N. Hamanaka et al., MOLECULAR DESIGN OF NOVEL PGI(2) AGONISTS WITHOUT PG SKELETON .3., Bioorganic & medicinal chemistry letters, 5(10), 1995, pp. 1077-1082
Several ether, oxime, and amide derivatives related to 1 and 3 were sy
nthesized and tested as PGI(2) agonists. The results reveal the import
ance of the orientation between carboxylic acid and terminal diphenyl
groups in order to obtain high affinity interaction with PGI(2) recept
ors.
