Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 533-73-3, formula is C6H6O3, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Product Details of C6H6O3
Groleau, Marie-Christine;Taillefer, Helene;Vincent, Antony T.;Constant, Philippe;Deziel, Eric research published 《 Pseudomonas aeruginosa isolates defective in function of the LasR quorum sensing regulator are frequent in diverse environmental niches》, the research content is summarized as follows. The saprophyte Pseudomonas aeruginosa is a versatile opportunistic pathogen causing infections in immunocompromised individuals. To facilitate its adaptation to a large variety of niches, this bacterium exploits population d.-dependent gene regulation systems called quorum sensing (QS). In P. aeruginosa, three distinct but interrelated QS systems (las, rhl and pqs) regulate the production of many survival and virulence functions. In prototypical strains, the las system, through its transcriptional regulator LasR, is important for the full activation of the rhl and pqs systems. Still, LasR-deficient isolates have been reported, mostly sampled from the lungs of people with cystic fibrosis, where they are considered selected by the chronic infection environment. In this study, we show that a defect in LasR activity appears to be an actually widespread mechanism of adaptation in this bacterium. Indeed, we found abundant LasR-defective isolates sampled from hydrocarbon-contaminated soils, hospital sink drains and meat/fish market environments, using an approach based on phenotypic profiling, supported by gene sequencing. Interestingly, several LasR-defective isolates maintain an active rhl system or are deficient in pqs system signalling. The high prevalence of a LasR-defective phenotype among environmental P. aeruginosa isolates questions the role of QS in niche adaptation.
533-73-3, Benzene-1, 2, 4-triol, also known as hydroxyhydroquinone or 1, 2, 4-benzenetriol, belongs to the class of organic compounds known as hydroxyquinols and derivatives. Hydroxyquinols and derivatives are compounds containing a 1, 2, 4-trihydroxybenzene moiety. Benzene-1, 2, 4-triol is soluble (in water) and a very weakly acidic compound (based on its pKa). Outside of the human body, benzene-1, 2, 4-triol can be found in tea. This makes benzene-1, 2, 4-triol a potential biomarker for the consumption of this food product.
Benzene-1,2,4-triol is a benzenetriol carrying hydroxy groups at positions 1, 2 and 4. It has a role as a mouse metabolite.
1,2,4-Benzenetriol is a metabolite of benzene.
1,2,4-Benzenetriol is an intermediary metabolite of benzene that is present in roasted coffee beans. It is mutagenic and it causes cleaving of DNA single strands by the generation of reactive oxygen species.
1,2,4-Benzenetriol is a reactive molecule that has been shown to have hydrogen bonding interactions with copper chloride. It has been proposed as an inhibitor of methyltransferase, which is involved in the synthesis of methionine. Studies have shown that 1,2,4-Benzenetriol can also inhibit iron homeostasis and transfer reactions. The x-ray diffraction data for this compound shows that it forms a complex with the hydroxyl group. This complex is stabilized by hydrogen bonding interactions with the hydroxylic proton of the 1,2,4-benzenetriol molecule. 1,2,4-Benzenetriol has been shown to be toxic to HL-60 cells and K562 cells at concentrations greater than 5 mM. It has also been found to be effective against chlorogenic acids and other compounds in energy metabolism studies at concentrations between 0.5 and 2 mM., Product Details of C6H6O3
