Cyclodextrins are natural macrocyclic oligosaccharides able to form inclusion complexes with a wide variety of guests, affecting their physicochemical and pharmaceutical properties. In order to obtain an improvement of the bioavailability and solubility of 5-fluorouracil, a pyrimidine analogue used as chemotherapeutic agent in the treatment of the colon, liver, and stomac cancers, the drug was ...

In the present investigation, eleven human adipose tissue samples, two seal blubber samples and two pelican muscles samples were analyzed with regard to their concentrations of PCB parent compounds as well as to the respective chiral methylsulfonyl metabolites 3-MeSO2-CB 91, 4-MeSO2-CB 91, 3-MeSO2-CB 95, 4-MeSO2-CB 95, 3-MeSO2-CB 149, 4-MeSO2-CB 149, 3-MeSO2-CB 132, 4-MeSO2-CB 132, 3-MeSO2-CB 1...

Abstract: Introduction: Embelin, a phytoconstituent obtained from Embelia ribes of the Myrsinaceae family, has anti-cancer, anti-inflammatory, anti-bacterial, anti-fertility, analgesic, antidiabetic, anti-depressant and wound healing activities. It is hydrophobic in nature leading to low bioavailability. Aim: The present study aims improve water solubility rate dissolution Embelin by complexati...

Defects in the gene encoding for the ATP binding cassette (ABC) transporter A1 (ABCA1) were shown to be one of the genetic causes for familial hypoalphalipoproteinemia (FHA). We investigated the role of ABCA1-mediated cholesterol efflux in Dutch subjects suffering from FHA. Eighty-eight subjects (mean HDL cholesterol levels 0.63 +/- 0.21 mmol/l) were enrolled. Fibroblasts were cultured and load...

Rofecoxib, a practically insoluble cox-2 selective nonsteroidal antiinflammatory agent was subjected to improvement in solubility by preparing its binary mixtures with beta cyclodextrin using various methods such as physical mixing, co-grinding, kneading with aqueous methanol and co-evaporation from methanol-water mixture. Characterization of the resulting binary mixtures by differential scanni...

Voriconazole is a first-line agent for treatment of systemic mycotic infections. However, intravenous use is contraindicated in patients with creatinine clearance <50 ml/minute because of accumulation of the toxic vehicle sulfobutyletherbeta-cyclodextrin sodium [1, 2]. In a recent issue of Critical Care, Kiser and colleagues furnished convincing pharmacological evidence that sulfobutylether-bet...

the purpose of this study was to produce oil in water nano-emulsion by ultrasonication, and investigate the influence of inulin and β-cyclodextrin on the prosperities of nano-emulsion and morphology of spray dried microcapsules. the results showed that emulsion droplet size in samples containing β-cyclodextrin (8.28±0.11 nm) was less than inulin samples (97.12±4.2 nm). considering sem photos, β...
