花生四烯酸通过5-脂氧合酶氧化代谢形成5-氢-过氧-6-反式-8-顺式-二十碳四烯酸(5-HPETE),随后5-HPETE酶促转化为5,6-氧化-7,9-反式-11,14-顺式-二十碳四烯酸(LTA 4)。环氧化物水解酶将LTA 4转化为5S,12 R-二羟基-6,14-顺式-8,10-反式-二十碳四烯酸(LTB 4),而谷胱甘肽-S-转移酶加合谷胱甘肽以产生5S-羟基-6 R-S-谷亚硫酰基-7,9-反式-11,14-顺式-二十碳四烯酸(LTC 4)。谷氨酸的γ-谷氨酰转肽酶和甘氨酸的二肽酶依次裂解分别形成5S-羟基-6 R-S-半胱氨酰甘氨酰-7,9-反式-11,14-顺式-二十碳四烯酸(LTD 4)和5S-羟基-6 R-S-半胱氨酰-7,9-反式-11,14-顺式-二十碳四烯酸(LTE 4)。白三烯C4、D4和E4一般被描述为硫肽白三烯,并构成了先前称为过敏反应慢反应物质的活性(Samuelsson,1983;刘易斯和Austen,1984)。表明硫肽白三烯通过与几种不同的受体相互作用发挥其生理作用的证据包括它们对不同组织的不同功能活性、药理学抑制剂对三种硫肽白三烯的激动剂作用的不同作用、通过放射性配体结合研究确定的不同受体特征、硫肽白三烯结合位点的亚细胞分布存在明显差异。
The oxidative metabolism of arachidonic acid by 5-lipoxygenase to form 5-hydro-peroxy-6-trans8-cis-eicosatetraenoic acid (5-HPETE) is followed by enzymatic conversion of 5-HPETE to 5,6-oxido-7,9-trans-ll,14-cis-eicosatetraenoic acid (LTA4). An epoxide hydrolase converts LTA4 to 5S,12R-dmydroxy-6,14-cis-8,10-trans-eicosatetraenoic acid (LTB4), whereas a glutathione-S-transferase adducts glu-tathione to yield 5S-hydroxy-6R-S-gluta.thionyl-7,9-trans-11.14-cis-eicossitrae-noic acid (LTC4). Sequential cleavages by γ-glutamyltranspeptidase of glutamic acid and by a dipeptidase of glycine form 5S-hydroxy-6R-S-cysteinylglycyl-7,9-trans-11 1,14-cis-eicosatetraenoic acid (LTD4) and 5S-hydroxy-6R-S-cysteinyl-7,9-trans-11,14-cis-eicosatetraenoic acid (LTE4), respectively. Leukotrienes C4, D4, and E4 are generically described as sulfidopeptide leukotrienes and constitute the activity previously termed slow reacting substance of anaphylaxis (Samuelsson, 1983; Lewis and Austen, 1984). The evidence indicating that the sulfidopeptide leukotrienes exert their physiological effects through interaction with several distinct receptors includes their differential functional activities on different tissues, the differential effects of pharmacological inhibitors on the agonist effects of the three sulfidopeptide leukotrienes, different receptor characteristics defined by radioligand binding studies, and apparent differences in the subcellular distribution of sulfi-dopeptide leukotriene binding sites.
