Natto contains a potent fibrinolytic enzyme called nattokinase (NK), which has thrombolytic, antihypertensive, antiatherosclerotic and lipid-lowering effects. Although NK has been recognized for its beneficial effect on humans with atherosclerotic cardiovascular disease (ASCVD), the underlying mechanisms involved in vascular inflammation-atherosclerosis development remain largely unknown. The current study aimed to explore the effects of NK on gene regulation, autophagy, necroptosis and inflammasome in vascular inflammation. The transcriptional profiles of NK in endothelial cells (ECs) by RNA sequencing (RNA-seq) revealed that NK affected THBS1, SRF and SREBF1 mRNA expression. In Q-PCR analysis, SRF and THBS1 were upregulated but SREBF1 was unaffected in ECs treated with NK. NK treatment induced autophagy and inhibited NLRP3 inflammasome and necroptosis in ECs. Furthermore, the inhibition of SRF or THBS1 by siRNA suppressed autophagy and enhanced the NLRP3 inflammasome and necroptosis. In a mouse model, NK reduced vascular inflammation by activating autophagy and inhibiting NLRP3 inflammasome and necroptosis. Our findings provide the first evidence that NK upregulates SRF and THBS1 genes, subsequently increasing autophagy and decreasing necroptosis and NLRP3 inflammasome formation to reduce vascular inflammation. Therefore, NK could serve as nutraceuticals or adjuvant therapies to reduce vascular inflammation and possible atherosclerosis progression. © 2024 Elsevier B.V.

Recent advancements in the discovery of natural products have made significant progress in rapidly identifying known compounds from complex extracts using advanced spectroscopic technologies. Among these methods, one powerful approach called MS/MS molecular networking (MN) organizes chemical similarity based on MS/MS fragmentation data, serving as a valuable complement to traditional dereplication strategies. In our ongoing research focused on lead discovery from a sustainable medicinal source, an aquaculture soft coral Sarcophyton trocheliophorum, the MN profiling approach revealed the chemical diversity of biscembranoid analogs. By analyzing the MN pattern, biscembranoid derivatives with unique MS/MS fragments were prioritized for further investigation. Two novel biscembranoids, sarcotroxide A (1) and B (2), were successfully obtained through targeted isolation. These novel biscembranes contained an unprecedented 3-hydroperoxy-3-methylcyclohex-1-ene moiety compared with all biscembranoid analogs. The chemical structures of the two new biscembranoids were confirmed through spectroscopic analyses and in silico calculations. Their anti-inflammatory properties were assessed against the generation of superoxide anion (O₂^•−) and elastase release in activated human neutrophils. Sarcotroxides A (1) and B (2) exhibited anti-inflammatory activity by inhibiting O₂^•− accumulation (with 43.67% and 61.62% inhibition) and elastase release (with 38.21% and 61.62% inhibition) at 10 µM. These findings validated the potential of these biscembranoids from the cultured S. trocheliophorum as promising candidates for the future development of anti-inflammatory agents specifically designed to target neutrophils. © 2023 The Authors

The naturally occurring bile acid lithocholic acid (LCA) has been a crucial core structure for many non-sugar-containing sialyltranferase (ST) inhibitors documented in literature. With the aim of elucidating the impact of the terminal carboxyl acid substituent of LCA on its ST inhibition, in this present study, we report the (bio)isosteric replacement-based design and synthesis of sulfonate and sulfate analogues of LCA. Among these compounds, the sulfate analogue SPP-002 was found to selectively inhibit N-glycan sialylation by at least an order of magnitude, indicating a substantial improvement in both potency and selectivity when compared to the unmodified parent bile acid. Molecular docking analysis supported the stronger binding of the synthetic analogue in the enzyme active site. Treatment with SPP-002 also hampered the migration, adhesion, and invasion of MDA-MB-231 cells in vitro by suppressing the expression of signaling proteins involved in the cancer metastasis-associated integrin/FAK/paxillin pathway. In totality, these findings offer not only a novel structural scaffold but also valuable insights for the future development of more potent and selective ST inhibitors with potential therapeutic effects against tumor cancer metastasis.

BACKGROUND:The main commercially available methods for detecting small molecules of mycotoxins in traditional Chinese medicine (TCM) and functional foods are enzyme-linked immunosorbent assay and mass spectrometry. Regarding the development of diagnostic antibody reagents, effective methods for the rapid preparation of specific monoclonal antibodies are inadequate. METHODS:In this study, a novel synthetic phage-displayed nanobody Golden Glove (SynaGG) library with a glove-like cavity configuration was established using phage display technology in synthetic biology. We applied this unique SynaGG library on the small molecule aflatoxin B1 (AFB1), which has strong hepatotoxicity, to isolate specific nanobodies with high affinity for AFB1. RESULT:These nanobodies exhibit no cross-reactivity with the hapten methotrexate, which is recognized by the original antibody template. By binding to AFB1, two nanobodies can neutralize AFB1-induced hepatocyte growth inhibition. Using molecular docking, we found that the unique non-hypervariable complementarity-determining region 4 (CDR4) loop region of the nanobody was involved in the interaction with AFB1. Specifically, the CDR4's positively charged amino acid arginine directed the binding interaction between the nanobody and AFB1. We then rationally optimized the interaction between AFB1 and the nanobody by mutating serine at position 2 into valine. The binding affinity of the nanobody to AFB1 was effectively improved, and this result supported the use of molecular structure simulation for antibody optimization. CONCLUSION:In summary, this study revealed that the novel SynaGG library, which was constructed through computer-aided design, can be used to isolate nanobodies that specifically bind to small molecules. The results of this study could facilitate the development of nanobody materials to detect small molecules for the rapid screening of TCM materials and foods in the future.

