The stability and bioavailability of lentztrehaloses A, B, and C as re (...)
Trehalose is widely used as a sweetener, humectant, and stabilizer, but is ubiquitously degraded by the enzyme trehalase expressed in a broad variety of organisms. The stability of the new trehalose analogues lentztrehaloses A, B, and C in microbial and mammalian cell cultures and their pharmacokinetics in mice were analyzed to evaluate their potential as successors of trehalose. Among the 12 species of microbes and 2 cancer cell lines tested, 7 digested trehalose, whereas no definitive digestion of the lentztrehaloses was observed in any of them. When orally administered to mice (0.5 g/kg), trehalose was not clearly detected in blood and urine and only slightly detected in feces. However, lentztrehaloses were detected in blood at >1 μg/mL over several hours and were eventually excreted in feces and urine. These results indicate that lentztrehaloses may potentially replace trehalose as nonperishable materials and drug candidates with better bioavailabilities.

The Radioprotective Effects of Curcumin and Trehalose Against Genetic (...)
Background: Thyroid cancer has been growing rapidly during the last decades. Radioiodine-131 (I-131) as an appropriate therapy modality is currently using in the treatment of cancer and hyperthyroidism diseases. This radiotracer is considered as a cause of oxidative DNA damage in nontarget cells and tissues. The aim of this study was to investigate the effects of curcumin and trehalose on the level of DNA double-strand breaks (DSBs) caused by I-131 in human lymphocytes. Materials and Methods: First, 6-mL blood samples were taken from each of the five volunteers. After 1 h of preincubation with the antioxidants, a total of 20 μCi I-131/2 mL (blood + NaCl) was added to each sample, and then, the samples were reincubated for 1 h. Lymphocytes were separated and the mean DSB levels were measured for each sample through γ-H2AX assay to evaluate the effects of antioxidants. Results: After 1-h incubation with I-131, the DSBs increased by 102.9% compared to the control group (0.343 vs. 0.169 DSB/cell; P = 0.00). Furthermore, compared to the control + I-131 group, curcumin and trehalose reduced the DSBs by 42% and 38%, respectively. There was a significant decrement (P = 0.00) in the levels of DSBs of the curcumin + I-131 and trehalose + I-131 subgroups compared to the control + I-131 subgroup. Furthermore, there was no significant relationship between the radioprotective effect of curcumin and trehalose (P = 0.95). Conclusion: The use of curcumin and trehalose as antioxidant can reduce the numbers of DSBs caused by I-131. Meanwhile, the radioprotective effect of curcumin was more than trehalose.

Compositional Characteristics and In Vitro Evaluations of Antioxidant (...)
Fucoidan, a fucose-containing sulfated polysaccharide with diverse biological functions, is mainly recovered from brown algae. In this study, we utilized a compressional-puffing process (CPP) to pretreat Sargassum crassifolium (SC) and extracted fucoidans from SC by warm water. Three fucoidan extracts (SC1: puffing at 0 kg/cm2; SC2: puffing at 1.7 kg/cm2; and SC3: puffing at 6.3 kg/cm2) were obtained, and their composition, and antioxidant and neuroprotective activities were examined. The results suggest that CPP decreased the bulk density of algal samples, expanded the algal cellular structures, and eliminated the unpleasant algal odor. The extraction yields of fucoidans were increased and impurities of fucoidans were decreased by increasing the pressures used in CPP. The SC1–SC3 extracts displayed various characteristics of fucoidan as illustrated by the analyses of composition, Fourier transform infrared (FTIR) spectroscopy, and molecular weight. All three extracts SC1–SC3 showed antioxidant activity dose-dependently. Although both SC1 and SC2 possessed high and similar neuronal protective properties, SC2 showed a higher extraction yield, higher efficacy in the reversion of H2O2-induced cytotoxicity in rat pheochromocytoma PC-12 cells, and lower impurities compared with SC1, and thus SC2 is suggested as a good candidate for a therapeutic agent in the preventive treatment of neurodegenerative diseases.
Site-Specific Insulin-Trehalose Glycopolymer Conjugate by Grafting fro (...)
Insulin is an important therapeutic protein for the treatment of diabetes, but it is unstable and aggregates upon exposure to environmental stressors encountered during storage and transport. To prevent degradation of the protein in this manner and retain as much in vivo bioactivity as possible, a well-defined insulin–trehalose glycopolymer conjugate was synthesized. To accomplish this, a strategy was employed to site-specifically modify insulin with a polymerization initiator at a particular conjugation site; this also facilitated purification and characterization. Lysine of the B chain was preferentially modified by conducting the reaction at high pH, taking advantage of its higher nucleophilicity than the N-terminal amines. Trehalose monomer was polymerized directly from this macroinitiator to form a well-defined conjugate. Bioactivity of the site-specific conjugate was shown to be higher compared to the nonspecific conjugate and the same as the analogous site-specific poly(ethylene glycol) (PEG) conjugate, as confirmed by the insulin tolerance test (ITT) in mice. The conjugated trehalose glycopolymer also stabilized insulin to heat as measured by high-performance liquid chromatography (HPLC).

