Ibuprofen phenylalanine derivatives 1-17 as new safe nonsteroidal anti-inflammatory drugs (NSAIDs) agents were synthesized and characterized depending on spectroscopic and analytical analyses. Starting from reaction between ibuprofen with PABA to have fussed derivative 1 that reacted with phenylalanine followed by hydrazine, ammonium thiocyanate, urea derivatives to afford the new compounds. For investigated drugs 1-17, molecular docking was done at the cyclooxygenase-2 (COX-2) active site. For the purpose of discussing binding affinity, the position with the lowest root-mean square deviation (RMSD) has been chosen. The binding interaction was enhanced by adding a hydrazide fragment to the parent molecule, as shown in the docking technique. Compounds 5, 6, 12, 16 and 17 were investigated as anti-inflammatory and analgesic drugs. Using a carrageenaninduced mice of hind paw edoema, we investigated the synthesized compounds' potential anti-inflammatory activity in contrast to their parent molecule, ibuprofen. The antinociceptive and the ulcerogenic effect of the synthesized compounds have been measure. Compounds 5 and 6 are the best drug analogues and these compounds could be promising for anti-inflammatory agents. .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
