Abstract
New series of 2,4-diaryl-3-azabicyclo[3.3.1]nonan-9-one 4′-phenylthiosemicarbazones (compounds 9–16) was obtained from the corresponding 2,4-diaryl-3-azabicyclo[3.3.1]nonan-9-ones. The synthesized compounds have been characterized by their elemental, analytical, and spectral studies. Besides, these reported compounds were screened for their antibacterial and antifungal activities against a spectrum of microbial organisms. These studies proved that against bacteria, compounds 10 and 11 against Bacillus subtilis, compound 13 against Salmonella typhi, show maximum inhibition potency at low concentration (6.25 μg/mL), whereas against fungal, compounds 11, 13, and 16 against Candida albicans and compounds 12 and 13 against Cryptococcus neoformans, showed beneficial antifungal activity at minimum concentration (6.25 μg/mL).
