| In vitro |
GSK583 possesses comparable binding affinity for RIP3 kinase as demonstrated by an in-house FP binding assay configured similarly to the RIP2 FP assay (RIP2 FP IC50 = 5 nM; RIP3 FP IC50 = 16 nM). Despite this potent biochemical activity against RIP3 kinase, GSK583 shows little or no inhibition of RIP3-dependent necroptotic cell death in a cellular assay up to 10 μM concentration. GSK583 potently and dose dependently inhibits MDP-stimulated tumor necrosis factor-alpha (TNFα) production with an IC50 = 8 nM in primary human monocytes. Following treatment with GSK583 at 1 μM, little inhibition of pro-inflammatory signaling is observed upon activation of Toll-like receptors (TLR2, TLR4, TLR7) or cytokine receptors (IL-1R, TNFR) but complete inhibition is observed upon activation of both NOD1 and NOD2 receptors, which signal in a RIP2-dependent manner. Although GSK583 has excellent kinase selectivity, it does inhibit both the hERG channel and Cyp3A4, which precludes it from further progression as a drug candidate[1]. |

| In vivo | GSK583 has low clearance, moderate volumes of distribution, and moderate oral bioavailability in both rat and mouse. Eventhough GSK583 would not produce a human phamacodynamic response within an acceptable dose range which precludes this molecule from further development as a drug candidate, the oral PK in rat and mouse provides sufficient systemic exposure for use as a preclinical in vivo tool molecule in an acute inflammation challenge model[1]. |

Bio Calculators
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)
*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
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 )
* 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.
