In the search for new fluorescent triphenylamine (TP) derivatives, we studied influence of position and substitution diverse heterocyclic substituents. A library 10 triphenylamines bearing either oxazoles or thiazoles pyridiniums, substituted at different positions has been developed. The approach is based on a convergent C−H activation reaction between pyridine-oxazoles pyridine-thiazoles di-i...

BACKGROUND The increasing prevalence of multi-drug resistant fungal infections has encouraged the search for new antifungal agents. Hydrazone derivatives always exhibited diversity activities, including antifungal, anti-inflammatory, anti-oxidation, anti-cancer activity. Regarding the heterocyclic moiety, 1,2,4-triazolo[4,3-a]pyridine derivatives also display broad activities, such as antifunga...

A series of 2,6-disubstituted pyridine derivatives were prepared from 2,6-diacetylpyridine or 2,6dicarbonyl pyridine dichloride as starting materials. Reaction of 2,6-diacetylpyridine 1 with hydroxylamine hydrochloride or different aromatic aldehydes afforded the corresponding 2,6-diacetylpyridine dioxime and 2,6-bis-[β -(2-thienyl)acryloyl]pyridine derivatives 2 and 3, respectively. Additional...

pathogenic infections and inflammation are very common ailments humans suffer. upsurge of resistant pathogens has impeded the antimicrobial drug development process in recent years and the search of new antimicrobial agents is clearly evident from the literature. in line with these developments the synthesis of n-substituted aryl-2-({4-[(substituted aryl carbamoyl) methyl]-5-(pyridin-4-yl)-4h-1...
