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
Extracellular matrices, like collagen layers, play an important role in preventing dedifferentiation of hepatocytes in long-term culture experiments. It has also been shown that polyamines are crucial for cell growth and liver differentiation - regeneration. Primary cultured hepatocytes with their

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

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
