Use

There is little information available on the metabolism and disposition of dipropylamine in biological systems. The available evidence suggests that dipropylamine is not a substrate for monoamine oxidase, but rather is inhibitory. Valiev (1974) administered dipropylamine intraperitoneally to rats and reported it to be moderately inhibitory to liver monoamine oxidase. Previous work by this author demonstrated that lethal doses of dipropylamine and other secondary and tertiary amines significantly inhibited rat liver monoamine oxidase activity (Valiev 1968). The carcinogenic N-nitrosodipropylamine has been detected in the stomach when dipropylamine (present in fish, vegetables and fruit juices) comes in contact with nitrite, which is often used as a food additive in meats and smoked fish (HSDB 1989). Further metabolism of the carcinogen N-nitrosodipropylamine product formed upon nitrosation of dipropylamine is required to form a highly electrophilic carbonium ion capable of alkylating DNA, etc. (Archer 1981).
