General description

A cell-permeable nitrobenzylidene-thiobarbiturate compound that directly targets the hydrophobic core of Mad2 and selectively disrupts Mad2-Cdc20 complex formation. Shown to dose-dependently inhibit the interaction of Mad2 to Mad2-binding-peptide (Mbp1; IC₅₀ ~ 10.0 µM & K_d = 200 nM). Suggested to covalently modify Mad2-Cys¹⁴⁹ via a reversible Michael adduct formation. Significantly reduces the mitotic duration in paclitaxel (0.5 µM; Cat. No. 580555)-treated HeLa cells (25 µM of M2I-1) and impairs mitotic spindle assembly checkpoint (SAC) function.
