At neutral pH, 1,4-naphthohydroquinone and 2-methyl-1,4-naphthohydroquinone readily autoxidize to the corresponding quinones. In an unpurified phosphate buffer, the autoxidation of both substances proceeded in a linear fashion after a brief lag phase. Addition of a chelating agent or purification of

Free radical research, 32(3), 245-253 (2000-03-24)
The rates of autoxidation of a number of pure naphthohydroquinones have been determined, and the effects of pH, superoxide dismutase (SOD) and of the parent naphthoquinone on the oxidation rates have been investigated. Most compounds were slowly oxidised in acid

The proteases encoded by herpesviruses including herpes simplex virus type 1 (HSV-1) and human cytomegalovirus (HCMV) are attractive targets for antiviral drug development because of their important roles in viral replication. We randomly screened a chemical compound library for inhibitory

The autoxidation of 1,4-naphthohydroquinone, in a phosphate, EDTA buffer at pH 7.4, exhibits an autocatalysis whose lag phase becomes more pronounced in the presence of either the Cu,Zn- or the Mn-containing superoxide dismutases. In contrast, the autoxidation of a second

Several new 6-(3-pyrazolylpropyl) derivatives of 1,4-naphthohydroquinone-1,4-diacetate (NHQ-DA) have been prepared by chemical modifications of the Diels-Alder adduct of alpha-myrcene and 1,4-benzoquinone. All these new compounds and precursors have been evaluated in vitro for their cytotoxicity against cultured human cancer cells
