Description: SR-31747A is a synthetic peripheral sigma receptor ligand with immunomodulatory and potential antitumor activities. Although the exact mechanism by which SR31747A exerts its antitumor effects has not been fully established, SR31747A binds to and inhibits the sigma1 receptor (SR31747A-binding protein-1 or SR-BP1), human sterol isomerase (emopamil-binding protein) and the sigma2 receptor, which may result in a reduction in tumor cell proliferation and tumor cell apoptosis. In addition, this agent inhibits the production of pro-inflammatory cytokines while increasing anti-inflammatory cytokines.

Additional Information

SR 31747 is a novel immunosuppressant agent that arrests cell proliferation in the yeast Saccharomyces cerevisiae, SR 31747-treated cells accumulate the same aberrant sterols as those found in a mutant impaired in delta 8- delta 7-sterol isomerase. (from MCB).
SR31747 was shown to inhibit Δ8-Δ7 sterol isomerase in yeast. SR31747 is a high affinity ligand of recombinant mammalian sterol isomerase (Kd = 1 nM). For detail, please see: Pharmacology and Experimental Therapeutics
