Discovery of Highly Potent and Selective Matrix Metalloproteinase‑7 Inhibitors by Hybridizing the S1′ Subsite Binder with Short Peptides
Matrix metalloproteinase-7 (MMP-7) has emerged as a protein
playing
important roles in both physiological and pathophysiological processes.
Despite the growing interest in MMP-7 as a potential therapeutic target
for diseases including cancer and fibrosis, potent and selective MMP-7
inhibitors have yet to be identified. Compound 1, previously
reported by Edman and co-workers, binds to the S1′ subsite
of MMP-7, exhibiting moderate inhibitory activity and selectivity.
To achieve both higher inhibitory activity and selectivity, we conceived
hybridizing 1 with short peptides. The initially designed
compound 6, which was a hybrid molecule between 1 and a tripeptide (Ala-Leu-Met) derived from an MMP-2-inhibitory
peptide (APP-IP), showed enhanced MMP-7-inhibitory activity. Subsequent
optimization of the peptide moiety led to the development of compound 18 with remarkable potency for MMP-7 and selectivity over
other MMP subtypes

Discovery of TP0597850: A Selective, Chemically Stable, and Slow Tight-Binding Matrix Metalloproteinase‑2 Inhibitor with a Phenylbenzamide–Pentapeptide Hybrid Scaffold
Matrix metalloproteinase-2 (MMP2) is a zinc-dependent
endopeptidase
and a promising target for various diseases, including cancer and
fibrosis. Herein, we report the discovery of a novel MMP2-selective
inhibitor with high chemical stability and slow tight-binding features.
Based on the degradation mechanism of our small-molecule–peptide
hybrid 1, the tripeptide linker {5-aminopentanoic acid
[Ape(5)]–Glu–Asp} of 1 was replaced by
a shorter linker (γ-D-Glu). Phenylbenzamide was suitable for
the new generation of MMP2 inhibitors as an S1′ pocket-binding
group. The introduction of (4S)-aminoproline dramatically
increased the chemical stability while maintaining high subtype selectivity
because of its interaction with Glu130. TP0597850 (18) exhibited high stability over a wide range of pH values as well
as potent MMP2 inhibition (Ki = 0.034
nM) and ≥2000-fold selectivity determined using the inhibition
constants. A kinetic analysis revealed that it possesses slow tight-binding
nature with a long MMP2 dissociative half-life (t1/2 = 265 min)
