A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
The determination of the pattern of genes expressed at the level of GENETIC TRANSCRIPTION, under specific circumstances or in a specific cell.

The rate dynamics in chemical or physical systems.
A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
Tumors or cancer of the LUNG.

Protective effect of flavonoids on endothelial cells against linoleic acid hydroperoxide-induced toxicity. (1/177)

The protective effect of flavonoids against linoleic acid hydroperoxide (LOOH)-induced cytotoxicity was examined by using cultured endothelial cells. When the cells were incubated with both LOOH and flavonoids, most flavonols protected the cells from injury by LOOH. Flavones bearing an ortho-dihydroxy structure also showed a protective effect against the cytotoxicity of LOOH. However, flavanones had no effect. The structure-activity relationship revealed the presence of either the ortho-di-hydroxy structure in the B ring of the flavonoids or 3-hydroxyl and 4-oxo groups in the C ring to be important for the protective activities. The interaction between flavonoids and a-tocopherol was also examined in this system. Flavonoids that were protective against LOOH-induced cytotoxicity had at least an additive effect on the action of alpha-tocopherol against LOOH-induced damage.  (+info)

Effects of luteolin and quercetin, inhibitors of tyrosine kinase, on cell growth and metastasis-associated properties in A431 cells overexpressing epidermal growth factor receptor. (2/177)

1. Flavonoids display a wide range of pharmacological properties including anti-inflammatory. Anti-mutagenic, anti-carcinogenic and anti-cancer effects. Here, we evaluated the effects of eight flavonoids on the tumour cell proliferation, cellular protein phosphorylation, and matrix metalloproteinase (MMPs) secretion. 2. Of the flavonoids examined, luteolin (Lu) and quercetin (Qu) were the two most potent agents, and significantly inhibited A431 cell proliferation with IC50 values of 19 and 21 micronM, respectively. 3. The epidermal growth factor (EGF) (10 nM) promoted growth of A431 cells (+25+/-4.6%) and mediated epidermal growth factor receptor (EGFR) tyrosine kinase activity and autophosphorylation of EGFR were inhibited by Lu and Qu. At concentration of 20 micronM, both Lu and Qu markedly decreased the levels of phosphorylation of A431 cellular proteins, including EGFR. 4. A431 cells treated with Lu or Qu exhibited protuberant cytoplasmic blebs and progressive shrinkage morphology. Lu and Qu also time-dependently induced the appearance of a ladder pattern of DNA fragmentation, and this effect was abolished by EGF treatment. 5. The addition of EGF only marginally diminished the inhibitory effect of luteolin and quercetin on the growth rate of A431 cells, treatment of cellular proteins with EGF and luteolin or quercetin greatly reduced protein phosphorylation, indicating Lu and Qu may act effectively to inhibit a wide range of protein kinases, including EGFR tyrosine kinase. 6. EGF increased the levels of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9), while Lu and Qu appeared to suppress the secretion of these two MMPs in A431 cells. 7. Examination of the relationship between the chemical structure and inhibitory effects of eight flavonoids reveal that the double bond between C2 and C3 in ring C and the OH groups on C3' and C4' in ring B are critical for the biological activities. 8. This study demonstrates that the inhibitory effects of Lu and Qu, and the stimulatory effects of EGF, on tumour cell proliferation, cellular protein phosphorylation, and MMP secretion may be mediated at least partly through EGFR. This study supports the idea that Lu and Qu may have potential as anti-cancer and anti-metastasis agents.  (+info)

Luteolin, an abundant dietary component is a potent anti-leishmanial agent that acts by inducing topoisomerase II-mediated kinetoplast DNA cleavage leading to apoptosis. (3/177)

