IMT1 is a first-in-class specific and noncompetitive human mitochondrial RNA polymerase (POLRMT) inhibitor. IMT1 causes a conformational change of POLRMT, which blocks substrate binding and transcription in a dose-dependent way in vitro. IMT1 reduces deoxynucleoside triphosphate levels and citric acid cycle intermediates, resulting in a marked depletion of cellular amino acid levels. IMT1 has the potential for mitochondrial transcription disorders related diseases.
In Vitro
IMT1 (0.00001-10 μM; 0-168 h) has a dose-dependent decrease in cell viability in A2780, A549 and HeLa cells. IMT1 shows a strong decrease in cell viability in about one third of the cancer cell lines, 89 cancer cell lines and primary cells (IMR90 lung fibroblasts and human peripheral blood mononuclear cells (PBMCs)), whereas primary cells remained unresponsive. IMT1 (0.01-10 μM; for 24-200 h) causes a dose-dependent decrease in the levels of mitochondrial transcripts and gradual depletion of mtDNA in HeLa cells. There is a dose-dependent decrease in the levels of subunits (NDUFB8, UQCRC2 and COXI) of respiratory chain complexes I, III and IV. IMT1 reveals a time-dependent and marked increase in the levels of mono- and diphosphate nucleotides that results in a considerable increase in the AMP/ATP ratio and levels of phosphorylated AMPK in A2780 cells. IMT1 severely impairs mtDNA gene expression in A2780 cells that express wild-type POLRMT, whereas cells that express mutant POLRMT (L796Q or L816Q) are resistant. POLRMT is essential for mtDNA transcription and biogenesis of the oxidative phosphorylation (OXPHOS) system. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Viability AssayCell Line: A2780, A549 and HeLa cells Concentration: 0.00001-10 μM Incubation Time: 0-168 hours Result: Had a dose-dependent decrease in cell viability in A2780, A549 and HeLa cells, but had not cytotoxic to human PBMCs or pooled primary human hepatocytes.
