Curreli, Francesca; Kwon, Young Do; Zhang, Hongtao; Scacalossi, Daniel; Belov, Dmitry S.; Tikhonov, Artur A.; Andreev, Ivan A.; Altieri, Andrea; Kurkin, Alexander V.; Kwong, Peter D.; Debnath, Asim K. published the artcile< Structure-Based Design of a Small Molecule CD4-Antagonist with Broad Spectrum Anti-HIV-1 Activity>, HPLC of Formula: 20582-55-2, the main research area is antiviral HIV AIDS.

Earlier the authors reported the discovery and design of NBD-556 and their analogs which demonstrated their potential as HIV-1 entry inhibitors. However, progress in developing these inhibitors has been stymied by their CD4-agonist properties, an unfavorable trait for use as drug. Here, the authors demonstrate the successful conversion of a full CD4-agonist (NBD-556) through a partial CD4-agonist (NBD-09027), to a full CD4-antagonist I (NBD-11021) by structure-based modification of the critical oxalamide mid-region, previously thought to be intolerant of modification. I showed unprecedented neutralization breath for this class of inhibitors, with pan-neutralization against a panel of 56 Env-pseudotyped HIV-1 representing diverse subtypes of clin. isolates (IC50 as low as 270 nM). The cocrystal structure of NBD-11021 complexed to a monomeric HIV-1 gp120 core revealed its detail binding characteristics. The study is expected to provide a framework for further development of NBD series as HIV-1 entry inhibitors for clin. application against AIDS.

There is significant interest in the development of process routes for active pharmaceutical ingredients using C-H arylation methodol. An efficient and practical synthetic route for febuxostat, which is the first non-purine-type xanthine oxidase inhibitor, was established via palladium- and copper-catalyzed C-H arylation of thiazole with aryl bromide. The catalyst loading was reduced to 0.1 mol % for the intermol. C-H arylation, and a three-step synthesis produced febuxostat in 89% overall yield with excellent selectivity.

Hosseini-Sarvari, Mona; Hosseinpour, Zeinab; Koohgard, Mehdi published the artcile< Visible light thiocyanation of N-bearing aromatic and heteroaromatic compounds using Ag/TiO2 nanotube photocatalyst>, Safety of 2-Amino-4-(3-nitrophenyl)thiazole, the main research area is aryl thiocyanate preparation green chem visible light irradiation; pyrrole aniline aminothiazole thiocyanation photocatalyst.

In this study, Ag/TiO2 nanotubes (Ag/TNT) were synthesized via simple hydrothermal process, and this photocatalyst was successfully exploited in thiocyanation reactions at room temperature under visible light irradiation Four classes of important heterocyclic compounds including indole, aniline, pyrrole and 2-aminothiazole derivatives via Ag/TNT treated with ammonium thiocyanate formed the corresponding thiocyano compounds in moderate to excellent yields. Plasmonic property and catalytic performance of Ag nanoparticles (which mainly deposited on the surface of TNT) in absorbing species containing sulfur atoms were key components for the reactions to proceed. This potent, simple and versatile protocol reported for the first time afforded thiocyanation reactions of aniline, pyrrole and 2-aminothiazole derivatives under visible light. The reactions proceeded through a radical pathway by applying air mol. oxygen as a low-cost and environmentally friendly terminal oxidant.

Fretaud, Maxence; Descamps, Delphyne; Laubreton, Daphne; Rameix-Welti, Marie-Anne; Eleouet, Jean-Francois; Larcher, Thibaut; Galloux, Marie; Langevin, Christelle published the artcile< New look at RSV infection: tissue clearing and 3D imaging of the entire mouse lung at cellular resolution>, Product Details of C11H8N2O3S2, the main research area is mouse lung RSV infection cellular resolution tissue clearing imaging; 3D imaging of lungs; RSV infection; RSV tropism; inclusion bodies; tissue clearing; viral pathophysiology.

Respiratory Syncytial Virus (RSV) is the major cause of severe acute respiratory tract illness in young children worldwide and a main pathogen for the elderly and immune-compromised people. In the absence of vaccines or effective treatments, a better characterization of the pathogenesis of RSV infection is required. To date, the pathophysiol. of the disease and its diagnosis has mostly relied on chest X-ray and genome detection in nasopharyngeal swabs. The development of new imaging approaches is instrumental to further the description of RSV spread, virus-host interactions and related acute respiratory disease, at the level of the entire lung. By combining tissue clearing, 3D microscopy and image processing, we developed a novel visualization tool of RSV infection in undissected mouse lungs. Whole tissue anal. allowed the identification of infected cell subtypes, based on both morphol. traits and position within the cellular network. Furthermore, 3D imaging was also valuable to detect the cytoplasmic viral factories, also called inclusion bodies, a hallmark of RSV infection. Whole lung clearing and 3D deep imaging represents an unprecedented visualization method of infected lungs to allow insight into RSV pathophysiol. and improve the 2D histol. analyses.
