Abstract

In present investigation the synthesis of few 2-(substituted phenyl-3-(5-substituted phenyl-4H-1, 2, 4-triazole-3-yl)-thiazolidine-4-ones and 3-(5-(4-substituted phenyl)-1, 3, 4-thiadiazole-2-yl)-2-phenylthiazolidine-4-ones is reported with the aim of achieving enhanced anticonvulsant effect. Two schemes were designed viz. first scheme for clubbed triazole-thiazolidinone derivatives and second scheme for clubbed thiadiazole-thiazolidinone derivatives. The compounds were characterized on the basis of IR, 1H-NMR and Mass analyses. Acute toxicity study was done to determine the LD50 of the compounds. Some of the compounds were evaluated for their anticonvulsant activity using PTZ induced convulsions method. The compounds DCThizd-N and NMThizd-N showed highest percentage of protection (80%) at the dose of 30mg/kg among the evaluated compounds compared to control. Keywords: 4-Thiazolidinone, Triazole, Thiadiazole, Anticonvulsant activity.

Abstract

Several new promising bioactive derivatives of N-(5-(Substituted)-1, 3, 4-thiadiazol-2-yl)-2-((5-(substitutes)-4H-1, 2, 4-triazol-3-yl) amino) acetamide were synthesized. The compounds were obtained in excellent yields. The synthesized compounds were confirmed on the basis of IR and NMR. Acute toxicity study was done to determine the LD50 of the newly synthesized compounds. Some of the synthesized compounds were evaluated for their anticonvulsant effect by PTZ induced convulsions method. Statistical testing was done by one way ANOVA followed by Dunnett’s test. The compounds D-III showed the highest percentage of protection as compared to PTZ, i.e. 80% at the dose of 20mg/kg among the evaluated compounds compared to control. Keywords: 1, 3, 4-thiadiazole, 1, 2, 4-triazole, Anticonvulsant
