Selectivity and specificity of sphingosine 1-phosphate receptor ligands: "off-targets" or complex pharmacology?

Abstract:
A recent perspective published in Frontiers of Pharmacology by Salomone and Waeber (2011) discussed the selectivity and specificity of sphingosine 1-phosphate (S1P) receptor ligands. This perspective surveyed the use of various S1P receptor ligands and attempted to reconcile a number of inconsistencies in the predicted biological outcomes: these were interpreted as "off-target" effects. Therefore the perspective cautioned against the use of these S1P receptor ligands. Here we highlight the complex pharmacology of S1P receptors, which along with "inside-out" signaling might provide an alternative explanation for "off-target" effects.

Principles of Drug Action
Drugs can be agonists or antagonists. Like the endogenous ligands, agonists always bind and activate the target to produce a cellular response. Agonist binding induces a conformational change which in turn...
Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Drug-Receptor Interactions
Several parameters, such as the drug's affinity for its receptor and its efficacy, which is its ability to activate the receptor, determine the drug's effect on the tissue.
