哺乳动物细胞将花生四烯酸代谢为许多不同的产物,包括各种羟基脂肪酸(1)。这些羟基脂肪酸中的大多数由脂氧合酶形成。三种最常见的脂氧合酶是存在于白细胞和巨噬细胞等细胞中的5-和15-脂氧合酶,以及存在于肥大细胞、血小板和表皮细胞中的12-脂氧合酶。这些脂氧合酶将花生四烯酸代谢为过氧化氢二十碳四烯酸(HPETE)。HPETE不稳定,并且容易被细胞过氧化物酶还原为相应的稳定的单羟基二十碳四烯酸(HETE)或转化为其他产物,包括白三烯、二HETE或THETE(2)。形成的产物的性质取决于特定脂氧合酶的特异性以及其他代谢酶如环氧化物合成酶、水解酶等的存在。通常HETE是主要的脂氧合酶产物。一些报告表明,11-和15-HETE也可以通过环氧合酶的脂氧合酶活性形成(1)。环氧合酶途径产生的主要羟基脂肪酸是12-羟基十七碳三烯酸(HHT)。
Mammalian cells metabolize arachidonic acid to many different products including a variety of hydroxy fatty acids (1). Most of these hydroxy fatty acids are formed by lipoxygenases. The three most common lipoxygenases are the 5- and 15-lipoxygenases, present in such cells as leukocytes and macrophages and the 12-lipoxygenase which is found in mast cells, platelets, and epidermal cells. These lipoxygenases metabolize arachidonic acid to hydroperoxyeicosatetraenoic acids (HPETEs). The HPETEs are unstable and are either readily reduced by cellular per-oxidases to the corresponding stable monohydroxyeicosatetraenoic acids (HETEs) or are converted to other products including leukotrienes, diHETEs or THETEs (2). The nature of the products formed depends on the specificity of the particular lipoxygenase as well as the presence of other metabolizing enzymes such as epoxide synthetase, hydrolases, etc. Usually the HETEs are the predominant lipoxygenase product. Several reports indicate that both 11- and 15-HETE can also be formed via the lipoxygenase activity of the cyclooxygenase enzyme (1). The major hydroxy fatty acid produced by the cyclooxygenase pathway is 12-hydroxyheptadecatrienoic acid (HHT).