BACKGROUND: Plant-derived flavonoids, which occur abundantly in our daily dietary intake, possess antitumor, antibacterial, and free radical scavenging properties. They form active constituents of a number of herbal and traditional medicines. Several flavonoids have been shown to exert their action by interacting with DNA topoisomerases and promoting site-specific DNA cleavage. Therefore, flavonoids are potential candidates in drug design. We report here that, although the flavonoids luteolin and quercetin are potent antileishmanial agents, luteolin has great promise for acting as a lead compound in the chemotherapy of leishmaniasis, a major concern in developing countries. MATERIALS AND METHODS: Kinetoplast DNA (kDNA) minicircle cleavage in drug-treated parasites was measured by electrophoresis of the total cellular DNA, followed by Southern hybridization using 32P labeled kDNA as a probe. Cell cycle progression and apoptosis were measured by flow cytometry using propidium iodide and fluorescein isothiocyanate (FITC)-labeled Annexin V. RESULTS: Luteolin and quercetin inhibited the growth of Leishmania donovani promastigotes and amastigotes in vitro, inhibited DNA synthesis in promastigotes, and promoted topoisomerase-II-mediated linearization of kDNA minicircles. The IC50 values of luteolin and quercetin were 12.5 microM and 45.5 microM, respectively. These compounds arrest cell cycle progression in L. donovani promastigotes, leading to apoptosis. Luteolin has no effect on normal human T-cell blasts. Both luteolin and quercetin reduced splenic parasite burden in animal models. CONCLUSION: Luteolin and quercetin are effective antileishmanial agents. Quercetin has nonspecific effects on normal human T cells, but luteolin appears nontoxic. So, luteolin can be a strong candidate for antileishmanial drug design.  (+info)

Flavonoids inhibit cell growth and induce apoptosis in B16 melanoma 4A5 cells. (4/177)

We investigated the growth inhibitory activity of several flavonoids, including apigenin, luteolin, kaempherol, quercetin, butein, isoliquiritigenin, naringenin, genistein, and daizein against B16 mouse melanoma 4A5 cells. Isoliquiritigenin and butein, belonging to the chalcone group, markedly suppressed the growth of B16 melanoma cells and induced cell death. The other flavonoids tested showed little growth inhibitory activity and scarcely caused cell death. In cells treated with isoliquiritigenin or butein, condensation of nuclei and fragmentation of nuclear DNA, which are typical phenomena of apoptosis, were observed by Hoechst 33258 staining and by agarose gel electrophoresis of DNA. Flowcytometric analysis showed that isoliquiritigenin and butein increased the proportion of hypodiploid cells in the population of B16 melanoma cells. These results demonstrate that isoliquiritigenin and butein inhibit cell proliferation and induce apoptosis in B16 melanoma cells. Extracellular glucose decreased the proportion of hypodiploid cells that appeared as a result of isoliquiritigenin treatment. p53 was not detected in cells treated with either of these chalcones, however, protein of the Bcl-2 family were detected. The level of expression of Bax in cells treated with either of these chalcones was markedly elevated and the level of Bcl-XL decreased slightly. Isoliquiritigenin did not affect Bcl-2 expression, but butein down-regulated Bcl-2 expression. From these results, it seems that the pathway by which the chalcones induce apoptosis may be independent of p53 and dependent on proteins of the Bcl-2 family. It was supposed that isoliquiritigenin induces apoptosis in B16 cells by a mechanism involving inhibition of glucose transmembrane transport and promotion of Bax expression. On the other hand, it was suggested that butein induces apoptosis via down-regulation of Bcl-2 expression and promotion of Bax expression. This mechanism differs from the isoliquiritigenin induction pathway.  (+info)

Luteolin inhibits an endotoxin-stimulated phosphorylation cascade and proinflammatory cytokine production in macrophages. (5/177)

Flavonoids are naturally occurring polyphenolic compounds with a wide distribution throughout the plant kingdom. In the present study, we compared the ability of several flavonoids to modulate the production of proinflammatory molecules from lipopolysaccharide (LPS)-stimulated macrophages and investigated their mechanism(s) of action. Pretreatment of RAW 264.7 with luteolin, luteolin-7-glucoside, quercetin, and the isoflavonoid genistein inhibited both the LPS-stimulated TNF-alpha and interleukin-6 release, whereas eriodictyol and hesperetin only inhibited TNF-alpha release. From the compounds tested luteolin and quercetin were the most potent in inhibiting cytokine production with an IC(50) of less than 1 and 5 microM for TNF-alpha release, respectively. To determine the mechanisms by which flavonoids inhibit LPS signaling, we used luteolin and determined its ability to interfere with total protein tyrosine phosphorylation as well as Akt phosphorylation and nuclear factor-kappaB activation. Pretreatment of the cells with luteolin attenuated LPS-induced tyrosine phosphorylation of many discrete proteins. Moreover, luteolin inhibited LPS-induced phosphorylation of Akt. Treatment of macrophages with LPS resulted in increased IkappaB-alpha phosphorylation and reduced the levels of IkappaB-alpha. Pretreatment of cells with luteolin abolished the effects of LPS on IkappaB-alpha. To determine the functional relevance of the phosphorylation events observed with IkappaB-alpha, macrophages were transfected either with a control vector or a vector coding for the luciferase reporter gene under the control of kappaB cis-acting elements. Incubation of transfected RAW 264.7 cells with LPS increased luciferase activity in a luteolin-sensitive manner. We conclude that luteolin inhibits protein tyrosine phosphorylation, nuclear factor-kappaB-mediated gene expression and proinflammatory cytokine production in murine macrophages.  (+info)

