Oxygen plays an important role in the metabolism of all tissues. The level of oxygen in the
environment of melanin biopolymer in human body may change toxic effects resulted from …

DOPA-melanin-dihydrostreptomycin complexes with drug concentrations 1× 10 ^-4-1× 10 ^-
2 M were examined by the use of electron paramagnetic resonance spectroscopy at X-band …

Paramagnetic complexes of DOPA–melanin with ciprofloxacin, lomefloxacin, norfloxacin
and sparfloxacin were studied by EPR spectroscopy. The aim of this work was to determine …

Drug binding by melanin biopolymers influence the effectiveness of the chemotherapy,
radiotherapy and photodynamic therapy. Free radicals of melanins take part in formation of …

Electron paramagnetic resonance (EPR) studies of complexes of chloroquine with melanin
synthesized from 3, 4-dihydroxyphenylalanine (DOPA) confirmed an important role of o …

Abstract Effect of UV irradiation on free radicals in different types of melanins and melanin
complexes with diamagnetic Cd (II) and paramagnetic Cu (II) was examined by the use of …

EPR studies pointed out that o-semiquinone free radicals with g-values 2.0038–2.0040 take
part in moxifloxacin–melanin complex formation. The process contributed to increase in free …

Melanins are polymorphous and multifunctional biopolymers with a relatively high
concentration of free radicals. EPR spectroscopy was used to study o-semiquinone free …

Electron paramagnetic resonance (EPR) spectroscopy was used to examine interactions
between molecules of oxygen O2 and free radicals of DOPA–melanin and its complexes …

Electron paramagnetic resonance (EPR) spectroscopy may be applied to examine
interactions of melanin with metal ions and drugs. In this work EPR method was used to …
