| 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]. |

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 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.
