Replacement of the azetidine carboxylate of an S1P(1) agonist development candidate, AMG 369, with a range of acyclic head-groups led to the identification of a novel, S1P(3)-sparing S1P(1) agonist, ( )-2-amino -4-(3-fluoro-4-(5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridin-2-yl)phenyl)-2-methylbutanoic acid (8c), which possessed good in vivo efficacy and pharmacokinetic properties. A 0.3 mg/kg oral dose of 8c produced a statistically significant reduction in blood lymphocyte counts 24 h post-dosing in female Lewis rats. (C) 2011 Elsevier Ltd. All rights reserved.
