Thrombin is a crucial enzyme in the coagulation cascade, and inhibitors of thrombin have been extensively studied as potential antithrombotic agents. The objective of this study was to identify natural inhibitors of thrombin from Panax notoginseng and evaluate their biological activity in vitro and binding characteristics. A combined approach involving molecular docking, thrombin inhibition assays, surface plasmon resonance, and molecular dynamics simulation was utilized to identify natural thrombin inhibitors. The results demonstrated that panaxatriol directly inhibits thrombin, with an IC50 of 10.3 µM. Binding studies using surface plasmon resonance revealed that panaxatriol interacts with thrombin, with a KD value of 7.8 µM. Molecular dynamics analysis indicated that the thrombin-panaxatriol system reached equilibrium rapidly with minimal fluctuations, and the calculated binding free energy was − 23.8 kcal/mol. The interaction between panaxatriol and thrombin involves the amino acid residues Glu146, Glu192, Gly216, Gly219, Tyr60A, and Trp60D. This interaction provides a mechanistic basis for further optimizing panaxatriol as a thrombin inhibitor. Our study has shown that panaxatriol serves as a direct thrombin inhibitor, laying the groundwork for further research and development of novel thrombin inhibitors. [ABSTRACT FROM AUTHOR]

• The photocatalytic properties and mechanism of medium entropy alloys coupled Z-scheme heterojunction are reported for the first time. • The mechanism of alloying enhancing LSPR effect has been thoroughly investigated. • Three working ways of enhancing photocatalytic performance by LSPR effect has been studied. • The as-prepared material realizes the multi-gradient transfer of photogenerated carriers. Optimizing the local surface plasmon resonance (LSPR) effect of non-noble metals through alloying has been crucial for improving its practical application in the field of photocatalysis. Rare studies capture the detail that the change in the electronic structure of metal elements caused by alloying affects plasma carrier concentration and the local surface plasmon resonance effect. Herein, NiCuCoFe medium-entropy alloys (MEAs) nanoclusters were designed and used to modify the Bi 3 O 4 Br/CNNs Z-scheme heterojunction. The cocktail effect of MEAs causes the 3d-orbital hybridization of various metal elements, which promotes the release of charge carriers. The higher the carrier concentration, the stronger the LSPR effect of MEAs. In addition, the mechanism of three typical working pathways of the LSPR effect to improve the photocatalytic performance of heterojunction is discussed. And compared with those of Bi 3 O 4 Br, CNNs, and Bi 3 O 4 Br/CNNs, the rate constant of MEAs-Bi 3 O 4 Br/CNNs was 3.26, 11.16, and 3.17 times higher during the degradation of norfloxacin, respectively. This study provides a new strategy for understanding the mechanism of LSPR and the rational design of plasmonic coupling architectures for enhanced photocatalysis.

• Novel sulfur-vacancy-rich Bi/Bi 2 S 3 /SnS 2 heterojunction was constructed in situ. • Bi/Bi 2 S 3 /SnS 2 exhibits excellent activity for Cr(VI) reduction and N 2 fixation. • The synergistic effect of SVs and heterostructure can enhance the performance. • The abundant SVs can efficiently facilitate the adsorption and activation of N 2. • The SPR effect of metal Bi can effectively expand the optical absorption range. Highly competent and economical photocatalysts are one of the most charming targets in environmental restoration and clean production. Herein, a novel sulfur-vacancy-rich Bi/Bi 2 S 3 /SnS 2 Z-scheme heterostructure was constructed in situ and applied for the photoreduction Cr(VI) and nitrogen fixation. The fabricated Bi/Bi 2 S 3 /SnS 2 –2 exhibits the optimum photoreduction Cr(VI) performance with the efficiency of 94.5% within 15 min visible light irradiation. The remarkably enhanced catalytic efficiency derived from the synergistic effect of the construction of intimate contacted interface, abundant sulfur vacancy and surface plasmon resonance (SPR) effect of metal Bi. Meanwhile, the excellent photocatalytic nitrogen fixation property (96.4 μmol g–1 h–1) was achieved by Bi/Bi 2 S 3 /SnS 2 –2 under full solar illumination because sulfur vacancy could provide sufficient catalytic sites to accelerate the adsorption and nitrogen activation. The Z-scheme heterostructure was proposed to expound the photocatalytic mechanism. This work offers a new perspective on hierarchical heterostructure with plentiful vacancies for environmental remediation and energy development. [Display omitted] [ABSTRACT FROM AUTHOR]
