TRICYCLIC AND TETRACYCLIC SYSTEMS WITH ACTIVITY ON THE CENTRAL-NERVOUS AND VASCULAR SYSTEMS

摘要

This invention is related to chemistry and pharmacy and in particular to the production of novel molecular entities: tricyclic and tetracyclic derivatives of the benzodiazepine pyridodiazepine and pyrimidodiazepine type fused with 1 4-dihydropyridine derivatives acting upon the Vascular and Central Nervous Systems. From derivatives containing a dihydropyridine ring reacting with compounds of the ortho-phenyldiamine ortho-diaminopyridine and ortho-diaminopyrimidine type as well as some subsequent transformations thereof tricyclic and tetracyclic derivatives ....
