Evaluation of Antibacterial and Antifungal Activity of some 1, 3, 4 Oxadiazoles
In the last three decades investigations in the field of oxadiazoles have been intensified due to their diverse therapeutic uses. Oxadiazole are well known to have a wide range of therapeutic activities namely anti-inflammatory, analgesic, antipyretic, anticonvulsant, antiparasitic, antimicrobial etc. In this study, we have evaluated the antimicrobial activity of some carboxymethyl derivativ...
متن کاملSynthesis of N, N΄3, 4-Dialkylamino-1, 2, 5-Oxadiazoles
N, N΄-3, 4-di(methylamino)-1, 2, 5-oxadiazole (1f) was prepared by dehydration of N, N΄-3, 4-di(methylamino)glyoxime (2f) in aqueous potassium hydroxid at 170-180 ˚C. Under similar conditions N, N΄-3, 4-di(benzylamino)-1, 2, 5-oxadiazole (1c) and N, N΄-3, 4-di(isopropylamino)...
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 کاملSELENIUM HETEROCYCLES XXXX [I] SYNTHESES OF 4- (2-PYRAZINYL) - 1, 2, 3: SELENADIAZOLE AND 4- (2-PYRAZILYL)' - l,2,3- THIADIAZOLE
Reaction of thionyl chloride with 2-acetyl-1- benzenesulfonylpyrrole semicarbazone (6 c) gave 4 - (1- benzenesulfonyl-2 - pyrrolyl) - 1, 2, 3 -thiadiazole (lc). Selenium dioxide oxidation of 2-acetylpyrazine semicarbazone (10) in acetic acid afforded 4- (2-pyrazinyl) - 1, 2, 3- selenadiazole (4). Reaction of thionyl chloride with compound 10 gave 4- (2-pyrazinyl) - 1, 2, 3- thiadiazole (3)....
متن کامل4-Hydrazino-1-methylpyrazolo[3,4-d]pyrimidine
The title compound, C(6)H(8)N(6), crystallizes as an N-H⋯N hydrogen-bond-linked dimer of two almost identical mol-ecules in the asymmetric unit. Both of the mol-ecules are almost planar (rms deviations of 0.0186 and 0.0296 Å in the two molecules) and their hydrazino groups are turned towards the pyrazole rings. The dimers are arranged into chains via inter-molecular N-H⋯N hydrogen bonds between...
