Synthesis, Spectral Characterization and Anticonvulsant Studies of the Novel Triazolothiadiazoles Bearing Benzoxazole Moiety.

In this study, new fused triazolo-thiadiazoles (4^a-o) were synthesized via methyl 2-[bromo(phenyl)methyl]-1,3-benzoxazole-5-carboxylate. The structure of novel derivatives was recognized on the basis of spectral data results and screened their anticonvulsant action by means of maximal electroshock seizure (MES) and subcutaneous pentylenetetrazol (scPTZ) procedures. Minimal motor studies were completed by a rotarod method. Compounds 4e, 4g, 4j, 4l, 4m and 4n showing better anticonvulsant action corresponding to hydrophobicity. Other molecules remained fewer lipophilic and have less effectiveness. Most of the compounds positively tolerable the rotarod test deprived of motor deficiency. In conclusion, the prepared derivatives with distal aryl moiety exhibited higher lipophilic character and lead to improved pharmacological achievement, which can be a forthcoming promise.