Trehalose and Magnesium Chloride Exert a Common Anti-amyloidogenic Eff (...)
Many degenerative disorder such as Parkinsons, Alzheimers, Huntingtons disease, etc are caused due to the deposition of amyloid fibrils, formed due to the ordered aggregation of misfolded/unfolded proteins. Misfolded or unfolded proteins aggregate mostly through hydrophobic interactions which are unexposed in native state, but become exposed upon unfolding. To counteract amyloid related diseases, inhibition of the protein self assembly into fibril is a potential therapeutic strategy. The study aims at investigating the effect of selected compounds, namely trehalose and magnesium chloride hexahydrate towards inhibition and disaggregation of amyloid fibrils using Hen Egg White Lysozyme as a model. We further attempted to understand the mechanism of action with the help of various biophysical, microscopic as well as computational studies. A common mechanism of action was identified where the selected compounds exert their anti-amyloidogenic effects by altering HEWL conformations characterized by reduction in the beta sheet content and decrease in exposed hydrophobic surfaces. The altered conformation seems to have lesser amyloidogenic propensity leading to inhibition as well as disaggregation of amyloids.

Role of trehalose on antioxidant defense system and some osmolytes of quinoa plants under water deficit SpringerLink
Background For scavenging reactive oxygen species, plant possess effective system that protect them from destructive oxidative reaction. Parts of this system as osmoprotectants and antioxidative enzymes are key elements in the defense mechanisms. A field experiment was conducted to evaluate the potential of foliar treatment of trehalose (Tre) with different concentrations (0, 0.1 mM, or 0.5 mM) in improving antioxidant defense system of quinoa plant under normal irrigation and drought stress conditions. Results Drought stress caused significant increases in some osmoprotectants as glucose, trehalose, TSS, free amino acids, and proline. Meanwhile, trehalose foliar treatment with different concentrations significantly decreases in free amino acids and proline contents. More accumulation of the tested organic solutes of leaves (glucose, sucrose, trehalose, TSS) of the trehalose-treated plant in both normal irrigated and drought-stressed quinoa plants as compared with the corresponding controls. Treating quinoa plants with trehalose resulted in significant decrease in lipid peroxidation, hydrogen peroxide contents, and LOX activity in normal irrigated and drought-stressed plants. These decreases correlated with significant increases in total phenolic contents as compared with untreated control. Different concentrations of trehalose resulted in significant increases in antioxidant enzymes. Maximum increase antioxidant enzymes were observed by treating plants Tre at 0.5 mM either under normal irrigation or drought conditions. Conclusion It could be concluded that foliar spray of trehalose was effective in improving quinoa performance by reducing hydrogen peroxide free radical and by enhancing antioxidant compounds (phenolics), compatible osmolytes, membrane stability, and antioxidant enzymes.
