Newly synthesized compounds were fully characterized by FT-IR, 1 H and 13 C NMR, and mass spectrometry. The pharma-cokinetic properties were screened and followed by molecular docking on COX-2 to check the in silico potency. Cytotoxicity of 5a-j molecules was evaluated against the Min-6 pancreatic cancer cell line. The 5a-j molecules have been found to have a good drugable profile and good binding affinity with the COX -2 enzyme. In addition, the in vitro cytotoxic potential of the synthesized compounds showed promising inhibition potential against cancer cell lines. The most promising compounds, 5e (IC50 11.33) and 5g (IC50 17.30) show the most remarkable cytotoxic activity as compared to other analogues. The results convey that the designed molecules are promising products for level-up biological evaluation.(c) 2022 Elsevier B.V. All rights reserved. 收起
