Abstract:
:Whereas the 2-propyl- and 2-butyl-5,6-(methylenedioxy)indene calcium antagonists reversed the spasmogenic action of several agonists including PGF2alpha and acetylcholine at 5 X 10(-5) to 10(-4) M on the rat ileum, the corresponding 5,6-dimethoxy analogues exhibited spasmogenic activity at higher concentration (10(-4)-10(-3) M) and exhibited neither spasmogenic nor spasmolytic activity at lower (10(-6)-10(-5) M) concentration. The results are compared to the methyl and 2-ethyl analogues. At 10(-4) M only the butyl analogue was capable of moderate antagonism of acetylcholine and at 10(-3) M all four analogues were capable of moderately antagonizing the actions of acetylcholine.
