Hydroxyketone chelators, deferiprone (HK1), maltol (HK3) and their related compounds (HK2, 4-8), were characterized for their cytotoxic profiles against oral human normal and tumor cells. Most hydroxyketones except HK6 showed relatively higher tumor-specific cytotoxicity. Deferiprone (HK1), which
Organometallic ruthenium-arene compounds bearing a maltol ligand have been shown to be nearly inactive in in vitro anticancer assays, presumably due to the formation of dimeric Ru(II) species in aqueous solutions. In an attempt to stabilize such complexes, [Ru(eta(6)-p-cymene)(XY)Cl] (XY=pyrones or
The purpose of this study was to evaluate the hepatoprotective effect of maltol, a food-flavoring agent, on alcohol-induced acute oxidative damage in mice. Maltol used in this study was isolated from red ginseng (Panax ginseng C.A Meyer) and analyzed by high performance liquid chromatography (HPLC)
Cancer is one of the main causes of death worldwide. Chemotherapy, despite its severe sides effect, is to date one of the leading strategies against cancer. Metal-based drugs present several potential advantages when compared to organic ones and gained trust from the scientific community after the
The reaction of the dimer [Rh(III)(pentamethylcyclopentadienyl)(μ-Cl)Cl]2 ([Rh(III)(Cp*)(μ-Cl)Cl]2) with the hydroxypyrone ligands maltol and allomaltol affords complexes of the general formula [Rh(III)(Cp*)(L)Cl] under standard and microwave conditions. The organometallic compounds were
BACKGROUND
Hydroxypyrones represent several classes of molecules known for their high synthetic versatility. This family of molecules shows several interesting pharmaceutical activities and is considered as a promising source of new antineoplastic compounds.
METHODS
In the quest to identify new
Maltol, a food-flavoring agent and Maillard reaction product formed during the processing of red ginseng (Panax ginseng, C.A. Meyer), has been confirmed to exert a hepatoprotective effect in alcohol-induced oxidative damage in mice. However, its beneficial effects on acetaminophen
The purpose of this research was to evaluate whether maltol could protect from hepatic injury induced by carbon tetrachloride (CCl₄) in vivo by inhibition of apoptosis and inflammatory responses. In this work, maltol was administered at a level of 100 mg/kg for 15 days prior to exposure to a single
This study aimed to investigate the anti-oxidative properties of the ethanolic extracts of the devil's club (Oplopanax horridus) leaves, stems, and roots. Furthermore, the anti-inflammatory activity of the leaf extract was analyzed. The leaf extract had higher total phenolic and flavonoid contents
The stoichiometry and stability constants of the Ga(III) complexes of 8-hydroxyquinoline (HQ), 8-hydroxyquinoline-5-sulfonate (HQS), maltol, thiomaltol, allomaltol and thioallomaltol were determined by means of pH-potentiometry, UV-vis spectrophotometry, spectrofluorometry and (1)H NMR spectroscopy
BACKGROUND
Identification of new drugs against paediatric sarcomas represents an urgent clinical need that mainly relies on public investments due to the rarity of these diseases. In this paper we evaluated the in vitro and in vivo efficacy of a new maltol derived molecule (maltonis), belonging to
Pyran-4-one (maltol, kojic acid and chlorokojic acid 1) esters of adamantan-1-ylacetic acid were prepared through efficient synthetic routes in good yields and evaluated for their in vitro antiproliferative activity on four cancer cell lines: K562 (chronic myelogenous leukemia), HeLa (cervical
Worldwide, green tea is one of the most popular beverages. It promotes blood circulation, liver function, and lowers the risk of cancer and cardiovascular diseases. This drink is characterized by the distinctive odors and flavors produced by its constituent compounds, with its value predicated on
Recent studies suggest that electronic cigarette (e-cig) flavors can be harmful to lung tissue by imposing oxidative stress and inflammatory responses. The potential inflammatory response by lung epithelial cells and fibroblasts exposed to e-cig flavoring chemicals in addition to other
