摘要: The invention relates to xanthene-9-carboxylates of the formula ##STR1## wherein R.sub.1 and R.sub.3 may be the same or different and represent a lower alkyl group,n and m each are integers of 2 to 5, or pharmaceutically-effective salts thereof. The compounds according to the invention possess cholinolytic and bronchospasmolytic effects and are completely devoid of harmful side-effects. Thus these compounds can be used to great advantage in therapy.

摘要: The invention relates to new xanthene-9-carboxylates of the formula (I), ##STR1## wherein R.sub.1 and R.sub.3 are the same or different and each can represent a lower alkyl group,R.sub.2 is a lower alkyl group or a group of the formula (VI), ##STR2## WHEREIN M IS AN INTEGER OF 2 TO 5, OR R.sub.1 and R.sub.2 form, together with the adjacent nitrogen atom, a five- or six-membered heterocyclic group, and n and m each represent integers of 2 to 5, or salts thereof. These compounds possess cholinolytic and bronchospasmolytic effects and are completely devoid of harmful side-effects. Thus these compounds can be used to great advantage in therapy. The new compounds of the formula (I) or their salts can be prepared by reacting a diaminoalcohol of the formula (III), ##STR3## wherein R.sub.2 is lower alkyl or a group of formula -(CH.sub.2).sub.m -OH, with a reactive derivative of xanthene-9-carboxylic acid, and, if desired, converting the obtained product into its salt.
