In this study, twelve compounds having 9-aryl-3,4,6,7-tetrahydroacridine-1,8-(2H,5H,9H,10H)-dione structure were synthesized by reaction of 5-methyl-1,3-cyclohexanedione, the appropriate aromatic aldehydes, and ammonium acetate in methanol. The structures of the compounds were elucidated by infrared, H-1- and C-13-nuclear magnetic resonance spectroscopy (-NMR), mass spectroscopy, and elemental analysis. The maximum relaxant effects (E (max)) and pD2 values of the compounds 3a-l and pinacidil were tested on isolated strips of rabbit gastric fundus smooth muscle.
