Biological Activity

Description Ro 61-8048 is a high-affinity kynurenine 3-hydroxylase (KMO) inhibitor with IC50 and Ki of 37 nM and 4.8 nM, respectively.

In vivo In gerbils and rats, Ro 61-8048 (30 mg/kg, p.o.) causes kynurenine 3-hydroxylase inhibition. [1] In models of focal or global brain ischemia, Ro 61-8048 (40 mg/kg, p.o.) reduce ischemic brain damage. [2] In a hamster model of paroxysmal dyskinesia, Ro 61-8048 (150 mg/kg i.p.) significantly reduces the severity of dystonia without leading to marked central side effects. [3] addition, prenatal inhibition of the kynurenine pathway by Ro 61-8048 leads to structural changes in the hippocampus of adult rat offspring. [4]

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.
