    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.

  • Accelerating Effect of Triazolyl and Related Heteroaryl Substituents on S<sub>N</sub>Ar Reactions: Evidence of Hydrogen-Bond Stabilized Transition States

    日期:2015.9.30
    accelerating effect of 1,2,3-triazolyl substituents on SNAr reactions has been investigated through systematic experiments and density functional theory calculations. The lone pair electrons of an ortho-triazolo substituent play a key role in lowering the activation energy for nucleophilic addition via formation of a preferential hydrogen bond with the amine nucleophile at the transition state for addition
