MU147
Based on 1 Customer Validation
MU147 is an MRE11 nuclease inhibitor and chemical probe with anticancer activity, exhibiting IC50 values of 3.7 μM and 0.8 μM against the nuclease activity of human MRE11 and the MRN complex, respectively. MU147 inhibits MRE11 exonuclease and endonuclease activities, preventing MRN-dependent DNA end resection and nascent DNA degradation at stalled replication forks in BRCA2-deficient cells. MU147 delays the DNA damage repair process, inhibits homologous recombination and alternative non-homologous end joining, downregulates ionizing radiation- or camptothecin-induced RPA/RPA32 phosphorylation, and reduces survival of BRCA2-deficient cells. MU147 directly binds MRE11 in cells and impairs its recruitment to damage foci. MU147 can be used in cancer-related research.

IC50 & Target
MRE11[1]
In Vitro
MU147 (25 μM; 72 h) inhibits MRE11-dependent HR and A-NHEJ double-strand break repair in U2OS and HEK-293T reporter cells[1].
MU147 (25-50 μM) inhibits DNA end resection and RPA32 S4/S8 phosphorylation in CPT (HY-16560)-exposed U2OS cells, with an IC50 of 19 μM for RPA32 pS4/S8 foci, and reduces pRPA S4/S8 and γH2AX immunoblot signals[1].
MU147 (25 μM; co-exposure with 4 mM HU (HY-B0313) for 4 hours) rescues nascent DNA degradation at stalled replication forks in BRCA2-deficient DLD1 cells[1].
MU147 (100 μM; 60 minutes) does not directly bind FEN1 in U2OS cells under CETSA conditions[1].
