MitoTam bromide, hydrobromide, a Tamoxifen derivative, is an electron transport chain (ETC) inhibitor. MitoTam bromide, hydrobromide reduces mitochondrial membrane potential in senescent cells and affects mitochondrial morphology. MitoTam bromide, hydrobromide is an effective anticancer agent, suppresses respiratory complexes (CI-respiration) and disrupts respiratory supercomplexes (SCs) formation in breast cancer cells.

Description

MitoTam bromide, hydrobromide, a Tamoxifen derivative[1], is an electron transport chain (ETC) inhibitor. MitoTam bromide, hydrobromide reduces mitochondrial membrane potential in senescent cells and affects mitochondrial morphology[2]. MitoTam bromide, hydrobromide is an effective anticancer agent, suppresses respiratory complexes (CI-respiration) and disrupts respiratory supercomplexes (SCs) formation in breast cancer cells[1][2].

In Vitro

MitoTam (0.5 μM-56 μM; 24 hours) kills breast cancer cell Lines and nonmalignant cells with an IC50 range from 0.65 μM to 55.9 μM[1].
MitoTam (2.5 μM; 2-24 hours) results in stronger activation of the apoptotic pathway in MCF7 Her2 high cells compared with mock MCF7 cells[1].
MitoTam (0.05 μM-1 μM; 3 days) causes a concentration-dependent induction of apoptosis in breast cancer cells, while there was no effect for non-malignant breast epithelial cells[2]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
