Sphingosine 1-phosphate (S1P) is the endogenous ligand for the sphingosine 1-phosphate receptors (S1P1-5) and evokes a variety of cellular responses through their stimulation. The interaction of S1P with the S1P receptors plays a fundamental physiological role in a number of processes including vascular development and stabilization, lymphocyte migration, and proliferation. Agonism of S1P1, in particular, has been shown to play a significant role in lymphocyte trafficking from the thymus and secondary lymphoid organs, resulting in immunosuppression. This article will detail the discovery and SAR of a potent and selective series of isoxazole based full agonists of S1P1. Isoxazole 6d demonstrated impressive efficacy when administered orally in a rat model of arthritis and in a mouse experimental autoimmune encephalomyelitis (EAE) model of multiple sclerosis.

Disclosed are compounds of Formula (I) [INSERT CHEMICAL STRUCTURE HERE] (I) or pharmaceutically acceptable salts thereof, wherein Q is [INSERT CHEMICAL STRUCTURE HERE] or [INSERT CHEMICAL STRUCTURE HERE]; R1 is alkyl or aryl, said aryl optionally substituted with one to five substituents independently selected from C1 to C6 alkyl, C1 to C4 haloalkyl, OR4, and/or halogen; and R2, R3, R4, and n are defined herein. Also disclosed are methods of using such compounds as selective agonists for G protein-coupled receptor S1P1, and pharmaceutical compositions comprising such compounds. These compounds are useful in treating, preventing, or slowing the progression of diseases or disorders in a variety of therapeutic areas, such as autoimmune diseases and vascular disease.

Z-4-Enoic acids partially isomerize to E-configurated products in the Kolbe electrolysis.The results from methyl and deuterium labelled carboxylic acids 2 and 16 support an isomerization via a reversible ring closure to cyclopropylcarbinyl radicals.The double bonds of Z-N-enoic acids with N>/= 5 fully retain their configuration in the Kolbe electrolysis; for N=6,7 cyclic products are formed to some extent, which is in accord with the reactivity of 5- and 6-alkenyl radicals.
