Synthesis and spectroscopic properties of 4-amino-1,8-naphthalimide derivatives involving the carboxylic group: a new molecular probe for ZnO nanoparticles with unusual fluorescence features

Autor: Laura Bekere, David Gachet, Vladimir Lokshin, Wladimir Marine, Vladimir Khodorkovsky

Publikováno v: Beilstein Journal of Organic Chemistry, Vol 9, Iss 1, Pp 1311-1318 (2013)

Of a series of 4-substituted 1,8-naphthalimides, fluorescent 4-(6-piperidinyl-1,3-dioxo-1H-benzo[de]isoquinolin-2(3H)-yl)benzoic acid (4) was found to be a sensitive molecular probe for ZnO nanoparticles. We investigated in detail one- and two-photon

Antifungal activity of styrylpyridinium compounds against Candida albicans

Autor: Simona Vaitkienė, Gunars Duburs, Laura Bekere, Neringa Kuliešienė, Sandra Sakalauskaitė, Brigita Vigante, L. Krasnova, Rimantas Daugelavičius

Publikováno v: Chemical biologydrug designREFERENCES. 97(2)

We synthesized a set of 13 new and earlier described styrylpyridinium compounds (N-alkyl styrylpyridinium salts with bromide or tosylate anions) in order to evaluate antifungal activity against C. albicans cells, to assay the possible synergism with
