Antibiotic-Resistant Staphylococcus aureus Does Not Develop Resistance to Vanillic Acid and 2-Hydroxycinnamic acid after Continuous Exposure in Vitro
ACS Omega 2019 Sep 10;4(13):15393-15400.PMID:31572838DOI:10.1021/acsomega.9b01336.
Development of resistance to antibiotics is one of the major reasons of difficulties in treatments of diseases caused by antibiotic-resistant bacteria, and this resistance makes the investigation of alternative antimicrobials a key priority. Phenolic acids are plant- and fungi-originating natural antimicrobial products, and there is no known bacterial resistance after exposure to them. The purpose of this study was to investigate the resistance ability of bacteria against phenolic acids. Therefore, the ability of methicillin-resistant Staphylococcus aureus and methicillin-susceptible S. aureus to gain resistance against two phenolic acids and an antibiotic upon exposure to subinhibitory concentrations was tested. Herein, we evaluated the minimum inhibitory concentrations (MICs) of vanillic acid (VA), 2-Hydroxycinnamic acid (2-HCA), and vancomycin in the beginning of the experiment and the MICs were found to be 2.5 mg/mL VA, 1.6 mg/mL 2-HCA, and 0.01 mg/mL vancomycin for both bacteria. Following continuous treatments with increasing subinhibitory concentrations, MICs were evaluated once more. Exposure to subinhibitory concentrations of vancomycin induced the development of resistance immediately; however, resistance to both phenolic acids could not be induced. These data indicated the potential of phenolic acids to be used as effective antimicrobials in the inhibition of antibiotic-resistant pathogenic bacteria.
Hydroxycinnamic Acid from Corncob and Its Structural Analogues Inhibit Aβ40 Fibrillation and Attenuate Aβ40-Induced Cytotoxicity
J Agric Food Chem 2020 Aug 19;68(33):8788-8796.PMID:32700906DOI:10.1021/acs.jafc.0c01841.
The aggregation of amyloid-β protein (Aβ) is deemed a vital pathological feature of Alzheimer's disease (AD). Hence, inhibiting Aβ aggregation is noticed as a major tactic for the prevention and therapy of AD. Hydroxycinnamic acid, as a natural phenolic compound, is widely present in plant foods and has several biological activities including anti-inflammation, antioxidation, and neuroprotective effects. Here, it was found that hydroxycinnamic acid and its structural analogues (3-hydroxycinnamic acid, 2-Hydroxycinnamic acid, cinnamic acid, 3,4-dihydroxycinnamic acid, 2,4-dihydroxycinnamic acid, and 3,4,5-trihydroxycinnamic acid) could inhibit Aβ40 fibrillogenesis and reduce Aβ40-induced cytotoxicity in a dose-dependent manner. Among these small molecules investigated, 3,4,5-trihydroxycinnamic acid is considered to be the most effective inhibitor, which reduces the ThT fluorescence intensity to 30.79% and increases cell viability from 49.47 to 84.78% at 200 μM. Also, the results with Caenorhabditis elegans verified that these small molecules can ameliorate AD-like symptoms of worm paralysis. Moreover, molecular docking studies showed that these small molecules interact with the Aβ40 mainly via hydrogen bonding. These results suggest that hydroxycinnamic acid and its structural analogues could inhibit Aβ40 fibrillogenesis and the inhibition activity is enhanced with the increase of phenolic hydroxyl groups of inhibitors. These small molecules have huge potential to be developed into novel aggregation inhibitors in neurodegenerative disorders.
Catalysis and inhibition of tyrosinase in the presence of cinnamic acid and some of its derivatives
Int J Biol Macromol 2018 Nov;119:548-554.PMID:30063931DOI:10.1016/j.ijbiomac.2018.07.173.
