英文名:O,O-Dimethyl phosphoramidothioate; O,O-Dimethyl thiophosphoramidate;spermine;gerontine;musculamin;neuridine;Spermine H2N(CH2)3NH(CH2)4NH(CH2)3NH2;
Musculamine;N,N′-Bis(3-aminopropyl)tetramethylenediamine;N,N′-Bis(3-aminopropyl)-1,4-butanediamine ;Diaminopropyltetramethylenediamine , 1,12-Diamino-4,9-diazadodecane
中文名:精胺; 精素;精碱;N,N′-双(3-氨丙基)-1,4-丁二胺,α,δ-双(γ-氨丙氨基)丁烷; 1,12-二氨基-4,9-二氮十二烷O;O-二甲基硫代磷酰胺
性质: 沸点130℃(13.3Pa)。在0~4℃保存。是含有两个氨基和两个亚氨基的多胺类物质,在生物体内由腐胺和S-腺苷蛋酸经多种酶催化后生成。它与亚精胺都存在于细菌和大多数动物细胞中,是促进细胞增殖的重要物质。在酸性条件下,它呈现出多阳离子多胺类特性,并能与病毒与细菌中DNA结合。使DNA分子具有更大的稳定性与柔韧性:也是细胞培养液中必要组分之一。

Description
Biochem/physiol Actions Mixed NMDA glutamate receptor agonist/antagonist at the polyamine site. Neuroprotective effects have been observed at high concentrations (1 mM), while neurotoxicity is observed at lower concentrations. It enhances agonist effectiveness at the strychnine-insensitive glycine site. Plays a role in cellular proliferation and differentiation; inhibits neuronal nitric oxide synthase (nNOS).
