title: Heterocyclic tricycles as potential CNS agents I: 4-aminoalkylindeno[1,2-c]pyrazoles.
abstract: Series of 4-(3-dimethylaminopropyl)-4-hydroxyindeno[1,2-c]pyrazoles and 4-(1-methyl-4-piperidyl)-4-hydroxyindeno[1,2-c-]pyrazoles were synthesized and identified. The compounds were evaluated as potential CNS agents using spontaneous and forced motor activity in mice as an initial test. 2-Ethyl-3-methyl-4-(1-methyl-4-piperidyl)-4-hydroxyindeno[1,2-c]pyrazole possessed significant biological activity.
