  • PubMed Abstract: 

    After the disappointment of clinical trials with early broad spectrum synthetic inhibitors of matrix metalloproteinases (MMPs), the field is now resurging with a new focus on the development of selective inhibitors that fully discriminate between different members of the MMP family with several therapeutic applications in perspective. Here, we report a novel class of highly selective MMP-12 inhibitors, without a phosphinic zinc-binding group, designed to plunge deeper into the S(1)' cavity of the enzyme. The best inhibitor from this series, identified through a systematic chemical exploration, displays nanomolar potency toward MMP-12 and selectivity factors that range between 2 and 4 orders of magnitude toward a large set of MMPs. Comparison of the high resolution x-ray structures of MMP-12 in free state or bound to this new MMP-12 selective inhibitor reveals that this compound fits deeply within the S(1)' specificity cavity, maximizing surface/volume ratios, without perturbing the S(1)' loop conformation. This is in contrast with highly selective MMP-13 inhibitors that were shown to select a particular S(1)' loop conformation. The search for such compounds that fit precisely to preponderant S(1)' loop conformation of a particular MMP may prove to be an alternative effective strategy for developing selective inhibitors of MMPs.
