Gujraty, Kunal V. published the artcileThiol-Mediated Anchoring of Ligands to Self-Assembled Monolayers for Studies of Biospecific Interactions, Synthetic Route of 359860-27-8, the publication is Langmuir (2006), 22(24), 10157-10162, database is CAplus and MEDLINE.

The authors report a method to immobilize thiol-containing ligands onto self-assembled monolayers (SAMs) of alkanethiolates presenting chloracetylated hexa(ethylene glycol) groups. The chloroacetyl groups react with thiols under mild basic conditions, enabling the stable immobilization of biol. active ligands in a well-defined orientation. These SAMs on gold are well suited for studies of biospecific interactions of immobilized ligands with proteins and cells. As a demonstration, the authors functionalized these SAMs with thiol-containing derivatives of biotin and benzene sulfonamide and observed the specific binding of Neutravidin and carbonic anhydrase, resp. The authors also used this method to generate mixed SAMs presenting the Arg-Gly-Asp (RGD) peptide sequence and demonstrated the integrin-mediated adhesion of fibroblast cells to these SAMs. This approach would allow the immobilization of proteins and other sensitive biomols. and ligands for a wide variety of applications in biotechnol.

Kuramochi, Kouji published the artcileSynthesis of neoechinulin A and derivatives, HPLC of Formula: 359860-27-8, the publication is Synthesis (2008), 3810-3818, database is CAplus.

Neoechinulin A isolated from Eurotium rubrum showed cytoprotective activity against peroxynitrite generated from SIN-1 [3-(4-morpholinyl)sydnonimine.HCl] in PC12 cells. As the authors are interested in this biol. activity, they synthesized neoechinulin A and its derivatives The isolation of natural neoechinulin A and B, a total synthesis of (-)-neoechinulin A, and the determination of the absolute configuration of natural neoechinulin A was reported. In addition, syntheses of neoechinulin A derivatives, including a biotinylated neoechinulin A derivative, which will be useful for identification of the binding proteins of neoechinulin A, were described.

Rein, Jonas published the artcileUnlocking the Potential of High-Throughput Experimentation for Electrochemistry with a Standardized Microscale Reactor, Recommanded Product: 2-(2-Methyl-1H-imidazol-1-yl)pyridine-4-carbonitrile, the publication is ACS Central Science (2021), 7(8), 1347-1355, database is CAplus and MEDLINE.

Organic electrochem. has emerged as an enabling and sustainable technol. in modern organic synthesis. Despite the recent renaissance of electrosynthesis, the broad adoption of electrochem. in the synthetic community, and especially in industrial settings, has been hindered by the lack of general, standardized platforms for high-throughput experimentation (HTE). Herein, we disclose the design of the HTe^–Chem, a high-throughput microscale electrochem. reactor that is compatible with existing HTE infrastructure and enables the rapid evaluation of a broad array of electrochem. reaction parameters. Utilizing the HTe^–Chem to accelerate reaction optimization, reaction discovery, and chem. library synthesis is illustrated using a suite of oxidative and reductive transformations under constant current, constant voltage, and electrophotochem. conditions.

Wang, Ting-Hsuan published the artcileNickel-Catalyzed Heteroarenes Cross Coupling via Tandem C-H/C-O Activation, Synthetic Route of 2622-67-5, the publication is ACS Catalysis (2018), 8(12), 11368-11376, database is CAplus.

Inert aryl Me ethers as coupling components via C-O activation have been established with a Ni catalyst for C-H activation of heteroarene. The key to simultaneous C-H/C-O bond activation is the use of sterically demanding o-tolylMgBr. The protocol is effective for a wide scope of substrates including naphthyl Me ethers, anisoles, and a variety of other heteroarene derivatives Detailed mechanistic studies indicated that the C-O cleavage is assisted via synergistic effect of nickel and Grignard reagent in this C-H/C-O reaction, which is supported by DFT calculation At this stage, single-electron transfer can be ruled out as a main operative process for this tandem strategy.
