摘要

摘要在过去的几十年里，绿色植物色素叶绿素的降解一直吸引着化学家和生物学家。然而，在这种生物化学降解途径中形成的化合物的生物活性最近才被发现。这些在植物衰老过程中由叶绿素形成的天然化合物现在被称为叶胆素。在这篇综述中，我们简要讨论了叶绿素降解，并概述了迄今为止已知的所选叶胆素的生物活性（叶胆素、二氧杂环丁烷型叶胆素和叶黄素），我们还强调了最近发现的黄色叶黄素的免疫调节作用。

The advent of phyllobilins as bioactive phytochemicals – natural compounds derived from chlorophyll in medicinal plants and food with immunomodulatory activities

Abstract The degradation of the green plant pigment chlorophyll has fascinated chemists and biologists alike over the last few decades. Bioactivities of the compounds formed in this biochemical degradation pathway, however, have only come to light recently. These natural compounds that are formed from chlorophyll during plant senescence are now called phyllobilins. In this review, we shortly discuss chlorophyll degradation and outline the so-far known bioactivities of selected phyllobilins (phylloleucobilin, dioxobilin-type phylloleucobilin, and phylloxanthobilin), and we also highlight the recently discovered immunomodulatory effects of a yellow phylloxanthobilin.

期刊介绍： Pteridines is an open acess international quarterly journal dealing with all aspects of pteridine research. Pteridines are heterocyclic fused ring compounds involved in a wide range of biological functions from the color on butterfly wings to cofactors in enzyme catalysis to essential vitamins. Of the pteridines, 5,6,7,8-tetrahydrobiopterin is the necessary cofactor of several aromatic amino acid monoxygenases, the nitric oxide synthases and glyceryl ether monoxygenase (GEMO). Neopterin plays an essential role in the immune system and is an important biomarker in laboratory medicine for diseases such as HIV, cardiovascular disease, malignant tumors, among others. Topics: -Neopterin, dihydroneopterin, monapterin- Biopterin, tetrahydrobiopterin- Folates, antifolates, riboflavin- Phenylalanine, tyrosine, phenylketonuria, serotonin, adrenalin, noradrenalin, L-DOPA, dopamine, related biogenic amines- Phenylalanine hydroxylase, tyrosine hydroxylase, tryptophan hydroxylase, nitric oxide synthases (iNOS), alkylglycerol monooxygenase (AGMO), dihydropterin reductase, sepiapterin reductase- Homocysteine, mediators of inflammation, redox systems, iron.
