Abstract
The management of patients with type 2 diabetes mellitus (T2DM) is shifting from cardio-centric to weight-centric or, even better, adipose-centric treatments. Considering the downsides of multidrug therapies and the relevance of dipeptidyl peptidase IV (DPP IV) and carbonic anhydrases (CAs II and V) in T2DM and in the weight loss, we report a new class of multitarget ligands targeting the mentioned enzymes. We started from the known α1-AR inhibitor WB-4101, which was progressively modified through a tailored morphing strategy to optimize the potency of DPP IV and CAs while losing the adrenergic activity. The obtained compound 12 shows a satisfactory DPP IV inhibition with a good selectivity CA profile (DPP IV IC50: 0.0490 μM; CA II Ki 0.2615 μM; CA VA Ki 0.0941 μM; CA VB Ki 0.0428 μM). Furthermore, its DPP IV inhibitory activity in Caco-2 and its acceptable pre-ADME/Tox profile indicate it as a lead compound in this novel class of multitarget ligands.

Abstract
The use of metal-binding pharmacophores (MBPs) in fragment-based drug discovery has proven effective for targeted metalloenzyme drug development. However, MBPs can still suffer from pharmacokinetic liabilities. Bioisostere replacement is an effective strategy utilized by medicinal chemists to navigate these issues during the drug development process. The quinoline pharmacophore and its bioisosteres, such as quinazoline, are important building blocks in the design of new therapeutics. More relevant to metalloenzyme inhibition, 8-hydroxyquinoline (8-HQ) and its derivatives can serve as MBPs for metalloenzyme inhibition. In this report, 8-HQ isosteres are designed and the coordination chemistry of the resulting metal-binding isosteres (MBIs) is explored using a bioinorganic model complex. In addition, the physicochemical properties and metalloenzyme inhibition activity of these MBIs were investigated to establish drug-like profiles. This report provides a new group of 8-HQ-derived MBIs that can serve as novel scaffolds for metalloenzyme inhibitor development with tunable, and potentially improved, physicochemical properties.

Abstract
Certain cancers exhibit upregulation of DNA interstrand crosslink repair pathways, which contributes to resistance to crosslinking chemotherapy drugs and poor prognoses. Inhibition of enzymes implicated in interstrand crosslink repair is therefore a promising strategy for improving the efficacy of cancer treatment. One such target enzyme is SNM1A, a zinc co-ordinating 5'-3' exonuclease. Previous studies have demonstrated the feasibility of inhibiting SNM1A using modified nucleosides appended with zinc-binding groups. In this work, we sought to develop more effective SNM1A inhibitors by exploiting interactions with the phosphate-binding pocket adjacent to the enzyme's active site, in addition to the catalytic zinc ions. A series of nucleoside derivatives bearing phosphate moieties at the 5'-position, as well as zinc-binding groups at the 3'-position, were prepared and tested in gel-electrophoresis and real-time fluorescence assays. As well as investigating novel zinc-binding groups, we found that incorporation of a 5'-phosphate dramatically increased the potency of the inhibitors.

Abstract
Chronic obstructive pulmonary disease (COPD) is a lung disorder characterized by progressive airflow obstruction associated with inflammation and emphysema, and it is currently one of the leading causes of death worldwide. Recent studies with genetically engineered mice reported that during pulmonary inflammation, basophil-derived interleukin-4 can act on lung-infiltrating monocytes causing aberrant expression of the matrix metalloproteinase-12 (MMP-12). MMP-12 activity in turn causes the destruction of alveolar walls leading to emphysema, making it potentially a valid target for pharmacological intervention. Using nuclear magnetic resonance (NMR)- and structure-based optimizations, the current study reports on the optimized novel, potent, and selective MMP-12 inhibitors with single-digit nanomolar affinity in vitro and in vivo efficacy. Using a murine model of elastase-induced emphysema we demonstrated that the most potent agents exhibited a significant decrease in emphysema-like pathology compared to vehicle-treated mice, thus suggesting that the reported agents may potentially be translated into novel therapeutics for the treatment of COPD.

