NorA Efflux Pump Inhibitors: Expanding SAR Knowledge of Pyrazolo[4,3-c][1,2]benzothiazine 5,5-Dioxide Derivatives [PDF]

open access: yesArchiv der Pharmazie, Volume 358, Issue 5, May 2025.
Antimicrobial resistance (AMR) represents a significant global concern, driven by the overuse of antibiotics. One of the principal mechanisms contributing to AMR is the activity of microbial efflux pumps (EPs), which expel diverse antibiotics out of ...

Synthesis of 3-Aminohydantoiny;-1,2-benzothiazine Derivatives [PDF]

open access: yesBulletin of the Korean Chemical Society, 2002
By the application of these methods, 1,2-benzothi-azine derivatives with 3-aminohydantoin moiety were pre-pared. Here, we report the synthesis of several new 3-aminohydantoinyl-1,2-benzothiazine derivatives and pro-pose an another mechanism of the cyclization to thehydantoins.3-Aminohydantoins 3a-d were prepared through cycli-zation of the condensation

Phenolic Polymers as Model Melanins

open access: yesMacromolecular Chemistry and Physics, Volume 224, Issue 14, July 2023., 2023
Polymerization of a variety of phenolic monomers (CAT, DOPA, or HGA) yields conjugated polymers (polyCATs, polyDOPAs, or polyHGA‐HS, respectively) which are simplified versions of biologically generated melanins. Their chemical, paramagnetic, and electrical properties are analyzed to assess if there may be a correlation between the functional groups ...

Neuromelanins in brain aging and Parkinson's disease: synthesis, structure, neuroinflammatory, and neurodegenerative role

open access: yesIUBMB Life, Volume 75, Issue 1, Page 55-65, January 2023., 2023
Abstract Neuromelanins are compounds accumulating in neurons of human and animal brain during aging, with neurons of substantia nigra and locus coeruleus having the highest levels of neuromelanins. These compounds have melanic, lipid, peptide, and inorganic components and are contained inside special autolysosomes.

Benzo[c][1,2]thiazine‐Based Analogs in the Inverse Electron Demand [4+2] Hetero Diels‐Alder Reaction with Glycals: Access to Tetracyclic Fused Galactose and Fucose Derivatives

open access: yesEuropean Journal of Organic Chemistry, Volume 2022, Issue 43, November 18, 2022., 2022
The N‐substituted‐3‐thioxo‐benzo[c][1,2]thiazin‐4‐one‐2,2‐dioxides are an original class of highly reactive electron‐poor heterodienes that allow easy access to unprecedented benzo‐thiazine bearing galactose and fucose derivatives in a remarkably selective way. Abstract The synthesis and reactivity in an [4+2] inverse electron demand hetero Diels‐Alder
