2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-4H-chromen-4-one

C15H10O6 (286.047736)


Luteolin is a naturally occurring flavonoid. (PMID:17168665). The flavonoids are polyphenolic compounds found as integral components of the human diet. They are universally present as constituents of flowering plants, particularly of food plants. The flavonoids are phenyl substituted chromones (benzopyran derivatives) consisting of a 15-carbon basic skeleton (C6-C3-C6), composed of a chroman (C6-C3) nucleus (the benzo ring A and the heterocyclic ring C), also shared by the tocopherols, with a phenyl (the aromatic ring B) substitution usually at the 2-position. Different substitutions can typically occur in the rings, A and B. Several plants and spices containing flavonoid derivatives have found application as disease preventive and therapeutic agents in traditional medicine in Asia for thousands of years. The selection of a particular food plant, plant tissue or herb for its potential health benefits appears to mirror its flavonoid composition. The much lower risk of colon, prostate and breast cancers in Asians, who consume more vegetables, fruits and tea than populations in the Western hemisphere do, raises the question of whether flavonoid components mediate the protective effects of diets rich in these foodstuffs by acting as natural chemopreventive and anticancer agents. An impressive body of information exists on the antitumoral action of plant flavonoids. In vitro work has concentrated on the direct and indirect actions of flavonoids on tumor cells, and has found a variety of anticancer effects such as cell growth and kinase activity inhibition, apoptosis induction, suppression of the secretion of matrix metalloproteinases and of tumor invasive behavior. Furthermore, some studies have reported the impairment of in vivo angiogenesis by dietary flavonoids. Experimental animal studies indicate that certain dietary flavonoids possess antitumoral activity. The hydroxylation pattern of the B ring of the flavones and flavonols, such as luteolin seems to critically influence their activities, especially the inhibition of protein kinase activity and antiproliferation. The different mechanisms underlying the potential anticancer action of plant flavonoids await further elucidation. Certain dietary flavonols and flavones targeting cell surface signal transduction enzymes, such as protein tyrosine and focal adhesion kinases, and the processes of angiogenesis appear to be promising candidates as anticancer agents. Further in vivo studies of these bioactive constituents is deemed necessary in order to develop flavonoid-based anticancer strategies. In view of the increasing interest in the association between dietary flavonoids and cancer initiation and progression, this important field is likely to witness expanded effort and to attract and stimulate further vigorous investigations (PMID:16097445). Luteolin is a tetrahydroxyflavone in which the four hydroxy groups are located at positions 3, 4, 5 and 7. It is thought to play an important role in the human body as an antioxidant, a free radical scavenger, an anti-inflammatory agent and an immune system modulator as well as being active against several cancers. It has a role as an EC 2.3.1.85 (fatty acid synthase) inhibitor, an antineoplastic agent, a vascular endothelial growth factor receptor antagonist, a plant metabolite, a nephroprotective agent, an angiogenesis inhibitor, a c-Jun N-terminal kinase inhibitor, an anti-inflammatory agent, an apoptosis inducer, a radical scavenger and an immunomodulator.

Luteolin is a natural product found in Verbascum lychnitis, Carex fraseriana, and other organisms with data available. Luteolin is a naturally-occurring flavonoid, with potential anti-oxidant, anti-inflammatory, apoptosis-inducing and chemopreventive activities. Upon administration, luteolin scavenges free radicals, protects cells from reactive oxygen species (ROS)-induced damage and induces direct cell cycle arrest and apoptosis in tumor cells. This inhibits tumor cell proliferation and suppresses metastasis. 5,7,3,4-tetrahydroxy-flavone, one of the FLAVONES.

Oleanolic acid is a pentacyclic triterpene, found in the non-glyceride fraction of olive pomace oil (Olive pomace oil, also known as "orujo" olive oil, is a blend of refined-pomace oil and virgin olive oil, fit for human consumption). Pentacyclic triterpenes are natural compounds which are widely distributed in plants. These natural products have been demonstrated to possess anti-inflammatory properties. Triterpenoids have been reported to possess antioxidant properties, since they prevent lipid peroxidation and suppress superoxide anion generation. The triterpenes have a history of medicinal use in many Asian countries. Oleanolic acid exhibits both pro- and anti-inflammatory properties depending on chemical structure and dose and may be useful in modulating the immune response; further studies are required to confirm the immunomodulatory behaviour of this triterpenoid, and characterise the mechanisms underlying the biphasic nature of some aspects of the inflammatory response. Oleanolic acid is a ubiquitous triterpenoid in plant kingdom, medicinal herbs, and is an integral part of the human diet. During the last decade over 700 research articles have been published on triterpenoids research, reflecting tremendous interest and progress in our understanding of these compounds. This included the isolation and purification of these tritepernoids from various plants and herbs, the chemical modifications to make more effective and water soluble derivatives, the pharmacological research on their beneficial effects, the toxicity studies, and the clinical use of these triterpenoids in various diseases including anticancer chemotherapies.
