产品应用

• 混合NMDA谷氨酸受体在多胺位点上的激动剂/拮抗剂。在高浓度(1 mM)时已被观察到具神经保护作用，而在低浓度时，可观察到具有神经毒性。它增强了在马钱子碱不敏感的甘氨酸位点的反作用。对细胞增殖和分化起主要作用;抑制神经元一氧化氮合成酶（nNOS）。
• 精胺、腐胺及亚精胺组成了多胺家族（polycations，聚阳离子），这对于绝大多数的活细胞生长和生存是必需的。多胺与带负电荷的分子相互作用，如蛋白多糖(proteoglycans)，糖化蛋白(glycated proteins)和核酸（DNA和RNA）。生物多胺被发现在不同层次可调控蛋白合成。这种影响可被解释为多胺结合和影响tRNA，mRNA和rRNA的二级结构。精胺也有助于稳定核酸螺旋结构并组成糖化蛋白如组蛋白（the histones）。精胺和亚精胺是各种核酸转染方案的组件。

其他信息

• Spermine is a biogenic polyamine formed from spermidine and occurs in almost all tissues. It is essential for both neoplastic and normal tissue growth and is involved in the modulation of calcium-dependent immune processes. Spermine inhibits NOS1 (nNOS). Spermine binds to and activates NMDA and has been shown to potentiate NMDA-induced currents in a concentration-dependent manner. Spermine is a GluR inhibitor.
