Synthesis of 4- and 5- nitro-substituted heteroaryl cinnamoyl derivatives
In the condensation of the 4and 5-nitro-substituted 2-acetyl-1,3-indandione with heteroaryl aldehydes in the presence of alkaline or acidic catalysts, the corresponding cinnamoyl derivatives are obtained that possess anticoagulant activity, compared with that of 2-acetyl-1,3-indandione. It has been proven that some of the sodium salts of the cinnamoyl-indandione possess anticoagulant activity. ...
متن کاملSynthesis, Characterization and Study of Some N-Substituted Aryl-2- ({4-[(Substituted Aryl Carbamoyl) Methyl]-5-(Pyridin-4-yl)-4H-1, 2, 4-Triazol-3-yl} Sulfanyl) Acetamide
Pathogenic infections and inflammation are very common ailments humans suffer. Upsurge of resistant pathogens has impeded the antimicrobial drug development process in recent years and the search of new antimicrobial agents is clearly evident from the literature. In line with these developments the synthesis of N-substituted aryl-2-({4-[(substituted aryl carbamoyl) methyl]-5-(pyridin-4-yl)-4H-1...
متن کاملSynthesis and Antibacterial Evaluation of (S,Z)-4-methyl-2-(4-oxo-5- ((5-substituted phenylfuran-2-yl) methylene)-2-thioxothiazolidin-3-yl) Pentanoic Acids
The resistance of antimicrobials has become a global hazard with the irrational use of antibiotics. Infection of drug-resistance bacteria seriously threatens human health. Currently there is an urgent need for the development of novel antimicrobial agents with new mechanisms and lower levels of toxicity. In this paper, a series of (S,Z)-4-methyl-2-(4-oxo-5-((5-substitutedphenylfuran-2-yl) methy...

متن کاملGreen synthesis and evaluation of 5-(4-aminophenyl)-4-aryl-4H-1, 2, 4-triazole-3-thiol derivatives
The green synthesis of 5-(4-aminophenyl)-4-aryl-4H-1,2,4-triazole-3-thiol was achieved in four steps, In first step, 4-amino benzoic acid refluxed in ethanol along with catalyst Conc. Sulphuric acid to produce ethyl-4-amino benzoate I. Further compound I refluxed with hydrazine hydrate in ethanol to produce 4-amino benzohydrazide II. Compound II refluxed in ethanolic potassium hydroxide with ca...
