Discovery of APD334: Design of a Clinical Stage Functional Antagonist of the Sphingosine-1-phosphate-1 Receptor
摘要:
APD334 was discovered as part of our internal effort to identify potent, centrally available, functional antagonists of the S1P(1) receptor for use as next generation therapeutics for treating multiple sclerosis (MS) and other autoimmune diseases. APD334 is a potent functional antagonist of S1P(1) and has a favorable PK/PD profile, producing robust lymphocyte lowering at relatively low plasma concentrations in several preclinical species. This new agent was efficacious in a mouse experimental autoimmune encephalomyelitis (EAE) model of MS and a rat collagen induced arthritis (CIA) model and was found to have appreciable central exposure.
To provide a novel compound which has S1P receptor agonistic activity, exhibits excellent immunosuppressing effect, gives less adverse side effects, and can be orally administered.
The invention provides a compound represented by general formula (I) (wherein A is a single bond, —O—, or —CH