In order to enhance enzyme activities of koji and further improve the health benefits and nutritional value of miso, puffed rice was used to prepare koji with optimization of fermentation utilizing response surface methodology (RSM), and the optimized puffed rice koji was used to produce miso and low-salt miso. Results showed that β-glucosidase activity increased by 1.98-fold after RSM optimization. The optimized puffed rice koji also showed the highest β-amylase and protease activities (237.1 and 968.8 units/g, respectively) compared to rice koji (108.7 and 637.4 units/g, respectively). Moreover, miso made from puffed-rice koji presented a much higher polyphenol content, antioxidant activity, and aglycone conversion. These findings clarified the relationship between changes in enzyme activities in koji and the important components of miso, and also advance solid-state fermentation research and development of functional miso. © 2024

Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of mortality and morbidity worldwide. Chronic inflammation of the endothelium is a pivotal process in the pathogenesis of ASCVD. Therefore, the identification of pro-atherogenic gene expression and subsequent screening out of potential therapeutic agents for vascular inflammation is an attractive issue. The TICAM1 and IRF3 genes were identified as susceptibility genes whose expression was upregulated in lipopolysaccharide (LPS)-induced vascular inflammation. Cilostazol was found to be the most potential bioactive drug for the TICAM1 proteins. Cilostazol pretreatment also increased autophagy and decreased necroptosis and NLRP3/NLRP6 inflammasome formation, as well as the pro-inflammatory cytokine interleukin-1β, in vitro and in vivo . Additionally, cilostazol significantly attenuated the TNF–α–induced elevation in circulating adhesion molecules. Furthermore, cilostazol treatment markedly reduced aortic wall thickening in TNF–α–challenged mice. After experiments into mechanistic understanding, we found that the candidate drug cilostazol reduces vascular inflammation and possibly atherosclerosis progression. Therefore, this study can offer broader evidence of cilostazol for treating individuals with ASCVD or at high risk of ASCVD. Further prospective clinical trials are warranted to confirm its application and effectiveness.

Repeated-batch fermentation with fungal mycelia immobilized in plastic composite support (PCS) eliminates the lag phase during fermentation and improves metabolite productivity. The strategy is implemented herein, and a novel modified PCS is developed to enhance exopolysaccharide (EPS) production from the medicinal fungus Cordyceps militaris. A modified PCS (SYE + PCS) was made by compositing polypropylene (PP) with a nutrient mixture containing soybean hull, peptone, yeast extract, and minerals (SYE+). The use of SYE + PCS has consistent cell productivity throughout the multiple fermentation cycles, which resulted in a more higher cell productivity after second batch compared to unmodified PCS. The cell grown on SYE + PCS also generates a higher yield of EPS (3.36, 6.93, and 5.72 g/L in the first, second, and third fermentation cycles, respectively) up to three-fold higher than the cell immobilized on unmodified PCS. It is also worth noting that the EPS from mycelium grown on SYE + PCS contains up to 2.3-fold higher cordycepin than those on unmodified PCS. The presence of nutrients in SYE + PCS also affects the hydrophobicity and surface roughness of the PC, improving mycelial cell adhesion. This study also provides a preliminary antioxidant activity assessment of EPS from immobilized C. militaris grown with SYE + PCS. © 2023

In recent years, bacterial cellulose (BC), a crystalline and nanoscale fibrillar polymer, has garnered significant interest due to its superior physical, chemical, and mechanical properties compared to plant cellulose. Inherent features of BC, which include high biodegradability, mechanical strength, and biocompatibility, make it a suitable material for use in a wide variety of applications, particularly in the domains of biomedicine and environmental science. However, realizing its full potential requires targeted chemical or physical modifications. Recent developments have focused on in-situ and ex-situ BC modification for various applications. Incorporating functional compounds into cellulose during BC synthesis enhances its strength and functional properties. Additionally, the material properties of BC, such as water content, thermal stability, and antibacterial capabilities, can be enhanced through post-synthesis modifications, including chemical acetylation, phosphorylation, and integration with other biopolymers. Currently, the applicability of BC is being improved using new modification techniques, which involve genetically engineered strains to enhance polymer characteristics and market potential. The review highlights recent advancements in BC research and novel modification strategies that enhance its applications in advanced biomedical engineering and sustainable packaging. © 2025
