摘要: 哺乳动物中褪黑素(melatonin)主要是由松果体分泌的一种内源性吲哚胺,含有5-甲氧基和N-乙酰基侧链两个关键官能团,以此决定其特异性和双亲性。近年来,褪黑素及其代谢产物被认为具有抗氧化、抗炎、抗凋亡等多种生物活性,在哺乳动物复杂生理调节过程中发挥重要作用。本文主要围绕褪黑素生物合成与代谢、抗氧化机制及其在哺乳动物精子冷冻保存中的作用效应这3个方面对近期的研究进展进行综述,为深入研究褪黑素在动物细胞体外保存中的应用提供参考依据。

Abstract: Melatonin is an endogenous indole amine synthesized and secreted principally by the pineal gland in mammals. Distinct roles of 5-methoxy and N-acetyl groups determined the melatonin’s specificity and water-lipid solubility. In recent years, melatonin and its metabolites were proved to have an antioxidant, anti-inflammatory, anti-apoptotic and other biological activities, playing important roles in the complex physiological regulation of mammals. In this paper, we reviewed the research progress on biosynthesis and metabolism, antioxidant mechanisms of melatonin and its bio-effects on sperm cryopreservation, which will provide scientific basis for further research on the application of melatonin in in vitro preservation of animal cells.

Key words: melatonin, oxidative stress, mitochondria, sperm cryopreservation
