In Vivo

Umifenovir (25 and 45 mg/ml; p.o.) shows a survival benefit to mice suffering from influenza infection[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: BALB/c mice (6–8 weeks old), mice were intranasally (i.n.) inoculated with 2 times the 50% mouse lethal dose (MLD50) of A/ Guangdong/GIRD07/09 (H1N1) (104.5TCID50/mL) in a volume of 20mL[3].
Dosage: 1.25 mg/mL (25 mg/kg/day) and 2.25 mg/mL (45 mg/kg/day) in a total volume of 500mL at one day pre-infection and 3 days post-infection (dpi)
Administration: Oral administration
Result: Increased the survival rate, inhibited the decrease of body weight at 45 mg/mL and inhibited the increase of mice lung index at 25 mg/mL and 45 mg/mL comparing to virus group.

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.
