Condensation of thiohydrazide analogues with 4-bromo-3, 6-dichloropyridazine: an efficient rout to pyridazino[4, 3-e][1, 3, 4] thiadiazines
Abstract- Some new 3-(alkylsulfanyl)- 7-chloro-1-phenyl-1H-pyridazino [4,3-e][1,3,4]thiadiazine were synthesized by treatment of the alkyl-2-phenylhydrazinecarbodithioates with 4-bromo-3,6-dichloropyridazine in alkaline acetonitril. Orientation of the reaction has been determined by X-Ray crystallography technique. The chlorine atom on the number 7 position of these products was repla...

متن کاملSynthesis and Anticonvulsant Activity Evaluation of 3-alkoxy-4-(4- (hexyloxy/heptyloxy)phenyl)-4H-1,2,4 -triazole
A series of 3-alkoxy-4-(4-(hexyloxy/heptyloxy) phenyl)-4H-1,2,4-triazole was synthesized. The anticonvulsant effect and neurotoxicity of the compounds were calculated with maximal electroshock (MES) test and rotarod tests with intraperitoneally injected mice. Among the synthesized compounds, compound 3-heptyloxy-4-(4-(hexyloxy) phenyl)-4H-1,2,4-triazole (5f) was the most active one and also had...
