AB  - In vitroacetylholinesterase (AChE) inhibitory activity of an autochthonous sample of the mushroomCoprinus comatus(encompassing fruiting body FB, mycelia M and filtrate F from the submerged cultivation) was the subject of this study.C. comatusF extract exhibited rather potent anti-AChE activity (73.0 +/- 1.5%) atin liquidconditions, comparable to those of the conventional drug donepezil (80.6 +/- 1.4%). Also, the same extract exhibited high anti-AChE activity (1 mu g)in solid. While its FTIR spectrum indicated the presence of phenolic compounds, quercetin (28.1 mu g g(-1)d.w.) was found to affect the observed bioactivity (59.8 +/- 0.9%). This is the first report of profound anti-AChE activity of anyC. comatusextract, a medicinal mushroom that has been successfully cultivated in P.R. China, due to the demanding needs of food industry.

AB  - The polysaccharide (PSH) extracts from the edible mushroom species Coprinus comatus and Coprinellus truncorum were screened in liquid for their acetylcholinesterase inhibitory (AChE) activity. Both extracts were found to display inhibition of the aforementioned enzyme reaching similar IC50 values of 0.62 +/- 0.07 and 0.61 +/- 0.03 mg/mL, respectively. According to the means of FTIR spectroscopy, these PSH extracts mostly contained beta-glucans. However, the presence of some proteins and polyphenolics as minor ingredients were also detected. Compared with existing literature data for anti-AChE activity of the sugar samples, the findings within this study may be treated as a profound bioactivity. Consequently, this study puts some light on the possible use of the screened macrofungi in the palliative treatment of Alzheimer's disease. [GRAPHICS] .

AB  - This study outlines antioxidant and anti-AChE activities of the polysaccharide (PSH) extract from the mushroom species Amanita strobiliformis. Both the presence of alpha and ss glucans within the aforementioned extract was recorded. PSH extract displayed a profound scavenging activity of OH radicals (IC50 value, 11.86 +/- 0.59 mu g/mL) and high potential for reduction of Fe3+ ions (174.11 +/- 8.70 mg eq. AA/g d.w.) being almost 48- and 5-fold more effective than mannitol and butylated hydroxytoluene used as a positive control, respectively. Compared with galanthamine (0.001 mu g), the same extract exhibited a moderate anti-AChE activity (10 mu g) in solid. Since purified PSH extract exhibited higher bioactivity (IC50 value 7.27 +/- 0.31 mu g/mL, 197.68 +/- 9.47 mg eq. AA/g d.w. and 0.1 mu g, respectively), it can be predominantly ascribed to the polysaccharide compounds. A. strobiliformis PSH extract may be considered as a promising resource of potent bioactive polysaccharides of natural origin successfully addressing both oxidative stress and lack of acetylcholine.

AB  - Cerium oxide (CeO2) nanoparticles (CONPs) are interesting biomaterials with various applications in biomedicine, cosmetics and the pharmaceutical industry, but with limited practical application because of their low stability in aqueous media. The aim of this study was to obtain CONPs with increased stability by coating the particles. Microbial exopolysaccharides (levan, pullulan) and glucose were used to prepare CONPs under different synthesis conditions. Coating was attempted by adding the carbohydrates during (direct coating) or after (subsequent coating) the synthesis of CONPs. The obtained nanoparticles were characterized by X-Ray diffraction analysis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The suspension stability of the uncoated and coated CONPs in aqueous media was evaluated by measuring the hydrodynamic size, zeta potential and turbidity. The FT-IR spectra revealed the differences between coated CONPs and showed the success of subsequent coating with carbohydrates. Coating with carbohydrates improved the stability the CONP suspension by decreasing the size of aggregated particles. The suspensions of levan- and glucose-coated CONPs had the best stability. In this study, CONPs were prepared using non-toxic materials, which were completely environmentally friendly. The obtained results open new horizons for CONP synthesis, improving their biological applications.

AB  - This study aimed to determine antiradical (DPPH center dot and (OH)-O-center dot) and acetylcholinesterase (AChE) inhibitory activities along with chemical composition of autochtonous fungal species Trametes versicolor (Serbia). A total of 38 phenolic compounds with notable presence of phenolic acids were identified using HPLC/MS-MS. Its water extract exhibited the highest antiradical activity against (OH)-O-center dot (3.21 mu g/mL), among the rest due to the presence of gallic, p-coumaric and caffeic acids. At the concentration of 100 mu g/mL, the same extract displayed a profound AChE inhibitory activity (60.53%) in liquid, compared to donepezil (89.05%), a drug in clinical practice used as positive control. The flavonoids baicalein and quercetin may be responsible compounds for the AChE inhibitory activity observed. These findings have demonstrated considerable potential of T. versicolor water extract as a natural source of antioxidant(s) and/or AChE inhibitor(s) to be eventually used as drug-like compounds or food supplements in the treatment of Alzheimer's disease.
