Description

General description

A cell-permeable thieno[2,3-d]pyrimidinedione compound that acts as a highly potent inhibitor of monocarboxylate transporter 1 (MCT1; K_i = 2.3 nM for lactate uptake in rat erythrocytes). Also shown to inhibit MCT2 when associated with basigin (IC₅₀ = 10 nM). Does not affect the activity of MCT4 even at higher concentration. Also shown to block MCT1 expressed in Xenopus oocytes Binds to MCT1 from the intracellular side involving transmembrane helices 7-10. Its inhibitory effect is significantly reduced with either F360Y or S364G mutations (~100 nM) and the inhibitory effect is lost with both sites are mutated (~5 µM). Displays high metabolic stability and low inhibition of CYP. Shown to block lactate transport and increase intracellular lactate levels in Raji Burkitt and MCF-7 cells and reduces their proliferation.
