Identification of LY3522348: A Highly Selective and Orally Efficacious Ketohexokinase Inhibitor.
J.Med.Chem., 66:15960-15976, 2023

PubMed Abstract: The identification of clinical candidate LY3522348 (compound ) is described. LY3522348 is a highly selective, oral dual inhibitor of human ketohexokinase isoforms C and A (hKHK-C, hKHK-A). Optimization began with highly efficient ()-2-(2-methylazetidin-1-yl)-6-(1-pyrazol-4-yl)-4-(trifluoromethyl)nicotinonitrile (). Efforts focused on developing absorption, distribution, metabolism, potency, and in vitro safety profiles to support oral QD dosing in patients. Structure-based design leveraged vectors for substitution of the pyrazole ring, which provided an opportunity to interact with several different proximal amino acid residues in the protein. LY3522348 displayed a robust pharmacodynamic response in a mouse model of fructose metabolism and was advanced into clinical trials.
