In this case, guaiacol should be attacked by an O-demethylase, a monooxygenase removing the methyl group in the form of formaldehyde. This type of mechanism has already been proved in several instances [13,14]. Phenolic compounds are widely used in clinical dentistry as sedatives for the dental pulp, as disinfectants for caries, and as root canal medications. The pathobiological effects of various phenolic compounds on human dental pulp fibroblasts were investigated with Hoechst 33258 fluorescence assay an … Guaiacol Accession Number DB11359 Description. Guaiacol is an agent thought to have disinfectant properties and used as an expectorant. Guaiacol is a phenolic natural product first isolated from Guaiac resin and the oxidation of lignin.

Guaiacol was officially classified in the Regulation (EC) n°1272/2008 Annex VI table 3 and was not classified for acute toxicity by inhalation. Information on Registered Substances comes from registration dossiers which have been assigned a registration number. At a concentration higher than 3 mM, eugenol was cytotoxic to human oral mucous membrane cells, decreasing both cellular ATP and glutathione. However, at less than 1 mM, eugenol protected cells from the genetic attack of ROS, in part by inhibiting lipid peroxidation ( Jeng et al 1994a ).

Guaiacol is an agent thought to have disinfectant properties and used as an expectorant. Guaiacol is a phenolic natural product first isolated from Guaiac resin and the oxidation of lignin. Guaiacol is also present in wood smoke, as a product of pyrolysis of lignin. 2015-03-09 · Aromatic compounds contribute significantly to the budget of atmospheric pollutants and represent considerable hazard to living organisms.

An estimated 85% of the world's supply of vanillin comes from guaiacol. The route entails condensation of glyoxylic acid with guaiacol to give mandelic acid, which is oxidized to produce a phenylglyoxylic acid. This acid undergoes a decarboxylation to afford vanillin.
