Kaempferol is a flavonoid that occurs in tea and many vegetables fruits, including broccoli, cabbage, beans, grapes, apples, strawberries. The efficacy of has been demonstrated the treatment breast, esophageal, cervical, ovarian, liver cancers leukemia, which very likely arises from its prooxidant properties activation pro-apoptotic pathways. Indeed, this matter already focus number published studies reviews. aim present study was to elucidate antioxidant vs. flavonoids presence redox-active...
The beneficial effects of polyphenols, predominantly in the context oxidative stress-related diseases such as cancer, cardiovascular and neurological conditions including Alzheimer's Parkinson's diseases, have been documented by a number papers reviews. antioxidant/prooxidant properties phenolic compounds are related mainly to positions hydroxyl groups their redox metal (Cu, Fe) chelating capacity. In this work we studied structurally distinct molecules myricetin, morin,...
The formation of interfacial charge transfer (ICT) complexes with suitable ligands is an effective method to improve the spectral properties materials based on titanium dioxide (TiO2). In presented work, six structurally different flavonoids are studied as potential for synthesizing novel TiO2‐based ICT using density functional theory (DFT). stable bidentate Ti‐O coordination between TiO2 surface and confirmed by Bader’s quantum atoms in molecules (QTAIM) analysis. calculated band gaps...
Flavonoids are a group of polyphenolic compounds known to possess good radical scavenging activity. It was also shown that their anti/prooxidant properties strongly structure‐dependent and can be modified by metal ion binding. The structural parameters appear key factors during DNA‐binding abilities. This work deals with spectroscopic theoretical studies two flavonoids, baicalein scutellarein, alone, in the presence redox‐active Cu(II). Cu(II) is catalytic active Fenton‐like reactions...
Reactions of non-steroidal anti-inflammatory drugs tolfenamic, meclofenamic, mefenamic, clonixic and niflumic acids with isonicotinamide copper(<sc>ii</sc>) acetate resulted in the formation five novel mixed-ligand Cu(<sc>ii</sc>) coordination compounds.
Abstract As people spend many hours looking at digital screens, the negative effects of artificial blue light are becoming more apparent. While most research has focused on its eyes, less is known about skin, where similar photoreceptors located. Unlike sunscreens against UVB and UVA radiation, there no standard method for determining skin protection light. The lipophilic complex Carotolino, a system combining carrot root extract, seed oil, β-carotene, was chosen as model substance this...
Abstract Cooper( ii ) complexes represent a promising group of compounds with antimicrobial and antifungal properties. In the present work, series Cu( containing non-steroidal anti-inflammatory drugs, tolfenamic acid, mefenamic acid flufenamic as their redox-cycling functionalities, 1,10-phenanthroline an intercalating component, has been studied. The antibacterial activities all three complexes, [Cu(tolf-O,O′) 2 (phen)] ( 1 ), [Cu(mef-O,O′) [Cu(fluf-O,O′) 3 were tested against prokaryotic...

Abstract Dimethyl sulfoxide (DMSO) is an aprotic organic solvent widely used in laboratory practice due to its ability dissolve both polar and nonpolar compounds. However, DMSO also commonly known as a strongly coordinating solvent, especially towards transition metal containing complexes. In this study, estimation of the coordination Cu(II) ion was attempted, employing model system composed 3′,4′-dihydroxyflavone-Cu(II) complex presence explicit molecules, using density functional theory...
The aim of this study was to explore the influence various n-propylamines (mono, di, and tri) tert-butylamine on properties prepared peroxo-titanates annealed TiO2. Detailed structural characterization (SEM, TEM with EDX, XRD) confirmed 2D-foil morphology TiO2 nanocrystals CHNS analysis together XPS showed presence carbon (under 1 wt%). excellent photocatalytic activity up four times higher decomposition rate constant upon UV irradiation than P25. Favourable growth crystals observed...
In this work, attention is focused on the non-essential amino acid L-Tyrosine (TYR) hydroxylated to L-DOPA, which precursor neurotransmitters dopamine, noradrenaline (norepinephrine; NE) and adrenaline (epinephrine; EP) known as catecholamines their interactions with redox-active Cu(II). Catecholamines have multiple functions in biological systems, including regulation of central nervous system, free (unbound) redox metal ions are present many diseases disturbed homeostasis. The interaction...