Inhibition of alpha-glucosidase and amylase by luteolin, a flavonoid. (6/177)

Twenty-one naturally occurring flavonoids were tested for inhibitory activities against alpha-glucosidase (EC and alpha-amylase (EC Luteolin, amentoflavone, luteolin 7-O-glucoside, and daidzein were the strongest inhibitors among the compounds tested. Luteolin inhibited alpha-glucosidase by 36% at the concentration of 0.5 mg/ml and was stronger than acarbose, the most widely prescribed drug, in inhibitory potency, suggesting that it has the possibility to effectively suppress postprandial hyperglycemia in patients with non-insulin dependent diabetes mellitus. Luteolin also inhibited alpha-amylase effectively although it was less potent than acarbose. The clinical value of luteolin needs to be further evaluated.  (+info)

In vitro absorption and metabolism of nobiletin, a chemopreventive polymethoxyflavonoid in citrus fruits. (7/177)

The polymethoxyflavonoid (PMF), nobiletin (NOB), specifically occurs in citrus fruits, and is currently believed to be a promising anti-inflammatory and antitumor promoting agent. In the present study, we investigated the in vitro absorption and metabolism of NOB and compared them with those of the polyhydroxyflavonoid (PHF), luteolin (LT). NOB preferentially accumulated in a differentiated Caco-2 cell monolayer, which is a model for small intestinal epithelial cells, while LT did not. Treatment of NOB with a rat liver S-9 mixture led to the formation of 3'-demethyl-NOB, while that of LT did not. We thus suggest that PMFs including NOB have properties distinct from those of general flavonoids for absorption and metabolism in vitro.  (+info)

Deglucuronidation of a flavonoid, luteolin monoglucuronide, during inflammation. (8/177)

In this study, we investigated whether luteolin monoglucuronide was converted to free aglycone during inflammation using human neutrophils stimulated with ionomycin/cytochalasin B and rats treated with lipopolysaccharide (LPS). beta-Glucuronidase activity was assayed using 4-methylumbelliferyl-glucuronide and methanol extracts of rat plasma containing luteolin monoglucuronide. The released 4-methylumbelliferone, a fluorescent molecule, was quantified by fluorometry. Deglucuronidation of luteolin monoglucuronide was examined by high-performance liquid chromatography (HPLC) analysis. HPLC analyses showed that the supernatants obtained from neutrophils stimulated with ionomycin/cytochalasin B hydrolyzed luteolin monoglucuronide to free luteolin. beta-Glucuronidase activity in human serum from patients on hemodialysis increased significantly compared with that from healthy volunteers. The beta-glucuronidase activity in rat plasma increased after i.v. injection of LPS. The ratio of luteolin to luteolin monoglucuronide in plasma of LPS-treated rats also increased. These results suggest that during inflammation beta-glucuronidase is released from stimulated neutrophils or certain injured cells and then deglucuronidation of flavonoids occurs.  (+info)

Here, we found that A431-III cells expressed a higher level of RPS12 than A431-P cells. The flavonoids luteolin and quercetin reduced RPS12 and c-Myc expressions via Akt/mTOR signalling. The Akt inhibitor LY294002 and mTOR inhibitor rapamycin reduced RPS12 and c-Myc expressions. The c-Myc inhibitor 10058-F4 reduced RPS12 expression and promoter transactivation. The overexpression of c-Myc increased RPS12 ...

The effectiveness of luteolin in diminishing clinical symptoms in crEAE rats after its onset was evaluated by treating crEAE animals with 50 mg/kg luteolin after the first clinical episode, from day 15 onwards. Clinical symptoms were completely abolished within 5 d of luteolin administration, whereas vehicle-treated crEAE animals suffered a severe relapse (Fig. 3 B). Upon ending treatment at day 24, luteolin-treated rats remained free of clinical symptoms until day 27, after which disease developed and progressed to become as severe as that in control crEAE animals (n = 5; not depicted). This indicates that the continuous presence of luteolin will be required to maintain suppression of crEAE.. As shown for the acEAE model (Fig. 1, C and D), luteolin treatment reduced the infiltration of leukocytes into the CNS in crEAE when treatment was started both at day 6 and at day 15. Significantly reduced numbers of macrophages (P , 0.05; Fig. 3 C) and T cells (P , 0.05; not depicted) were found in the ...

