A new class of azolyl indolyl thiazolidinones and azetidinones were prepared from azolyl indolyl Schiff's bases on reaction with thioglycolic acid and chloroacetyl chloride, respectively under ultrasonication at a frequency of 46 KHz. The chloro substituted thiazolyl indolyl azetidinone (12c) and imidazolyl indolyl azetidinone (13c) are prominent antibacterial agents against B. subtilis whereas 13c is the prominent antifungal agent against A. niger.
Azole derivatives are valuable precursors in pharmacological arena. In fact oxazole, thiazole and imidazole containing scaffolds display a variety of biological activities such as antitumor, antibacterial, antiviral, antioxidant, anti-inflammatory and antifungal. Azoles are also prominant molecules in various biochemical and synthetic transformations. Based on the importance of these heteroaromatics and also our interest to link the heterocycle molecules with a variety of functional groups we have synthesized a new class of bis(azolyl)sulfonamido-acetamides from azolylsulfonylamines and azolylchloroacetamides in the presence of DMAP under ultrasonication and studied their antimicrobial activity. The results will be presented.
A variety of thiophenylazolyl pyrrolylsulfamoyl acetamides were prepared by the reaction of azolylsulfamoyl acetate with pyrrolylamine in the presence of sodium methoxide in methanol under ultrasonication. Chloro, nitro and dinitro substituted thiophenylthiazolyl pyrrolylsulfamoyl acetamides (9d, 9e, 9f) and dinitro substituted thiophenylimidazolyl pyrrolylsulfamoyl acetamide (10f) exhibited potential antibacterial activity against B. subtilis. The compound 9f also displayed prominent antibacterial activity against S. aureus. The compounds 9f, chloro and nitro substituted thiophenylimidazolyl pyrrolylsulfamoyl acetamide (10d, 10e) and 10f exhibited prominent antifungal activity against A.niger.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
