Crystal structure of human MMP-12 in complex with acetohydroxamic acid and a bicyclic inhibitor
Contents |
Overview
Starting from 3-aza-6,8-dioxa-bicyclo[3.2.1]octane scaffold (BTAa) a, virtual library of molecules was generated and screened in silico against, the crystal structure of the Human Macrophage Metalloelastase (MMP-12)., The molecules obtaining high score were synthesized and the affinity for, the catalytic domain of MMP-12 was experimentally proved by NMR, experiments. A BTAa scaffold 20 having a N-hydroxyurea group in position 3, and a p-phenylbenzylcarboxy amide in position 7 showed a fair inhibition, potency (IC50 = 149 microM) for MMP-12 and some selectivity towards five, different MMPs. These results, taken together with the X-ray structure of, the adduct between MMP-12, the inhibitor 20 and the acetohydroxamic acid, (AHA), suggest that bicyclic scaffold derivatives may be exploited for the, design of new selective matrix metalloproteinase inhibitors (MMPIs).
