Abstract
Due to their high water content, frozen mushrooms (Agaricus bisporus) were greatly affected by ice crystal formation, which can lead to the destruction of tissue structure, serious browning, high juice loss, and difficulty in maintaining good sensory characteristics. In order to improve the quality of frozen Agaricus bisporus, this study employed Artificial neural network and genetic algorithm (ANN-GA) to optimize the amount of composite color protectant, and identified the optimal freezing conditions for freezing Agaricus bisporus by determining the freezing curves under different magnetic field-assisted freezing conditions, the color variance, texture and structure, drip loss, and distribution of moisture. Furthering, using X-ray μCT three dimensional images were taken to characterize the microstructure of the samples. Among them, the 6 mT magnetic field-assisted freezing treatment group was significantly better than the control group, and the results showed that the magnetic field-assisted freezing combined with chemical color protectant as a composite processing technology improved the quality of frozen Agaricus bisporus. This provides a theoretical basis and technical support for enhanced processing of frozen Agaricus bisporus.

RSC Adv 2024; 14:6085-6095. [PMID: 38370459 PMCID: PMC10870825 DOI: 10.1039/d4ra00007b] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Accepted: 02/05/2024] [Indexed: 02/20/2024] Open
Abstract
Tyrosinase is a widely distributed copper-containing enzyme found in various organisms, playing a crucial role in the process of melanin production. Inhibiting its activity can reduce skin pigmentation. Hydroquinone is an efficient inhibitor of tyrosinase, but its safety has been a subject of debate. In this research, a scaffold hybridization strategy was employed to synthesize a series of hydroquinone-benzoyl ester analogs (3a-3g). The synthesized compounds were evaluated for their inhibitory activity against mushroom tyrosinase (mTyr). The results revealed that these hydroquinone-benzoyl ester analogs exhibited inhibitory activity against mTyr, with compounds 3a-3e displaying higher activity, with compound 3b demonstrating the highest potency (IC50 = 0.18 ± 0.06 μM). Kinetic studies demonstrated that the inhibition of mTyr by compounds 3a-3e was reversible, although their inhibition mechanisms varied. Compounds 3a and 3c exhibited non-competitive inhibition, while 3b displayed mixed inhibition, and 3d and 3e showed competitive inhibition. UV spectroscopy analysis indicated that none of these compounds chelated with copper ions in the active center of the enzyme. Molecular docking simulations and molecular dynamics studies revealed that compounds 3a-3e could access the active pocket of mTyr and interact with amino acid residues in the active site. These interactions influenced the conformational flexibility of the receptor protein, subsequently affecting substrate-enzyme binding and reducing enzyme catalytic activity, in line with experimental findings. Furthermore, in vitro melanoma cytotoxicity assay of compound 3b demonstrated its higher toxicity to A375 cells, while displaying low toxicity to HaCaT cells, with a dose-dependent effect. These results provide a theoretical foundation and practical basis for the development of novel tyrosinase inhibitors.

Abstract
A potential strain, Paenibacillus sp. JNUCC32, was isolated and subjected to whole-genome sequencing. Genome functional annotation revealed its active metabolic capabilities. This study aimed to investigate the pivotal secondary metabolites in the biological system. Fermentation and extraction were performed, resulting in the isolation of seven known compounds: tryptophol (1), 3-(4-hydroxyphenyl)propionic acid (2), ferulic acid (3), maculosin (4), brevianamide F (5), indole-3-acetic acid (6), and butyric acid (7). Tryptophol exhibited favorable pharmacokinetic properties and demonstrated certain tyrosinase inhibitory activity (IC50 = 999 μM). For further analysis of its inhibition mechanism through molecular docking and molecular dynamics (MD) simulation, tryptophol formed three hydrogen bonds and a pro-Michaelis complex with tyrosinase (binding energy = -5.3 kcal/mol). The MD simulation indicated favorable stability for the tryptophol-mushroom tyrosinase complex, primarily governed by hydrogen bond interactions. The crucial residues VAL-283 and HIS-263 in the docking were also validated. This study suggests tryptophol as a potential candidate for antibrowning agents and dermatological research.

Biochem Biophys Res Commun 2023; 682:163-173.

Abstract
Ergothioneine, a natural derivative of histidine with a thiol/thine tautomeric structure, exhibits exceptional antioxidant properties and inhibition activities on tyrosinase. In this study, enzyme kinetics experiments and chromatographic spectral analysis revealed that ergothioneine inhibited tyrosinase in a reversible and non-competitive manner, with an inhibition constant of 0.554 mg/mL (2.41 mM). As the concentration of ergothioneine increased, the extremely flexible loop structure of tyrosinase extended from 40.1 % to 41.0 %, effectively covering the active center or binding site. Theoretical molecular docking simulation results show that ergothioneine forms complexes with tyrosinase through hydrogen bonding and salt bridges in the active center of Cu ions. Additionally, it was observed that ergothioneine's antioxidant had a stronger reducing impact on dopaquinone, an intermediate in melanin production, than the effect of ascorbic acid at an equivalent concentration (0.5 mg/mL). Ergothioneine reduced the intracellular reactive oxygen species to lower levels than the control group without UVA radiation and regulated the proliferation and differentiation in B16-F10 melanocytes. Clinical trials have shown that a 0.1 % concentration of ergothioneine can effectively suppress melanin production in irradiated skin. The significant reduction in melanin index and an increase in the individual type angle (ITA°) degree were measured after 4 weeks. These results collectively suggest that ergothioneine may be a promising inhibitor of natural antioxidant tyrosinase. Furthermore, due to its safety and efficacy, ergothioneine could be considered one of the bioactive substances for further study on diseases related to melanin production and tyrosinase activity which is of great significance for the cosmetics, medicine and food industries.

Abstract
Apart from demonstrating the interaction behavior of malondialdehyde (MDA) with Na+/K+-ATPase using in silico, the current study aims to investigate the effect of rheumatoid arthritis-related oxidative stress on Na+/K+-ATPase activity that is present in the erythrocyte cell membrane, which is rich in proteins vulnerable to damage from MDA and other free radicals. The target population of this study consists of 28 rheumatoid arthritis patients and 20 healthy volunteers whose MDA levels and Na+/K+-ATPase activity were determined. It was shown that MDA levels of rheumatoid arthritis patients increased (p < 0.001) and their Na+/K+-ATPase activity noticeably decreased when compared to those of healthy individuals. Also, according to this in silico modeling, MDA decreased Na+/K+-ATPase activity in line with the correlation analyses. Consequently, while elevated levels of MDA in the rheumatoid arthritis group were suggestive of oxidative stress, a decreased Na+/K+-ATPase-activity led us to speculate that the cellular membrane had sustained injury. Therefore, our results could be useful in explaining how MDA affects Na+/K+-ATPase activity in the interior of a specific molecular pathway.
