Overexpression of cyclooxygenase-2 (COX-2) and prostaglandins (PG) is linked to a wide variety of human cancers. Here, we assessed whether the chemotherapeutic effect of grape seed proanthocyanidins (GSP) on non-small cell lung cancer (NSCLC) cells is mediated through the inhibition of COX-2 and PGE(2)/PGE(2) receptor expression. The effects of GSPs on human NSCLC cell lines in terms of prolife...

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...

Marine saponins are naturally glycosides compounds which possess important biomedical properties such as anti-cancer, antioxidant and anti-inflammatory. Nevertheless, no systematic studies on the anti-inflammatory potential of brittle star saponin and its underlying mechanisms have been reported. In this study, Ophiocoma erinaceus extracted saponin was investigated for its in vitro anti-inflamm...

سیکلواکسیژناز یک آنزیم کلیدی برای تولید پروستاگلاندین ها می باشد، که دارای سه ایزوفرم مختلف cox-1 cox-2, و cox-3 می باشد. گزارش شده است که میزان cox-2 در سرطان های مختلف افزایش پیدا می کند. مهارگرهای cox-2 موجب القای آپوپتوز و مهار رشد سلول های سرطانی می شوند. بنابراین cox-2 ممکن است یک هدف مولکولی برای درمان سرطان باشد. برای این منظور ابتدا سلول های k562 کشت داده شد؛ سپس غلظت های مختلف از دارو...

There is increasing evidence that L-ascorbic acid (LAA) is selectively toxic to some types of cancer cells at pharmacological concentrations, functioning as a pro-oxidant rather than as an anti-oxidant. However, the molecular mechanisms by which LAA initiates cellular signaling leading to cell death are still unclear. In an effort to gain insight into these mechanisms, the effects of LAA on euk...

Nonsteroidal anti-inflammatory drugs such as sulindac have shown promising antineoplastic activity, although toxicity from cyclooxygenase (COX) inhibition and the suppression of prostaglandin synthesis limits their use for chemoprevention. Previous studies have concluded that the mechanism responsible for their antineoplastic activity may be COX independent. To selectively design out the COX in...
