Quinone—amine polymers: 10. Use of calcium hypochlorite in the syntheses of polyamine—quinone (PAQ) polymers

Simultaneous measurement of cholinergic tone and neuronal network dynamics in vivo in the rat brain using a novel choline oxidase based electrochemical biosensor

“…Primary amine groups from chitosan and protein molecules can easily undergo nucleophilic reactions with unsubstituted quinones (e. g. pbenzoquinone) eventually forming covalent links between amine groups (Nithianandam and Erhan, 1991;Park et al, 2000;Wang et al, 2011;Yang et al, 2009). As a result, it is expectable that the reactions of pbenzoquinone with amine groups from chitosan and protein molecules yield a crosslinked network containing combinations of chitosan-chitosan, protein-chitosan and protein-protein bonds.…”

Electrochemical synthesis of amino-substituted 1,2-benzoquinone derivatives

“…In addition, many drugs, such as doxorubicin, daunorubicin and mitomycin C in cancer chemotherapy contain quinones [5], whereas various other quinones have found uses in industry [6,7]. In particular, alkylamino derivatives of quinones are of considerable interest because they exhibit antitumor and antimalarial activities [8][9][10] and many of them are also involved in enzyme inhibition and DNA cross-linking [11].…”

Use of bis-aminoalcohol benzoquinones and dihydroxybenzoquinones in the formation of mono and polymeric structures of diorganotin(IV) derivatives

“…The elevated electron density allows for a strong interaction with metal surfaces such as steel, capable of protecting the metal surface from corrosion. In particular poly(aminoquinones) (PAQs) provide excellent anticorrosive coatings for metal surfaces [8]. It is also worthwhile to mention that the 1,4-benzoquinone moiety forms part of the structural skeleton of mitomycin C, an antibiotic that also presents anticancer activity [9].…”
