Production of heavy metals by human activity is caused soil contaminations. The polyamines are used to reduction of heavy metal effects. In this study, the effects of lead and spermidine on Salvia officinalis L. were tested. A factorial experiment was conducted in a completely randomized design with three replications. Lead nitrate at concentrations of 0, 125, 250 and 1000 micro molar and sperm...

In order to improve quantitative and qualitative properties and vase life of rose cv. Dolcvita, an experiment was conducted in a randomized complete blocks design with ten treatments and three replications in a hydroponic greenhouse adjacent to Yasouj city, Iran. Treatments included control, spermidine (0.5, 1 and 1.5 mM), calcium sulfate (2.5 and 5 mM), spermidine 0.5 mM+ calcium sulfate 2.5 m...

Spermidine, N-(3-aminopropyl) butane-1,4-diamine, is a low-molecular-mass organic base (C7H19N3, CAS 124-20-9) and belongs to the polyamine family which includes spermine and putrescine, the direct precursor of spermidine (Figure 1). At ambient temperature (22-25 °C) spermidine is a colorless liquid or a white powder. In biological samples, the two primary amine groups and the secondary amine g...

Eighteen patients with melphalan refractory myeloma were treated with vindesine and prednisone. Plasma spermidine concentrations were measured by radioimmunoassay before and after a single vindesine injection. Seven patients showed a significant rise of plasma spermidine after vindesine and five of these showed a clinical response on further evaluation. Of the 11 patients who did not show raise...

A spermidine excretion protein in Escherichia coli was looked for among 33 putative drug exporters thus far identified. Cell toxicity and inhibition of growth due to overaccumulation of spermidine were examined in an E. coli strain deficient in spermidine acetyltransferase, an enzyme that metabolizes spermidine. Toxicity and inhibition of cell growth by spermidine were recovered in cells transf...
