) and total bilirubin, and increased vacuolization in hepatocytes.18 Testis toxicity was also noted.18 Favipiravir is known to be teratogenic; therefore, administration of favipiravir should be avoided in women if pregnancy is confirmed or suspected.7,16 Toxicity information regarding favipiravir in humans is not readily available.
