Novel substituted pteridine-derived inhibitors of monocarboxylate transporter 1 (MCT1), an emerging target for cancer therapy, are reported. The activity of these compounds as inhibitors of lactate transport was confirmed using a 14C-lactate transport assay, and their potency against MCT1-expressing human tumor cells was established using MTT assays. The four most potent compounds showed substantial anticancer activity (EC50 37–150 nM) vs MCT1-expressing human Raji lymphoma cells.
