NCIt definition : The active metabolite of sulindac, a sulfinylindene derivative with anti-inflammatory,
analgesic and antipyretic properties. Sulindac is a nonsteroidal anti-inflammatory
drug (NSAID) which inhibits cyclooxygenase (COX-1 and-2)-mediated conversion of arachidonic
acid to pro-inflammatory prostaglandins. This agent may possess chemopreventive activity
against colorectal tumors through a mechanism that involves the induction of apoptosis.
The sulfide metabolite is excreted in the bile and reabsorbed from the intestine,
thereby helping to maintain constant blood levels and reduce gastrointestinal side
effects. (NCI04);
