Biological Activity

Description CYM-5442 is a potent and selective S1P1 agonist with EC50 of 1.35 nM.
In vitro

CYM-5442 is a chemically optimized version of an original hit (CYM-5181). CYM-5442 interacts with S1P1 in a binding pocket separate from key S1P1 residues Arg120 and Glu121 essential for high-affinity S1P binding and receptor activation. [1]

In vivo CYM-5442 is a full agonist for induction and maintenance of S1P1-dependent blood lymphopenia, decreasing B lymphocytes by 65% and T lymphocytes by 85% of vehicle. Induction of CYM-5442 lymphopenia is dose- and time-dependent, requiring serum concentrations in the 50 nM range. In addition, lymphopenia induced by CYM-5442 is reversed by W146 administration or upon pharmacokinetic agonist clearance. Pharmacokinetics in mice also indicates that CYM-5442 partitions significantly in central nervous tissue. [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 MSDS / 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 MSDS / 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.
