General description

A cell-permeable, bis-catechol containing, m-phenylenediamide compound that displays anti-proliferative properties. Acts as a potent, reversible inhibitor of telomerase activity (IC50 = 670 nM, TRAP lysate prepared from U937 cells). Prolonged treatment with MST-312 has been reported to result in telomere shortening and growth arrest in U937 cells. Does not inhibit the activity of Taq DNA polymerase (IC50 >3 µM).
