    生物活性

    Oseltamivir acid (GS 4071), the active metabolite of Oseltamivir phosphate, is an orally bioavailable, potent and selective inhibitor of influenza virus neuraminidase (IC50=2 nM) with activity against both influenza A and B viruses[1][2].

    IC50 & Target

    IC50: 2 nM (influenza virus neuraminidase)

    体外研究
    (In Vitro)

    Oseltamivir acid 在体外和体内抑制病毒复制。B 型和 A/H1N1 型流感病毒似乎对奥司他韦敏感 (平均 B IC50 值:13 nM;平均 H1N1 IC50 值:1.34 nM),而 A/H1N2 和 A/H3N2 病毒对奥司他韦更敏感 (平均 H3N2 IC50 值:0.67 nM;平均 H1N2 IC50 值:0.9 nM)[3]
    在甲型流感病毒的神经氨酸酶抑制试验中,RWJ-270201 的 IC50 (约 0.34 nM) 与 Oseltamivir acid (0.45 nM) 相当。B 病毒分离株,RWJ-270201 (1.36 nM) 的 IC50 与 Zanamivir (2.7 nM) 相当,低于 Oseltamivir carboxylate (8.5 nM)[4]

    体内研究
    (In Vivo)

    Oseltamivir acid (0.1、1 或 10 mg/kg/天,每日两次,口服强饲法) 对 Vietnam/1203/04 (VN1203/04) 病毒产生剂量依赖性抗病毒作用。10 mg/kg/天的 5 天方案可保护 50% 的小鼠;该处理组的死亡是延迟的,表明处理完成后残留病毒的复制。1 和 10 mg/kg/天的剂量显著降低了器官中的病毒滴度,并分别提供了 60% 和 80% 的存活率[5]

    Animal Administration
    [3][4]

    Mice[3]
    Female 6-week-old BALB/c mice are anesthetized with isofluorane and intranasally inoculated with 50 μL of 10-fold serial dilutions of VN1203/04 virus in PBS. The mouse lethal dose (MLD50) is calculated after a 16-day observation period. Oseltamivir is administered by oral gavage twice daily for 5 or 8 days to groups of 10 mice at dosages of 0.1, 1, and 10 mg/kg/day. Control (infected but untreated) mice received sterile PBS (placebo) on the same schedule. Four hours after the first dose of Oseltamivir, the mice are inoculated intranasally with 5 MLD50 of VN1203/04 virus in 50 μL of PBS. Survival and weight change are observed for 24 days. Virus titers in the mouse organs are determined on days 3, 6, and 9 after inoculation. Three mice from each experimental and placebo group are killed, and the lungs and brains are removed. The organs are homogenized and suspended in 1 mL of PBS. The cellular debris is cleared by centrifugation at 2000 g for 5 min. The limit of virus detection is 0.75 log10 EID50. For calculation of the mean, samples with a virus titer <0.75 log10 EID50/mL are assigned a value of 0. Virus titers in each organ are calculated by use of the method of Reed and Muench and are expressed as mean log10 EID50/mL±SE.
    Rats[4]
    Several studies are performed to characterize the pharmacokinetics of Oseltamivir and OC in the plasma, cerebrospinal fluid (CSF), and brain of Sprague-Dawley rats following single-dose bolus administration of Oseltamivir (intravenous [i.v.] and oral) and OC (i.v.). In the i.v. studies, nonfasted adult rats (two groups of 35 animals for each test substance) received a dose of 30 mg/kg body weight of either Oseltamivir or Oseltamivir carboxylate (OC) in aqueous solution with sodium chloride (0.9%; pH 4.0) via slow injection into the tail vein over 20 to 30 s. In both i.v. studies, pharmacokinetic sampling took place at 5 min and at 0.25, 0.5, 1, 2, 4, and 8 h postdose (four or five rats/time point).

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
