Inhibitors of matrix metalloproteinases (MMPs) are comprised of a zinc-binding functional group which targets the inhibitor to the catalytic zinc within the active site of the enzyme, and a peptidomimetic portion which increases the affinity of the inhibitor to the enzyme active site, thereby mimicking the natural peptide substrate. The majority of first generation inhibitors of MMPs were first described in the literature in the late 1980s. These matrix metalloproteinase inhibitors (MMPIs) were designed as inhibitors of fibroblast interstitial collagenase (MMP-1) and consisted of a hydroxamic acid as the zinc-binding functional group and a LeuLeuPhe or LeuPhe as a mimetic of the preferred substrate of MMP-1 (Fig. 1) (1). These early compounds were often broad-spectrum MMPIs, with potent inhibitory activity against fibroblast collagenase, stromelysin-1 (MMP-3), and the gelatinases (MMP-2 and MMP-9). As peptides, they suffered from low bioavailability and rapid metabolism, and as hydroxamic acids they were potentially mutagenic.

    An Evans chiral auxiliary route starting with N-acylation of (R)-(+)-4-Isopropyl-2-oxazolidinone with 4-methylpentanoyl chloride followed by a-alkylation with tert-Butyl bromoacetate and ending with hydrolysis by H2O2/LiOH/H2O/THF followed by TFA/CH2C12 yielded (S)-2-isobutyl succinic acid. This enantiomerically pure acid was cyclized to the anhydride by treatment with acetyl chloride and then used in a Friedel-Crafts reaction with 4chlorobiphenyl as described in patent reference 11 to yield the S isomer of compound 2. Similarly, (S)-(-)-4-Isopropyl-2-oxazolidinone led to the R isomer of compound 2. A manuscript to describe the details of these syntheses is in preparation.Google Scholar
