A series of novel and highly active acetylcholinesterase and butyrylcholinesterase inhibitors derived from substituted benzothiazoles containing an imidazolidine-2,4,5-trione moiety were synthesized and characterized. The molecular structure of 1-(2,6-diisopropyl-phenyl)-3-[(1R)-1-(6-fluoro-1,3-benzothiazol-2-yl)ethyl]-imidazolidine-2,4,5-trione (3g) was(More)
A series of novel cholinesterase inhibitors based on 2-substituted 6-fluorobenzo[d]thiazole were synthesised and characterised by IR, (1)H, (13)C and (19)F NMR spectroscopy and HRMS. Purity was checked by elemental analyses. The novel carbamates were tested for their ability to inhibit acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). The(More)
In the current study, sixteen novel derivatives of (R)-1-(6-fluorobenzo[d]thiazol-2-yl)ethanamine were synthesized as acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitors. Chemical structures together with purity of the synthesized compounds were substantiated by IR, (1)H, (13)C, (19)F NMR, high resolution mass spectrometry and elemental(More)
A series of novel 1-[(1R)-1-(6-fluoro-1,3-benzothiazol-2-yl)ethyl]-3-substituted phenyl amides was synthesized by the condensation reaction of (1R)-1-(6-fluoro-1,3-benzothiazol-2-yl)ethanamine with substituted benzoyl chlorides under mild conditions. Their structures were confirmed by 1H NMR, 13C NMR and 19F NMR spectra, elemental analyses and in three(More)
A method for the separation of enantiomers of leucine and phenylalanine benzothiazole derivatives as potential antimicrobial agents was developed using capillary zone electrophoresis with a dual cyclodextrin (CD) system. The best resolution of enantiomers was achieved in 100 mmol/L phosphate background electrolyte (pH 3.5) with the dual CD system consisting(More)
The reactivity of (L(CN))(2)Sn (1) (where L(CN) is 2-(N,N-dimethylaminomethyl)phenyl-) towards various substrates containing E–Cl bond(s) has been studied (E = C, Si, Ge and Sn). Alkyl chlorides like chloroform or dichloromethane reacts with 1 to form (L(CN))(2)SnCl(2) and unidentified by-products in poor yields. The reaction of benzoyl chloride with 1 at(More)
A new series of 1-[(1R)-1-(6-fluoro-1,3-benzothiazol-2-yl)ethyl]-3-substituted phenyl diamides were synthesized in vitro as potential antifungal agents. Chemical structures of the synthesised compounds were substantiated by IR, 1H, 13C, 19F nuclear magnetic resonance spectra, high resolution mass spectrometry, elemental analysis and also by X-ray(More)
The present paper deals with the preparation and characterization of a conjugate of isoniazid (INH) with the block copolymer methoxypoly(ethylene glycol)-b-poly(L-lysine) (mPEG-b-PLL). The structure of the conjugate (mPEG-b-PLL-INH) was verified by means of (1)H NMR, GPC, infrared spectroscopy, elemental analysis and powder X-ray diffraction. The conjugate(More)
