The Syrian hamster epididymis contains rather high levels of sym-homospermidine, N1-acetylspermidine and N1-acetylspermine in addition to the common polyamines putrescine, spermidine, and spermine. In the present study two other polyamines were identified in adult hamster epididymis by gas chromatography; they are aminopropylhomospermidine [NH2(CH2)3NH(CH2)4NH(CH2)4NH2] and canavalmine [NH2(CH2)4NH(CH2)3NH(CH2)4NH2]. The molar ratio of the former to the latter was about 2:1. This is the first report to show that tetraamines other than spermine are present in mammalian tissues.
叙利亚仓鼠附睾中除了含有常见的多胺腐胺、亚精胺和精胺外，还含有相当高水平的对称高亚精胺、N1-乙酰亚精胺和N1-乙酰精胺。在本研究中，通过气相色谱法在成年仓鼠附睾中鉴定出另外两种多胺；它们是氨丙基高亚精胺[NH2(CH2)3NH(CH2)4NH(CH2)4NH2]和刀豆胺[NH2(CH2)4NH(CH2)3NH(CH2)4NH2]。前者与后者的摩尔比约为2:1。这是首次报道哺乳动物组织中存在除精胺以外的四胺。
