SLM6031434
目录号 : KCM12237 CAS No. : 1897379-33-7 纯度 : ≥98%
SLM6031434 is an inhibitor of sphingosine kinase 2 (SPHK2) (K = 0.4 μM for the recombinant mouse enzyme). It is selective for SPHK2 over SPHK1 (Ks = >20 μM). It decreases sphingosine-1-phosphate (S1P; ) 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.

生物活性

SLM6031434 is a highly selective sphingosine kinase 2 (SphK2) inhibitor with an IC50 value of 0.4 μM for SphK2. SLM6031434 exerts anti-fibrotic effects by increasing sphingosine accumulation and Smad7 expression. SLM6031434 demonstrates effective anti-fibrotic efficacy in a unilateral ureteral obstruction (UUO)-induced tubulointerstitial fibrosis mouse model. SLM6031434 can be used for the study of proteinuric kidney diseases or chronic kidney disease (CKD).

体外研究

SLM6031434 (3 μM, 16 h) reduces the expression of TGFβ-induced profibrotic markers (Col1, FN-1, CTGF) in primary mouse renal fibroblasts.
SLM6031434 (0.3-10 μM, 16 h) increased Smad7 protein expression in primary mouse renal fibroblasts in a dose-dependent manner.
SLM6031434 (1 μM, 20 h) significantly increased the ceramide levels in human podocytes.
SLM6031434 (1 μM, 24 h) upregulates the protein and mRNA expression of nephrin and Wilms tumor suppressor gene 1 (WT1) in wild-type human podocytes.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
