| Bioactivity | PFM39, a Mirin analog, is a potent and selective MRE11 exonuclease inhibitor. PFM39 inhibits phosphate rotation for dsDNA exonuclease activity. PFM39 does not inhibit TmMre11 or human MRE11/MRN endonuclease activity[1]. |
| Invitro | PFM39 (100 μM) treatment impairs G2-phase double-strand break (DSB) repair in 1BR3-hTERT fibrolasts following ionizing irradiation (IR)[1]. PFM39 (50 μM) inhibits homologous recombination (HR) without significantly increasing NHEJ[1]. |
