SLM6031434 (hydrochloride)

SLM6031434 is an inhibitor of sphingosine kinase 2 (SPHK2) (Ki = 0.4 µM for the recombinant mouse enzyme). It is selective for SPHK2 over SPHK1 (Kis = >20 µM). It decreases sphingosine-1-phosphate (S1P, Cay-62570) and increases sphingosine levels in U937 monocytic leukemia cells in a concentration-dependent manner. SLM6031434 (5 mg/kg) reduces blood S1P levels in Sphk1-/-, but not Sphk2-/-, mice. SLM6031434 also increases blood S1P levels in wild-type mice and rats.Formal Name: (2S)-2-[3-[4-(octyloxy)-3-(trifluoromethyl)phenyl]-1,2,4-oxadiazol-5-yl]-1-pyrrolidinecarboximidamide, monohydrochloride.
