“…Docking energies showed that compounds 4a-d, 6a, d, and 8a-c might be good candidates for COX-2 inhibition. The docking positions of the docked compounds were similar to that of the internal ligand and the amino acids contributed in hydrogen-bond formations include Arg120, Arg513, His90, Tyr 355, Tyr385, Ser530, Ser 353, Gln192, Phe518, and Met522, which were reported in the literature (Akaho et al, 1999). The docking position of compound 4a (Fig.…”
