Captopril/enalapril inhibit promiscuous esterase activity of carbonic anhydrase at micromolar concentrations: An in vitro study. Chem Biol Interact 2017; 265:24-35.

Abstract
The inhibitory activity of captopril, a thiol-containing competitive inhibitor of the angiotensin-converting enzyme, ACE, against esterase activity of carbonic anhydrase, CA was investigated. This small molecule, as well as enalapril, was selected in order to represents both thiol and carboxylate, as two well-known metal binding functional groups of metalloprotein inhibitors. Since captopril, has also been observed to inhibit other metalloenzymes such as tyrosinase and metallo-beta lactamase through binding to the catalytic metal ions and regarding CA as a zinc-containing metallo-enzyme, in the current study, we set out to determine whether captopril/enalapril inhibit CA esterase activity of the purified human CA II or not? Then, we revealed the inhibitors' potencies (IC50, Ki and Kdiss values) and also mode of inhibition. Our results also showed that enalapril is more potent CA inhibitor than captopril. Since enalapril represents no sulfhydryl moiety, thus carboxylate group may have a determinant role in inhibiting of CA esterase activity, the conclusion confirmed by molecular docking studies. Additionally, since CA inhibitory potencies of captopril/enalapril were much lower than those of classic sulfonamide drugs, the findings of the current study may explain why these drugs exhibit no effective CA inhibition at the concentrations reached in vivo and also may shed light on the way of generating new class of inhibitors that will discriminately inhibit various CA isoforms.

Abstract
Metal dyshomeostasis is involved in the pathogenesis and progression of diseases including cancer and neurodegenerative diseases. Metal chelators and ionophores are well known modulators of transition metal homeostasis, and a number of these molecules are in clinical trials. Metal-binding compounds are not the only drugs capable of targeting transition metal homeostasis. This review presents recent highlights in the development of chelators and ionophores for the treatment of cancer and neurodegenerative disease. Moreover, we discuss the development of small molecules that alter copper and iron homeostasis by inhibiting metal transport proteins. Finally, we consider the emergence of metal regulatory factor 1 as a drug target in diseases where it mediates zinc-induced signalling cascades leading to pathogenesis.

Abstract
Tetrazoles are small functional heterocycles that are suited to serve simultaneously as aromatic platform for diversity and as functional interaction motif. Furthermore, the tetrazole ring and its deprotonated tetrazolate counterpart are metal ion complexing ligands that possess a rich variety of binding and bridging modes. We recently demonstrated that fragments containing the tetrazole moiety and a metal chelating hydrazide group are well suited to discover selective screening hits with high ligand efficiency for a given protein target. Here, we report the synthesis and characterization of new polydentate tetrazole-containing screening compounds and their synthetic precursors as well as their deposition in a multipurpose screening library in the frame of the EU-OPENSCREEN network. The pure and well-characterized screening compounds could be useful to aid drug discovery programs for multiple or hitherto undruggable targets by enclosure of under-represented tetrazole derivatives.

The Cell Killing Mechanisms of Hydroxyurea. Genes (Basel) 2016; 7:genes7110099.

Abstract
Hydroxyurea is a well-established inhibitor of ribonucleotide reductase that has a long history of scientific interest and clinical use for the treatment of neoplastic and non-neoplastic diseases. It is currently the staple drug for the management of sickle cell anemia and chronic myeloproliferative disorders. Due to its reversible inhibitory effect on DNA replication in various organisms, hydroxyurea is also commonly used in laboratories for cell cycle synchronization or generating replication stress. However, incubation with high concentrations or prolonged treatment with low doses of hydroxyurea can result in cell death and the DNA damage generated at arrested replication forks is generally believed to be the direct cause. Recent studies in multiple model organisms have shown that oxidative stress and several other mechanisms may contribute to the majority of the cytotoxic effect of hydroxyurea. This review aims to summarize the progress in our understanding of the cell-killing mechanisms of hydroxyurea, which may provide new insights towards the improvement of chemotherapies that employ this agent.

