Chemical Research Letters, May 2021. Redox catalysis has been broadly utilized in electrochemical synthesis. The appropriate choice of redox mediator can avoid electrode passivation, which strongly inhibit the efficient activation of substrates. 7143-01-3, Name is Methanesulfonic anhydride, molecular formula is C2H6O5S2.

Novel arylazothiazoles and arylazo[1,3,4]thiadiazoles as potential antimicrobial and anticancer agents: synthesis, molecular modeling, and biological screening
In this study, we tested two novel series of 5-arylazo-2-hydrazonothiazoles 6a-g and 2-hydrazono[1,3,4]thiadiazoles 12a-c as antimicrobial and anticancer agents. These series were prepared from the reactions of 2-{1-[4-(2,4-dihydroxyphenylazo)phenyl]ethylidene}thiosemi-carbazide (3) with alpha-keto hydrazonoyl halides and N-aryl arenecarbohydrazonoyl halides. The structures of the newly synthesized compounds were elucidated by infrared, H-1 and C-13 nuclear magnetic resonance, and gas chromatography mass spectrometry spectral data. The antibacterial activity against two types of Gm +ve bacteria and, two types for Gm -ve bacteria, and the antifungal activity against four fungi microorganisms were evaluated by a well diffusion method for the synthesized compounds. Of these novel compounds, thiazole derivatives 6a-g showed mostly promising antibacterial activity against Gm +ve strains and antifungal activity compared to the reference drugs. A successful step was achieved to explain of their mode of action through molecular docking of the most active molecules at a target enzyme, CYP51. Moreover, the antiproliferative activity was tested against three human carcinoma cell lines [human colon carcinoma (HCT-116), human breast adenocarcinoma (MCF-7), and human liver carcinoma (HEPG-2)], showing promising anticancer activities compared to the doxorubicin drug. The data suggest that the arylthiazole scaffold derivatives 6a-g exhibited good antimicrobial and anticancer activities and might be used as leads for further optimization.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 7143-01-3 help many people in the next few years. Recommanded Product: Methanesulfonic anhydride.
