Abstract:
Purified maize polyamine oxidase bound to hydroxylapatite was utilized as an enzymatic reactor to produce oxidized spermidine and spermine. The oxidation products showed a consistent inhibitory activity on Leishmania infantum in mice. 1,3-diaminopropane showed a much lower activity. Moreover chemically prepared 4-aminobutyraldehyde had a similar ED50 to that of oxidized spermidine. It is concluded that among the compounds arising from polyamine oxidation those with the greatest anti-leishmanial effect are 4-aminobutyraldehyde and 1-(3-aminopropyl)-4-aminobutyraldehyde.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
