21384152-9	2012	Results from spectroscopy assays indicate that HT in the presence of peroxidases can undergo catechol-semiquinone-quinone redox cycling generating superoxide, which in a cellular context can activate the antioxidant system, e.g., MnSOD expression.	quinone	106-113	superoxide dismutase 2	Homo sapiens	230-235	
8643079-8	1996	In phosphate-buffered saline (PSB), HQ underwent a slow autoxidation to BQ, which was accelerated by Cu/Zn-SOD, Mn-SOD, or Fe-SOD with similar efficiency.	quinone	72-74	superoxide dismutase 2	Homo sapiens	112-118
