Comparative study on the inhibitory effect of caffeic and chlorogenic acids on key enzymes linked to Alzheimer's disease and some pro-oxidant induced oxidative stress in rats' brain-in vitro. Considering the various combinations, a higher caffeine to caffeic acid ratio produced significantly highest enzyme modulatory effects; these were significantly lower to the effect of caffeine alone but significantly higher than the effect of caffeic acid alone. [13] Caffeic acid also shows immunomodulatory and anti-inflammatory activity. It is the precursor to ferulic acid, coniferyl alcohol, and sinapyl alcohol, all of which are significant building blocks in lignin. The transformation to ferulic acid is catalyzed by the enzyme caffeate O-methyltransferase. Oboh G, Agunloye OM, Akinyemi AJ, Ademiluyi AO, Adefegha SA.

Caffeate 3,4-dioxygenase is an enzyme that uses caffeic acid and oxygen to produce 3-(2-carboxyethenyl)-cis,cis-muconate. Caffeic acid, which is unrelated to caffeine, is biosynthesized by hydroxylation of coumaroyl ester of quinic acid (esterified through a side chain alcohol). HHS This yellow solid consists of both phenolic and acrylic functional groups. Use the link below to share a full-text version of this article with your friends and colleagues. Caffeic acid is listed under some Hazard Data sheets as a potential carcinogen,[20] as has been listed by the International Agency for Research on Cancer as a Group 2B carcinogen ("possibly carcinogenic to humans"). [26] Caffeic acid can also be polymerized using the horseradish peroxidase/H2O2 oxidizing system. [24], Caffeic acid is susceptible to autoxidation.With transition metals,it forms transition metal-carboxylate complexes,but not salts. 2020 Jul 28;9(8):675. doi: 10.3390/antiox9080675. Their cardiopotective and cardiomodulatory roles have been investigated due to their biological activities. Furthermore, the result showed a notable rise in ACE and arginase activities of L‐NAME‐induced group compared with the control group. [28] The developing chemistry is similar to that of catechol or pyrogallol. [21] More recent data show that bacteria in the rats' guts may alter the formation of metabolites of caffeic acid. Bratisl Lek Listy. If you do not receive an email within 10 minutes, your email address may not be registered, Therefore, in this study, we investigated the effect of caffeine, caffeic acid and their various combinations on activities of some enzymes [acetylcholinesterase (AChE), monoamine oxidase (MAO) ecto-nucleoside triphosphate diphosphohydrolase (E-NTPase), ecto-51-nucleotidase (E-NTDase) and Na+/K+ ATPase relevant to neurodegeneration in vitro in rat brain. This study supports that caffeine and caffeic acid combinations demonstrated antihypertensive properties by lowering the systolic blood pressure in L‐NAME‐induced rats. [7] It is also quite high in the South American herb yerba mate (150 mg per 100 g based on thin layer chromatography densiometry [8] and HPLC [9]). Jara-Palacios MJ, Gonçalves S, Heredia FJ, Hernanz D, Romano A. Antioxidants (Basel). Caffeic acid, which is unrelated to caffeine, is biosynthesized by hydroxylation of coumaroyl ester of quinic acid (esterified through a side chain alcohol). The combinations also exhibited Fe2+ and Cu2+ chelating abilities. Alkaloid extracts from Jimson weed (Datura stramonium L.) modulate purinergic enzymes in rat brain.  |  However, their different proportional distribution in food sources and possible effect of such interactions are not often taken into consideration. Caffeic acid might have a mild stimulating effect that could possibly worsen insomnia. Keywords: 2016 Sep;56:107-117. doi: 10.1016/j.neuro.2016.06.012. Learn more. [16], Caffeic acid has a variety of potential pharmacological effects in in vitro studies and in animal models, and the inhibitory effect of caffeic acid on cancer cell proliferation by an oxidative mechanism in the human HT-1080 fibrosarcoma cell line has recently been established.  |  Please check your email for instructions on resetting your password. Caffeic acid (3,4-dihydroxy-cinnamic acid) is an organic compound and a potent antioxidant. Extraction of Antioxidants from Winemaking Byproducts: Effect of the Solvent on Phenolic Composition, Antioxidant and Anti-Cholinesterase Activities, and Electrochemical Behaviour. [2], Caffeic acid can be found in the bark of Eucalyptus globulus[3] the barley grain H vulgaris and the herb Dipsacus asperoides. [19] Oral administration of high doses of caffeic acid in rats has caused stomach papillomas. Also, caffeic acid treatment attenuated lipopolysaccharide (LPS)-induced sickness behaviour in experimental animals by decreasing both peripheral and central cytokine levels along with oxidative stress inflicted by LPS. [6], Caffeic acid is found at a very modest level in coffee, at 0.03 mg per 100 ml. Caffeic acid has been shown to inhibit the multiplication of influenza A virus in vitro, whereas caffeine, quinic acid and chlorogenic acid do not. (.

Caffeic acid is an organic compound that is classified as a hydroxycinnamic acid. eCollection 2018 Jun. Acetylcholinesterase; Caffeic acid; Caffeine; Monoamine oxidase; Neuromodulation; Purinergic signalling. The stock concentration of caffeine and caffiec acid and their various proportional combinations were prepared and their interactions with the activities of these enzymes were assessed (in vitro) in different brain structures. 2013 Feb;38(2):413-9. doi: 10.1007/s11064-012-0935-6. Caffeic acid has also been shown to have antiviral activity against herpes simplex virus (DNA virus) and polio virus (RNA virus). This study supports that caffeine and caffeic acid combinations demonstrated antihypertensive properties by lowering the systolic blood pressure in L‐NAME‐induced rats. Chemical oxidation of caffeic acid in acidic conditions using sodium periodate leads to the formation of dimers with a furan structure (isomers of 2,5-(3′,4′-dihydroxyphenyl)tetrahydrofuran 3,4-dicarboxylic acid). The results revealed that caffeine, caffeic acid and their various combinations exhibited inhibitory effect on activities of AChE, MAO, E-NTPase and E-NTDase, but stimulatory effect on Na+/K+ ATPase activity. The studies are the first to show that oxidative stress that would otherwise trigger or enhance Aspergillus flavus aflatoxin production can be stymied by caffeic acid. [4] It can also be found in the freshwater fern Salvinia molesta[5] and in the mushroom Phellinus linteus. These findings may provide new insight into the effect of proportional combination of these bioactive compounds as obtained in many foods … It is found at a high level in some herbs, especially thyme, sage and spearmint (at about 20 mg per 100 g), at high levels in spices, especially Ceylon cinnamon and star anise (at about 22 mg per 100 g), found at fairly high level in sunflower seeds (8 mg per 100 g), and at modest levels in red wine (1.88 mg per 100 ml) and in apple sauce, apricots and prunes (at about 1 mg per 100 g). This hydroxylation produces the caffeic acid ester of shikimic acid, which converts to chlorogenic acid.
