synthesis, characterization and anti-inflammatory activity of some 1, 3,4 -oxadiazole derivatives
Authors
abstract
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 by column chromatography. all synthesized derivatives were determined by the carrageenan-induced rat-paw-oedema model for anti-inflammatory activity. the entire compound gives good response for the anti-inflammatory activity: [3-chloro-n-[5-(3-chloro-phenyl)-[1,3,4] oxadiazole-2yl] benzamide (c4), and [4-nitro-n-[5-(4-nitro-phenyl)-[1,3,4] oxadiazole-2yl] benzamide (c7). for this activity, indometacin was used as a standard drug and compared to new synthesized drugs. some new synthesized drugs have shown better activities for the anti-inflammation.

A series of 5-(3'-oxo-6'-(substituted aryl)-2',3',4',5'-tetrahydropyridazin-2'-ylmethyl )-2-substituted 1,3,4-oxadiazole has been synthesized. Appropriate aromatic hydrocarbon reacts with succinic anhydride in the presence of AICl3 to yield beta-aroyl propionic acid (1a). The corresponding acid is cyclized with hydrazine hydrate to give 6-(substituted aryl)-2,3,4,5-tetrahydro-3-pyridazinone (1b...
