Abstract
Abstract A series of novel α ‐(diphenylphosphoryl)‐ and α ‐(diphenylphosphorothioyl)cycloalkanone oximes have been synthesized in search for novel bioactive molecules. Their structures were characterized by various spectroscopic methods including IR, NMR ( 1 H, 31 P, 13 C), mass spectrometry and single crystal X‐ray diffraction. The newly synthesized phosphorus‐containing oximes were screened for their in vitro antimicrobial activity against Gram‐positive bacteria ( Staphylococcus aureus and Bacillus subtilis ), Gram‐negative bacteria ( Escherichia coli and Salmonella typhimurium ) and fungal strains ( Candida albicans and Candida glabrata ). The biological assays showed that all the studied compounds exhibited high antibacterial and antifungal activities at only 0.1–2.1 μg/mL. In silico molecular docking studies in FabH enzyme active site were performed in order to predict the possible interaction modes and binding energies of the drug candidates at the molecular level.
