Studies on the Biotransformation of Veratric Acid, a Human Metabolite of Mebeverine, by Using the Incubated Hen's Egg
Drug Res (Stuttg) 2015 Sep;65(9):500-4.PMID:25310250DOI:10.1055/s-0034-1390457.
Metabolism studies with selected test substances have shown that a model on the basis of the incubated hen's egg is suitable as a supplement to animal experimentation. Because of its 3,4-dimethoxyphenyl structure Veratric acid (3,4-Dimethoxybenzoic acid), a known human metabolite of mebeverine, was chosen as model substance for the present investigations and the parent compound as well as 4-hydroxy-3-methoxybenzoic acid were identified as main metabolites. The absence of 3-hydroxy-4-methoxybenzoic acid lets conclude that the O-demethylation takes place exclusively at the p-methoxyl function. In addition, 3,3',4,4'-tetramethoxy-l-ornithuric acid (2,5-bis-(3,4-dimethoxybenzoylamino)pentanoic acid) and its O-desmethyl derivative could be characterized as further metabolites. So far an amino acid conjugate has not been described after veratric acid administration in a vertebrate. There were no indications for the appearance of 3,4-dihydroxybenzoic acid in the veratric acid metabolism. This was confirmed by corresponding studies having the isomeric guaiacol acids as precursor. Furthermore, it could be proved that in ovo the O-methylation of 3,4-dihydroxybenzoic acid occurs regioselective at the m-hydroxyl group. The results which broaden the knowledge on the metabolic fate of veratric acid are discussed in comparison with those in mammals. The metabolites were identified by GC-MS, ESI-HRMS and LC/ESI-MS/MS. The structure of the synthesized reference substance was confirmed by MS, (1)H and (13)C NMR spectral data.
Antagonist effects of Veratric acid against UVB-induced cell damages
Molecules 2013 May 10;18(5):5405-19.PMID:23666007DOI:10.3390/molecules18055405.
Ultraviolet (UV) radiation induces DNA damage, oxidative stress, and inflammatory processes in human epidermis, resulting in inflammation, photoaging, and photocarcinogenesis. Adequate protection of skin against the harmful effect of UV irradiation is essential. In recent years naturally occurring herbal compounds such as phenolic acids, flavonoids, and high molecular weight polyphenols have gained considerable attention as beneficial protective agents. The simple phenolic Veratric acid (VA, 3,4-Dimethoxybenzoic acid) is one of the major benzoic acid derivatives from vegetables and fruits and it also occurs naturally in medicinal mushrooms which have been reported to have anti-inflammatory and anti-oxidant activities. However, it has rarely been applied in skin care. This study, therefore, aimed to explore the possible roles of Veratric acid in protection against UVB-induced damage in HaCaT cells. Results showed that Veratric acid can attenuate cyclobutane pyrimidine dimers (CPDs) formation, glutathione (GSH) depletion and apoptosis induced by UVB. Furthermore, Veratric acid had inhibitory effects on the UVB-induced release of the inflammatory mediators such as IL-6 and prostaglandin-E2. We also confirmed the safety and clinical efficacy of Veratric acid on human skin. Overall, results demonstrated significant benefits of Veratric acid on the protection of keratinocyte against UVB-induced injuries and suggested its potential use in skin photoprotection.
Formation and Action of Lignin-Modifying Enzymes in Cultures of Phlebia radiata Supplemented with Veratric acid
Appl Environ Microbiol 1990 Sep;56(9):2623-9.PMID:16348272DOI:10.1128/aem.56.9.2623-2629.1990.
Transformation of veratric (3,4-dimethoxybenzoic) acid by the white rot fungus Phlebia radiata was studied to elucidate the role of ligninolytic, reductive, and demeth(ox)ylating enzymes. Under both air and a 100% O(2) atmosphere, with nitrogen limitation and glucose as a carbon source, reducing activity resulted in the accumulation of veratryl alcohol in the medium. When the fungus was cultivated under air, Veratric acid caused a rapid increase in laccase (benzenediol:oxygen oxidoreductase; EC 1.10.3.2) production, which indicated that Veratric acid was first demethylated, thus providing phenolic compounds for laccase. After a rapid decline in laccase activity, elevated lignin peroxidase (ligninase) activity and manganese-dependent peroxidase production were detected simultaneously with extracellular release of methanol. This indicated apparent demethoxylation. When the fungus was cultivated under a continuous 100% O(2) flow and in the presence of Veratric acid, laccase production was markedly repressed, whereas production of lignin peroxidase and degradation of veratryl compounds were clearly enhanced. In all cultures, the increases in lignin peroxidase titers were directly related to veratryl alcohol accumulation. Evolution of CO(2) from 3-OCH(3)-and 4-OCH(3)-labeled veratric acids showed that the position of the methoxyl substituent in the aromatic ring only slightly affected demeth(ox)ylation activity. In both cases, more than 60% of the total C was converted to CO(2) under air in 4 weeks, and oxygen flux increased the degradation rate of the C-labeled veratric acids just as it did with unlabeled cultures.
