Spermine

Spermine is a polyamine involved in cellular metabolism that is found in all eukaryotic cells. The precursor for synthesis of spermine is the amino acid ornithine. It is an essential growth factor in some bacteria as well. It is found as a polycation at physiological pH. Spermine is associated with nucleic acids and is thought to stabilize helical structure, particularly in viruses. It functions as an intracellular free radical scavenger to protect DNA from free radical attack. Antonie van Leeuwenhoek first described crystals of spermine phosphate in human semen in A derivative of spermine, N 1 , N 12 -bis ethyl spermine also known as BESm was investigated in the late s along with similar polyamine analogues for its potential as a cancer therapy. Spermine biosynthesis in animals starts with decarboxylation of ornithine by the enzyme Ornithine decarboxylase in the presence of PLP. This decarboxylation gives putrescine.

Spermidine is a polyamine compound C 7 H 19 N 3 found in ribosomes and living tissues and having various metabolic functions within organisms. It was originally isolated from semen. Spermidine is an aliphatic polyamine. Spermidine synthase SPDS catalyzes its formation from putrescine. It is a precursor to other polyamines, such as spermine and its structural isomer thermospermine. Spermidine is a longevity agent in mammals due to various mechanisms of action, which are just beginning to be understood. Autophagy is the main mechanism at the molecular level, but evidence has been found for other mechanisms, including inflammation reduction, lipid metabolism, and regulation of cell growth, proliferation, and death.

No new data were created or analyzed in this study. Data sharing is not applicable to this article. In recent years, research on spermine Spm has turned up a lot of new information about this essential polyamine, especially as it is able to counteract damage from abiotic stresses. Spm has been shown to protect plants from a variety of environmental insults, but whether it can prevent the adverse effects of drought has not yet been reported.

Role of polyamines in immune cell functions. Kitazume, N. Bertaggia, E. Polyamine catabolism and disease. SITE1 combines the substrate-binding site where spermine can be modeled in and the allosteric site under the newly formed loop covering JNJ Also transports organic cations such as tetraethylammonium TEA without the involvement of sodium. For the combination studies, the synergy was assessed using the combination index CI according to the Chou-Talalay method 66 using CompuSyn software version 1. Published : 26 June
