Description_x000D_ Application_x000D_ Human endothelial cells, HMEC-1 were treated with Sulindac sulfide and the effect on cell survival was studies by MTT assay._x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ Sulindac sulfide is a non-steroidal anti-inflammatory compound with a preference for COX-1; it is an inhibitor of Ras activation of Raf-1. It impairs nucleotide exchange on Ras by CDC25 and accelerates Ras hydrolysis of GTP by p120GAP. It is an active metabolite of sulindac. It is also shown to inhibit growth and induce apoptosis in human prostate cancer cells through a COX-1 and COX-2 independent mechanism. Sulindac sulfide is an analgesic that has antiproliferative and apoptotic effects. It inhibits the expression and activity of cyclooxygenase-2 in human colon cancer cells and reduces tumor burden in adenomatous polyposis patients._x000D_ Other Notes_x000D_ Tandem Mass Spectrometry data independently generated by Scripps Center for Metabolomics is available to view or download in PDF.
