Abstract
This study describes the synthesis and characterization of some 1-(2,7-dichloro-9-[(1,3-diphenyl-1H-pyrazol-4-yl)methylene]-9H-fluoren-4-yl)-2-(methylselenyl)-ethanols and their biological evaluation as antimicrobial agents. The synthesis of the target compounds requires two key starting materials, 1-[2,7-dichloro-9H-fluoren-4-yl]-2-(methylselanyl)ethan-1-ol and various 1,3-diarylpyrazole-4-carboxaldehydes. The key intermediates, 1,3-diarylpyrazole-4-carboxaldehydes were prepared by the Vilsmeier-Haack reaction. Finally, the target compounds were obtained by a simple Knoevenagel condensation. The structures of the newly synthesized compounds were established based on spectral techniques. The synthesized compounds were screened for their in vitro antibacterial, antifungal, and anti-inflammatory activities. All the compounds were tested for their preliminary cytotoxicity by hemolysis assay. The microbial growth inhibition was also investigated via in silico molecular docking studies.
