Biochem/physiol Actions

Siramesine is a blood-brain barrier penetrant, selective and potent sigma-2 receptor agonist, which exhibits potent and very long-lasting anxiolytic effects in rodents. Also, siramesine is a lysosome-destabilizing agent that causes lysosomal cell death in varies immortalized and cancer cell lines.
Siramesine or Lu 28-179 (1′-[4-[1-(4-fluorophenyl)-1H-indol-3-yl]-1-butyl]-spiro[isobenzofuran-1(3H),4′-piperidine]) is considered as a drug for depression and anxiety. This lysosomotropic agent stimulates mitochondrial membrane potential (MMP) reduction and the production of ROS (reactive oxygen species).
