Nanodroplet‐Array‐Plattform zur integrierten Synthese und Screening von MEK Inhibitoren: Ein miniaturisierter Ansatz für die frühe Pharmaforschung

open access: yesAngewandte Chemie, EarlyView.
Wir präsentieren eine Nanodroplet‐Array‐Plattform, die die Integration von Festphasensynthese, MALDI‐MS‐Analyse und zellbasiertem Screening von 325 potenziellen MEK‐Inhibitoren (Mitogen‐aktivierte‐Proteinkinase‐Kinase) in Nanoliter‐Volumina ermöglicht.

N-Butylpyrrolidinone as a dipolar aprotic solvent for organic synthesis [PDF]

open access: yes, 2016
Dipolar aprotic solvents such as N-methylpyrrolidinone (or 1-methyl-2-pyrrolidone (NMP)) are under increasing pressure from environmental regulation. NMP is a known reproductive toxin and has been placed on the EU “Substances of Very High Concern” list ...

Regulierung der Promiskuitiven Katalyse durch Substratinduzierte Transiente Assemblierung

open access: yesAngewandte Chemie, EarlyView.
Wir berichten über eine neuartige substratinduzierte transiente Koassemblierung zwischen einem kurzen lysinreichen Peptid und Fmoc‐Gly‐OH. Im aktivierten Zustand zeigt die Assemblierung eine promiskuitive katalytische Aktivität durch die Beschleunigung der Hydrolyse und der C═N‐Kondensationsreaktion.

1,3-Dipolar cycloadditions of 2-thio-3-chloroacrylamides with nitrile oxides and nitrones [PDF]

open access: yes, 2010
1,3-Dipolar cycloadditions of 2-thio-3-chloroacrylamides with nitrile oxides and nitrones is described. A series of novel isoxazolines are isolated from the nitrile oxide cycloadditions, whilst the isoxazolines generated from the nitrone cycloadditions ...

Diastereoselective synthesis of some novel benzopyranopyridine derivatives

open access: yesBeilstein Journal of Organic Chemistry, 2006
BackgroundThe formation of novel N-substituted-1,2,3,4-tetrahydro[1,3]-dioxolo-[6,7]-5H-[1]benzopyrano [3,4-c]pyridines were observed unexpectedly during the acid-mediated ketal removal of ethylenedioxy ketal protected 4-piperidones.

The Synthesis and Biological Activity of 1-Alkyl-4-(3-azacyclobenzoyl)-5-hydroxypyrazole Herbicides

open access: yesCHIMIA, 2003
The benzoylpyrazoles belong to a class of herbicides that inhibit the enzyme 4-hydroxy-phenylpyruvate dioxygenase (HPPD). This mode of action is characterized by bleaching due to the disruption of plastoquinone and ?-tocopherol biosynthesis ...

Diels-alder cycloaddition in the synthesis of 1-azafagomine, analogs, and derivatives as glycosidase inhibitors [PDF]

open access: yes, 2012
This comprehensive review deals with the synthesis of 1-azafagomine, analogs, and derivatives having the Diels-Alder cycloaddition as the key step. Most of the compounds referred are racemic or have been resolved by lipase transesterification.
