Synthesis and Pharmacological Activities of Some New 5-Substituted-2-mercapto-1,3,4-oxadiazoles
In this study, various 5-β-[(N-benzenesulphony/tosyl)-4-(un) substituted anilino]ethyl-2-mercapto-1,3,4-oxadiazole (4a-f), with sulphonamide moiety at the side chain have been synthesised. The structures of the newly synthesised compounds have been established on the basis of their spectral data and elemental analysis. All the compounds were screened for antimicrobial activities against Escheri...

متن کاملSynthesis and QSAR studies of thiosemicarbazides, 1,2,4-triazoles, 1,3,4- thiadiazoles and 1,3,4-oxadiazoles derivatives as potential antibacterial agents
Several new 2-(2-(4-chlorophenyl)acetyl)-N-arylhydrazinecarbothioamides 1, 5-(4-chlorobenzyl)-4-aryl-4H-1,2,4triazole-3-thiols 2, 5-(4-chlorobenzyl)-N-aryl-1,3,4-thiadiazol-2-amines 3 and 5-(4-chlorobenzyl)-N-aryl-1,3,4-oxadiazol-2amines 4 have been synthesized and screened for their antibacterial activity against gram +ve and gram –ve bacteria i.e S.aureus and E. coli. The QSAR studies of thes...
متن کاملSynthesis, In vitro Antimicrobial and Cytotoxic Activities of Some Novel Bis- 1, 3, 4-oxadiazoles
A series of novel bis-1,3,4-oxadizaoles were synthesized by oxidative cyclisation of respective Schiff bases derived from dicarbohydrazide using ceric ammonium nitrate (CAN) as catalyst. The synthesized compounds were screened for in vitro antibacterial activity against Staphylococcus aureus (MTCC 87), Escherichia coli (MTCC 46) and antifungal activity against Candida albicans (NCIM 3471) by tw...
متن کاملSynthesis of some new 2-(3-methyl-7-substituted-2-oxoquinoxalinyl)-5-(aryl)- 1,3,4-oxadiazoles as potential non-steroidal anti-inflammatory and analgesic agents
Ethyl (3-methyl-7-substituted-2-oxoquinoxalin-1(2H)-yl) acetates 2a-c are prepared by the condensation of ethyl chloroacetate with 3-methyl-7-substituted quinoxalin-2(1H)-ones 1a-c. The reaction of 2a-c with hydrazine hydrate furnished 2-(3-methyl-7-substituted-2-oxoquinoxalin-1(2H)-yl) acetohydrazides 3a-c, which on cyclisation with substituted aromatic carboxylic acids in the presence of phos...
