The structure–activity relationship and computational studies of 1,3-thiazole derivatives as cholinesterase inhibitors with anti-inflammatory activity

open access: yesComptes Rendus. Chimie, 2022
In our previous research, some screened 1,3-thiazole fragments were found to be potent by inhibiting LPS-induced TNF$\alpha $ and IL-8 release with IC50 values in the $\mu $M range without cytotoxic activity.

closo‐Carboranylanaloga von β‐Arylethylaminen: Direkte Synthese aus Alkenen mittels EnT‐Katalyse

open access: yesAngewandte Chemie, EarlyView.
Eine Strategie zur direkten Synthese von closo‐Carboranylanaloga medizinisch relevanter β‐Arylethylamine aus Alkenen wird vorgestellt. Die Reaktion basiert auf der erstmaligen Erzeugung von closo‐Carboranylradikalen mittels Energietransfer‐(EnT)‐Katalyse und ihren besonderen mechanistischen Merkmalen.

Neuere heterocyclische Zwischenprodukte für die Azokupplung durch Cyclisierung von Nitrilen

open access: yesCHIMIA, 1980
Two types of syntheses of heteroaromatic amines by cyclization of nitriles are described. It is dealt with the cyclization of nitriles by elemental sulphur yielding thiophenes and thiazoles and with some reactions of the resulting 2-amino-thiophene-3 ...

Synthesis and structure-physicochemical properties relationship of thiophene-substituted bis(5,4-d)thiazoles

open access: yesNova Biotechnologica et Chimica, 2018
Substituted thiophene-2-carbaldehydes 1a-dwere utilized in the synthesis of symmetrically substituted thiazolo[5,4-d]thiazoles 3a-d. Bis(5,4-d)thiazoles with thiophene core at the termini are the most employed in the chemistry of materials but exhibit ...

closo‐Carboranyl Analogs of β‐Arylethylamines: Direct Synthesis from Alkenes via EnT‐Catalysis

open access: yesAngewandte Chemie International Edition, EarlyView.
A strategy to directly synthesize closo‐carboranyl analogs of medicinal chemically important β‐arylethylamines from alkenes is reported. This reaction is enabled by the first formation of closo‐carboranyl radicals by energy transfer (EnT) catalysis and its unique mechanistic features.