467 Prostate cancer (PCa) has become one of the most frequently diagnosed malignancies in the United States with similar trend in most Western countries. The substantial mortality and morbidity associated with PCa and its poor treatment options have led a surge to develop novel means for its prevention. The development of chemoprevention strategies against PCa would have huge impact, both medically and economically. Because of its ubiquity and disease burden, PCa is an attractive target for chemoprevention. Fisetin (3,3,4,7-tetrahydroxyflavone), is found in fruits andvegetables, such as strawberry, apple, persimmon, grape, onionand cucumber. The aim of this study was to determine the effect of fisetin on cell-growth and apoptosis in human PCa cells. Treatment of fisetin (10-60 μM; 48 h) was found to result in a decrease in the viability of LNCaP, CWR22Rυ1 and PC-3 cells but had only minimal effect on normal prostate epithelial PrEC cells as assessed by MTT assay.

Quercetin (QUE; 3,5,7,3′,4′-tetrahydroxyflavone) has been shown to possess several beneficial biological activities including antitumor, anti-inflammation and antioxidant properties; however, the effects of QUE in preventing invasion by breast carcinoma cells are still undefined. Increases in the protein, messenger RNA and enzyme activity levels of matrix metalloproteinase (MMP)-9 were observed in 12-O-tetradecanoylphorbol-13-acetate (TPA)-treated MCF-7 cells, and these were blocked by QUE, but not by quercitrin or rutin. A translocation of protein kinase C (PKC)δ from the cytosol to the membrane followed by activation of extracellular signal-regulated kinase (ERK) and c-Jun/activator protein-1 (AP-1) by TPA was demonstrated, and TPA-induced MMP-9 activation and migration were inhibited by the pan PKC inhibitor, GF109203X, the specific PKCδ inhibitor, rottlerin, an ERK inhibitor (PD98059) and an AP-1 inhibitor (curcumin). Application of QUE significantly suppressed TPA-induced activation ...
In the present work we investigated the banana peels (|i|Musa cavendishii|/i|) of organic silk variety from Pachacamac (Lurín, Lima) for being waste contaminants without use that avoid the damage to the environment. The qualitative presence of polyphenols and flavonoids was determined by phytochemical marching developed in ethanol extract of banana peels. Using thin layer chromatography on an analytical and preparative scale and rapid column chromatography, it was possible to separate nine soluble fractions in methanol and five soluble fractions in double distilled water as well as their respective Rf values; and by UV-visible spectrophotometry were elucidated nine structures of methanol soluble flavones (5,7-dihydroxy-4-methoxyflavone, 4,5,6,7-tetrahydroxyflavone, 5,7-dihydroxy-6-methoxyflavone, 4,5,7,8-tetrahydroxyflavone; 5,7,8-trihydroxyflavone, 45,7-trihydroxyflavone; 5,6-dihydroxy-7-methoxyflavone, 5,6,7-trihydroxy-4-methoxyflavone and 5,7-dihydroxy-4,6-dimethoxyflavone) and two flavones

Mnoge biljne vrste sadrže različite aktivne supstancije koje mogu pomoći pri liječenju ili ublažavanju simptoma određenih bolesti. Jedna vrsta takvih aktivnih tvari su polifenoli, za koje u posljednje vrijeme raste zanimanje upravo zbog brojnih znanstvenih dokaza o njihovom pozitivnom učinku na zdravlje. U ovom radu korištena je tekućinska kromatografija visoke djelotvornosti (HPLC) za kvalitativnu i kvantitativnu analizu polifenola u tri biljne vrste: Sambucus nigra, Artmisiia absinthium i Achillea millefolium. Detekcija ispitivanih polifenola izvršena je pomoću DAD detektora. U etanolnom ekstraktu biljne vrste Achillea millefolium pronađena je klorogenska kiselina, ružmarinska kiselina, ferulična kiselina te flavonoid luteolin, dok su u vodenom ekstraktu pronađene ferulična kiselina, klorogenska kiselina te ružmarinska kiselina.
