Evaluation of cytotoxicity mechanism of two cyclo-oxygenase-2 inhibitors in leukemia cell line
Introduction: Leukemia is considered one of the main causes of death, and current chemotherapeutic agents are unable to provide optimal responses due to chemo-resistance. Therefore, there is a constant need for new drugs. Cyclooxygenase- 2 (COX-2) inhibitors can be helpful by reducing the necessary dose of routine chemotherapeutic drugs. Herein, we evaluated the cytotoxicity activity as well...
متن کاملSpecific desensitization of the canine renal vasculature to angiotensin II despite cyclo-oxygenase inhibition.
Intrarenal angiotensin (AII) infusion results in a poorly sustained renal vasoconstrictor response. To examine the relationship between fade and renal tachyphylaxis to AII, sub-pressor doses of AII and norepinephrine (NE) were injected into the renal arteries of anesthetized dogs, resulting in a transient reduction (greater than 50 percent) in renal blood flow. Continuous intrarenal AII infusio...
متن کاملSelective cyclo-oxygenase-2 inhibitors impair adipocyte differentiation through inhibition of the clonal expansion phase.
Selective cyclo-oxygenase-2 (COX-2) inhibitors are nonsteroidal antiinflammatory drugs used in the management of inflammatory diseases. We demonstrate here that inhibition of the COX-2 enzyme impairs adipocyte differentiation. The inhibition of adipogenesis occurs in the early clonal expansion phase. In particular, COX-2 inhibition limits cell cycle reentry required before terminal adipocyte di...
متن کاملA three-step kinetic mechanism for selective inhibition of cyclo-oxygenase-2 by diarylheterocyclic inhibitors.
Cyclo-oxygenase (COX) enzymes are the targets for non-steroidal anti-inflammatory drugs (NSAIDs). These drugs demonstrate a variety of inhibitory mechanisms, which include simple competitive, as well as slow binding and irreversible inhibition. In general, most NSAIDs inhibit COX-1 and -2 by similar mechanisms. A unique class of diarylheterocyclic inhibitors has been developed that is highly se...
متن کاملEffects of cyclo-oxygenase inhibition on exhaled eicosanoids in patients with COPD.
BACKGROUND Leukotriene (LT) B4 concentrations are increased and prostaglandin (PG) E2 concentrations are decreased in exhaled breath condensate (EBC) in patients with chronic obstructive pulmonary disease (COPD). A study was undertaken to investigate the short term effects of cyclo-oxygenase (COX) inhibition on exhaled LTB4 and PGE2 concentrations in patients with COPD and to identify the COX i...
