Applications

RNA polymerase I inhibitor

Functions

First-in-class selective RNA polymerase I inhibitor, suppressing Pol I transcription in MV 4;11 myelomonocytic leukemia cells and SR immunoblastic lymphoma cells with EC₅₀ values of 95 and 135 nM respectively and demonstrating 200-fold selectivity over Pol II. Activates the DNA damage response. It induces a rapid accumulation of cytosolic DNA which results in upregulation of STING. Acts as a potent immunosuppressant inhibiting T cell-mediated alloimmunity and representing a novel class of immunosuppressant.

Application Procedures

First dissolved in DMSO (10 mg/ml), then diluted to aqueous buffer. Solutions in DMSO may be stored at -20°C for up to 3 months.

Research use only.
