 * 1) Inhibition of neuronal nitric oxide synthase, nNOS
 * 2) Assisting the in vitro process of transcribing RNA via stimulation of T4 polynucleotide kinase and T7 RNA polymerase activity; it binds to and precipitates DNA and is utilized in purifying DNA-binding proteins
 * 3) Regulation and promotion of plant growth - as a polyamine plant growth regulator it is also a plant hormone-promoting somatic embryogenesis.
