Synthesis and evaluation of the antifungal effects of [5-aryl-[1, 3, 4] oxadiazole-2-yl] phenyl-methanol
Introduction: Nowadays the drug resistance outbreak in fungi is considered a serious threat to the health of human societies. Oxadiazole derivatives that are high biologically applicable can be a good alternative to common anti-fungal drugs. The purpose of this study was to evaluate the anti-fungal properties of new derivatives synthesized of oxadiazole and compare them with common anti-fungal ...
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 کاملDesign, synthesis and antifibrotic activities of carbohydrate-modified 1-(substituted aryl)-5-trifluoromethyl-2(1H) pyridones.
Pirfenidone, a pyridone compound, is an effective and novel antifibrotic agent. In this article, we describe the design, synthesis and activity evaluation of novel antifibrotic agents, 1-(substituted aryl)-5-trifluoromethyl-2(1H) pyridones modified with carbohydrate. Most of the title compounds exhibited comparable or better inhibitory activity than fluorofenidone. Notably, compound 19a demonst...
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...
متن کاملDetermination of the acid dissociation constants of the p-sulphonato-calix[4]arene
The acid dissociation constants of the hydroxyl groups in 25, 26, 27, 28-tetrahydroxy-5, 11, 17, 23-tetrasulphonic-calix[4]arene (SC4) were determined at 25οC by a combination of potentiometric and spectrophotometric titration method. The first and second acid dissociation constants (pKa1, pKa2) were found to be 3.19 and 12.1, which demonstrated pKa shift due to intramolecular hydrogen bonding ...