The kinetic action of tyrosinase on l-tyrosine and l-Dopa as substrates in the presence of cinnamic acid and some of its derivatives has been characterized. Cinnamic acid, 2-hydroxycinnamic, 2,3 and 4-methoxycinnamic acids were seen to be inhibitors of tyrosinase being determined the type of inhibition and inhibition constants of all of them. However, 3-hydroxycinnamic, 4-hydroxycinnamic and 3,4-dihydroxycinnamic acids were seen to be substrates of tyrosinase at the same time. The kinetic constants of the catalysis of these substrates were determined and found to be perfectly correlated with the chemical shifts of the carbon with the phenolic hydroxyl group revealed by NMR. Docking studies of 2-hydroxycinnamic and 3-hydroxycinnamic acids showed that tyrosinase is able to hydroxylate 3-hydroxycinnamic acid but is unable to hydroxylate 2-Hydroxycinnamic acid.
Chemical Composition, Antioxidant Activity, Cytoprotective and In Silico Study of Ethanolic Extracts of Bougainvillea × buttiana (Var. Orange and Rose)
Molecules 2022 Oct 3;27(19):6555.PMID:36235092DOI:10.3390/molecules27196555.
Bougainvillea × buttiana is a plant widely used in traditional Mexican medicine and other parts of the world for the treatment of various health disorders. In this study, the antioxidant and cytoprotective activities of three ethanolic extracts of B. × buttiana (BxbO (Orange), BxbR1 (Rose1) and BxbR2 (Rose2)) were investigated. Antioxidant activities were determined by the oxygen radical absorbance capacity (ORAC), DPPH free radicals scavenging activity, and radical scavenging effects on nitric oxide (NO). The in vitro cytoprotective effect of the extracts against oxidative stress induced by hydrogen peroxide-(H2O2) in a model of L929 cells was also determined as well as NO uptake with or without H2O2 through the MTT assay. The results revealed that there was a difference between the compounds present in each of the extracts, with the 2-Hydroxycinnamic acid compound being observed in all the extracts. The 2-Hydroxycinnamic acid compound was tested in silico to predict its biological (PASSonline) and toxicological (Osiris Property Explorer) activity. All extracts with 1 to 4 mg/mL inhibited the activity of the NO radical. In cells exposed to 1 mg/mL of extracts followed by H2O2 exposure, cell protection ranged from 66.96 to 83.46%. The treatment of the cells with extracts prevented the morphological changes caused by H2O2. The 2-Hydroxycinnamic acid compound showed a probability of in silico antioxidant and cytoprotective activity greater than 0.5 and 0.6, respectively. Therefore, the results demonstrated that Bxb extracts exert antioxidant and protective activities against H2O2-induced oxidative stress in L929 cells.
Unraveling the Serum Metabolomic Profile of Acrylamide-Induced Cardiovascular Toxicity
J Agric Food Chem 2021 Oct 13;69(40):12012-12020.PMID:34586797DOI:10.1021/acs.jafc.1c04367.
Acrylamide has been reported as an important dietary risk factor from carbohydrate-rich processing food. However, systemic biological effects on the serum metabolomics induced by acrylamide have poorly been understood. In the present study, we evaluated the metabolic profiles in a rat serum after exposure to acrylamide using ultrahigh-performance liquid chromatography combined with quadrupole-orbitrap high-resolution mass spectrometry. The serum biochemical parameters of the treated and control groups were also determined using an automatic biochemical analyzer. Compared with the control group, 10 metabolites were significantly upregulated, including citric acid, d-(-)-fructose, gluconic acid, l-ascorbic acid 2-sulfate, 2-Hydroxycinnamic acid, valine, l-phenylalanine, prolylleucine, succinic acid, and cholic acid, while 5 metabolites were significantly downregulated, including 3-hydroxybutyric acid, 4-oxoproline, 2,6-xylidine, 4-phenyl-3-buten-2-one, and N-ethyl-N-methylcathinone in the serum of 4-week-old rats exposed to acrylamide in the high-dose group (all P < 0.05). Importantly, acrylamide exposure affected metabolites mainly involved in the citrate cycle, valine, leucine, and isoleucine biosyntheses, phenylalanine, tyrosine and tryptophan biosyntheses, and pyruvate metabolism. These results suggested that exposure to acrylamide in rats exhibited marked systemic metabolic changes and affected the cardiovascular system. This study will provide a theoretical basis for exploring the toxic mechanism and will contribute to the diagnosis and prevention of acrylamide-induced cardiovascular toxicity.
