A series of substitututed methylene/ethylene 4-fluorophenylhydrazide derivatives (3a–p) was synthesized with the aim of evaluating their antimycobacterial activity toward a strain of Mycobacterium tuberculosis H37Rv. Their chemical structures were confirmed by 1H-nuclear magnetic resonance (NMR) and electrospray mass spectrometry (ES-MS) spectral data, and(More)
Various 3-acetyl-2,5-disubstituted-2,3-dihydro-1,3,4-oxadiazoles (11–20) were prepared by the reaction of aryl substituted hydrazones of 4-fluorobenzoic acid hydrazide (1–10) with acetic anhydride. The structures of the synthesized compounds 11–20, were confirmed by UV, IR, 1H-NMR and mass spectroscopic methods. Antifungal evaluation of the(More)
Hydrazones and the piperidine ring containing compounds were considered as beneficial substrates in drug design. Therefore, this study was aimed at the synthesis of new benzoyl hydrazones derived from ethyl 4-oxopiperidine-1-carboxylate and 2,6-diphenylpiperidin-4-one. The synthesized compounds (1-19) were screened for their antioxidant, anticholinesterase(More)
Synthesis of chalcones and 2-pyrazoline derivatives has been an active field of research due to the established pharmacological effects of these compounds. In this study, a series of chalcone (1a–i), 2-pyrazoline-1-carbothioamides (2a–i), and 2-pyrazoline-1-carboxamide derivatives (3a–g) were synthesized and screened for their potential pesticide(More)
