ABSTRACT
Based on the promising results obtained by the clinical trial of Ariflo, further optimization of the spatial arrangement of the three pharmacophores (the carboxylic acid moiety, nitrile moiety and 3-cyclopentyloxy-4-methoxyphenyl moiety) in the structure of Ariflo 1 was attempted using a bicyclo[3 ?3 ?0]octane template with more stereochemical diversity than the cyclohexane template of Ariflo 1. Biological evaluation of the decyanated analogs and further optimization of the cyclopentyloxy moiety of 2a-b were also performed. Among the compounds tested, 2a, 7a-b and 12a were found to be orally active and were estimated to have therapeutic potential based on cross-species and same-species comparisons. The structure-activity relationships (SARs) of these compounds were investigated and pharmacokinetic data for 2a and 7b were also obtained by single-dose studies in rats.
