Dihydropyridine-fused and pyridine-fused coumarins: Reduction on a glassy carbon electrode in dimethylformamide
(2012)
In this study, two series of dihydropyridine-fused and pyridine-fused coumarins were synthesised and electrochemically characterised in aprotic medium. In both series, the most easily reducible groups were the endocyclic ...
Two new O-geranyl coumarins from the resinous exudate of Haplopappus multifolius
(Elsevier, 2004)
From the resinous exudate of leaves of Haplopappus multifolius two new coumarins were isolated and assigned the structures 6-hydroxy-7-(5′- hydroxy-3′,7′-dimethylocta-2′,6′-dien)-oxycoumarin (1) and 6-hydroxy-7-(7′-hydro ...
Gastroprotective activity of synthetic coumarins: Role of endogenous prostaglandins, nitric oxide, non-protein sulfhydryls and vanilloid receptors
(Elsevier, 2016)
Natural or synthetic coumarins showed gastroprotective and antiulcer activity in animal models. In this study, we have synthetized twenty coumarins using classic methods to evaluate their gastroprotective effects on the ...
Synthesis and electrochemical oxidation of hybrid compounds:dihydropyridine-fused coumarins
(Elsevier, 2013)
tIn this paper, a series of six dihydropyridine-fused coumarins were synthesized and electrochemicallycharacterized in dimethylformamide (DMF).Dihydropyridine ring oxidation on glassy carbon electrode (GCE) for condensed ...
Diterpenes and 5-methyl coumarin derivatives from Gypothamnium pinifolium and Plazia daphnoides
(1988)
The aerial parts of Gypothamnium pinifolium afforded, in addition to three known 5-methyl coumarins, four new 5-methyl coumarins and two closely related coumaranones. Furthermore, seven diterpenes, all derived from ...
Synthesis and electrochemical oxidation of hybrid compounds: Dihydropyridine-fused coumarins
(2014)
In this paper, a series of six dihydropyridine-fused coumarins were synthesized and electrochemically characterized in dimethylformamide (DMF). Dihydropyridine ring oxidation on glassy carbon electrode (GCE) for condensed ...
Facing Chagas' Disease: Trypanocidal Properties of New Coumarin-chalcone Scaffolds
(Bentham Science, 2016)
With the aim of finding new chemical entities based on coumarin and chalcone scaffolds, new hybrid compounds 2-5 were designed and synthesized. The trypanocidal activity of these compounds was tested against the epimastigote, ...
Design and synthesis of a new coumarin-based 'turn-on' fluorescent probe selective for Cu +2
(2012)
The novel coumarin-based 'turn-on' fluorescent probe (E)-3-(2,5- dimethoxybenzylideneamino)-7-hydroxy-2H-chromen-2-one (MGM) was designed, synthesized, and characterized. This compound shows high selectivity for Cu +2, ...
New Copper(I) complex with a coumarin as ligand with antibacterial activity againstFlavobacterium psychrophilum
(MDPI, 2020)
A new copper (I) complex, [Cu(NN1)(2)](ClO4)(,)was synthesized, where NN(1)was a imine ligand 6-((quinolin-2-ylmethylene)amino)-2H-chromen-2-one obtained by a derivatization of natural compound coumarin. The structural ...
Synthesis of coumarin derivatives as fluorescent probes for membrane and cell dynamics studies
(Elsevier, 2014)
Three coumarin-derived fluorescent probes, 3-acetyl-7-[(6-bromohexyl)oxy]-2H-chromen-2-one (FM1),
7-[(6-bromohexyl)oxy]-4-methyl-2H-chromen-2-one (FM2) and ethyl 2-{7-[(6-bromohexyl)oxy]-2-oxo-
2H-chromen-4-yl}acetate ...
