ML-216 is a potent and selective inhibitor of BLM (Bloom) helicase (IC₅₀ = 1.8 μM); it displays 28-fold selectivity against the related helicases RECQ1, RECQ5, and E. coli UvrD (IC50s ≥ 50 μM). At 25-50 μM, ML-216 has been shown to dose-dependently inhibit the proliferation of BLM-expressing PSNF5 fibroblast cells but not BLM-deficient PSNG13 fibroblast cells.
