Abstract
Trisulfide unit is widely found in natural products and has garnered attention due to the unique pharmacological and physiochemical properties. However, despite limited progress, widely applicable approaches for constructing unsymmetrical trisulfides have so far remain scarce. In this work, an easy-to-prepare, solid-state and scalable reagent, S-substituted sulphenylthiosulphate, has been developed for the divergent synthesis of unsymmetrical trisulfides. Alkyl electrophile substrates, including bromides, chlorides, iodides and tosylates, with diverse substituents are smoothly converted to the corresponding trisulfides with S-substituted sulphenylthiosulphates and thiourea as another sulfur source. Furthermore, the late-stage modification of drug molecules was successfully achieved through this method.

Abstract
The dysregulation of c-Met kinase has emerged as a significant contributing factor for the occurrence, progression, poor clinical outcomes and drug resistance of various human cancers. In our ongoing pursuit to identify promising c-Met inhibitors as potential antitumor agents, a docking study of the previously reported c-Met inhibitor 7 revealed a large unoccupied hydrophobic pocket, which could present an opportunity for further exploration of structure-activity relationships to improve the binding affinity with the allosteric hydrophobic back pocket of c-Met. Herein we performed structure-activity relationship and molecular modeling studies based on lead compound 7. The collective endeavors culminated in the discovery of compound 21j with superior efficacy to 7 and positive control foretinib by increasing the hydrophobic interaction with the hydrophobic back pocket of c-Met active site.

Abstract
Two-dimensional (2D) MoSi2N4is a newly created material that has superstability and ultrahigh carrier mobility. Besides, the hydrogen evolution reaction activity was proved excellent by doping transition metal (TM) atoms and introducing N vacancies. But, the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) of 2D MoSi2N4is unclear even. We have explored the electrocatalytic properties (OER/ORR) of MoSi2N4by introducing Si vacancies and attaching various TM atoms. The structure and optoelectronic characteristics of MoSi2N4have been researched in detail using density functional theory calculations. By analyzing the density of states, the free energy change diagram and contour maps of TM@VSi-MoSiN, the results show that Co@VSi-MoSiN has the lowest OER overpotential (0.53 V) among all samples. Additionally, the d-band center is used to explain the electrocatalytic origin of the OER and ORR of TM@VSi-MoSiN. Our discoveries expand the 2D TM@VSi-MoSiN applicability in the realm of catalysis.
