mitochondrial cristae structure

Opitor-0 is a OPA1 GTPase inhibitor with an IC₅₀ of 3.0 μM. Opitor-0 disrupts mitochondrial cristae structure and respiratory efficiency, induces mitochondrial fragmentation, enhances cBID-mediated cytochrome c release, and restores the sensitivity of triple-negative breast cancer (TNBC) cells to ABT-737 (HY-50907). Opitor-0 selectively reduces the migration and proliferation capacities of metastatic breast cancer cells, and induces cell death and apoptosis. Opitor-0 can be used in studies related to metastatic breast cancer and triple-negative breast cancer .

TPE-Ph-In is a mitochondria-targeted voltage-sensitive probe that can be used for mitochondrial membrane potential detection, mitochondrial imaging of animal and plant cells and tissues, mouse sperm activity indication, and detection of mitochondrial membrane potential changes associated with early apoptosis. TPE-Ph-In is non-fluorescent in solution, but emits strong fluorescence when aggregated via restriction of intramolecular rotation/movement, and its fluorescence intensity is directly correlated with local probe concentration or mitochondrial membrane potential level. TPE-Ph-In can penetrate cell membranes, target mitochondria through charge-dependent accumulation, has low cytotoxicity and high photostability, and enables super-resolution imaging of plant mitochondrial fission, fusion and cristae structures. The excitation wavelengths of TPE-Ph-In include 450 nm, 488 nm, and 489 nm, while its emission wavelengths include 551-661 nm, 660 nm, and 694 nm. TPE-Ph-In can be used for studies on mitochondrial dysfunction associated with early apoptosis .
