应用
精胺是一种多阳离子生物多胺，来源于亚精胺，可作为补充剂或调节剂广泛应用于生物领域。用作负离子模式下唾液酸化聚糖 MALDI-MS 的 DHB 共基质。
生化/生理作用
多胺位点混合型 NMDA 谷氨酸受体激动剂/拮抗剂。在高浓度 (1mM) 下观察到神经保护作用，而在低浓度下则观察到神经毒性。它在番木鳖碱-不敏感性甘氨酸位点能够增强激动剂效应。在细胞增殖和分化中发挥作用；抑制神经元一氧化氮合成酶 (nNOS)。

Negative-ion matrix-assisted laser desorption/ionization mass spectra of sialyated glycoconjugates were acquired employing 2,5-dihydroxybenzoic acid (DHB) in conjunction with spermine as a co-matrix. The addition of spermine to DHB permitted an improved crystal formation as well as a higher analyte solubility.

The naturally occurring polyamines, spermidine, spermine, and their precursor putrescine, play indispensible roles in both prokaryotic and eukaryotic cells, from basic DNA synthesis to regulation of cell proliferation and differentiation. The rate-limiting polyamine biosynthetic enzymes, ornithine decarboxylase (ODC) and S-adenosylmethionine

Dextran-spermine cationic polysaccharide was prepared by means of reductive amination between oxidized dextran and the natural oligoamine spermine. The formed Schiff-base imine-based conjugate was reduced with borohydride to obtain the stable amine-based conjugate. The transfection efficiency of the synthetic dextran-spermine

In rat models of drug relapse and craving, cue-induced cocaine seeking progressively increases after withdrawal from the drug. This 'incubation of cocaine craving' is partially mediated by time-dependent adaptations at glutamatergic synapses in nucleus accumbens (NAc). However, the circuit-level adaptations
