  Synthesis and Biological Evaluation of Novel Pyridazinone-Based α₄ Integrin Receptor Antagonists

  摘要：

  A novel series of pyridazinone-functionalized phenylalanine analogues was prepared and evaluated for inhibition of cellular adhesion mediated by alpha(4)beta(1)/VCAM-1 and alpha(4)beta(7)/MAdCAM-1 interactions. Concise syntheses were developed and applied for exploration of structure-activity relationships pertaining to the pyridazinone ring as well as the N-acyl phenylalanine scaffold. Potent dual antagonists of alpha(4)beta(1) and alpha(4)beta(7) were generated from an amide subseries; antagonists selective for alpha(4)beta(7) were identified from urea and carbamate-based subseries. The pharmacokinetic properties of selected members of the series have been determined in rats and demonstrate that the use of ester prodrugs and alterations to the amide linkage can lead to improved oral bioavailability in this series. An alpha(4),beta(7)-selective member of the carbamate subseries (36c), upon oral admininstration, demonstrated in vivo efficacy in the mouse DSS colitis model.

  Structural modi. cation and cellular adhesion inhibition activities of pyridazinone-substituted phenylalanine amide alpha(4) integrin antagonists are described. Functionality requirements for the arylamide moiety and the carboxylic acid group were demonstrated. The study also revealed novel structure - activity relationships (SAR) for arylated pyridazinones. A correlation between bioavailability and permeability was also explored. A selected compound showed effectiveness in a mouse leukocytosis study. (c) 2008 Elsevier Ltd. All rights reserved.
