Abstrakt: The action of compounds with general formula (formula: see text) on the frog heart ventricle, cat blood pressure, guinea pig ileum and frog rectus abdominis was studied. With dioxolane radicals (type F-2268) a strong muscarinomimetic action on the cat arterial blood pressure and guinea pig ileum was observed, with maximum marked action at n = 10, which was more pronounced at an even than at odd number of methylene groups. On the frog heart the compounds with an odd number of "n" elicited an atropine-like action. The compounds with pentyl radicals produced no effect on blood pressure and a weak cholinolytic effect on the frog heart. On the ileum they exhibited a cholinomimetic effect. All compounds studied acted as noncompetitive cholinolytics on the frog rectus.
