Improving Chilling Tolerance of Maize Seedlings under Cold Conditions by Spermine Application
Notulae Scientia Biologicae, 2012 Low temperature is an important abiotic stress which reduces crops growth and productivity and causes physiological damages to cellular structures. The aim of this study was to investigate the probability of spermine application to improve chilling ...

Metabolism of N-alkylated spermine analogues by polyamine and spermine oxidases [PDF]
Amino Acids, 2009 N-alkylated polyamine analogues have potential as anticancer and antiparasitic drugs. However, their metabolism in the host has remained incompletely defined thus potentially limiting their utility. Here, we have studied the degradation of three different spermine analogues N,N'-bis-(3-ethylaminopropyl)butane-1,4-diamine (DESPM), N-(3-benzyl ...

Angewandte Chemie, EarlyView.We introduce a novel chemical derivatisation strategy for the UV‐activated detection of elusive metabolites. Incorporation of a tocopherol‐active chromophore allows for the detection of tagged analytes as photoionised radical cations, selectively induced by a 266 nm laser.

Au(I) Complex With an Abnormal Carbene Ligand Shows Anti‐Kasha Dual Photoluminescence Emission
Angewandte Chemie, EarlyView.Incorporation of an abnormal N‐heterocyclic carbene into a heteroleptic linear Au(I) complex induces anti‐Kasha dual emission responsive to biologically relevant phenyl sulfate. ABSTRACT We report the first photoactive linear Au(I) complex with an abnormal N‐heterocyclic carbene (aNHC) ligand, Au(aIm)(Cz).

SPERMINE OXIDASE: AN AMINE OXIDASE WITH SPECIFICITY FOR SPERMINE AND SPERMIDINE [PDF]
Journal of Experimental Medicine, 1953 Sheep serum and bovine serum contain an enzyme which brings about a rapid oxidative deamination of certain biological amines. This enzyme differs from previously described amine oxidases in several regards and especially in its substrate specificity.

Journal of BacteriologyMycobacterium tuberculosis is well adapted to survive and persist in the infected host, escaping the host’s immune response. Since polyamines such as spermine, which are synthesized by infected macrophages, are able to inhibit the growth of M ...

Polyamine Homeostasis in Snyder-Robinson Syndrome
Medical Sciences, 2018 Loss-of-function mutations of the spermine synthase gene (SMS) result in Snyder-Robinson Syndrome (SRS), a recessive X-linked syndrome characterized by intellectual disability, osteoporosis, hypotonia, speech abnormalities, kyphoscoliosis, and seizures ...

Biomedicines, 2022 In mammalian cells, the content of polyamines is tightly regulated. Polyamines, including spermine, spermidine and putrescine, are involved in many cellular processes. Spermine oxidase specifically oxidizes spermine, and its deregulated activity has been

Antimycotic Effect of Spermine.
Experimental Biology and Medicine, 1958 Summary1) Spermine inhibited growth of several species of yeasts, Saccharomyces and Debaryomyces species being the most sensitive. The antimycotic effect of spermine was more pronounced at an alkaline pH and was antagonized by inorganic salts. The adsorption of spermine by yeast cells was significantly smaller than by Staph. aureus.
