GtoPdb Ligand ID: 911

Abbreviated name: S1P
PDB Ligand
Compound class: Metabolite or derivative
Comment: Sphingosine 1-phosphate (S1P) is a zwitterionic lyso-phospholipid product of the sphingosine biosynthetic pathway. It is a result of the phosphorylation of sphingosine by two well characterised kinases, SPHK1 and SPHK2 (sphingosine kinase 1 and 2). SPHK1 is predominately extracellular and SPHK1 intracellular. Sphingosine itself is produced by the N-deacylation of ceramide by the enzyme ceramidase.

Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.

Target Comment
GPR3 Sphingosine 1-phosphate was reported to be an endogenous agonist [25], but this finding was not replicated in subsequent studies [29]. Reported to activate adenylyl cyclase constitutively through Gs [6]. Gene disruption results in premature ovarian ageing [13], reduced β-amyloid deposition [24] and hypersensitivity to thermal pain [20] in mice. First small molecule inverse agonist [11] and agonists identified [28].
GPR63 Sphingosine 1-phosphate and dioleoylphosphatidic acid have been reported to be low affinity agonists for GPR63 [16] but this finding was not replicated in an arrestin-based assay [29].
GPR12 Reports that sphingosine 1-phosphate is a ligand of GPR12 [7,25] have not been replicated in arrestin-based assays [23,29]. Gene disruption results in dyslipidemia and obesity [2].
GPR6 An initial report that sphingosine 1-phosphate (S1P) was a high-affinity ligand (EC50 value of 39nM) [8,25] was not repeated in arrestin-based assays [23,29]. Reported to activate adenylyl cyclase constitutively through Gs and to be located intracellularly [18]. GPR6-deficient mice showed reduced striatal cyclic AMP production in vitro and selected alterations in instrumental conditioning in vivo. [14].
