6-Carbethoxy-5-(3'-bromophenyl)-3-aryl-2-cyclohexenones 2a-j were obtained from the1-Aryl-3-(3'-bromophenyl)-2-propene-1-ones 1a-j by Micheal addition of ethyl acetoacetate, followed by internal Claisen condensation. Reaction of 2a-j with hydrazine hydrate afforded the corresponding 6-Aryl-4-(3'-bromophenyl)-3-oxo-2,3a,4,5-tetrahydro-2H-indazoles 3a-j. The structures of newly synthesized compou...
An efficient and convenient protocol for synthesis of 3-hydroxy-3-indolyl-2-oxindoles and 3,3-diindolyl-2-oxindoles is presented here. The syntheses were achieved selectively under catalysis of LiClO4 whereby the products were obtained purely.
Background & Aim: Post-operative pain is a frequent complication after surgery which can increase the risk of other post-operation complications and also the duration of hospital stay. In this study, we have tried to assess the effect of rectal diclofenac as pre-emptive analgesia to reduce post-operative pain after ophthalmic surgeries(vitrectomy).Patients and Method: This study was design...
Aims and background: This study aimed to compare Rabeprazole with ranitidine on decreasing epigastric pain in patients undergoing vitrectomy surgery in Rasoul-e-Akram hospital during 1391-1392. Materials and methods: This study was a double-blinded randomized controlled trial on patients undergoing vitrectomy. Patients were divided into three groups receiving: Rabeprazole (20 mg), Ranitidine ...
