Human polymorphonuclear neutrophils (PMN) were treated with the antiinflammatory agents dexamethasone or Auranofin. PMN treated with dexamethasone in a dose range of 0.25-1 microM or Auranofin, 5-15 mM, were stimulated with 10(-7)M N-formyl-methionyl-leucyl-phenylalanine (FMLP). These agents were shown to inhibit the functional responses of degranulation and superoxide production in a dose-depe...

Epidemlological and laboratory studies indicate an inverse relationship between the risk of colon cancer development and intake of nonsteroldal antiinflammatory agents, including aspirin. One of the mechanisms by which nonsteroidal antiinflammatory agents Inhibit colon carcInogenesis Is through the inhibition of prostaglandIn production by cyclooxygenase isozymes (COX-1 and COX-2). Overexpressi...

Cardiac surgery is associated with the development of a systemic inflammatory response. The cytokine response in cardiac surgery patients is well explained and is dominated by the pro-inflammatory cytokines tumour necrosis factor (TNF-α), interleukin-6 (IL-6), interleukin-8 (IL-8), and the antiinflammatory cytokine interleukin-10 (IL-10). The release of these cytokines has been related to the d...

Salicylates are widely used in the treatment of rheumatic disorders, and they have been shown to induce minor changes in renal function. One of the major mechanisms of action of salicylates is the suppression of prostaglandin synthetase activity, and in animal rnodels renal prostaglandin production is closely related to renin release and the regulation of renal blood flow. Indomethacin has been...

Historically, natural products (NP’s) have played a significant role in drug discovery, not only cancer and infectious diseases, but also other therapeutic areas including cardiovascular diseases multiple sclerosis. Profit loss, Partnerships averages, present certain challenges for such as technical obstacles to screening, isolation, characterization optimization, which added decline their sear...
