synthesis and biological evaluation of some newer 1h-benzo[b][1,5]diazepin-2(3h)-one derivatives as potential anticonvulsant agents

Background: regardless of the availability of all novel and earlier treatments, seizure control is notoriously complicated. in the hopes of discovering the latest and ultimate therapy, medicinal chemists will keep on to hunt for new antiepileptic compounds with high specificity and low cns toxicity. the biological effects of benzodiazepine compounds have been examined. benzene and a diazepine ring are fused together to form the chemical structure. diverse combinations of moieties attached to the innermost structure in positions 1, 2, 5, and 7 the pharmacological qualities, effect potency, and pharmacokinetic conditions are all influenced by the various side groups. methods: this paper describes the synthesis of several 1h-benzo[b][1,5]diazepin-2(3h)- one derivatives. the substituents at n1 are benzoyl, 5-substituted-1,3,4-thiadiazoles-2- yl-aminoacetyl. condensation of orthophenylene diamine with ethyl acetoacetate gave 7-substituted-4-methyl-1h-benzo[b][1,5]diazepin-2(3h)-ones, which were then linked to benzoyl chloride and chloroacetyl chloride to yield n1-benzoyl and n1-chloroacetyl derivatives. n1-chloroacetyl derivatives were further linked with 5-substituted-1,3,4-thiadiazoles amines using microwave irradiation. results: ftir, 1h-nmr, and mass spectroscopy were used to authenticate the synthesized compounds. the ptz produced convulsions method was used to test the compounds for anticonvulsant activity. when compared to the control group; compounds 4a and 4c gave 80% protection at 0.4 mg/kg, whereas compounds 2a and 2c offered 80% protection at 20 and 30 mg/ kg, respectively. conclusion: when compared to a control, the experimental synthesis and pharmacological assessment of the 1,5-benzodiazepin-2-one moiety replaced with 1,3,4-thiadiazole yields a potentially active anticonvulsant drug.
