Effect of Xanthone and 1-Hydroxy Xanthone on the Dipole Potential of Lipid Membranes

Colloid and Interface Science Communications, 2018
Abstract Xanthone (Xa) and 1-OH Xanthone (1-OHXa) in 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) membranes increase the dipole potential. Results with 1,2-di-O-tetradecyl-sn-glycero-3-phosphocholine (Ether PC), lacking carbonyl groups, indicate that the CO dipole of Xa molecule does not contribute to the increase of dipole potential.

ANTIOXIDANT ACTIVITY OF XANTHONE DERIVATIVES.

Acta poloniae pharmaceutica, 2016
Certain xanthone derivatives, such as these present in mangosteen fruits, show strong antioxidant activity. On the other hand, evidences accumulated that oxidative stress is involved in epileptogenesis. Therefore, the aim of the present study was to estimate total antioxidant capacity (expressed as a ferric reducing antioxidant power - FRAP) and ...

Determinação da constante de velocidade absoluta para a reação de abstração de hidrogênio fenólico pelo estado excitado triplete de xantona em acetonitrila e no líquido iônico hexafluorfosfato de 1-butil-3-metil-imidazólio [bmim.PF6] Determination of absolute rate constant for the phenolic hydrogen abstraction reaction by the triplet excited state of xanthone in acetonitrile and in ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate [bmim.PF6]

Química Nova, 2013
The triplet excited state of xanthone was generated and characterized by laser flash photolysis in acetonitrile (λmax=620 nm; t=1.8 ms) and in ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate [bmim.PF6] (λmax=620 nm; t=3.0 ms).
