catechol

Guaiacol Market is industrially manufactured by the methylation of catechol and is used in the manufacturing of a variety of chemical products.

This might cause an increase in the secretion of the glucocorticoids, catechol amines, and the inflammatory cytokines.

The 3,4-dihydroxyphenyl (catechol) substructure in L-DOPA is presumed to be produced by enzymatic hydroxylation of tyrosine (Waite, 1983; Zhao et al., 2005) via a tyrosinase (Guerette et al., 2013).

This sequence implies anticholinergics first, then amantadine, dopaminergic agonists, monoamine oxidase-B (MAO-B), catechol O-methyltransferase (COMT) and eventually levodopa.

The first step in the aerobic degradation pathway is oxidative deamination with the production of catechol, with further degradation to cis, cis-muconic acid by the catechol 1,2-dioxygenase (ortho-cleavage pathway) (Aoki et al., 1984; Loidl et al., 1990; Murakami et al., 2003) or to a yellow compound, 2-hydroxymuconic semialdehyde by catechol 2,3-dioxygenase (the meta-cleavage pathway)(Fujii et al., 1997; Takeo et al., 1998a; Takeo et al., 1998b).

Acute cerebro-vascular disease may lead to cardiac arrhythmias and ECG abnormalities as a result of increased sympathetic nervous system activity and secretion of endogenous catechol amines, causing pulmonary edema and myocardial damage (4).

Dow introduced a non-phthalate catalyst with a catechol dibenzoate internal donor in 2011, called Consista, with so much higher activity and isotacticity that Dow called it 6th generation.

Catechol (1,2-dihydroxybenze, CT) and hydroquinone (1,4-dihydroxybenze, HQ) are two dihydroxybenzene isomers that occur naturally in many plant foods (onions, coffee, tea leaves, etc.) and beverages such as wines [1].

Synthesis and Characterization of Catechol Aldehyde (2).

This work presents the results concerning the spectrophotometric study of laccase from Trametes versicolor with three different substrates (caffeic acid, gallic acid, and catechol), evaluating their activity and inhibition degrees in the presence of mercury(II), and observing that millimolar mercury concentrations can reduce the laccase reaction extent.

In order to determine enzyme activity, 3 ml of catechol 0.05M, 75ml of enzyme extract and 75[micro]l of the chemical inhibitor were placed into a 4ml quartz cell.

Researchers at UCSB developed the material in which molecular bonds between iron and an organic compound called catechol allow for it to be stretchy, but difficult to break.
