|Description||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.|

* 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 (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).
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.
