  Identification of N-acyl 4-(5-pyrimidine-2,4-dionyl)phenylalanine derivatives and their orally active prodrug esters as dual-acting alpha4–beta1 and alpha4–beta7 receptor antagonists

  摘要：

  N-Acyl 4-(5-pyrimidine-2,4-dionyl)phenylalanine derivatives of type 4 were designed to replace the 2,6-dichlorobenzoylamine portion of compound 1 in order to identify novel compounds with improved potency against alpha 4-integrins. Several derivatives were identified as very potent dual-acting alpha 4-integrin, alpha 4 beta 1 and alpha 4 beta 7 antagonists. Investigation of a limited number of prodrug esters led to the discovery of the ethyl ester prodrug 42, which demonstrated good intestinal fluid stability and good permeability. Despite low solubility, 42 gave acceptable blood levels of 30 when dosed orally in non-human primates. Additionally, 42 had an overall excellent profile and was selected for clinical trials. Investigation of N-acyl 4-(5-pyrimidine-2,4-dionyl)phenylalanine derivatives led to the discovery of several very potent dual-acting alpha 4-integrin antagonists. Ethyl ester prodrug 42 advanced to human clinical trials based on the excellent intestinal fluid stability, good permeability and superior efficacy in non-human primates. (C) 2012 Elsevier Ltd.
