AR-C141990 hydrochloride 

AR-C141990 hydrochloride is a potent lactate transporters (monocarboxylate transporters; MCTs) inhibitor with pK_i values of 7.6, 6.6 for MCT-1 and MCT-2, respectively^[1]. AR-C141990 hydrochloride has immunosuppressive properties and inhibits graft versus host response^[2].

pKi: 7.6 (MCT-1) and 6.6 (MCT-2)^[1]

AR-C141990 hydrochloride has no significant activity against MCT-3 (pIC₅₀<5) or MCT-4 (pIC₅₀<5)^[1].
AR-C141990 hydrochloride inhibits the uptake of [³H]HOCPCA in oocytes expressing MCT1 or 2 in a concentration-dependent manner with IC₅₀s of 0.21 µM and 2.32 µM, respectively^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

AR-C141990 hydrochloride (10 mg/kg; SC) with a parallel decline in plasma concentrations with a half-life around 20 minutes in male NMRI mice (18-22 g) ^[2].
Application of the corresponding plasma concentrations of AR-C141990 hydrochloride (0.3-90 mg/kg) results in a concentration-dependent decrease in the B/P of HOCPCA with an EC₅₀ of 860 ng/ml^[2].
AR-C141990 (100 mg/kg; s.c.) has a moderate prolongation of graft survival for 40 days in PVG rats that received DA cardiac transplants^[1].
