Biological Activity

Description Baloxavir marboxil, a cap-endonuclease inhibitor, is an antiviral drug.
In vivo

Single-dose oral baloxavir marboxil is well tolerated, had a favorable safety profile, and has favorable pharmacokinetic characteristics, including a long half-life, supporting single oral dosing. In nonclinical studies, baloxavir marboxil is a prodrug and is converted to an active form, baloxavir acid, by hydrolysis. After single oral administration in rats and monkeys, plasma concentrations of baloxavir marboxil are below the lower limit of quantification (LLOQ) at all sampling points, and area under the plasma concentration-time curve of baloxavir acid increased dose proportionally. The major excretion route of radioactivity is via fecal excretion, whereas urinary excretion was low in rats and monkeys[3]. Baloxavir marboxil has shown therapeutic activity in preclinical models of influenza A and B virus infections, including strains resistant to current antiviral agents. In murine models of seasonal influenza and avian influenza A(H5N1) or A(H7N9), orally administered baloxavir is associated with rapid reductions in pulmonary viral loads and decreased mortality[1].

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
