Background

CB-1158 is an inhibitor of arginase I and II (IC₅₀s = 0.086 and 0.296 µM for the human enzymes, respectively).¹ It is selective for arginase I and II over neuronal nitric oxide synthase (nNOS), endothelial NOS (eNOS), and inducible NOS (iNOS; IC₅₀s = >50 µM for all). CB-1158 reverses inhibition of T cell proliferation induced by granulocytes in vitro (IC₅₀ = 0.204 µM). It reduces tumor growth in a CT26 murine colon cancer model when administered at a dose of 100 mg/kg twice per day.
