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.
This invention provides an industrially useful process for producing 1,4-transcyclohexanecarboxylic acid derivative (1) which has excellent VLA-4 inhibitory action and safety, and an intermediate which is useful in such method. More particularly, this invention relates to a process for converting a compound of formula (I) into a compound of formula (VI) by the reaction scheme:
