BMS-935177 Chemical Structure

Molecular Weight(MW): 502.56

BMS-935177 is a potent, reversible Bruton's Tyrosine Kinase (BTK) inhibitor with an IC50 value of 2.8 nM and demonstrates good kinase selectivity. It is more potent against BTK than other kinase, including the other Tec family kinases (TEC, BMX, ITK, and TXK) over which the compound is between 5- and 67-fold selective.

In vitro

BMS-935177 shows greater than 50-fold selectivity over the SRC family of kinases, including 1100-fold selectivity over SRC itself. Other kinases inhibited with a potency less than 150 nM (50-fold selectivity) included TRKA, HER4, TRKB, and RET. It inhibits calcium flux in human Ramos B cells (IC50 = 27 nM) and inhibits CD69 surface expression in peripheral B cells stimulated with anti-IgM and anti-IgG. However, BMS-935177 has no effect on CD69 surface expression in B cells stimulated through the CD40 receptor with CD40 ligand. Against IgG-containing immune complex-driven low affinity activating Fcγ receptor (FcγRIIa and FcγRIII) end points in peripheral blood mononuclear cells (PBMCs), BMS-935177 effectively inhibited TNFα production with an IC50 value of 14 nM[1].

In vivo Plasma protein binding for BMS-935177 is high for all species, with less than 1% free for human. It has excellent oral bioavailability in all preclinical species, from both suspension and solution dosing, despite its low aqueous solubility. The oral bioavailability for BMS-935177 with solution dosing ranges from 84% to 100% in rat, mouse, dog, and cynomolgus monkey, with low clearance in single intravenous (iv) infusion studies. When dosed at 2 mg/kg i.v. in mouse and rat, the T1/2 of BMS-935177 is 4 h and 5.1 h respectively[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 (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

*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 )

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.
