“…Although high glass transition temperatures would keep the vaccine more stable during storage, replacing PVP by BSA enhanced vaccine virus stability (Table 1). Probably other stabilizing mechanisms such as hydrophobic interaction of BSA [22][23][24] with the enveloped ND vaccine were responsible for the vaccine storage stability, while PVP can only engage in hydrophilic interactions [25].…”

Dry powders containing a live-attenuated Newcastle disease vaccine (LZ58 strain) and intended for mass vaccination of poultry were prepared by spray drying using mannitol in combination with trehalose or inositol, polyvinylpyrrolidone (PVP) and/or bovine serum albumin (BSA) as stabilizers. These powders were evaluated for vaccine stabilizing capacity during production and storage (at 6ºC and 25ºC), moisture content, hygroscopicity and dry powder dispersibility. A mixture design, varying the ratio of mannitol, inositol and BSA, was used to select the stabilizer combination which resulted in the desired powder properties (i.e. good vaccine stability during production and storage, low moisture content and hygroscopicity and good dry-dispersibility). Inositol-containing powders had the same vaccine stabilizing capacity as trehalose powders, but were less hygroscopic. Incorporation of BSA enhanced the vaccine stability in the powders compared to PVP-containing formulations. However, increasing the BSA concentration increased the hygroscopicity and reduced the dry dispersibility of the powder. No valid mathematical model could be calculated for vaccine stability during production or storage, but the individual experiments indicated that a formulation combining mannitol, inositol and BSA in a ratio of 73.3:13.3:13.3 (wt/wt) resulted in the lowest vaccine titre loss during production (1.6-2.0 log 10 50% egg infectious dose (EID 50 ) and storage at 6ºC (max. 0.8 log 10 EID 50 after 6 months) in combination with a low moisture content (1.1-1.4%), low hygroscopicity (1.9-2.1% water uptake at 60% relative humidity) and good dry-dispersibility properties.

“…Thus, letting tumor cells to apoptosis is a requirement for an anticancer agent. It is generally accepted that cytotoxic drugs eliminate malignant cells by inducing apoptosis 32,33 . The activation of caspases, a family of important signaling molecules with various tasks depending on subtype and organ, is a marker for apoptosis 34 .…”

“…HSA has multiple binding sites for lower and higher fatty acids, and there are dedicated binding sites for aromatic compounds. Specific binding sites named Sudlow I and II are characterized by their binding of aromatic compounds . The amino acid sequence of HSA contains 17 disulfide bridges, one free thiol (Cys34) and a single tryptophan (Trp214), which may be vital when HSA binds with ligands along the chain …”

“…In the circulation, the binding process between a particular molecule and serum albumin may impact the structure of HSA. In other words, pathological factors can significantly alter the binding of ligands, and one such pathological condition is excess glucose . As the level of glucose increases, HSA is non‐enzymatically glycated to reduce sugar from blood.…”

Spectroscopic andin silicostudy of binding mechanism of cynidine‐3‐O‐glucoside with human serum albumin and glycated human serum albumin

The drug-serum albumin interaction plays a dominant role in drug efficacy and disposition. The glycation of serum albumin that occurs during diabetes may affect its drug-binding properties in vivo. In order to evaluate the interactivity characteristics of cyanidin-3-O-glucoside (C3G) with human serum albumin (HSA) and glycated human serum albumin (gHSA), this study was undertaken using multiple spectroscopic techniques and molecular modeling analysis. Time-resolved fluorescence and the thermodynamic parameters indicated that the quenching mechanism was static quenching, and hydrogen bonding and Van der Waals force were the main forces. The protein fluorescence could be quenched by C3G, whereas the polarity of the fluorophore was not obviously changed. C3G significantly altered the secondary structure of the proteins. Furthermore, the interaction force that existed in the HSA-C3G system was greater than that in the gHSA-C3G system. Fluorescence excitation emission matrix spectra, red edge excitation shift, Fourier transform infrared spectroscopy and circular dichroism spectra provided further evidence that glycation could inhibit the binding between C3G and proteins. In addition, molecular modeling analysis supported the experimental results. The results provided more details for the application of C3G in the treatment of diabetes.
