The relationship between the molecular structure of dietary flavonoids and their affinities for bovine serum albumin (BSA) were fully investigated by fluorescence titration analysis. The binding process with BSA was significantly affected by the molecular structure of flavonoids under study. The methylation of hydroxyl group in flavonoids enhanced their binding affinities for BSA by 1 to 794 ti...

dietary flavonoids show beneficial effects in the prevention of chronic diseases. however, flavonoid bioavailability is poor, probably due to their interaction with serum albumins. in the current work, the binding interactions of eight related flavonoids, sharing a similar core structure, with bovine serum albumin (bsa) were investigated by fluorescence spectroscopy. the binding affinities of t...

1-Methyl-3-(2-oxyethyl)-1H-Imidazol-3-ium-Borate Sulfonic Acid ([MOEI]-BSA) was easily prepared and used as a new and highly efficient solid acid catalyst for the synthesis of benzimidazole derivatives with high isolated yields. Various substituted benzimidazoles were synthesized by a combination of o-phenylenediamines and aldehydes in the presence of [MOEI]-BSA with excellent yields in water a...

The effects of lipid-rich bovine serum albumin (LR-BSA) on the development of porcine blastocysts produced in vitro were examined. Addition of 0.5 to 5 mg/ml LR-BSA to porcine blastocyst medium (PBM) from Day 5 (Day 0 = in vitro fertilization) significantly increased the hatching rates of blastocysts on Day 7 and the total cell numbers in Day-7 blastocysts. When Day-5 blastocysts were cultured ...

Effect of bovine serum albumin (BSA} on the absorption of sulfonamides was studied employing in situ recirculating perfusion method in the rat. The absorption rate constant of sulfamethoxazole was greatly decreased by addition of BSA to the perfusion solution. But, the decreasing effect of BSA on the absorption rate was diminished after removing BSA from perfusion solution. The decreasing effec...

Interaction between bovine serum albumin (BSA) and phosphorus heterocycles (PHs) was studied using multi-spectroscopic techniques. The results indicated the high binding affinity of PHs to BSA as it quenches the intrinsic fluorescence of BSA. The experimental data suggested the fluorescence quenching mechanism between PHs and BSA as a dynamic quenching. From the UV-vis studies, the apparent ass...

Three dietary monosaccharides, (glucose, fructose, and ribose), have different rates of protein glycation that accelerates the production of advanced glycation end-products (AGEs). The present work was conducted to investigate the effect of ferulic acid (FA) on the three monosaccharide-mediated protein glycations and oxidation of BSA. Comparing the percentage reduction, FA (1-5 mM) reduced the ...

Calcium-deficient hydroxyapatite (CDHA) nano-crystals incorporated with bovine serum albumin (BSA) to form BSA-loaded nano-carriers were synthesized via both in-situ and ex-situ processes. Amount of BSA uptake by the CDHA nano-crystals and subsequent release behaviors of the BSA-loaded nano-carriers were investigated. The amount of BSA uptake by CDHA decreases with increasing pH but a larger am...

BACKGROUND The importance of deciding the appropriate dose of anticancer agents cannot be overemphasized. Body surface area (BSA) has been used to calculate the dose in anticancer therapy since the 1950s. Japanese oncologists, often use their own Japanese BSA formula instead of western BSA formulae. However, it is not widely known that some discrepancies exist between the BSA products of the Ja...

INTRODUCTION The livertaxis of glycyrrhizic acid-conjugated bovine serum albumin (GL-BSA) has been reported in the literature. Now, in this paper, we describe a novel type of drug-targeted delivery system containing 10-hydroxycamptothecin (HCPT) with liver tumor targeting. METHODS First, GL was coupled to BSA then HCPT was encapsulated in GL-BSA by high-pressure homogenization emulsification....
