SphK
Sphingosine kinase
Sphingosine kinase (SphK1 and SphK2) is a lipid enzyme that catalyses the phosphorylation of sphingosine to form sphingosine 1-phosphate (S1P). Two isoforms of SphK are found in mammalian organisms, SphK1 and SphK2. SphK1 is found primarily in the cytoplasm and the plasma membrane of erythrocyte, endothelial and mast cells. SphK2 is larger and localized to the endoplasmic reticulum, nucleus, and mitochondria.
S1P binds to five different plasma membrane sphingosine 1-phosphate receptors (S1P1-5) and can regulate intracellular target proteins. S1P has a wide range of biological functions including promotion of cellular proliferation and survival, immune cell trafficking, stimulation of angiogenesis, and regulation of vascular integrity. Accumulation of S1P has been linked to the development/progression of cancer and various other diseases including, but not limited to, asthma, inflammatory bowel disease, rheumatoid arthritis, and diabetic nephropathy. Thus, the biosynthetic route to S1P is a logical target for drug discovery. SphK1 and SphK2 isozymes are also recognized therapeutic targets.

SLM6031434 hydrochloride
0 ImagesSLM6031434 hydrochloride is the hydrochloride salt form of SLM6031434 (HY-120268). 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).

Peretinoin (Standard)
0 ImagesSynonyms: NIK333 (Standard)Peretinoin (Standard) is the analytical standard of Peretinoin. This product is intended for research and analytical applications. Peretinoin is an oral acyclic retinoid with a vitamin A-like structure that targets retinoid nuclear receptors such as retinoid X receptor (RXR) and retinoic acid receptor (RAR). Peretinoin reduces the mRNA level of sphingosine kinase 1 (SPHK1) in vitro by downregulating a transcription factor, Sp1[1]. Peretinoin prevents the progression of non-alcoholic steatohepatitis (NASH) and the development of hepatocellular carcinoma (HCC) through activating the autophagy pathway by increased Atg16L1 expression[2]. Peretinoin inhibits HCV RNA amplification and virus release by altering lipid metabolism with a EC50 of 9 μM[3].
