IFN-gamma exhibits differential effects depending on the target and can induce cellular activation and enhance survival or mediate cell death via activation of apoptotic pathways. In this study, we demonstrate an alternative mechanism by which IFN-gamma enhances tumor recognition, mediated by the active release of Hsp72. We demonstrate that stimulation of 4T1 breast adenocarcinoma cells and K56...

Abstract Hydroxycitronellal has been widely used in foods, beverages, perfumery and cosmetics. It can also be to treat anxiety. The major drawbacks regarding the use of hydroxycitronellal are related water insolubility, volatility, instability, sensitization. To overcome these concerns, β-cyclodextrin was adopted as wall material encapsulate this work. Hydroxycitronellal-β-cyclodextrin inclusio...

Lisuride is an ergot alkaloid derivative with dopaminergic activity. It is used for treatment of Parkinsonism and some other diseases associated with high level of prolactine. Lisuride is a chiral compound derived from natural ergot alkaloids. A new capillary zone electrophoresis (CZE) method capable of separating the enantiomers of lisuride was developed. Using the optimized conditions (acidic...

Fisetin is a natural antioxidant with a wide range of nutraceutical properties, including antidiabetic, neuroprotecting, and suppression or prevention of tumors. The present work describes the preparation of a water-soluble, solid inclusion compound of fisetin with gamma-cyclodextrin (γ-CD), a cyclic oligosaccharide approved for human consumption. A detailed physicochemical analysis of the prod...

We investigated the simultaneous chiral separation of nine amphetamine type stimulants (dl-norephedrine, dl-norpseudoephedrine, dl-ephedrine, dl-pseudoephedrine, dl-amphetamine, dl-methamphetamine, dl-methylenedioxyamphetamine (MDA), dl-methylenedioxymethamphetamine (MDMA), and dl-methylenedioxyethylamphetamine (MDEA)) by capillary electrophoresis using highly sulfated gamma-cyclodextrin (SU(XI...

Cyclodextrins are naturally oligosaccharides which had cyclic glucopyranoside units even if six to form α-cyclodextrin (α-CD), seven β-cyclodextrin (β-CD) or eight γ-cyclodextrin (γ-CD) and some other derivatives. It has a truncated cone shape with hydrophobic cavity hydrophilic from the external surface of cyclodextrins. Gold nanoparticles incorporated cyclodextrins enhanced optical electrical...

The aim was to study the ability of bioadhesive cyclodextrin-poly(anhydride) nanoparticles as carriers for the oral delivery of atovaquone (ATO). In order to increase the loading capacity of ATO by poly(anhydride) nanoparticles, the following oligosaccharides were assayed: 2-hydroxypropyl-β-cyclodextrin (HPCD), 2,6-di-O-methyl-β-cyclodextrin (DCMD), randomly methylated-β-cyclodextrin (RMCD) and...
