|Description||Onametostat (JNJ-64619178) is a PRMT5 inhibitor with high selectivity and potency (subnanomolar range, PRMT5-MEP-50 IC50=0.14 nM) under different in vitro and cellular conditions, paired with favorable pharmacokinetics and safety properties.|
JNJ-64619178 binds into the SAM binding pocket and reaches the substrate binding pocket to inhibit PRMT5/MEP50 function in a time-dependent manner. Broad cell line panel profiling of JNJ-64619178 reveals a wide range of sensitivity, which is indicative of a genomic dependency instead of a general cytotoxic on-target consequence of PRMT5 inhibition.
|In vivo||JNJ-64619178, dosed orally (10 mg/kg, every day), shows selective and efficient blockage of the methylation of SMD1/3 proteins, which are crucial components of the spliceosome and substrates of PRMT5/MEP50. JNJ-64619178 also demonstrates tumor regression in a biomarker-driven human small cell lung cancer xenograft model (NCI-H1048) and prolongs tumor growth inhibition after dosing cessation. In rodent and nonrodent toxicology studies, a tolerated dose of JNJ-64619178 has been identified, with the observed toxicity consistent with on-target activity. In summary, JNJ-64619178 has a favorable preclinical package that supports clinical testing in patients diagnosed with lung cancer and hematologic malignancies1.|

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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 SDS / 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 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.
