NSC-405020 is a novel small molecule inhibitor of membrane type-I matrix metalloproteinase (MT1-MMP) that specifically targets the hemopexin (PEX) domain rather than the catalytic domain of MT1-MMP with 50% inhibition concentration IC50 value larger than 100 μmol/L and does not inhibit the catalytic activity of MT1-MMP or MMP-2. NSC-405020 directly interacts with and binds to PEX in a vicinity of Met-328, Arg-330, Asp-376, Met-22 and Ser-470 of the druggable pocket in the full-length MT1-MMP structure, which affects the conformation and flexibility of blades I to IV of the β-propeller resulting in the decrease of the PEX-dependent homodimerization of cellular MT1-MMP. NSC-405020 dose not affect the ability of MT1-MMP to activate MMP-2 but its ability to degrade COL-I.