A study of facial wrinkles improvement effect of Veratric acid from cauliflower mushroom through photo-protective mechanisms against UVB irradiation
Arch Dermatol Res 2016 Apr;308(3):183-92.PMID:26914455DOI:10.1007/s00403-016-1633-z.
Solar ultraviolet (UV) irradiation is a primary cause of premature skin aging that is closely associated with the degradation of collagens caused by up-regulation of matrix metalloproteinases (MMPs) or a decrease in collagen synthesis. The phenolic Veratric acid (VA, 3,4-Dimethoxybenzoic acid) is one of the major benzoic acid derivatives from fruits, vegetables and medicinal mushrooms. VA has been reported to have anti-inflammatory, anti-oxidant and photo-protective effects. In this study, anti-photoaging effects were investigated through the photo-protective mechanisms of VA against UV irradiation in human dermal fibroblasts and the reconstructed human epidermal model. We used reverse transcription-polymerase chain reaction, Western blot analysis, hematoxylin and eosin staining (H&E) and immunohistochemistry assays. Finally, we further investigated the clinical effects of VA on facial wrinkle improvements in humans. Our results demonstrate that VA attenuated the expression of MMPs, increased cell proliferation, type Ι procollagen, tissue inhibitors of metalloproteinases, and filaggrin against UV radiation; however, has no effect on improvement expressions of elastic fiber. In addition, treatment with cream containing VA improved facial wrinkles in a clinical trial. These findings indicate that VA improves wrinkle formation by modulating MMPs, collagens and epidermal layer integrity, suggesting its potential use in UV-induced premature skin aging.
Aerobic and Anaerobic Catabolism of Vanillic Acid and Some Other Methoxy-Aromatic Compounds by Pseudomonas sp. Strain PN-1
Appl Environ Microbiol 1983 Dec;46(6):1286-92.PMID:16346441DOI:10.1128/aem.46.6.1286-1292.1983.
Vanillic acid (4-hydroxy-3-methoxybenzoic acid) supported the anaerobic (nitrate respiration) but not the aerobic growth of Pseudomonas sp. strain PN-1. Cells grown anaerobically on vanillate oxidized vanillate, p-hydroxybenzoate, and protocatechuic acid (3,4-dihydroxybenzoic acid) with O(2) or nitrate. Veratric acid (3,4-Dimethoxybenzoic acid) but not isovanillic acid (3-hydroxy-4-methoxybenzoic acid) induced cells for the oxic and anoxic utilization of vanillate, and protocatechuate was detected as an intermediate of vanillate breakdown under either condition. Aerobic catabolism of protocatechuate proceeded via 4,5-meta cleavage, whereas anaerobically it was probably dehydroxylated to benzoic acid. Formaldehyde was identified as a product of aerobic demethylation, indicating a monooxygenase mechanism, but was not detected during anaerobic demethylation. The aerobic and anaerobic systems had similar but not identical substrate specificities. Both utilized m-anisic acid (3-methoxybenzoic acid) and veratrate but not o- or p-anisate and isovanillate. Syringic acid (4-hydroxy-3,5-dimethoxybenzoic acid), 3-O-methylgallic acid (3-methoxy-4,5-dihydroxybenzoic acid), and 3,5-dimethoxybenzoic acid were attacked under either condition, and formaldehyde was liberated from these substrates in the presence of O(2). The anaerobic demethylating system but not the aerobic enzyme was also active upon guaiacol (2-methoxyphenol), ferulic acid (3-[4-hydroxy-3-methoxyphenyl]-2-propenoic acid), 3,4,5-trimethoxycinnamic acid (3-[3,4,5-trimethoxyphenyl]-2-propenoic acid), and 3,4,5-trimethoxybenzoic acid. The broad specificity of the anaerobic demethylation system suggests that it probably is significant in the degradation of lignoaromatic molecules in anaerobic environments.
