Associations of Menadiol with other chemical compounds

  • These results show that menadione exerts an antioxidant effect through participation of microsomal DT-diaphorase by generating menadiol with a radical scavenging ability, while menadiol also has a prooxidant property [12].
  • The antioxidant activity of reduced menadione was investigated and compared with that of alpha-tocopherol both in solvent solution and in large unilamellar vesicles by using azocompounds as free radical generators [11].
  • An in vitro quinol dehydrogenase assay was developed to show that both NapG and NapH are essential for rapid electron transfer from menadiol to the terminal NapAB complex [13].

Analytical, diagnostic and therapeutic context of Menadiol

  • The synthesis and purification of menadiol diphosphate are described, and it was shown to be sufficiently stable for qualitative and semiquantitative histochemistry, as well as for the immunohistochemistry of enzymes and cytoskeletal proteins with nonspecific alkaline phosphatase as the enzyme label [10].
