Synthesis of 5-{[(1Hbenzo[d]imidazol-2-yl)sulfonyl]methyl}-3-phenyl-4,5-dihydroisoxazole derivatives,invitro antibacterial and antioxidant studies along with their insilico analyses

Synthesis of a series of novel sulfone derivatives 6(a-u) possessing benzimidazoles and isoxazoline rings tailored in a single molecule 5(a-u) was done by reactions using 5-(bromomethyl)-3-phenyl-4,5-dihydroisoxazoles 3(a-u) and 5-{[(1H-benzo[d]imidazol-2-yl)thio]methyl}-3-phenyl-4,5-dihydroisoxazoles 4(a-u) molecules. The chemical structures of all the newly synthesized compounds were established by IR, ¹HNMR, ¹³CNMR and LCMS spectral data. The biological characteristics of the novel sulfone compounds, such as their antioxidant and antibacterial activity, were evaluated. Among the synthesized sulfones derivatives, compounds 6 g, 6b, and 6e demonstrated outstanding antibacterial activity while compounds 6b, 6c, 6i, 6j, and 6 k demonstrated higher antioxidant activity. Further insilico absorption, distribution, metabolism, excretion, and toxicity (ADMET) studies of synthesized sulfones were studied which exhibited excellent intestinal absorption which is more than 80 %, and relatively moderate toxicity. Molecular docking studies confirmed the antibacterial and antioxidant potential which is comparable with the standard.