Abstract
Immobilized metal-ion affinity chromatography (IMAC) used to purify recombinant proteins features a resin-bound 1:1 Ni(II)-iminodiacetic acid (IDA) complex. This hemi-saturated Ni(II)-IDA system containing exchangeable sites at the metal ion is re-cast as a surrogate of a coordinatively-unsaturated metalloenzyme active site, with utility for selecting compounds with metal-binding groups from mixtures as potential metalloenzyme inhibitors. Exchanging Ni(II) for other metal ions could broaden the scope of metalloenzyme target. This work examined the performance of Cu(II)-, Fe(III)-, Ga(III)-, Ni(II)-, or Zn(II)-IMAC resins to reversibly bind experimental or clinical metalloenzyme inhibitors of Zn(II)-ACE1, Zn(II)-HDAC, Fe(II)/(III)-5-LO or Cu(II)-tyrosinase from a curated mixture (1-17). Each IMAC system gave a distinct selection profile. The Zn(II)-IMAC system selectively bound the thiol-containing Zn(II)-ACE1 inhibitors captopril and omapatrilat, and the Fe(III)-IMAC system selectively bound the Fe(II)/(III)-5-LO inhibitor licofelone, demonstrating a remarkable IMAC-metalloenzyme metal ion match. IMAC provides a simple, water-compatible platform, which could accelerate metalloenzyme inhibitor discovery.

Abstract
Benzimidazoles are common in nature, medicines, and materials. Numerous strategies for preparing 2-arylbenzimidazoles exist. In this work, 1,2-disubstituted benzimidazoles were prepared from various mono- and disubstituted ortho-phenylenediamines (OPD) by iron-catalyzed oxidative coupling. Specifically, O2 and FeCl3·6H2O catalyzed the cross-dehydrogenative coupling and aromatization of diarylmethyl and dialkyl benzimidazole precursors. N,N'-Disubstituted-OPD substrates were significantly more reactive than their N,N-disubstituted isomers, which appears to be relative to their propensity for complexation and charge transfer with Fe3+. The reaction also converted N-monosubstituted OPD substrates to 2-substituted benzimidazoles; however, electron-poor substrates produce 1,2-disubstituted benzimidazoles by intermolecular imino-transfer. Kinetic, reagent, and spectroscopic (UV-vis and EPR) studies suggest a mechanism involving metal-substrate complexation, charge transfer, and aerobic turnover, involving high-valent Fe(IV) intermediates. Overall, comparative strategies for the relatively sustainable and efficient synthesis of 1,2-disubstituted benzimidazoles are demonstrated.

Abstract
Members of the matrix metalloproteinase (MMP) family have biological functions that are central to human health and disease, and MMP inhibitors have been investigated for the treatment of cardiovascular disease, cancer and neurodegenerative disorders. The outcomes of initial clinical trials with the first generation of MMP inhibitors proved disappointing. However, our growing understanding of the complexities of the MMP function in disease, and an increased understanding of MMP protein architecture and control of activity now provide new opportunities and avenues to develop MMP-focused therapies. Natural products that affect MMP activities have been of strong interest as templates for drug discovery, and for their use as chemical tools to help delineate the roles of MMPs that still remain to be defined. Herein, we highlight the most recent discoveries of structurally diverse natural product inhibitors to these proteases.

Overcoming imatinib resistance in chronic myelogenous leukemia cells using non-cytotoxic cell death modulators. Eur J Med Chem 2019; 185:111748.

Abstract
Recent studies examined the possibility to overcome imatinib resistance in chronic myeloid leukemia (CML) patients by combination therapy with peroxisome proliferator-activated receptor gamma (PPARγ) ligands. Pioglitazone, a full PPARγ agonist, improved the survival of patients by the gradual elimination of the residual CML stem cell pool. To evaluate the importance of the pharmacological profile of PPARγ agonists on the ability to circumvent resistance, the partial PPARγ agonist 4'-((2-propyl-1H-benzo[d]imidazol-1-yl)methyl)-[1,1'-biphenyl]-2-carboxylic acid, derived from telmisartan, and other related derivatives were investigated. The 4-substituted benzimidazole derivatives bearing a [1,1'-biphenyl]-2-carboxamide moiety sensitized K562-resistant cells to imatinib treatment. Especially the derivatives 18a-f, which did not activate PPARγ to more than 40% at 10 μM, retrieved the cytotoxicity of imatinib in these cells. The cell death modulating properties were higher than that of pioglitazone. It is of interest to note that all novel compounds were not cytotoxic neither on non-resistant nor on resistant cells. They exerted antitumor potency only in combination with imatinib.

