|Description||Savolitinib (volitinib, AZD6094, HMPL-504) is a novel, potent, and selective MET inhibitor currently in clinical development in various indications, including PRCC. The IC50 values of this compound for c-Met and p-Met are 5 nM and 3 nM, respectively. It shows exquisite selectivity for c-Met over 274 kinase.|
Volitinib has exquisite kinase selectivity and excellent potency. Volitinib displays a highly selective profile across a gastric cell line panel, potently inhibiting cell growth only in those lines with dysregulated cMET (EC50 values 0.6 nM/L-12.5 nM/L). Volitinib has high membrane permeability without efflux transport across Caco-2 cell monolayer and exhibits negligible P-gp inhibition (IC50 > 17 μM). Volitinib shows no significant reversible or mechanism-based CYP inhibition in human liver microsomes, and no induction of CYP1A2 and CYP3A4 in human hepatocytes.
|In vivo||In a mouse pharmacokinetic study (male ICR mice), the clearance of the compound is 4.28 L/(h·kg) and the half-time is 1.7 h. Despite its moderate oral bioavailability (F = 27.2%), the overall plasma exposure is much higher. Volitinib demonstrates dose-dependent tumor growth inhibition in a U87MG subcutaneous xenograft model. Its treatment leads to pharmacodynamic modulation of c-MET signaling and potent tumor stasis in 3/3 cMET-dysregulated gastric cancer patient-derived tumor xenograft models, but has negligible activity in a gastric cancer control model. Volitinib has moderate plasma protein binding rate (60%∼70% in rat, dog, and human; 40% in mouse; 80% in monkey) and exhibits wide distribution to different organs in rat, with high exposures in liver and kidney, very low in brain, spinal cord and testis compared to the plasma level. In PK studies in mouse, rat and dog, Volitinib shows the rapid oral absorption (Tmax<2.5 h) with high exposures and the acceptable bioavailability at 27.2%, 42.6% and 86.3%, respectively. The in vivo clearance (CL) is 11.0, 11.8 and 3.5 mL/min/kg in mouse, rat and dog, respectively, revealing a low extraction ratio. The volume of distribution in steady state (Vss) is 0.4, 1.4 and 1.4 L/kg in those species, respectively, indicating a moderate to low distribution pattern. Volitinib also displays linear pharmacokinetics (PK) in the dose ranges of 1 to 25 mg/kg in rat and 2 to 10 mg/kg in dog. Food hardly affects its PK profile in dog. In contrast, volitinib in monkey shows a notably high extraction ratio (CL=17.2 mL/min/kg) consistent with the in vitro metabolism result. Considering the rapid absorption of volitinib (Tmax=1.9 h) and moderately low distribution (Vss=0.7 L/kg), the poor oral bioavailability (1.9%) of volitinib in monkey is considered to be the result of excessive first-pass extraction. Overall, volitinib exhibits favorable preclinical PK/ADME properties.|

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
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).
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.
