α, є-pentamethy lenediamine, NH 2(CH 2)5 NH2. A colorless liquid with a boiling point of 178°-179°C. Cadave-rine is readily soluble in water and alcohol and yields crystallizing salts. It is contained in the products of protein decay (putrefaction) and is formed from lysine during its fermentative decarboxylation. Previously, cadaverine was thought of as one of the ptomaines, but the toxicity of cadaverine is relatively low. Cadaverine is found in plants and can be obtained synthetically from trimethylenecyanide.


C5H14N2 A nontoxic, organic base produced as a result of the decarboxylation of lysine by the action of putrefactive bacteria on flesh.

The effects of different levels of cadaverine as potential inhibitors of enzyme activity were observed in this study.
The inhibition seen at 20-40 mM concentration may not be relevant to the in vivo regulation of lysine decarboxylase activity, because cadaverine concentration in vivo have been found to be very low (Table 5).
The effect of cadaverine as a potential inhibitor was also observed on growth of isolates in BTJA.