Abstract
Transmembrane-type 2 matrix metalloproteinase (MT2-MMP) degrades connective extracellular matrix between cells and enables tumor cells to migrate and metastasize, making this substance a potential therapeutic target in various diseases. In this work, the interactions between MT2-MMP and common trivalent metal ions, including aluminum (Al3+) and ferrum (Fe3+) ions, were investigated. Enzymatic detection revealed that Al3+ and Fe3+ strongly inhibited the MT2-MMP. Fluorescence spectrography elucidated a static quenching interaction between the negatively charged amino acids on MT2-MMP and the inhibitory trivalent metal ions, indicating that a stable complex was formed between MT2-MMP and metal ions. In addition, fluorescence data and molecular modeling analysis of the binding characteristics revealed that one trivalent metal ion bound with a protein in the stable complex formation process. The potential inhibitory effect of Al3+ on MT2-MMP was further examined in an MT2-MMP-overexpressed cell line, HT1080, by using flow cytometry. As a result, Al3+ can promote HT1080 cell apoptosis in a micromolar concentration-dependent manner. This work illustrated that common trivalent metal ions can potentially inhibit MT2-MMP-related tumors.

Abstract
We have recently proposed a novel drug discovery approach based on biophysical screening of focused positional scanning libraries in which each element of the library contained a common binding moiety for the given target or class of targets. In this Letter, we report on the implementation of this approach to target metal containing proteins. In our implementation, we first derived a focused positional scanning combinatorial library of peptide mimetics (of approximately 100,000 compounds) in which each element of the library contained the metal-chelating moiety hydroxamic acid at the C-terminal. Screening of this library by nuclear magnetic resonance spectroscopy in solution allowed the identification of a novel and selective compound series targeting MMP-12. The data supported that our general approach, perhaps applied using other metal chelating agents or other initial binding fragments, may result very effective in deriving novel and selective agents against metalloenzyme.

Abstract
Matrix metalloproteinases (MMPs) are an important family of zinc-containing enzymes with a central role in many physiological and pathological processes. Although several MMP inhibitors have been synthesized over the years, none reached the market because of off-target effects, due to the presence of a zinc binding group in the inhibitor structure. To overcome this problem non-zinc-binding inhibitors (NZIs) have been recently designed. In a previous article, a virtual screening campaign identified some hydroxynaphtyridine and hydroxyquinoline as MMP-2 non-zinc-binding inhibitors. In the present work, simplified analogues of previously-identified hits have been synthesized and tested in enzyme inhibition assays. Docking and molecular dynamics studies were carried out to rationalize the activity data.

Abstract
This study evaluated the inhibition of matrix metalloproteases (MMPs) and cellular responses elicited by gold (Au) and platinum (Pt) nanoparticles (NPs). The interaction of MMP-1 and NPs was evaluated using an MMP assay kit. The cultured L929 cells were exposed to various concentrations of NPs. The cellular responses to NPs were examined using a cytotoxicity assay (that evaluated cell viability and lactic dehydrogenase production), real-time polymerase chain reaction (RT-qPCR), and transmission electron microscopy. Both types of NPs, when used at concentrations above 10 μg ml(-1), inhibited MMP-1 activity. No cytotoxic effects were found when the cells were exposed to AuNPs. In contrast, PtNPs, at both 100 and 400 μg ml(-1), induced cytotoxicity. No inflammatory responses (production of interleukin-6 and tumor necrosis factor-alpha) to NPs were identified by RT-qPCR. The negative surface charge of NPs (COOH(-)) binds to the Zn(2+) of the MMP active center by chelation, leading to MMP inhibition. Gold nanoparticles are plausible candidates for MMP inhibitors in resin-bonding materials because they effectively inhibit MMP-1 activity without cytotoxic or inflammatory effects.

Abstract
Matrix metalloprotease (MMP) inhibitors improve the longevity of dental adhesives/tooth bonds; however, biocompatibility is required for their clinical use. This study evaluated the inhibition of MMPs and toxicity of two gold (AuNPs) and platinum nanoparticles (PtNPs) as possible compounds for use in dental adhesives. The MMP assay for studying the interaction of MMPs and nanoparticles (NPs) was evaluated by an MMP assay kit and gelatin zymography. Cultured L929 fibroblast cells or RAW264 macrophages were exposed to NPs. The cellular responses to NPs were examined using cytotoxic (cell viability) and genotoxic assays (comet assay), and transmission electron microscopic (TEM) analysis. The mechanical properties (elastic modulus) of the experimental resin loaded with NPs were examined using thermomechanical analysis. All NPs inhibited MMP activity at relatively low concentrations. The NPs inhibit MMPs by chelating with the Zn(2+) bound in the active sites of MMPs. No cytotoxic and genotoxic effects were found in AuNPs, whereas the PtNPs possessed both adverse effects. In TEM analysis, the NPs were localized mainly in lysosomes without penetration into nuclei. The mechanical properties of the resins increased when AuNPs were added in resins, but not by PtNPs. AuNPs are attractive candidates to inhibit MMPs and improve the mechanical properties of resins without cytotoxic/genotoxic effects to cells, and therefore should be suitable for applications in adhesive resin systems.

