Synthesis, antimicrobial activity and molecular docking study of novel α‐(diphenylphosphoryl)‐ and α‐(diphenylphosphorothioyl)cycloalkanone oximes

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), Gramnegative bacteria (Escherichia coli and Salmonella typhimurium) and fungal strains (Candida albicans and Candida glabrata). The biological assays showed that all the studied compounds (2a-f) 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.
