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...

متن کاملSynthesis and antihepatotoxic activity of some new chalcones containing 1, 4 - dioxane ring system.
Silybum marianum is a medicinal plant used widely for treating liver diseases. The silymarin, a mixture of three flavolignan isomers namely silybin (1), silydianin (2), and silychristin (3) is an active constituent of the plant. However, silybin containing 1, 4-dioxane ring is the most potent antihepatotoxic agent. In contrast, other isomers do not possess 1, 4-dioxane ring, and thus do not exh...

Synthesis of New β-Lactams Bearing the Biologically Important Morpholine Ring and POM Analyses of Their Antimicrobial and Antimalarial Activities
Some new b-lactams bearing biologically important morpholine ring have been synthesized by acylation of amino b-lactams in the presence of morpholine-4-carbonyl chloride. These novel β-lactams were prepared under mild reaction conditions without any solvent in short reaction times. Their biological activities have been examined against microbial agents such as Staphylococcus aureus (S. aureus),...
متن کاملSynthesis of some New Imidazolones and 1,2,4-Triazoles Bearing Benzo[b]thiophene Nucleus as Antimicrobial Agents
2-Phenyl-1-(3?,5?-dichloro-2?-benzo(b)thiophenoylamino)-4-arylidine-5-imidazolones (2a-j) were prepared from the 2-hydrazinocarbonyl-3,5-dichlorobenzo[b]thiophene 1 by the reaction with different oxazolinone which were prepared by the condensation of substituted benzaldehyde with benzoyl glycine in presence of sodium acetate and acetic anhydride. Reaction of 1 with different aromatic isothiocya...
