Synthesis of new 2,5-Disubstituted-1,3,4-thiadiazoles and preliminary evaluation of anticonvulsant and antimicrobial activities
摘要:
Two new series of 2.5-disubstituted-1,3.4-thiadiazoles were synthesized for their possible anticonvulsant. antibacterial and antifungal activities. The degree of protection afforded by these compounds at a dose of 100 mg/kg ip against pentylene-tetrazole-induced convulsions in mice ranged from 0 to 90%, Among these compounds, 2a (90%) and 2g (70%) showed maximum protection. Antimicrobial tests showed that the MIC value of 3j against Pseudomanas aeruginosa was equal to that of penicillin. (C) 2002 Elsevier Science Ltd. All rights reserved.
Synthesis and preliminary anticancer activity of new 1,4-dihydro-3-(3-hydroxy-2-naphthyl)-4-substituted-5H-1,2,4-triazoline-5-thiones
摘要:
1,4-Dihydro-3-(3-hydroxy-2-naphthyl)-4-substituted-5H-L2,4-triazolinc-5-thiones were synthesized. The structures of original eight compounds were confirmed by elemental analysis,H-1 NMR and mass spectral methods. One of the compounds (3a) was tested in vitro for its anticancer activity against 52 human tumor cell lines. (C) 2002 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
