Matrix metalloproteinases (MMPs) are attractive biological targets that play a key role in many physiopathological processes such as degradation of extracellular matrix proteins, release and cleavage of cell-surface receptors, tumour progression, homeostatic regulation and innate immunity. A series of 5-hydroxy, 5-substituted pyrimidine-2,4,6-triones were rationally designed, prepared and tested as inhibitors of gelatinases MMP-2 and MMP-9 and collagenase MMP-8. On one side, the presence of the 5-hydroxyl group, that represents an typical feature of this class of compounds, ensured an attractive pharmacokinetic profile while on the other suitably substituted biaryl molecular fragments, attached to position 5 through a ketomethylene linker, guaranteed favourable interaction in the deep region of the S1′ enzymatic subsite. This rational design led to the discovery of highly potent MMP inhibitors. In particular, biphenyl derivatives bearing at the para position COCH3 and OCF3 substituents permitted to inhibit gelatinases MMP-2 and MMP-9, with IC50 values as low as 30 nM and 21 nM, respectively, whereas the introduction at the same position of the bulkier SO2CH3 group afforded a potent collagenase MMP-8 inhibitor with an IC50 value equal to 66 nM. Molecular docking simulations allowed us to elucidate key interactions driving the binding of the top active compounds towards their preferred MMP target.
