| In vitro |
LY3039478 is a novel small molecule that is an exquisitely potent inhibitor of Notch-1 intracellular domain (N1ICD) cleavage with an IC50 of ∼1nM in most of the tumor cell lines tested. LY3039478 also potently inhibits mutant Notch receptor activity[2]. Treatment with a gamma secretase inhibitor, LY3039478, significantly inhibited the growth of 2 CCRCC(Clear cell renal cell carcinoma) cell lines in a concentration dependent manner. LY3039478 treatment also led to decreased expression of Myc and Cyclin A1, two genes that were part of the NOTCH driven proliferative signature in murine and human model systems. LY3039478 treatment also led to G0/G1 cell cycle arrest in CCRCC cells[3]. |

| In vivo | In mice, its oral bioavalability(%F) is 65%, clearance(CL)=41 mL/min/kg, VDss = 3.8 L/kg. In Rats, its oral bioavalability(%F) is 65%, CL=98 mL/min/kg, VDss=4.9 L/kg. In Dogs, its oral bioavalability (%F) is 67%, CL=3.8 mL/min/kg, VDss=1.4 L/kg[1]. In a xenograft tumor model, LY3039478 inhibited N1ICD cleavage and expression of Notch-regulated genes in the tumor microenvironment. The inhibition of Notch cleavage also resulted in the induction of apoptosis in a Notch-dependent xenograft model[2]. In immunodeficient NSG mice xenografted with 769-P CCRCC cells, LY3039478 treatment resulted in significantly increased survival and delayed tumor growth in independent cohorts of mice demonstrating in vivo efficacy in CCRCC[3]. |

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.
