Usage And Synthesis

Description

Siramesine (Lu 28-179, 147817-50-3) is a σ2 selective agonist(IC50’s: σ1 = 17nM, σ2 = 0.2nM).1It produced non-sedating potent and long-last anxiolytic effects in rodents.2Siramesine induced caspase-independent programmed cell death in various cancer cell linesviaincreased levels of ROS and lysosomal leakage.3,4,5Mitochondrial destabilization via loss of membrane potential and increased ROS has also been offered as a mechanism of action for the triggering of cell death by Siramesine.6

Uses
