The diamine putrescine, the triamine spermidine, and the tetramine spermine are ubiquitous
in plant cells, while other polyamines are of more limited occurrence. Their chemistry and …

The pharmacology of polyamines has been reviewed quite extensively in many books and
articles prior to 1991 (1-9). The number of publications relating to polyamines continues to …

The uptake and release of the natural polyamines putrescine, spermidine and spermine by
mammalian cells are integral parts of the systems that regulate the intracellular …

Interest in ornithine decarboxylase (ODC) and the therapeutic effects of its inhibition with the
consequent depletion of polyamine biosynthesis has been widespread since the late 1970s …

This work is aimed at reviewing the chemical literature dealing with thermodynamic aspects
of the weak complex formation (species with logK values less than about 3) between alkali …

As soon as the natural polyamines (PAs), putrescine (Put), spermidine (Spd) and spermine
(Spm), were recognized as ubiquitous constituents of eukaryotic cells, their involvement in …

Currently, two major pathways are distinguished along which the polyamines are
metabolized: the interconversion pathway and the so-called terminal polyamine catabo lism …

The polyamines spermine, spermidine, and putrescine are small organic molecules one or
more of which are present in all living organisms. Many natural products contain polyamine …

A lack of molecular contrast agents has slowed the application of ultrasensitive
hyperpolarized 129Xe NMR methods. Here, we report that commercially available cucurbit …

The permeability of the blood‐nerve barrier (BNB) and the blood‐brain barrier (BBB) to
superoxide dismutase (SOD), insulin, albumin, and IgG in normal adult rats was quantified …
