Efficient photochemical activity and strong dichroism of single crystals of reaction centers from Rhodopseudomonas viridis [PDF]

open access: yes, 1983
Crystallized reaction centers from Rhodopseudomonas viridis (i) are photochemically active with electron transfer from the special pair to the quinones, (ii) show dichroism giving valuable information on the orientation of the different chromophores and (

Electrochemistry of potentially bioreductive alkylating quinones : Part 1. Electrochemical properties of relatively simple quinones, as model compounds of mitomycin- and aziridinylquinone-type antitumour agents [PDF]

open access: yes, 1990
The influence of methyl-, hydroxy and amino substituents on the electrochemical behaviour of simple 1,4-naphtho-and 1,4-benzoquinones, model compounds of many quinoid antitumour agents, in aqueous media was studied. Significant changes in electrochemical

Why 1,2‑quinone derivatives are more stable than their 2,3‑analogues? [PDF]

open access: yes, 2015
In this work, we have studied the relative stability of 1,2- and 2,3-quinones. While 1,2-quinones have a closed-shell singlet ground state, the ground state for the studied 2,3-isomers is open-shell singlet, except for 2,3-naphthaquinone that has a ...

Electrochemistry of potential bioreductive alkylating quinones : Part 2. Electrochemical properties of 2,5-bis(1-aziridinyl)-3,6-bis(ethoxycarbonylamino)-1,4-benzoquinone and some model compounds [PDF]

open access: yes, 1990
The reduction mechanism of 2,5-bis(1-aziridinyl)-3,6-bis(ethoxycarbonylamino)-1,4-benzoquinone (Diaziquone, AZQ) and several model compounds of the mono- and bis(1-aziridinyl)quinone type at the dropping mercury electrode in aqueous solutions was studied.
