Synthesis and pharmacological properties of alkylammonium salts of N,N′-malonyl-bis-p-aminobenzoic acid

A series of ammonium salts of N,N′-malonyl-bis-p-aminobenzoic acid with some alkylamines have been obtained. It is established that these compounds possess hypotensive, antiarrhythmic, and anticoagulative activities depending on the structure of the alkylamine constituents.
