Fischer, Christian;Veprek, Nynke A.;Peitsinis, Zisis;Ruhmann, Klaus-Peter;Yang, Chao;Spradlin, Jessica N.;Dovala, Dustin;Nomura, Daniel K.;Zhang, Yingkai;Trauner, Dirk research published 《 De novo Design of SARS-CoV-2 Main Protease Inhibitors》, the research content is summarized as follows. The COVID-19 pandemic prompted many scientists to investigate remedies against SARS-CoV-2 and related viruses that are likely to appear in the future. As the main protease of the virus, M ^Pro, is highly conserved among coronaviruses, it has emerged as a prime target for developing inhibitors. Using a combination of virtual screening and mol. modeling, we identified small mols. that were easily accessible and could be quickly diversified. Biochem. assays confirmed a class of pyridones as low micromolar noncovalent inhibitors of the viral main protease.

The human tyrosinase is the most prominent therapeutic target for pigmentary skin disorders. However, the overwhelming majority efforts have been devoted to search mushroom tyrosinase inhibitors, which show poor inhibitory activity on human tyrosinase and certain side effects that cause skin damage in practical application. Herein, a series of degraders that directly targeted human tyrosinase was firstly designed and synthesized based on newly developed PROTAC technol. The best PROTAC I induced human tyrosinase degradation obviously in dose and time-dependent manner, and its mechanism of inducing tyrosinase degradation has also been clearly demonstrated. Besides, encouraging results that low-toxicity PROTAC I was applied to reduce zebrafish melanin synthesis have been obtained, highlighting the potential to treatment of tyrosinase-related disorders. Moreover, this work has innovatively expanded the application scope of PROTAC technol. and laid a solid foundation for further development of novel drugs treating pigmentary skin disorders.

Fu, Jiaxu;Yan, Liuqing;Wang, Shuang;Song, Hongying;Gu, Qiang;Zhang, Yumin research published 《 Microwave-assisted synthesis and luminescent properties of triphenylamine substituted mono- and di- branched benzimidazole derivatives》, the research content is summarized as follows. In the present work, the synthesis of (benzoimidazolyl)-N,N-diphenylanilines I [R = H, Cl, Br, Me, CO₂H] and II using sodium metasulfite (Na₂S₂O₅) and p-toluenesulfonic acid (PTSA) sep. as catalysts was studied. Herein, the liquid phase microwave method was chosen to synthesize triphenylamine substituted mono- and di-branched benzimidazole derivatives compared with the solid phase microwave method, and the reaction conditions were optimized using Na₂S₂O₅ as a catalyst in N,N-dimethylformamide (DMF) solvent. A possible reaction mechanism was discussed. On this basis, PTSA using a catalyst was introduced into the reaction, the yields of the target products were evidently increased (the yield was enhanced 5-22% using PTSA as a catalyst). It is found that PTSA only acted as a catalyst, while Na₂S₂O₅ acted as both a catalyst and an oxidant, and PTSA could effectively catalyze the synthesis of benzimidazoles. Further, the luminescent properties of the synthesized compounds were comparatively studied after the structures of the synthesized compounds were confirmed. The results showed that the fluorescence quantum yield and the intensity of the synthesized compounds were enhanced with the increase in the number of substituted benzimidazole on triphenylamine, and the different substituents on 5-position of benzimidazole also had significant effect on the luminescent properties of the compound

Fung, Alfred. K. K.;Yu, Li-Juan;Sherburn, Michael S.;Coote, Michelle L. research published 《 Atom Transfer Radical Polymerization-Inspired Room Temperature (sp³)C-N Coupling》, the research content is summarized as follows. A simple nonphotochem. procedure is reported for Cu(I)-catalyzed C-N coupling of aliphatic halides with amines and amides. The process is loosely based on the Goldberg reaction but takes place readily at room temperature It uses Cu(I)Br, a commonly used and inexpensive atom transfer radical polymerization precatalyst, along with the cheap ligand N,N,N’,N”,N”-pentamethyldiethylenetriamine, to activate the R-X bond of the substrate via inner-sphere electron transfer. The procedure brings about productive C-N bond formation between a range of alkyl halide substrates with heterocyclic aromatic amines and amides. The mechanism of the coupling step, which was elucidated through application of computational methods, proceeds via a unique Cu(I) → Cu(II) → Cu(III) → Cu(I) catalytic cycle, involving (a) inner-sphere electron transfer from Cu(I) to the alkyl halide to generate the alkyl radical; (b) successive coordination of the N-nucleophile and the radical to Cu(II); and finally reductive elimination. In the absence of a nucleophile, debrominative homocoupling of the alkyl halide occurs. Control experiments rule out SN-type mechanisms for C-N bond formation.

A new polymeric membrane sensor for Cd(II) ion based on Me acrylate-acrylonitrile-Me methacrylate terpolymer as membrane carrier has been synthesized via atom transfer radical polymerization (ATRP) method at 60°C. Preliminary investigation with the membrane exhibited promising selectivity for Cd(II) ion with a slope of 32.02 mV/decade and the same could be estimated in the concentration range of 1 x 10-6 – 1 x 10-1 M in the working pH range of 4-6 for up to 90 days.
