Construction of Spiro-tetrahydroquinolines via Intramolecular Dearomatization of Quinolines: Free of a Preinstalled Activation Group
摘要:
A highly efficient synthesis of spiro-tetrahydroquinolines (up to 99% yield) has been realized via cascade hydrogenative dearomatization of quinollne and Intramolecular aza-Friedel-Crafts alkylation reaction.
Discovery of 2-oxo-1,2-dihydrobenzo[cd]indole-6-sulfonamide derivatives as new RORγ inhibitors using virtual screening, synthesis and biological evaluation
Retinoic acid receptor-related orphan receptor γ (RORγ), a member of the nuclear hormone receptor superfamily, is a promising therapeutic target for treating Th17-mediated autoimmune diseases. We performed structure-based virtualscreening targeting the RORγ ligand-binding domain. Among the tested compounds, s4 demonstrated RORγ antagonistic activities with micromolar IC50 values in both an AlphaScreen

to elucidate the unknown binding modes of fragments. An enzyme substrate with well-characterized binding was used as a starting point, and the relative binding modes of modified fragments derived from ILOE observations were used to guide the fragmentlinking, leading to a potent inhibitor of our model system, Mycobacterium tuberculosis pantothenate synthetase, a potential drug target. We have supported

potent inhibitors of the title enzyme. X‐ray crystallography and isothermal titration calorimetry guided the systematic elaboration of fragments identified from biophysical screens. The excellent inhibitor shown in the enzyme active site on the right was formed by connection of the lead fragments (left) with an acyl sulfonamide linker and resembles the best inhibitor discovered by the fragment‐growing

A stereoselective synthetic route to chiral C3-spirooxindole- and C2-spiropseudoindoxyl-pyrrolidines was accomplished by an enantioselective organocatalyzed Pictet-Spengler reaction of tryptamines and isotryptamines followed by a diastereoselective oxidativerearrangement using eco-friendly oxidants (i. e., NaOCl ⋅ 5H2O and Oxone®). This sequential reaction enables rapid access to chiral C3-spirooxindole-
