Description: Crenigacestat, also known as LY3039478, is a orally bioavailable, novel small molecule Notch inhibitor with an IC50 of ~1nM in most of the tumor cell lines tested. LY3039478 potently inhibits mutant Notch receptor activity. In a xenograft tumor model, LY3039478 inhibited N1ICD cleavage and expression of Notch-regulated genes in the tumor microenvironment. LY3039478 is being investigated in Phase I.

Additional Information

LY3039478 is a Notch Inhibitor with potential anticancer activity. Notch signaling plays an important role during development and tissue homeostasis. Dysregulation of Notch signaling due to mutation or amplification, or overexpression of ligands and/or receptors is implicated in a number of malignancies. Therefore, inhibition of Notch signaling is a potential target for the development of cancer therapeutics
