Background

LY345899 is an inhibitor of methylenetetrahydrofolate dehydrogenase 1 (MTHFD1) and MTHFD2 (IC₅₀s = 96 and 663 nM, respectively).¹ It decreases the NADPH-to-NADP⁺ (NADPH/NADP⁺) and reduced glutathione-to-oxidized glutathione (GSH/GSSG) ratios and increases the production of reactive oxygen species (ROS) in HCT116, SW620, and LoVo colorectal cancer cells when used at a concentration of 10 ?M.² LY345899 is cytotoxic to SW620 and LoVo cells, an effect that can be reversed by the antioxidant N-acetyl-L-cysteine . In vivo, LY345899 (10 mg/kg) reduces tumor growth in a patient-derived xenograft (PDX) mouse model of colorectal cancer.
