TL;DR: Bacterial activity of acyl-hydrazone and its complexes were studied against gram-positive bacteria: Staphylococcus aureus, Bacillus subtilis and gram-negative bacteria: Pseudomonas aeruginosa, Escherichia coli by using minimum inhibitory concentrations (MICs) method.

TL;DR: In this article, the crystal structure of 1-phenyl-2,3-dimethyl-4-(N-3-formyl-6-methyl-chromone)-3-pyrazolin-5-one (HL) has been determined by X-ray diffraction studies, as well as the one of its copper(II) complex [CuL(OAc)]·CH3OH which contains an anionic ligand and an acetate in the coordination sphere of the metal.

TL;DR: The formation of thiazolo[3,2-b][1,2,4]triazole 6, 7 was confirmed in detriment of [2,3-c] isomeric compounds (forms II); the potential antibacterial effects of the synthesized compounds were investigated using standard bacterial strains.

TL;DR: Some new intermediates from thiosemicarbazide class were afforded by the reaction of 4-(4-X-phenylsulfonyl)benzoic acids hydrazides (X=H, Br) 1a,b with 4-trifluoromethoxyphenyl or 3,4,5-trimethoxyl isothiocyanate.

TL;DR: A series of Mannich bases of 4-substituted 5-[4-(4-X-phenylsulfonyl)phenyl]-2, 4-dihydro-3H-1,2,4-triazole-3-thiones, X=H, Cl, Br, 3 and 5 were synthesized and characterized on the basis of IR, NMR and elemental analyses.
