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].
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]
MitoTam (intraperitoneal injection; 2 μg/g; once a week; 4 weeks) decreases β-gal staining of lungs from MitoTam-treated mice, accompaning by a inhibition in the expression of senescence markers p16Ink4a, p21waf1 and PAI comparing control mice sup>[2].
MitoTam (intraperitoneal injection; 0.54 μmol/mouse; twice a week; 2 weeks) inhibits growth of syngeneic tumors by 80%[1].
MitoTam (intraperitoneal injection; 0.25 μmol/mouse; twice a week; 2 weeks) slows down the growth of MCF7 mock tumors and stops tumor progression after two doses; suppresses Her2high carcinomas decreased threefold from the original size with complete disappearance[1].
