Usefulness of selective COX-2 inhibitors as therapeutic agents against canine mammary tumors.
Cyclooxygenase-2 (COX-2) is a key enzyme for converting arachidonic acids to prostanoids, which are known to be induced during inflammation and cancer initiation. Previously, it has been reported that COX inhibitors, such as aspirin, reduce the incidence of human colorectal cancer; therefore, it is widely believed that COX-2 is a potential therapeutic and chemoprevention target for several type...
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 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 کاملCox-2 levels in canine mammary tumors, including inflammatory mammary carcinoma: clinicopathological features and prognostic significance.
Cyclo-oxygenase (Cox-2) plays an important role in mammary carcinogenesis, nevertheless, its role in canine mammary tumors, and particularly in inflammatory mammary carcinoma (IMC), is unknown. Tumor Cox-2 levels were analyzed by enzyme immunoassay, in post-surgical tumor homogenates of 129 mammary tumors (62 dysplasias and benign tumors, 57 malignant non-IMC and 10 IMC) from 57 female dogs. Th...
