7ACC2 is a carboxycoumarin inhibitor of monocarboxylate transporter 1 (MCT1) with an IC50 value of 10 nM for lactate uptake, an MCT1-dependent process, in SiHa human cervix carcinoma cells.1 It inhibits proliferation of SiHa cells in the presence of lactate in a dose-dependent manner but lacks cytotoxicity in the presence of glucose. 7ACC2 also inhibits the mitochondrial pyruvate carrier (MPC) in a concentration- and time-dependent manner in isolated tumor cell mitochondria.2 In vivo, 7ACC2 (3 mg/kg) increases intratumor lactate accumulation and decreases tumor size in an SiHa mouse xenograft model.
