Herein, the development of novel tricoordinate Au(I) catalysts supported by N,N-bidentate ligands and ligated by phosphine or arsine ligands for C-H functionalization without external oxidants to form biaryls with no homocoupling was reported. The unsym. character of the Au(I) catalyst was critical to facilitating this necessary orthogonal transformation. This study unveils yet another potential of Au(I) catalysis in biaryl synthesis. The experimental process involved the reaction of 3-Iodophenol(cas: 626-02-8Electric Literature of C6H5IO)

3-Iodophenol(cas: 626-02-8) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom.

The title of the article was 《Synthesis and biological evaluation of novel rhodanine-based structures with antiviral activity towards HHV-6 virus》.Related Products of 626-02-8 The author mentioned the following in the article:

An increased awareness of diseases associated with Human herpesvirus 6 (HHV-6) infection or reactivation has resulted in a growing interest in the evaluation of the best treatment options available for the clin. management of HHV-6 disease. However, no compound has yet been approved exclusively for HHV-6 infection treatment. For this reason, the identification of anti-HHV6 compounds provides a valuable opportunity for developing efficient antiviral therapies. A possible target for antiviral drugs is the virus-cell fusion step. In this study, we synthesized potential fusion intermediates inhibitors based on the rhodanine structure. The obtained derivatives were tested for cytotoxicity and for antiviral activity in human cells infected with HHV6. Level of infection was monitored by viral DNA quantification at different time points up to 7 days post infection. Among the synthesized derivatives, 9e showed a significative inhibitory effect on viral replication that lasted over 7 days, probably attributable to the particular combination of hydrophilic and hydrophobic substituents to the rhodanine moiety. Our results support the use of these amphipathic fusion inhibitors for the treatment of HHV-6 infections.

Kitadai, Norio; Nakamura, Ryuhei; Yamamoto, Masahiro; Okada, Satoshi; Takahagi, Wataru; Nakano, Yuko; Takahashi, Yoshio; Takai, Ken; Oono, Yoshi published an article in 2021. The article was titled 《Thioester synthesis through geoelectrochemical CO2 fixation on Ni sulfides》, and you may find the article in Communications Chemistry.Application In Synthesis of 1-Iodopyrrolidine-2,5-dione The information in the text is summarized as follows:

A prevailing scenario of the origin of life postulates thioesters as key intermediates in protometabolism, but there is no exptl. support for the prebiotic CO2 fixation routes to thioesters. Here we demonstrate that, under a simulated geoelectrochem. condition in primordial ocean hydrothermal systems (-0.6 to -1.0 V vs. the standard hydrogen electrode), nickel sulfide (NiS) gradually reduces to Ni0, while accumulating surface-bound carbon monoxide (CO) due to CO2 electroreduction The resultant partially reduced NiS realizes thioester (S-Me thioacetate) formation from CO and methanethiol even at room temperature and neutral pH with the yield up to 35% based on CO. This thioester formation is not inhibited, or even improved, by 50:50 coprecipitation of NiS with FeS or CoS (the maximum yields; 27 or 56%, resp.). Such a simple thioester synthesis likely occurred in Hadean deep-sea vent environments, setting a stage for the autotrophic origin of life.
