Myricetin, a bioactive plant flavonol, readily forms inclusion complex with the drug delivery vehicle beta-cyclodextrin (β-CD). Appearance of typical "dual emission", consisting of normal (470 nm) and ESIPT tautomer (530 nm) bands, with concomitant rise in fluorescence intensity and dramatically
The in vitro formation of quercetin- and myricetin-cyclodextrin inclusion complexes in acidic medium has been characterized using the enzymatic system horseradish peroxidase, which oxidizes those flavonols in the presence of H2O2. The presence of cyclodextrins (CDs) in the reaction medium inhibited
The interaction mechanism of flavonol myricetin (3,5,7,3',4',5'-hexahydroxyflavone) and human serum albumin (HSA) has been characterized by fluorescence, electronic absorption, and Fourier transform infrared (FT-IR) spectroscopic approaches and the molecular modeling method. The structural
BACE1 is a key protease involved in the proteolysis of amyloid precursor protein (APP) that generates a toxic peptide amyloid beta (Aβ), a pathological feature of Alzheimer's disease (AD). The enzyme is believed to possess an open and a closed conformation that corresponds to its free and
BACKGROUND
Dental caries is considered a multifactorial disease, in which microorganisms play an important role. The diet is decisive in the biofilm formation because it provides the necessary resources for cellular growth and exopolysaccharides synthesis. Exopolysaccharides are the main components
Four cyclodextrins (CD) including β-cyclodextrin (β-CD), γ-cyclodextrin (γ-CD), heptakis-O-(2-hydroxypropyl)-β-cyclodextrin (HP-β-CD), and heptakis-O-(2, 6-di-O-methyl)-β-cyclodextrin (DM-β-CD) were used as solubilizer to study the solubility enhancement of myricetin. The
The mouth cavity hosts many types of anaerobic bacteria, including Streptococcus mutans and Porphyromonas gingivalis, which cause periodontal inflammatory diseases and dental caries. The present study was conducted to evaluate the antibacterial potential of extracts of Robinia pseudoacacia and its
BACKGROUND
Some species of Campomanesia are used in the folk medicine due to anti-inflammatory, anti-diarrheal, anti-diabetes and hypercholesterolemic. However studies with Campomanesia guazumifolia (Cambess.) O. Berg. are scarce.
OBJECTIVE
This study investigated the anti-inflammatory activity and
The cytotoxicities of the nitric oxide (NO) donors, S-nitroso-N-acetylpencillamine (SNAP) and three glyco-SNAPs, glucose-1-SNAP, glucose-2-SNAP, and fructose-1-SNAP, towards the human gingival epithelioid S-G cell line and three human carcinoma cell lines derived from tissues of the oral cavity were
In this study, the interaction between nine classic flavonoids (including baicalin, quercetin, myricetin, rutin, puerarin, daidzein, liquiritin and isoliquiritin) and trypsin was investigated by fluorescence spectroscopy and molecular modeling methods. The results reveal that all flavonoids can
BACKGROUND
Guava pomace is an example of the processing waste generated after the manufacturing process from the juice industry that could be a source of bioactives. Thus, the present investigation was carried out in order to evaluate the anti-inflammatory and antinociceptive potential and
Accidents involving snakes from the genus Bothrops sp. constitute the most important cause of snake envenomation in Brazil. The Myrsine genus has been reported to be used in folk medicine against snakebites. In this work, the phytochemical profiles and ability of extracts from Myrsine parvifolia
Dental caries is a multi-factorial oral disease, requiring a susceptible host, cariogenic microorganisms and suitable substrate. Caries is extended worldwide in spite of the availability of countless prophylactic means, including fluoride toothpaste and dental sealers. Many efforts Dental caries is a diet-biofilm-dependent disease. Streptococcus mutans contributes to cariogenic biofilms by producing an extracellular matrix rich in exopolysaccharides and acids. The study aimed to determine the effect of topical treatments with compound 1771 (modulates lipoteichoic acid
Fluoride is the mainstay of dental caries prevention, and yet current applications offer incomplete protection and may not effectively address the infectious character of the disease. Therefore, we evaluated the effectiveness of a novel combination therapy (CT; 2 mM myricetin, 4 mM tt-farnesol, 250
