Model 37481 - SP-8356

SP-8356 is a derivative of (1S)-(–)-verbenone and an inhibitor of CD147, also known as extracellular matrix metalloproteinase (MMP) inducer (EMMPRIN) and previously known as tumor cell-derived collagenase stimulatory factor (TCSF).1,2 It inhibits the dimerization of CD147 and the protein-protein interaction between CD147 and its ligand cyclophilin A. SP-8356 (10 µM) decreases recombinant human CD147-induced migration of A-10 vascular smooth muscle cells (VSMCs) and reduces cyclophilin A-induced increases in MMP-9 activity in, and adhesion of, isolated rat monocyte-derived macrophages. It also prevents glucose-oxygen deprivation-induced increases in reactive oxygen species (ROS) and lactate dehydrogenase (LDH) release in primary rat cortical neurons in an in vitro model of ischemia when used at a concentration of 10 µM.3 SP-8356 (5 µM) inhibits the migration and invasion of MDA-MB-231 breast cancer cells.
