1) corresponds to arthropods that cluster in part because they utilize quinones--most notably 1,4-benzoquinone, 2-methyl-1,4-benzoquinone, and 2-methoxy-3-methyl-l,4-benzoquinone (Fig.

2] is prepared by coating silica gel with ceric ammonium nitrate and is used to oxidize hydroquinones to their corresponding 1,4-benzoquinone.
Because epidemiological studies of HQ and 1,4-benzoquinone have never demonstrated carcinogenicity in humans, the International Agency for Research on Cancer (IARC) assigned their carcinogenic risk to humans as group 3: not classifiable as to carcinogenicity to humans (IARC 2011).
In a previous communication we showed that atrovirinone, a 1,4-benzoquinone isolated from the roots of Garcinia atroviridis, was able to inhibit several major proinflammatory mediators of inflammation.

The commonly used inhibitors and retarders for the free radical reaction include 1,4-benzoquinone, hydroquinone, catechol, etc.
This is especially important because hydroquinone is the precursor of 1,4-benzoquinone, which is generally regarded as the most hematotoxic metabolite of benzene (Kim et al.
