Ki: 2.3 nM (MCT1), 10 nM (MCT2) |
In Vitro | AR-C155858 (10 nM-100 nM) inhibits MCT1/MCT2 C-terminal chimaeras[1]. AR-C155858 inhibits MCT2, and the 70% inhibition seen at 10 nM is followed by a gradually increasing inhibition which can only be explained by a Ki value of significantly less than 10 nM. AR-C155858 inhibits MCT1 expressed in Xenopus oocytes in a time- and concentration-dependent manner[2]. |
Kinase Assay | MCT kinetic assays are performed by monitoring intracellular pH with H+-sensitive dye BCECF or by determining the uptake of l-[14C]lactate (7.4 MBq/mL). The uptake buffer containes 75 mM NaCl, 2 mM KCl, 0.82 mM MgCl2, 1 mM CaCl2 and 20 mM Tris/Hepes (pH 7.4). AR-C155858 inhibitor titrations are performed at pH 6 with oocytes preincubated for 45 min in a different uptake buffer (75 mM NaCl, 2 mM KCl, 0.82 mM MgCl2, 1 mM CaCl2 and 20 mM Mes, pH 6) containing the required concentration of AR-C155858 prior to measuring the uptake of l-[14C]lactate (0.5 mM). Unless stated otherwise, uptake is determined over 2.5 min for all MCT constructs except for MCT2trn with or without embigin and MCT2/1 with or without embigin, where 5 and 10 min are used respectively. |
Cell Assay | The erythrocytes (5% haematocrit) are pre-incubated for 1 h at room temperature (22°C) with or without AR-C155858 at the required concentration before assaying transport of l-lactate (10 mM) at 6°C. Initial rates of transport are calculated by first-order regression analysis of the time course of pH change and converted into nmol of H+/min by determining the pH change induced by small additions of standardized NaOH. |
