Additional Information:

Siramesine is a σ2 selective agonist with IC50’s for σ1 = 17nM and σ2 = 0.2nM (1). This compound produced non-sedating potent and long-last anxiolytic effects in rodents (2), it induced caspase-independent programmed cell death in various cancer cell lines via increased levels of ROS and lysosomal leakage (3,4,5) and mitochondrial 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).
