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.
