Acute lung injury (ALI) is primarily driven by inflammation that severely impacts lung function. Novel 2-sulfonylindoles were recently shown to exhibit anti-inflammatory activity through the inhibition of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) production. Here, we synthesized 31 compounds which contained 2-sulfonylindole structure. The compounds 8a, 9g, 9h and 9k exhibited dose-dependent anti-inflammatory activity in vitro. Structural-activity relationship analysis revealed that the introduction of sulfonyl group in indole nucleus may be successful to obtain new anti-inflammatory structures and leads. The compounds 9h and 9k also decreased liposaccharide (LPS)-induced IL-6, IL-1beta and vascular cell adhesion molecule-1 (VCAM-1) mRNA expression, both in vitro and in an in vivo model of ALI. Furthermore, the compounds 9h and 9k at a high dose (20 mg/kg) significantly protected against LPS-induced ALI in mice. These results show that compounds 9h and 9k could be a promising lead structure for the treatment of ALI.

Amide bond formation is one of the most important reactions in organic chemistry because of the widespread presence of amides in pharmaceuticals and biologically active compounds. Existing methods for amides synthesis are reaching their inherent limits. Described herein is a novel rhodium-catalyzed three-component reaction to synthesize amides from organic azides, carbon monoxide, and (hetero)arenes via nitrene-intermediates and direct C?H functionalization. Notably, the reaction proceeds in an intermolecular fashion with N2 as the only by-product, and either directing groups nor additives are required. The computational and mechanistic studies show that the amides are formed via a key Rh-nitrene intermediate.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 10075-52-2 is helpful to your research. Reference of 10075-52-2

Based on the electronic properties of different hybridized oxygen atoms (sp3versus sp2) in the structure of O,O-acetals containing an enol ether moiety, the chemoselective formation of oxocarbenium ions was realized to furnish diversified chiral heterocyclic compounds with excellent stereoselectivities by reacting with different types of nucleophiles. Additionally, an unexpected intramolecular oxocarbenium ion transfer was also reported to form polycyclic products containing the O,O-acetal functional group.

Efficient syntheses of 4,5-, 5,6-, and 6,7-indolyne precursors beginning from commercially available hydroxyindole derivatives are reported. The synthetic routes are versatile and allow access to indolyne precursors that remain unsubstituted on the pyrrole ring. Indolynes can be generated under mild fluoride-mediated conditions, trapped by a variety of nucleophilic reagents, and used to access a number of novel substituted indoles. Nucleophilic addition reactions to indolynes proceed with varying degrees of regioselectivity; distortion energies control regioselectivity and provide a simple model to predict the regioselectivity in the nucleophilic additions to indolynes and other unsymmetrical arynes. This model has led to the design of a substituted 4,5-indolyne that exhibits enhanced nucleophilic regioselectivity.
