pyrogallol

(pī″rō-găl′ōl″)
C6H6O3; a toxic chemical derived from gallic acid.

pyrogallol

; pyrogallic acid non-self-limiting, topical, keratolytic/caustic organic acid (also destroys fine nerve endings in skin); formerly used to treat verrucae; application causes a dense black skin stain; prepared as 40% paste in white soft paraffin (WSP) (pyrogallol ointment), or as 20% ointment with 20% wheat germ oil in WSP (WP ointment); Caution: it should be used with caution, i.e. on healthy feet, to a maximum of three consecutive applications, and never on patients with peripheral vascular disease, neuropathy or any other form of reduced tissue viability or compromised healing (e.g. diabetes); can cause haemolysis if applied to wide areas of skin

This is clearly illustrated by the structure determination of pyrogallol HMTA (1/1), in which despite the presence of two entirely different molecular components in the structure, and the evidence of preferred orientation in the data, structure solution and refinement ran smoothly.
Gallic acid, pyrogallol, homogentisic acid, protocatechuic acid, (+) catechin, chlorogenic acid, caffeic acid, vanillin, ferulic acid, naringin, resveratrol, naringenin, hesperetin, formononetin and biochanin-A were used as standard for the detection of phenolic compounds from the fruiting bodies of P.
The activity of the isolated laccase toward other substrates including ABTS, N,N-dimethyl-1,4-phenylenediamine, hydroquinone, catechol, 2-methylcatechol, pyrogallol, and tyrosine was also tested.
The phenolic compounds, found in water extract of green parts of Glycine hispida, are pyrogallol and phenolic acids.
We investigated the effect of hemolysis on Pyrogallol Red (PYR) (2), benzethonium chloride (BTC) (3), and benzalkonium chloride (BC) (4) methods for measurement of protein.
More detailed structure-activity investigations are invited to address the interplay of galloyl and pyrogallol moieties, as well as further studies on structural and stereochemical prerequisites for cannabinoid signaling.
REACTIVITY OF DIFFERENT PROTEINS AND POLYPEPTIDES IN ENDPOINT AND KINETIC BIURET METHODS AND A PYROGALLOL RED METHOD
The determination of superoxide dismutase (SOD) activity was based on the inhibition of pyrogallol autooxidation (Misra and Fridovich 1972).
2001), porcine retinal homogenate oxidation accelerated by ferric ion (Hiramitsu and Armstrong, 1991), pyrogallol autaoxidation (Kim and Godber, 2001) and pharmaceutical oils (Juliano et al.
Pyrogallol is produced as one of the metabolite of gallic acid, but in this study pyrogallol was also not detected.
Total SOD activity was assayed as the inhibition of the autooxidation of pyrogallol in alkaline solution monitored at 420 nm (20), with 1 U of activity giving 50% inhibition at 10 min.
