Abstract
Metalloenzymes are central to a wide range of essential biological activities, including nucleic acid modification, protein degradation, and many others. The role of metalloenzymes in these processes also makes them central for the progression of many diseases and, as such, makes metalloenzymes attractive targets for therapeutic intervention. Increasing awareness of the role metalloenzymes play in disease and their importance as a class of targets has amplified interest in the development of new strategies to develop inhibitors and ultimately useful drugs. In this Review, we provide a broad overview of several drug discovery efforts focused on metalloenzymes and attempt to map out the current landscape of high-value metalloenzyme targets.

ADAM protease inhibitors reduce melanogenesis by regulating PMEL17 processing in human melanocytes. J Dermatol Sci 2015; 78:133-42.

Abstract
BACKGROUND ADAMs (a disintegrin and metalloprotease) are a family of proteases involved in ectodomain shedding that play a role in various biological processes such as cell adhesion and migration. ADAM10 and ADAM17 are suggested to be involved in pigmentary disorders. OBJECTIVE We examined the effect of ADAM protease inhibitors on the modulation of melanogenesis in normal human epidermal melanocytes (NHEM). METHODS NHEMs and B16F10 treated with ADAM protease inhibitors were analyzed. AlamarBlue cell proliferation assay, melanin content assay, tyrosinase activity assay, Western blotting analysis, electron microscopic analysis, and RNA interference were employed. RESULTS In NHEMs, melanin content was reduced by treatment with ADAM protease inhibitors. The inhibitors did not change the protein expression of tyrosinase, TRP-1, and MITF. In B16F10 cells, treatment of the cells with ADAM protease inhibitor diminished the α-MSH-induced increase in melanin content. Electron microscopy showed that the number of fibrillar and mature melanosomes was significantly reduced and that the vacuolar compartments were filled with dense unstructured aggregates after treatment with ADAM protease inhibitors. We therefore focused on the processing of PMEL17, a melanosomal glycoprotein that forms a fibrillar matrix on which melanin gets deposited. Proteolytic processing of PMEL17 is required to form functional fibrils during melanogenesis. Recently, γ-secretase and β-site amyloid precursor protein-cleaving enzyme 2 (BACE2) were found to cleave PMEL17. We found that ADAM protease inhibitors exerted effects on the processing of C-terminal and N-terminal fragments of PMEL17. Using BACE2 siRNA and γ-secretase inhibitor, we showed that ADAM protease inhibitor affected PMEL17 processing in a γ-secretase and BACE2-independent mechanism. CONCLUSION Several proteases, including ADAM proteases, can contribute to the formation of fibrils and their assembly into sheets in melanosomes.

Abstract
INTRODUCTION Tumor necrosis factor-α (TNF-α) is a key player in inflammation and joint damage in rheumatoid arthritis (RA). One treatment approach to exclude TNF-α from the biological system is by inhibiting tumor necrosis factor-alpha converting enzyme (TACE), the enzyme responsible for the production of its active form. To date, a number of TACE inhibitors have been reported in the literature from various strategies and methods. AREAS COVERED The following article presents the design and development strategies for the discovery of novel TACE inhibitors which could be of therapeutic utility for the alleviation of inflammatory conditions. The review is based on literature of the subject from 2005 onward. EXPERT OPINION Discovery of a selective TACE inhibitor has remained a major goal for many academic and pharmaceutical industrial research laboratories for quite some time. Identification of selective TACE inhibitors has proved elusive until recently due to structural similarities between TACE and MMPs. The differences in the shape and size of the S1' pocket of TACE and MMPs could be exploited to design selective TACE inhibitors devoid of any MMP inhibitory activity in the near future. It would be a Herculean task to develop a specific TACE inhibitor for clinical treatment of RA because binding subsites of TACE and MMPs are quite similar. However, developments taking place currently in the field as well as in the application of molecular modeling techniques at a wider scale could yet provide clinically useful selective TACE inhibitors in the not too distant future.

Abstract
In the present study, we investigated zinc binding groups (ZBGs) using the coordinates of protein-ligand complex structures obtained from the Protein Data Bank. The distance from the zinc to the nearest ligand atom was measured to determine whether the atom was part of the ZBG. The most frequently found ZBG was carboxylate, followed by sulfonamide, hydroxamate, and phosphonate/phosphate. Because it was found that few heteroatoms, such as nitrogen, oxygen, and sulfur atoms, interacted with zinc, ideal distances between the zinc and these heteroatoms were identified. Whereas carboxylates bound to the zinc via both monodentate and bidentate interactions, the hydroxamates bound dominantly in a bidentate manner. These results will aid in the design of new inhibitors with the potential to interact with zinc in the target protein.

