We here report the synthesis of the two polyamine-based nucleoside derivatives 5-{[bis-(3-aminopropyl)amino]acetamido-1-propynyl}uridine and 2-{[bis-(3-aminopropyl)amino]-acetamido-1-propynyl}adenosine. The various polyamine derivatives have been used in thermal melting analysis using DNA from herring testes, and in cellular studies using four different cell lines. The...

We have reported that spermidine N1-acetyltransferase has a larger role than ornithine decarboxylase in putrescine synthesis in chick duodenum induced by 1 alpha,25-dihydroxycholecalciferol (calcitriol) [Shinki, T., Kadofuku, T., Sato, T. and Suda, T. (1986) J. Biol. Chem. 261, 11712-11716]. In...

Polyamine aminotransferase of Arthrobacter sp. TMP-1 was induced by 1,3-diaminopropane (DAP), N-3-aminopropyl-1,3-diaminopropane (norspermidine), spermidine, and spermine, but not by putrescine. The enzyme was purified to homogeneity. Its molecular weight and subunit size were 129,000 and 64,000, respectively. Its absorption spectrum...

A series of novel spermidine and sym-norspermidine dimers was synthesized by crosslinking the polyamine backbones via alkylation of their secondary amino groups to butyl, trans-2-butenyl, 2-butynyl or p-xylyl bridges. The resulting hexamines behaved as high-affinity antagonists of polyamine uptake, with...

A library of polyamine-peptide conjugates based around some previously identified inhibitors of trypanothione reductase was synthesised by parallel solid-phase chemistry and screened. Kinetic analysis of library members established that subtle structural changes altered their mechanism of action, switching between competitive...
