An Approach to Computer Aided Drug Design of some Bioactive Cinnamoyl Hydrazones, In Silico and Docking Studies as Possible COX-2 Selective Inhibitors

Recently structural analogue-based drug discovery has become an important tool for designing more potent drugs. This study uses SAR, pharmacophore study and structural analogue-based novel drugs to design selective inhibitor molecules using internet-based tools. Substituted acyl hydrazones are known for wide variety of biological activities, such as analgesic, anti–inflammatory, anti-microbial, anti-convulsant, anti-platelet, anti-tubercular, antiviral, schistomiasis and anti-tumoral activities. In the last decade several cinnamic acid derivatives were reported as potent lipoxygenase inhibitors, antioxidants and anti-inflammatory agents. We found it interesting to combine these particular molecules and design cinnamoyl hydrazones, a series of N-[(1E)-2-substituted phenyl-1-{N'-[(1E)-phenyl methylidene] hydrazine carbonyl} eth-1-en-1-yl] benzamides. The designed compounds were predicted for their drug likeness and oral bioavailability. Selected compounds were docked with COX-2 enzyme and found that they were showing similar interactions as that of SC-558, 1000 time selective standard COX-2 inhibitor.
