Synthetic triple-helical peptides (THPs) are used for the design and synthesis of triple-helical transition state analog inhibitors. These inhibitors feature a phosphonate ester or phosphinic moiety in place of the scissle bond. These groups inhibit MMPs, and methods been developed for their convenient incorporation within a peptide sequence by solid-phase methods.

Ces inhibiteurs présentent un ester de phosphonate ou un groupe fonctionnel phosphinique à la place du lien scissile. Ces groupes sont inhibiteurs de MMP, et des procédés ont été développés pour leur incorporation appropriée au sein d'une séquence peptidique par des procédés en phase solide.

MMP inhibitors. In the present study, a phosphinate transitionstate analogue has been incorporated within a triple-helical peptide template. The template sequence was based on the alpha1(V)436-450 collagen region, which is hydrolyzed at the Gly(439)-Val(440) bond selectively by MMP-2 and MMP-9. The phosphinate acts as a tetrahedral transitionstate analogue, which mimics the water-bound peptide bond
