The title compound, C(15)H(11)N(3)OS(2), was synthesized from benzoyl thio-cyanate and 2-amino-benzothia-zole in dry acetone. The thio-urea group is in the thio-amide form. The mol-ecules are stabilized by two inter-molecular C-H⋯S and C-H⋯O hydrogen bonds. Intra-molecular N-H⋯O hydrogen bonding results in a pseudo-S(6) planar ring with dihedral angles of 11.23 and 11.91° with the benzothiazole...

Protein aggregation into amyloid deposits and oxidative stress are key features of many neurodegenerative disorders including Parkinson's and Alzheimer's disease. We report here the creation of four highly sensitive bifunctional fluorescent probes, capable of H2O2 and/or amyloid aggregate detection. These bifunctional sensors use a benzothiazole core for amyloid localization and boronic ester o...

Activity of 2-alkylthio-6-aminobenzothiazoles and their 6-A/-substituted derivatives (3-(2-alkylthio6-benzothiazolylaminomethyl)-2-benzothiazolinethiones and 3-(2-alkylthio-6-benzothiazolylaminomethyl)-6-bromo-2-benzothiazolinones) concerning photosynthesis inhibition in algae Chlorella vulgaris and in spinach chloroplasts has been correlated with lipophilicity and dipóle moments of the effecto...

The title compounds 6aâj, 2-[(6-methyl-1,3-benzothiazol-2-yl)amino]-N-[2-(substituted phenyl/furan-2-yl)-4-oxo-1,3-thiazolidin-3-yl]nicotinamides, were prepared from 2-chloropyridine-3-carboxylic acid (1) and 2-amino-6-methyl-benzothiazole (2) by known methods. All the compounds have been established by IR, (1)H NMR, (13)C NMR and elemental analyses. The in vitro antimicrobial screening of the ...

Saccharin (o-sulfobenzimide; 1,2-benzothiazole-3(2H)-one 1,1 dioxide; Hsac, Figure 1) is one of the best known and most widely used artificial sweetening agents. Initially, investigation of the interaction of saccharin with different biologically relevant cations attracted great interest due to the suspected carcinogenicity of this compound which, notwithstanding, was recently definitively rule...

A series of novel guanidine derivatives were synthesized in three steps and their anti-inflammatory activities in vitro and in vivo evaluated. 2-Aminopyridin-3-ol (1) was reacted with thiophosphoryl chloride (2) to give a monochloride (3). It was further reacted with cyanamide to afford the corresponding cyanamine (4), which was subsequently reacted with different heterocyclic amines to form th...

An efficient synthesis of highly functionalized chiral β-amino ester derivatives containing benzothiophene and benzothiazole moieties is developed by a Mannich-type reaction using a cinchona alkaloid-derived thiourea catalyst. The desired products were obtained in good yields and high enantioselectivities (~86% yield, >99% ee) using to the optimized reaction conditions. The synthesized compound...

The novel ligand 2-[2'-(6-methoxybenzothiazolyl)azo]-3,5-dimethyl benzoic acid (6-MBTAMB), derived from 2-amino-6-methoxy benzothiazole, has been used to synthesize a series of new metal complexes Ag(I), Pt(IV) and Au(III). were characterized by elemental analyses (CHNS), molar conductivity, crystal structure (XRD), spectroscopic techniques: FT-IR, 1H NMR, 13C UV–Vis, mass spectra, thermal anal...
