MedKoo CAT#: 206777

CAS#: 224177-60-0 (HCl)

Description: Siramesine, also known as Lu-28-179, is a potent sigma-2 receptor agonist. Siramesine triggers cell death through destabilisation of mitochondria, but not lysosomes. Siramesine is a lysosomotropic detergent that induces cytoprotective autophagosome accumulation. Siramesine involves lysosomal leakage and oxidative stress.
