Cadaverine is a foul-smelling compound produced by protein hydrolysis during putrefaction of animal tissue. Cadaverine is a toxic^[1] diamine with the formula NH₂(CH₂)₅NH₂, which is similar to putrescine. Cadaverine is also known by the names 1,5-pentanediamine and pentamethylenediamine.

History

Putrescine^[2] and cadaverine^[3] were first described in 1885 by the Berlin physician Ludwig Brieger (1849–1919).^[4]

Production

Cadaverine is the decarboxylation product of the amino acid lysine.

However, this diamine is not purely associated with putrefaction. It is also produced in small quantities by living beings. It is partially responsible for the distinctive odors of urine and semen.

Clinical significance

Elevated levels of cadaverine have been found in the urine of some patients with defects in lysine metabolism.

Toxicity

Cadaverine is toxic in large doses. In rats it had an acute oral toxicity of more than 2000 mg/kg body weight.^[5]

From page 39: Ich nenne das neue Diamin C₅H₁₆N₂: "Cadaverin", da ausser der empirischen Zussamsetzung, welche die neue Base als ein Hydrür des Neuridins für den flüchtigen Blick erscheinen lässt, keine Anhaltspunkte für die Berechtigung dieser Auffassung zu erheben waren. (I call the new di-amine, C₅H₁₆N₂, "cadaverine," since besides its empirical composition, which allows the new base to appear superficially as a hydride of neuridine, no clues for the justification of this view arose.)
