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...

Synthesis, 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...

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Syntheses, Antibacterial and Antifungal Activities of Substituted-Thiazolo-1,3,4-Thiadiazoles, 1,3,4-Oxadiazoles and 1,2,4-Thiazoles

Starting from readily available 2-substituted-4-methylthiazole-5-carboxylic acid hydrazide (1), The title compounds were prepared. The reaction of compound 1 (R=CH3) with formic acid yielded 1-(formyl)-2-(2,4-dimethylthiazole-5-carboxyl) hydrazine (2). Refluxing the latter with phosphorous pentasulfide in xylene afforded compound 3, the reaction of compound 2 with phosphorous pen...
