  描述：

  methyl 4-[1-tert-butoxycarbonyl-(5R)-methoxymethyl-(2S)-pyrrolidinylmethoxy]cyclohexanecarboxylate 在 sodium methylate 、 三甲基硅烷化重氮甲烷 作用下， 以 甲醇 、 苯 为溶剂， 反应 23.0h， 生成 methyl trans-4-[1-tert-butoxycarbonyl-(5R)-methoxymethyl-(2S)-pyrrolidinylmethoxy]cyclohexanecarboxylate

  名称：

  A novel, potent, and orally active VLA-4 antagonist with good aqueous solubility: trans-4-[1-[[2-(5-Fluoro-2-methylphenylamino)-7-fluoro-6-benzoxazolyl]acetyl]-(5S)-[methoxy(methyl)amino]methyl-(2S)-pyrrolidinylmethoxy]cyclohexanecarboxylic acid

  摘要：

  We have carried out the optimization of substituents at the C-3 or the C-5 position on the pyrrolidine ring of VLA-4 antagonist 3 with 2-(phenylamino)-7-fluorobenzoxazolyl moiety for the purpose of improving in vivo efficacy while maintaining good aqueous solubility. As a result, we successfully increased in vitro activity in the presence of 3% human serum albumin and achieved an exquisite lipophilic and hydrophilic balance of compounds suitable for oral administrative regimen. The modification resulted in the identification of zwitterionic compound 7n with (5S)-[methoxy(methyl) amino] methylpyrrolidine, which significantly alleviated bronchial hyper-responsiveness to acetylcholine chloride at 12.5 mg/kg, p.o. in a murine asthma model and showed favorable aqueous solubility (JP1, 89 mu g/mL; JP2, 462 mu g/mL). Furthermore, this compound showed good oral bioavailability (F = 54%) in monkeys. (C) 2012 Elsevier Ltd. All rights reserved.
