Retinoic acid receptor related orphan receptor γt (RORγt), identified as the essential functional regulator of IL-17 producing Th17 cells, is an attractive drug target for treating autoimmune diseases. Starting from the reported GSK2981278 (Phase II), we structurally modified and synthesized a series of 2H-chromone-4-one based sulfonamide derivatives as novel RORγt inverse agonists, which significantly improved their human metabolic stabilities while maintaining a potent RORγt inverse agonist profile. Efforts in reducing the lipophilicity and improving the LLE values led to the discovery of c9, which demonstrated potent RORγt inverse agonistic activity and consistent metabolic stability. During in vivo studies, oral administration of compound c9 exhibited a robust and dose-dependent inhibition of IL-17A cytokine expression and significantly lessened the skin inflammatory symptoms in the mouse imiquimod-induced skin inflammation model. Docking analysis of the binding mode revealed that c9 can suitably occupy the active pocket, and the introduction of the morpholine pyridine group can interact with Leu396, His479, and Cys393. Thus, compound c9 was selected as a preclinical compound for treating Th17-driven autoimmune diseases.

Palladium-Catalyzed Tandem Carbonylative Diels-Alder Reaction for Construction of Bridged Polycyclic Skeletons
Wang, Siyuan,Zhou, Yangkun,Huang, Hanmin
, p. 2125 - 2129 (2021/04/05)
A palladium-catalyzed tandem carbonylative lactonization and Diels-Alder cycloaddition reaction between aldehyde-tethered benzylhalides and alkenes has been developed. A range of alkenes and aldehyde-tethered benzylhalides bearing different substituents can be successfully transformed into the corresponding bridged polycyclic compounds in good yields. This strategy provides a unique approach to complex lactone-containing bridged polycyclic compounds.

Isoindolinones are ubiquitous structural motifs in natural products and pharmaceuticals. Establishing an efficient method for structural modification of isoindolinones could significantly facilitate new drug development. Herein, we describe copper-promoted direct amidation of isoindolinone scaffolds mediated by sodium persulfate. The method exhibits mild reaction conditions and high site-selectivity, and enables the structural modification of the drug indobufen ester with various amides with yields of 49 to 98%. It is also gram-scalable. Additionally, the reaction mechanism appears to involve a radical and a carbocationic pathway.

Paragraph 0062-0063, (2021/04/03)
The invention provides a photocatalytic continuous bromination method. The method comprises the following steps: carrying out a first-stage photocatalytic continuous bromination reaction on a materialcontaining an aromatic substrate with a structural general formula I and a bromination reagent in a first continuous illumination reactor to form a first continuous system; overflowing the obtained first continuous system into a second continuous illumination reactor for a second-stage photocatalytic continuous bromination reaction to form a second continuous system; and purifying the second continuous system, wherein the structural general formula I is shown in the specification, R is selected from any one of carboxyl, ester group, NO2, CN, C1 to C8 alkyl and alkoxy, and R1 is C1 to C8 alkyl; n is 1 or 2; X is N or C, and the bromination reagent is Nbromo succinimide or dibromohydantoin. According to the bromination reagent, the selectivity of a product is improved, so the yield of the product is improved; the photocatalytic continuous bromination reaction of the two stages effectively relieves the reaction heat accumulation, and enhances the yield of the target product.
