Eight organic-inorganic hybrid salts [(HL1)(SbCl4)] (1) (L1 = N,N-dimethylbenzylamine), [(HL2)2(ZnCl4)] (2) (L2 4-chlorobenzylamine), [(HL2)(L2)(CuCl3)(H2O)2] (3), [(HL3)2(Sb2OCl6)] (4) (L3 quinoline), [(HL4)4(Bi2Cl10)] (5) (L4 2-methylquinoline), [(HL5)(SbCl4)] (6) (L5 5,7-dimethyl-1,8-naphthyridine-2-amine), [(H2L6)(SbCl5)] (7) (L6 3,6-bis(imidazol-1-yl)pyridazine) and [(H2L7)2(CuBr4)2] · 7H2...

The aim of this study is to determine the changes in serum levels malondialdehyde and 8-hydroxy-2'-deoxyguanosine, as indicators oxidative stress, response periodontal treatment adyuvanted with topical doxycycline. Methods: Thirty four patients disease were studied (DOX group n=16; Control n=18), determining 8-hydroxy-2'-deoxyguanosine urine at baseline three months after non-surgical treatment...

Anesthetics are often used to immobilise fishes in research. Many chemicals have been tested in anesthetisation of fishes and each chemical has its own merits and demerits. In the present study, four anesthetics namely, 2-phenoxyethanol, quinaldine, MS-222, and benzocaine were selected to test the efficiency in anesthetisation of common carp Cyprinus carpia. Results indicated that the induction...

Our density functional theory (DFT)/time-dependent DFT calculations for the fluoride anion sensor, 5,7-dibromo-8-tert-butyldimethylsilyloxy-2-methylquinoline (DBM), suggested a different sensing mechanism from the experimentally proposed one (Chem. Commun., 2011, 47, 7098). Instead of the formation of fluoride-hydrogen-bond complex (DBMOHF) and excited-state proton transfer mechanism, the theor...

This article presents a complete and detailed study of synthesis, structural characterization, and possible applications of a new family of azanaphthoquinones as antimicrobial agents. A series of (alkoxy)phenylamino-chloro-2-methylquinoline-5,8-dione derivatives (3a-j, 3a', 3e') was prepared by regioselective nucleophilic substitution of 6,7-dichloro-2-methylquinoline-5,8-dione (1) with (alkoxy...

A 2,4-diarylquinoline derivative, 2-(4-chlorophenyl)-4-(3,4-dimethoxyphenyl)-6-methoxy-3-methylquinoline, was synthesized in a conventional two-step procedure from p-anisidine, p-chlorobenzaldehyde and methyl isoeugenol as available starting reagents through sequence of BF3·OEt2-catalyzed Povarov cycloaddition reaction/oxidative dehydrogenation aromatization processes under microwave irradiatio...
