Reaction of quinaldine with 4,6-di(tert-butyl)-3-nitro-1,2-benzoquinone. Dependence of the outcome on the reaction conditions and a deeper insight into the mechanism

Heliyon, 2023
Condensation of quinaldine with 4,6-di (tert-butyl)-3-nitro-1,2-benzoquinone results in the formation of 5,7-di (tert-butyl)-2-(quinoline-2-yl)-1,3-tropolone, 5,7-di (tert-butyl)-4-nitro-2-(quinoline-2-yl)-1,3-tropolone, 3,3-dimethyl-2-(5-hydroxy-4-nitro-

S100A8/A9‐High Macrophages Activate Intestinal Fibroblasts via mCCL6/hCCL15‐CCR1 Axis to Drive Intestinal Fibrosis in Crohn's Disease

Advanced Science, EarlyView.
S100A8/A9‐high macrophages are markedly enriched in the stenotic intestinal tissue of patients with Crohn's disease. These profibrotic macrophages secrete mCCL6 in a STAT3‐dependent manner. mCCL6 and its human ortholog hCCL15 activate fibroblasts via the CCR1 receptor, thereby driving excessive collagen deposition.

Current developments of metal- and metalloid-based quinoline compounds as leishmanicidal agents

Frontiers in Chemistry
The quinoline moiety represents an important scaffold for the development of leishmanicidal agents. In particular, its hybridization with metal/metalloids has generated highly active compounds that are, in some cases, highly selective against ...

Hydrodenitrogenation of Quinoline and Acridine [PDF]

, 1977
The hydrodenitrogenation of quinoline and of acridine was studied in a batch autoclave reactor between 342 and 353/sup 0/C and between 500 and 2000 psig. The several commercial hydrotreating catalysts examined decreased in activity in the following order

Pd‐Catalyzed Asymmetric Dearomative Heck/Tsuji‐Trost Difunctionalization of Naphthalenes

Advanced Science, EarlyView.
We have developed a palladium‐catalyzed asymmetric dearomative Heck/Tsuji‐Trost 1,4‐difunctionalization reaction of naphthalenes, affording 4‐aminospirocyclohexene oxindole products bearing two remote chiral centers. Through the effect of the newly designed chiral sulfinamide phosphine ligand with large steric hindrance, side reactions are inhibited ...

SYNTHESIS AND ANTIMICROBIAL EVALUATION OF NOVEL 4-OXOTHIAZOLIDINYL QUINOLINES AND TRIAZOLOQUINOLINES [PDF]

Bulletin of Pharmaceutical Sciences. Assiut University, 1994
Different thiazolidinone derivatives have been prepared, attached either to 2- or 3-position of quinoline or attached to the 4-position of triazolo[4,3-a] quinoline. The antimicrobial activity of most of the prepared compounds has been studied.
