title: Synthesis and pharmacological properties of decahydro-5H-pyrido [1',2'; 5,1]imidazo[3,4-a]-beta-carbolines.
abstract: Cyclic aminals (1-4) including a form of decahydro-5H-pyrido[1', 2'; 5, 1] imidazo [3, 4-a]-beta-carboline were obtained by treating erythro 1-(2'-piperidyl)-1,2,3,4-tetrahydro-beta-carboline with aldehydes. The central action of compounds 1-4 has been investigated using behavioral tests in mice and rats. The most active aminal was a phenyl derivative 4, which showed an anticonvulsive activity in the maximal electroshock seizure test. The overall activity of compound 4 was less potent than that of phenytoin.
