Redox behaviour of the iron(III) complex with the antitumour drug hydroxyurea was studied by cyclic voltammetry. The complex underwent a one-electron reduction, followed by an irreversible chemical reaction (EC mechanism) in which a ligand was releas

Products and reaction stoichiometry of the interaction between iron(III) and hydroxyurea (HU) in aqueous solutions were studied. Under condition of an excess of iron(111) over hydroxyurea, initially formed mono(hydroxyurea)iron(III) complex decompose

ENDOR spectroscopy was used for the analysis of radiation-induced electron-loss radicals in thiocytosine. The radicals were induced by X-irradiating single crystals of cytosine monohydrate, substitutionally doped with 2-thiocytosine. X-irradiation an

It has been demonstrated that the paramagnetic species formed in crystals of cytosine hydrochloride doped with thiocytosine are most likely the radicals formed by association of thiocytosine and chlorine. The unpaired electron is positively identifie

Thioanalogs of the nucleic-acid bases are known photosensitive probes and good traps of radiation energy. Radiation-induced sulfur-centered free radicals stabilized on the base thioanalogs molecules are of the cationic origin. Their electronic config
