Back-electron transfer suppresses the periodic length dependence of DNA-mediated charge transport across adenine tracts [PDF]
, 2008 DNA-mediated charge transport (CT) is exquisitely sensitive to the integrity of the bridging π-stack and is characterized by a shallow distance dependence. These properties are obscured by poor coupling between the donor/acceptor pair and the DNA bridge,

Anthraquinone in Indonesian infusion tea: analysis by HPLC–UV and risk assessment
Chemical and Biological Technologies in Agriculture, 2019 Background Detection of anthraquinone in tea samples marketed in Europe is raising a concern due to the possible carcinogenicity of this compound. The European Union has set a very low maximum residue level (MRL) for anthraquinone residue in tea (0.02 mg/

DNA intercalation and cleavage of an antitumor antibiotic dynemicin that contains anthracycline and enediyne cores [PDF]
, 1990 Dynemicin is a hybrid containing anthraquinone and enediyne cores, which contribute to binding and cleavage of DNA, respectively. DNA strand scission by the antitumor antibiotic is significantly enhanced by the addition of NADPH or thiol compounds.

Electrochemical control of quantum interference in anthraquinone-based molecular switches [PDF]
, 2010 Using first-principles calculations we analyze the electronic transport properties of a recently proposed anthraquinone based electrochemical switch. Robust conductance on/off ratios of several orders of magnitude are observed due to destructive quantum ...

Anthracene and Anthraquinone [PDF]
Nature, 1921 THE history of anthracene is long and vivid. Discovered amongst the products of coal-tar distillation in 1832, the hydrocarbon played a modest and somewhat commonplace part in the development of structural theory, suddenly blossoming into prominence in 1868, when it was found that alizarin, the twin monarch with indigo of natural colouring matters, is ...

Fungal Bioactive Anthraquinones and Analogues [PDF]
Toxins, 2020 This review, covering the literature from 1966 to the present (2020), describes naturally occurring fungal bioactive anthraquinones and analogues biosynthesized by the acetate route and concerning several different functionalized carbon skeletons. Hydrocarbons, lipids, sterols, esters, fatty acids, derivatives of amino acids, and aromatic compounds are
