IACS-10759 Hydrochloride is a potent inhibitor of complex I of oxidative phosphorylation (OXPHOS). OXPHOS[1]
IACS-10759 inhibits the conversion of NADH to NAD+ in an immunoprecipitated complex I assay at low nM concentrations[1].
IACS-10759 is orally bioavailable with excellent physicochemical properties in preclinical species and achieves significant in vivo efficacy with daily oral dosing of 10-25 mg/kg. There is a >50 day extension of median survival in an orthotopic AML cell line xenograft and robust regression in DLBCL and GBM xenograft models[1].
