In the present investigation, two novel series of 2-[3-(4-chlorophenyl)propan-3-one]-5-(substituted phenyl)-1,3,4-oxadiazole and 2-[3-(4-ethylphenyl)propan-3-one]-5-(substituted phenyl)-1,3,4-oxadiazole were synthesized and tested for their antiinflammatory, analgesic, ulcerogenic and antibacterial actions. A fair number of compounds were found to have very good antiinflammatory activity in car...

a series of five-membered heterocyclic rings were synthesized by the reaction between benzoyl chloride and various chlolro-nitro-benzoyl chlorides and semi carbazide to form (c1-c7) compounds and was tested for their anti-inflammatory activity determined by rat-paw-oedema method. all the synthesis compounds have been characterized by 1hnmr, ir and mass spectral data. the compounds were purified...

In the title compound, C(16)H(14)N(2)O(3), the essentially planar 1,3,4-oxadiazole ring [maximum deviation = 0.0021 (11) Å] is inclined at dihedral angles of 8.06 (6) and 11.21 (6)° with respect to the two benzene rings; the dihedral angle between the latter rings is 11.66 (5)°. In the crystal, short inter-molecular C⋯O inter-actions [2.9968 (15) Å] connect adjacent mol-ecules into chains propa...

In the title compound, C(10)H(8)Cl(2)N(2)O(2)S·0.5H(2)O, the atoms in the oxadiazole ring are essentially coplanar (r.m.s. deviation 0.010 Å). The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds involving the water mol-ecule, which is situated on an a twofold rotation axis, and two organic mol-ecules, leading to a thione tautomer in the solid state. The C atom attached t...

Background: The growing spread of drug resistance in Helicobacter pylori has caused concern. Urease is one the most important enzymes associated with H. activity. Oxadiazoles have a wide range inhibitory activities. aim this study was to investigate new oxadiazole compounds as urease inhibitors pylori. Methods: synthesized were reused ligands previous study, and initial structure optimized by M...

In recent years there is a tremendous increase of inflammatory cases, leading to the design and development of newer anti-inflammatory agents. The reaction of 2-substituted phenyl-3-chloroacetamido quinazolin-4(3H)-ones with various 5-phenyl-1,3,4-oxadiazole-2-thiol and 5-(pyridine-4-yl)-1,3,4-oxadiazole-2thiol gave N-(4-Oxo-2-substituted phenylquinazolin-3(4H)-yl)-2-[(5-aryl-1,3,4-oxadiazol-2-...

IN THE TITLE COMPOUND [SYSTEMATIC NAME: 4-(2,3-dibromo-3-phenyl-propano-yl)-3-phenyl-1,2,3-oxadiazol-3-ylium-5-olate], C(17)H(12)Br(2)N(2)O(3), the oxadiazole ring is essentially planar, with a maximum deviation of 0.001 (3) Å. The central oxadiazole ring makes dihedral angles of 73.3 (2) and 29.0 (2)° with the adjacent and remote phenyl rings, respectively. In the crystal, adjacent mol-ecules ...

This review provides readers with an overview of the main synthetic methodologies for 1,3,4-oxadiazole derivatives, and of their broad spectrum of pharmacological activities as reported over the past twelve years.
