Chemical structure

AR-C155858

Protocol

Cell experiment [1]:

Cell lines

Ras-transformed fibroblast CCL39 cells

Preparation method

The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months.

Reacting condition

100 nM

Applications

In Ras-transformed fibroblast CCL39 cells, AR-C155858 potently suppressed the uptake of lactic acid by inhibiting MCT1 and MCT2, which significantly decreased glycolysis.

Animal experiment [2]:

Animal models

Nude mice implanted with Ras-transformed CCL39 fibroblasts

Dosage form

30 mg/kg; s.c.; b.i.d., for 6 days

Applications

In nude mice implanted with Ras-transformed CCL39 fibroblasts that only expressed MCT1/2, AR-C155858 increased intracellular lactate pool, reduced glycolysis and growth in hypoxia, as well as inhibited tumor growth.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

AR-C155858 is a potent and selective inhibitor of monocarboxylate transporters MCT1 and MCT2 with Ki values of 2.3nM and less than 10 nM, respectively [1].
MCT is a monocarboxylate transporter family with 14 members. Among these transporters, MCT1 and MCT2 are worked for the uptake and efflux of lactic acid. As a selective inhibitor of MCT1 and MCT2, AR-C155858 can be used to probe MCTs’ roles in the metabolic studies. Besides that, AR-C155858 was found to have immunosuppressive activity and can inhibit the proliferation of T-lymphocytes. The binding site of MCT1 for AR-C155858 contains transmembrane helices 7-10 in C-terminal domain. The two residues Phe360 and Ser364 play important roles in the binding [1 and 2].
In rat erythrocytes in which the AE1 mediated lactate transport had been blocked, AR-C155858 inhibited endogenous MCT1 mediated L-lactate uptake dose-dependently. AR-C155858 showed to be a tight-binding non-competitive inhibitor with Ki value of 2.3±1.4 nM and Kcat value of 12.2±1.1 s-1.In Xenopus oocytes expressing MCT1, MCT2 or MCT4, AR-C155858 at concentration of 100 nM showed 100% inhibition of MCT1 mediated lactate uptake. For MCT2, AR-C155858 at 10 nM showed 70% inhibition. AR-C155858 had no significant effect against MCT4 even at concentration up to 10 μM. In addition, it has been found that the inhibition of MCTs caused by AR-C155858 can be affected by the co-expression of ancillary proteins. The presence of embigin reduced the sensitivity of MCT2 against AR-C155858’s inhibition. AR-C155858 potently suppressed the uptake of lactic acid in Ras-transformed fibroblast CCL39 cells via inhibiting MCT1 and MCT2 but no MCT4. The suppression subsequently resulted in significant decrease of glycolysis [1, 3 and 4].
In nude mice implanted with Ras-transformed CCL39 fibroblasts, the administration of AR-C155858 at dose of 30 mg/kg twice daily resulted in significant tumor growth suppression [4].
