The synthesis of all three monoacetylated spermidines is reported. N4-Acetylspermidine was obtained in four steps from spermidine via the triacetylated intermediate by selective deacetylation after exhaustive t-butoxycarbonylation as well as directly from a previously described protected precursor. N1-Acetylspermidine and N8-acetylspermidine

The activity of two naturally occurring monoacetylated polyamines, N8-acetylspermidine and N1-acetylspermidine, as inducers of differentiation of HL60 human leukemia cells was assessed. Differentiation was quantified by morphological changes and the ability to reduce nitroblue tetrazolium. N8-Acetylspermidine produced 25-35 percent differentiation
Spermidine is one of the simple polyamines found in cells of virtually all living organisms. It undergoes a metabolic conversion to N8-acetylspermidine catalyzed by an enzyme in cell nuclei and is converted back to spermidine by a deacetylase in the

Polyamine oxidase plays a key role in the catabolism of polyamines and regeneration of spermidine and putrescine. The mammalian enzyme utilises N1-acetylspermidine, and N8-acetylspermidine, although formed in the mammals, is not catabolised further. We have characterised an enzyme from Acanthamoeba

The effect of Mg2+, putrescine, diaminopropane, N1-acetylspermidine, N8-acetylspermidine, spermidine, and spermine on the thermal denaturation of calf thymus DNA was investigated. As in a previous study with magnesium [W.F. Dove and N. Davidson, (1962) J. Mol. Biol. 5, 467-478], these
