Opitor-0 is a potent and selective inhibitor of the mitochondrial GTPase Optic atrophy protein 1 (OPA1) with an IC50 of approximately 3 µM. In cellular studies, Opitor-0 disrupts OPA1 oligomer stability, leading to mitochondrial fragmentation and remodeling of mitochondrial cristae. These structural changes facilitate the release of Cytochrome c from mitochondria into the cytosol, triggering apoptotic signaling. The compound exhibits significant pro-apoptotic and antitumor effects in cancer cell models. Importantly, Opitor-0 demonstrates strong synergistic activity with Bcl-2 inhibitors such as ABT-737 and Venetoclax, enhancing tumor cell death. These results suggest that Opitor-0 effectively targets mitochondrial dynamics and apoptosis pathways in cancer cells.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
