Phosphinic acid-based inhibitors of MMP-13 have been investigated with the aim of identifying potent inhibitors with high selectivity versus MMP-1. Independent variation of the substituents on a P(1)' phenethyl group and a P(2) benzyl group improved potencies in both cases around 3-fold over the unsubstituted parent. Combining improved P(1)' and P(2) groups into a single molecule gave an inhibitor with a 4.5 nM IC(50) against MMP-13 and which is 270-fold selective over MMP-1.
