  Identification of 4-[1-[3-chloro-4-[N’-(5-fluoro-2-methylphenyl)ureido]phenylacetyl]-(4S)-fluoro-(2S)-pyrrolidinylmethoxy]benzoic acid as a potent, orally active VLA-4 antagonist

  摘要：

  Optimization of benzoic acid derivatives by introducing substituents into the diphenyl urea moiety led to the identification of compound 201 as a potent VLA-4 antagonist. Compound 201 inhibited eosinophil infiltration into bronchial alveolar lavage fluid in a murine asthma model by oral dosing and its efficacy was comparable to anti-mouse alpha 4 antibody (R1-2). Furthermore, this compound significantly blocked bronchial hyper-responsiveness in the model. (c) 2008 Elsevier Ltd. All rights reserved.
