Complexes containing the anions of 5-benzoylamido-1,3,4-thiadiazole-2-sulfonamide and 5-(3-nitro-benzoylamido)-1,3,4-thiadiazole-2-sulfonamid as ligands, and V(IV); Cr(III); Fe(III); Co(II); Ni(II); Cu(II) and Ag(I) were synthesized and characterized by standard procedures (elemental analysis; IR, electronic, and EPR spectroscopy; TG, magnetic and conductimetric measurements). The original sulf...

A number of imidazo[2,1-b][1,3,4]thiadiazole derivatives having alkyl and aryl moieties attached to positions 2 and 6 of imidazo[2,1-b][1,3,4]thiadiazole nucleus, respectively, were prepared and characterized by IR, NMR and mass spectroscopy. Antiinflammatory activity was evaluated by carrageenan-induced rat paw edema assay. By 5th hours, all compounds demonstrated anti-inflammatory activity si...

In the title compound, C(4)H(6)N(2)OS(2), the dihedral angle between the five-membered heterocyclic ring and the plane of the eth-oxy group is 4.9 (2)°. The 1,3,4-thiadiazole-2-thione unit is planar, with an r.m.s. deviation of 0.011 Å from the corresponding squares plane defined by the seven constituent atoms. In the crystal, pairs of N-H⋯S hydrogen bonds link the mol-ecules into inversion dim...

Several new fluorinated quinazolinone derivatives were prepared and evaluated for in vitro anti-inflammatory activity. The molecular modelling study was performed for compounds 4, 8, 9, 10 and 13. The tested compounds showed strong interactions at the COX-2 binding sites. Compounds 8, 13, 9, and 10 containing triazole, thiadiazole, and oxadiazole rings showed the highest in vitro anti-inflammat...

Anionic polyfluorene and oligofluorene derivatives were synthesized and utilized as organic dye sensitizers in dye sensitized solar cells to show a maximum power conversion efficiency of 1.39%.

A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...

BACKGROUND Many heterocyclic compounds containing thiazole or 1,3,4-thiadiazole ring in their skeletons have been reported to possess various pharmacological activities especially anticancer activities. RESULTS 4-Methyl-2-phenylthiazole-5-carbohydrazide (2) was used as a synthon to prepare 2-(4-methyl-2-phenylthiazole-5-carbonyl)-N-phenylhydrazinecarbothioamide (3) and 2-(2-(4-methyl-2-phenyl...