Abstract
Nanoparticles (NPs) are currently the focus of considerable attention for dental applications; however, their biological effects have not been fully elucidated. The long-term, slow release of matrix metalloproteases (MMPs) digests collagen fibrils within resin-dentin bonds. Therefore, MMP inhibitors can prolong the durability of resin-dentin bonds. However, there have been few reports evaluating the combined effect of MMP inhibition and the cytotoxic effects of NPs for dentin bonding. The aim of this study was to evaluate MMP inhibition and cytotoxic responses to gold (AuNPs) and platinum nanoparticles (PtNPs) stabilized by polyvinylpyrrolidone (PVP) in cultured murine macrophages (RAW264) by using MMP inhibition assays, measuring cell viability and inflammatory responses (quantitative reverse transcription polymerase chain reaction [RT-qPCR]), and conducting a micromorphological analysis by fluorescence and transmission electron microscopy. Cultured RAW264 cells were exposed to metal NPs at various concentrations (1, 10, 100, and 400 µg/mL). AuNPs and PtNPs markedly inhibited MMP-8 and MMP-9 activity. Although PtNPs were cytotoxic at high concentrations (100 and 400 µg/mL), no cytotoxic effects were observed for AuNPs at any concentration. Transmission electron microscopy images showed a significant nonrandom intercellular distribution for AuNPs and PtNPs, which were mostly observed to be localized in lysosomes but not in the nucleus. RT-qPCR analysis demonstrated inflammatory responses were not induced in RAW264 cells by AuNPs or PtNPs. The cytotoxicity of nanoparticles might depend on the core metal composition and arise from a “Trojan horse” effect; thus, MMP inhibition could be attributed to the surface charge of PVP, which forms the outer coating of NPs. The negative charge of the surface coating of PVP binds to Zn2+ from the active center of MMPs by chelate binding and results in MMP inhibition. In summary, AuNPs are attractive NPs that effectively inhibit MMP activity without cytotoxicity or inflammatory responses.

Abstract
In recent years many metalloproteases (MPs) have been shown to play important roles in the development of various pathological conditions. Although most of the literature is focused on matrix MPs (MMPs), many other MPs have been demonstrated to be involved in the degradation of peptides or proteins whose accumulation and dyshomeostasis are considered as being responsible for the development of conformational diseases, i.e., diseases where non-native protein conformations lead to protein aggregation. It seems clear that, at least in principle, it must be possible to control the levels of many aggregation-prone proteins not only by reducing their production, but also by enhancing their catabolism. Metal complexes that can perform this function were designed and tested according to at least two different strategies: (i) intervening on the endogenous MPs by directly or indirectly modulating their activity; (ii) acting as artificial MPs, replacing or synergistically functioning with endogenous MPs. These two different bioinorganic approaches are widely represented in the current literature and the aim of this review is to rationally organize and discuss both of them so as to give a critical insight into these approaches and highlighting their limitations and future perspectives.

Abstract
The HOPO vinyl sulfonamide 3 and the corresponding HOPO acrylamide 10, were easily prepared by short synthetic sequences. Investigation of the aza-Michael reactions of these linkers showed that they proceed at a higher rate in solvent systems containing water. The scope and limits of the aza-Michael reactions of 3 and 10 were examined. Reagents 3 and 10 reacted cleanly with piperazine to give the corresponding adducts which were deprotected to give the di-HOPO ligands 7 and 16. Reaction of HOPO acrylamide 10 with 1,4,7-triazacyclononane gave the tris-adduct 17 which was deprotected to give the desired tris-HOPO ligand 18. Overall, the aza-Michael reactions of 3 and 10 appear to be governed not only by the solvent but also by the nature of the amine and the solubility of the reaction intermediates.

Abstract
Pan assay interference compounds (PAINS) are readily discovered in any bioassay and can appear to give selective and optimisable hits. The most common PAINS can be readily recognised by their structure. However, there are compounds that closely resemble PAINS that are not specifically recognised by the PAINS filters. In addition, highly reactive compounds are not encoded for in the PAINS filters because they were excluded from the high-throughput screening (HTS) library used to develop the filters and so were never present to provide indicting data. A compounding complication in the area is that very occasionally a PAINS compound may serve as a viable starting point for progression. Despite such an occasional example, the literature is littered with an overwhelming number of examples of compounds that fail to progress and were probably not optimisable in the first place, nor useful tool compounds. Thus it is with great caution and diligence that compounds possessing a known PAINS core should be progressed through to medicinal chemistry optimisation, if at all, as the chances are very high that the hits will be found to be non-progressable, often after a significant waste of resources.