Abstract
We investigated the molecular basis of specificity for the interaction between tumor necrosis factor-alpha converting enzyme (TACE) and peptidomimetic inhibitors. Four novel peptidomimetic TACE inhibitors (8a-d) were designed and synthesized by introducing a substituted sulfur group and a hydrophobic group to a novel matrix metalloprotease (MMP) inhibitor. Inhibition was determined by in vitro lipopolysaccharide (LPS) cytotoxicity tests in HL-60 cell lines and by measuring the expression of mTNF-alpha using FCM techniques and immunohistochemistry in vivo. We simulated the interaction of the inhibitors with the 3D structure of the TACE active site in the Brookhaven Protein Database (PDB). The four inhibitors (8a-d) inhibited activity by 9.1%, 54.5%, 27.3%, and 54.5%, respectively. 8b and 8d showed significant in vitro inhibition in cytotoxicity tests, which corresponded to the molecular docking results. 8d also showed inhibitory activity in vivo. We explored the interface between enzyme and substrate by combining bioinformatics with experimental observations to further the development of specific TACE inhibitors to reduce inflammatory responses.

Abstract
TNF-alpha converting enzyme (TACE), a pro-inflammatory cytokine, catalyzes the formation of TNF-alpha from membrane bound TNF-alpha precursor protein. TNF-alpha is believed to play pathophysiological roles in inflammation, anorexia, cachexia, septic shock, viral replication and so on. TNF-alpha is a key player in inflammation and joint damage in rheumatoid arthritis. While a variety of TACE inhibitors have been reported in the literature, a vast majority of these compounds are peptidic and peptide-like compounds that are expected to have bioavailability and pharmacokinetic problems, common to such compounds, limiting their clinical effectiveness. Low molecular mass, long acting, orally bioavailable inhibitors of TACE are, therefore, highly desirable for the treatment of potential chronic diseases mentioned above. A review of patented compounds as TACE inhibitors in drug discovery is given. A selection of interesting patents recorded from 2001 to 2009 is presented. Various novel TACE inhibitors developed by different companies have been discussed.

Abstract
A series of cephalosporin-derived reverse hydroxamates and oximes were prepared and evaluated as inhibitors of representative metallo- and serine-beta-lactamases. The reverse hydroxamates showed submicromolar inhibition of the GIM-1 metallo-beta-lactamase. With respect to interactions with the classes A, C, and D serine beta-lactamases, as judged by their correspondingly low K(m) values, the reverse hydroxamates were recognized in a manner similar to the non-hydroxylated N-H amide side chains of the natural substrates of these enzymes. This indicates that, with respect to recognition in the active site of the serine beta-lactamases, the OC-NR-OH functionality can function as a structural isostere of the OC-NR-H group, with the N-O-H group presumably replacing the amide N-H group as a hydrogen bond donor to the appropriate backbone carbonyl oxygen of the protein. The reverse hydroxamates, however, displayed k(cat) values up to three orders of magnitude lower than the natural substrates, thus indicating substantial slowing of the hydrolytic action of these serine beta-lactamases. Although the degree of inactivation is not yet enough to be clinically useful, these initial results are promising. The substitution of the amide N-H bond by N-OH may represent a useful strategy for the inhibition of other serine hydrolases.

Abstract
Mandelate racemase (MR) catalyzes the 1,1-proton transfer that interconverts the enantiomers of mandelate. The transition state/intermediate analogues N-hydroxyformanilide (K(i)=2.79+/-0.19 microM) and cupferron (K(i)=2.67+/-0.09 microM) are identified as potent competitive inhibitors of MR. The pH-pK(i) profile indicates that MR can bind either the protonated or deprotonated forms of N-hydroxyformanilide, with a 10-fold greater affinity for the latter form.

Abstract
A novel series of achiral TNF-alpha converting enzyme (TACE) inhibitors has been discovered. These compounds exhibited activities from 0.35 to 11nM in a porcine TACE assay and inhibited TNF-alpha production in an LPS-stimulated whole blood assay with an IC(50) value of 23nM for the most potent one. They also have excellent selectivities over related metalloproteases including aggrecanases.

Abstract
N-Formylhydroxylamines, also known as reverse- or retro-hydroxamates, have become of significant interest in the recent past as inhibitors of metalloenzymes. Although solution-phase synthetic routes to such compounds have been reported, these are often lengthy and involve purification at each stage. Herein, novel three-step solid-phase synthetic approaches are described that enable libraries of such compounds to be produced in a convergent and efficient manner using commercially available starting materials.
