Cadaverine is an organic compound with the formula (CH₂)₅(NH₂)₂. Classified as a diamine, it is a colorless liquid with an unpleasant odor.^[3] It is present in small quantities in living organisms but is often associated with the putrefaction of animal tissue. Together with putrescine, it is largely responsible for the foul odor of putrefying flesh, but also contributes to other unpleasant odors.

Production

Cadaverine is produced by decarboxylation of lysine.^[4] It can be synthesized by many methods including the hydrogenation of glutaronitrile and the reactions of 1,5-dichloropentane.^[3]

History

Putrescine^[5] and cadaverine^[6] were first described in 1885 by the Berlin physician Ludwig Brieger (1849–1919).^[7]

Receptors

In zebrafish, the trace amine-associated receptor 13c (or TAAR13c) has been identified as a high-affinity receptor for cadaverine.^[8] In humans, molecular modelling and docking experiments have shown that cadaverine fits into the binding pocket of the human TAAR6 and TAAR8.^[9]

Clinical significance

Elevated levels of cadaverine have been found in the urine of some patients with defects in lysine metabolism. The odor commonly associated with bacterial vaginosis has been linked to cadaverine and putrescine.^[10]

Derivatives

Pentolinium and pentamethonium.

Toxicity

Acute oral toxicity of cadaverine is 2,000 mg/kg body weight; its no-observed-adverse-effect level is 2,000 ppm (180 mg/kg body weight/day).^[11]

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.)
