SYNTHESIS, CHARACTERISATION AND ANTIMICROBIAL ACTIVITY OF NEW NICOTINAMIDE-THIAZOLE DERIVATIVES

Synthesis and Screening of Some New Isatin Containing Thiazole Derivatives for Antimicrobial Activity

In the present work, a series of new N’-[{5-(4-aryl) 1,3-thiazol-2yl}carbohydrazide-methyl]- 3(4-arylimino) indol-2-one analogs (5a-g) had heen synthesized from 3-(4-arylimino)-2-oxo- 1-indole-acetylthiosemicarbazide (4a-g) in ethanol, in the presence of phenacyl bromide or substituted phenacyl bromides. The compound 5e was characterized by its elemental analysis, IR, 1 HNMR and Mass Spectrosco...

Synthesis and Antimicrobial Activity of Some New Isatin Derivatives

Some new 3-[(5-benzylidene-2-phenyl)-3, 5-dihydro-4-H-imidazol-4-one-3-(4-bezoylhydrazono)]-indole-2-ones (VIII) have been synthesized from different isatinhydrazones (II) by condensing with 2-phenyl-5-benzylidene- 3-N (4-acetyl phenyl)-1, 5-dihydro-imidazol-4-one (VII). Their chemical structures have been confirmed by IR, 1HNMR, MASS and by elemental analysis. Investigation of antimicrobial ac...

Synthesis of New Thiazole, Bithiazolidinone and Pyrano[2,3-d ]thiazole Derivatives as Potential Antimicrobial Agents

In an attempt to find a new class of antimicrobial agents, a series of thiazole derivatives containing furan moiety 3, 7, 8a,b, 10a-c and 12 were prepared via the reaction of 2-cyano-N-(furan-2-ylmethyl)acetamide (1) with phenyl isothiocyanate and α-halocarbonyl compounds. Also, many bithiazolidinone and pyranothiazole derivatives were synthesized through interaction of thiazolidinone 7 with ap...
