Biological Activity

Description Crenigacestat (LY3039478) is an oral Notch and gamma-secretase inhibitor with IC50 of 0.41 nM for Notch.
Targets
Notch [1]
~1 nM
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].

Protocol (from reference)

Cell Assay:

[4]
  • Cell lines

    K07074 cells

  • Concentrations

    100 nM

  • Incubation Time

    24, 48, 72, 96 h

  • Method

    K07074 cells were plated to 24-well plates at 105 cell/well. Viability of cells was assessed in quadruplicates at indicated timepoints using the CellTiter-Glo luminescent cell viability assay. To study the effect of the small molecular compounds on K07074 cell growth the compounds or DMSO were added to the growth media 24 h after seeding. The cells were incubated with inhibitors and DMSO as indicated. Cell viability was assessed as described above. Each experiment was carried out in triplicate and at least 3 independent experiments were performed.
Animal Study:

[3]
  • Animal Models

    Mice

  • Dosages

    8 mg/kg

  • Administration

    oral gavage
