Based on the successful results in the clinical trial of Ariflo(TM), further optimization of the spatial arrangement of the three pharmacophores (carboxylic acid moiety, nitrile moiety and 3-cyclopentyl-4-methoxyphenyl moiety) in the structure of Ariflo 1 was attempted using a bicyclo[3(.)3(.)0]octane template instead of a cyclohexane template. As a result, 2a, 7a and 7b were found to be orally active and were predicted to have an improved therapeutic potential based on evaluation by cross-species and same-species comparisons. Structure-activity relationships (SARs) of these compounds are also discussed. (C) 2003 Elsevier Ltd. All rights reserved.
