Asymmetric Synthesis of Conformationally Constrained Fingolimod Analogues—Discovery of an Orally Active Sphingosine 1-Phosphate Receptor Type-1 Agonist and Receptor Type-3 Antagonist
摘要:
Compound 1 (FTY720, Fingolimod) represents a new generation of immunosuppressant that modulates lymphocyte trafficking by interacting with the S1P(1) receptor. Compound 1 also provides a template molecule for studying the molecular biology of S1P receptors and related enzymes (kinases and phosphatases). In this study, two conformationally constrained analogues of 1 (3a and 3c) were asymmetrically synthesized in high optical purity. In vitro assessment documented that both analogues are Sphk2 substrates, their phosphorylated species are potent S1P(1) receptor agonists, and 3a-P is a potent SIP3 antagonist. After oral administration in mice, both compounds evoked lymphopenia, but their duration of action differed markedly.

The present invention is directed to novel, potent, and selective agents, which are agonists or antagonists of the one or more of the individual receptors of the S1P receptor family. The compounds of the invention are useful as therapeutics for treating medical conditions associated with agonism or antagonism of the individual receptors of the S1P receptor family.
