| Description | ZYN57939 (MTR-106) is RNA polymerase I inhibitor for treating RNA polymerase I- mediated diseases. ZYN57939 showed inhibitory activity with IC50 of 0.855 μM against human HT- 29 cancer cell lines.  | 
| In vitro | MTR-106, stabilizes DNA G-quadruplexes in vitro.?MTR-106 displayed significant antiproliferative activity in homologous recombination repair (HR)-deficient and PARP inhibitor (PARPi)-resistant cancer cells.?Moreover, MTR-106 increased DNA damage and promoted cell cycle arrest and apoptosis to inhibit cell growth.  | 
| In vivo | ZYN57939 oral and i.v. administration significantly impaired tumor growth in BRCA-deficient xenograft mouse models.However, ZYN57939 showed modest activity against talazoparib-resistant xenograft models.In rats, the drug rapidly distributes to tissues within 5 min, and its average concentrations were 12-fold higher in the tissues than in the plasma.Overall, ZYN57939 as a novel G-quadruplex stabilizer with high tissue distribution, and it may serve as a potential anticancer agent.  |
