Design, Synthesis, and Evaluation of New Tripeptides as COX-2 Inhibitors
Cyclooxygenase (COX) is a key enzyme in the biosynthetic pathway leading to the formation of prostaglandins, which are mediators of inflammation. It exists mainly in two isoforms COX-1 and COX-2. The conventional nonsteroidal anti-inflammatory drugs (NSAIDs) have gastrointestinal side effects because they inhibit both isoforms. Recent data demonstrate that the overexpression of these enzymes, a...
متن کاملDesign and Synthesis of New Biarylhydrazides Possessing an Azido Pharmacophore as Selective COX-2 Inhibitors
A group of 1,3-biarylhydrazide derivatives possessing a COX-2 azido pharmacophore at the Para- position of the C-1 phenyl ring in conjunction with a N-3 phenyl or substituted-phenyl ring (4-F,4-Cl,4-OMe) were designed and synthesized based on nucleophilic substitution reaction. A molecular modelling study of these compounds showed that the designed molecules were well bound with the active site...
متن کاملDesign, Synthesis and Biological Evaluation of Novel Peptide-Like Analogues as Selective COX-2 Inhibitors
A new series of peptide-like derivatives containing different aromatic amino acids andpossessing pharmacophores of COX-2 inhibitors as SO2Me or N3 attached to the para positionof an end phenyl ring was synthesized for evaluation as selective cyclooxygenase-2 (COX-2)inhibitors. The synthetic reactions were based on the solid phase peptide synthesis methodusing Wang resin. One of the analogues, i...

متن کاملDesign, Synthesis and Biological Evaluation of New Imidazo[2,1-b]Thiazole Derivatives as Selective COX-2 Inhibitors
A new series of imidazo[2,1-b]thiazole analogs containing a methyl sulfonyl COX-2 pharmacophore was synthesized and evaluated for their COX-2 inhibitory activity. According to in-vitro COX-1/COX-2 inhibition data, all compounds (6a-g) were selective inhibitors of COX-2 isoenzyme with IC50 values in the highly potent 0.08-0.16 mM range. These results indicated that both potency and selectivity o...
