Discovery of Potent 3,5-Diphenyl-1,2,4-oxadiazole Sphingosine-1-phosphate-1 (S1P1) Receptor Agonists with Exceptional Selectivity against S1P2 and S1P3
摘要:
A class of 3,5-diphenyl-1,2,4-oxadiazole based compounds have been identified as potent sphingosine-1-phosphate-1 (S1P(1)) receptor agonists with minimal affinity for the S1P(2) and S1P3 receptor subtypes. Analogue 26 (S1P(1) IC50 = 0.6 nM) has an excellent pharmacokinetics profile in the rat and dog and is efficacious in a rat skin transplant model, indicating that S1P(3) receptor agonism is not a component of inummosuppressive efficacy.

The present invention is directed to an improved process for synthesizing azetidine-3-carboxylic acid, comprising triflating diethylbis(hydroxymethyl)malonate followed by azetidine ring-formation by intramolecular cyclization using an amine, decarboxylation to give the mono acid azetidine and hydrogenation to give the title compound. Azetidine-3-carboxylic acid is useful as an intermediate for making certain S1P?1#191/Edg1 receptor agonists, which are immunosupressive agents.
