Cyclooxygenase-1-Selective Inhibitors Based on the (E)-2′-Des-methyl-sulindac Sulfide Scaffold
摘要:
Prostaglandins (PGs) are powerful lipid mediators in many physiological and pathophysiological responses. They are produced by oxidation of arachidonic acid (AA) by cyclo- oxygenases (COX-1 and COX-2) followed by metabolism of endoperoidde intermediates by terminal PG synthases. PG biosynthesis is inhibited by nonsteroidal anti-inflammatory drugs (NSAIDs). Specific inhibition of COX-2 has been extensively investigated, but relatively few COX-1-selective inhibitors have been described. Recent reports of a possible contribution of COX-1 in analgesia, neuroinflammation, or carcinogenesis suggest that COX-1 is a potential therapeutic target. We designed, synthesized, and evaluated a series of (E)-2'-des-methyl-sulindac sulfide (E-DMSS) analogues for inhibition of COX-1. Several potent and selective inhibitors were discovered, and the most promising compounds were active against COX-1 in intact ovarian carcinoma cells (OVCAR-3). The compounds inhibited tumor cell proliferation but only at concentrations >100-fold higher than the concentrations that inhibit COX-1 activity. E-DMSS analogues may be useful probes of COX-1 biology in vivo and promising leads for COX-1-targeted therapeutic agents.

The presently disclosed subject matter provides derivatives of non-steroidal anti-inflammatory drugs (NSAIDs) that are characterized by substantially reduced cyclooxygenase inhibiting activity, yet retain the ability to interact with and modulate the activities of other polypeptides such as the class of peroxisome proliferators-activated receptors (PPARs) and γ-secretase. Also provided are methods of using the derivatives to treat pathological disorders.
