Millipedes (class Diplopoda) produce a myriad of defensive chemicals, including hydrogen cyanide, oxidized aromatics, and alkaloids . These compounds are stored in high concentrations in ozadenes (or rapidly generated from biological inert precursors) and the millipedes discharge the defensive agents upon disturbance. The alkaloids are the most structurally intriguing and least studied of all of the millipede defensive secretions, and found in one millipede subterclass, the Colobognatha (fungus-feeding millipedes). This subterclass is composed of four orders (Platydesmida, Polyzoniida, Siphonocryptida and Siphonophorida) and they are known to produce simple monoterpenes (pinenes and limonene), along with various heterocyclic terpenoid alkaloids [e.g. deoxybuzonamine
