Disease relevance of NSC6211


High impact information on NSC6211

  • The tolerance of PSII to photoinhibition in the autotrophic mutant DeltaR225-F239 (PD), when oxygen evolution was monitored with 2,6-dichloro-p-benzoquinone and the equal susceptibility compared with control when monitored with bicarbonate, suggested an inactivation of the QB-binding niche as the first event in the photoinhibition cascade in vivo [2].
  • The electron transfer sites of p-benzoquinone (pBQ) and 2,6-dichloro-p-benzoquinone (DCBQ) were investigated in thylakoid membranes and isolated photosystem II (PSII) particles from barley (Hordeum vulgare) using alpha- and beta-cyclodextrins (CD) at concentrations up to 16mM [3].
  • The charge transfer (CT) reaction between salbutamol as electron donor and 2,6-dichloroquinone chlorimide (DCQ) and 7,7,8,8-tetracyanoquinodimethane (TCNQ) as a pi-electron acceptor have been spectrophotometrically studied [4].
  • A single major product was detected by reverse phase HPLC and was identified as 2,6-dichloro-1,4-benzoquinone (2,6-dichloro-2, 5-cyclohexadiene-1,4-dione, CAS no. 697-91-6) on the basis of electronic absorption spectroscopy, mass spectrometry, and cochromatography with synthetic standard [5].