Abstract
Tropolones, such as β-thujaplicin, are small lead-like natural products that possess a variety of biological activities. While the β-substituted natural products and their synthetic analogs are potent inhibitors of human cancer cell growth, less is known about their α-substituted counterparts. Recently, we synthesized a series of α-substituted tropolones including 2-hydroxy-7-(naphthalen-2-yl)cyclohepta-2,4,6-trien-1-one (α-naphthyl tropolone). Here, we evaluate the antiproliferative mechanisms of α-naphthyl tropolone and the related α-benzodioxinyl analog. The α-substituted tropolones inhibit growth of lymphocytic leukemia cells, but not healthy blood cells, with nanomolar potency. Treatment of leukemia cell lines with the tropolone dose-dependently induces apoptosis as judged by staining with annexin V and propidium iodide and Western blot analysis of cleaved caspase 3 and 7. Moreover, pre-treatment of cells with the caspase inhibitor Z-VAD-FMK inhibited the apoptotic effects of the tropolone in two lymphocytic lines. Caspase inhibition also blocked elevated histone acetylation caused by the tropolone, indicating that its effects on histone acetylation are potentiated by caspases. In contrast, α-naphthyl tropolone upregulated p53 expression and phosphorylation of Akt and mTOR in a manner that was not rescued by caspase inhibition. The effects of tropolone were blocked by co-incubation with high levels of free extracellular iron but not by pre-loading with iron. Additionally, dose and time dependent reduction in ex vivo viability of cells from leukemia patients was observed. Taken together, we demonstrate that α-substituted tropolones upregulate DNA damage repair pathways leading to caspase-dependent apoptosis in malignant lymphocytes.

Abstract
Histone deacetylase 8 (HDAC8), a unique class I zinc-dependent HDAC, is an emerging target in cancer and other diseases. Its substrate repertoire extends beyond histones to many nonhistone proteins. Besides being a deacetylase, HDAC8 also mediates signaling via scaffolding functions. Aberrant expression or deregulated interactions with transcription factors are critical in HDAC8-dependent cancers. Many potent HDAC8-selective inhibitors with cellular activity and anticancer effects have been reported. We present HDAC8 as a druggable target and discuss inhibitors of different chemical scaffolds with cellular effects. Furthermore, we review HDAC8 activators that revert activity of mutant enzymes. Isotype-selective HDAC8 targeting in patients with HDAC8-relevant cancers is challenging, however, is promising to avoid adverse side effects as observed with pan-HDAC inhibitors.

Abstract
Inhibitors of histone deacetylases (HDACs) are nowadays part of the therapeutic arsenal mainly against cancers, with four compounds approved by the Food and Drug Administration. During the last five years, several groups have made continuous efforts to improve this class of compounds, designing more selective compounds or compounds with multiple capacities. After a survey of the HDAC biology and structures, this review summarizes the results of the chemists working in this field, and highlights when possible the behavior of the molecules inside their targets.

Abstract
The CSN complex plays a key role in various cellular pathways: through a metalloprotease activity of its Csn5 deneddylating enzyme, it regulates the activity of Cullin-RING ligases (CRLs). Indeed, Csn5 has been found amplified in many tumors, but, due to its pleiotropic effects, it is difficult to dissect its function and the involvement in cancer progression. Moreover, while growing evidences point to the neddylation function as a good target for drug development; specific inhibitors have not yet been developed for the CSN. Here, we propose the yeast Saccharomyces cerevisiae as a model system to screen libraries of small molecules as inhibitors of cullins deneddylation, taking advantage of the unique feature of this organism to survive without a functional CSN5 gene and to accumulate a fully neddylated cullin substrate. By combining molecular modeling and simple genetic tools, we were able to identify two small molecular fragments as selective inhibitors of Csn5 deneddylation function.

Abstract
Hodgkin's lymphoma (HL) is the most common malignant lymphoma in young adults in the western world. This disease is characterized by an overexpression of ADAM-10 with increased release of NKG2D ligands, involved in an impaired immune response against tumor cells. We designed and synthesized two new ADAM-10 selective inhibitors, 2 and 3 based on previously published ADAM-17 selective inhibitor 1. The most promising compound was the thiazolidine derivative 3, with nanomolar activity for ADAM-10, high selectivity over ADAM-17 and MMPs and good efficacy in reducing the shedding of NKG2D ligands (MIC-B and ULBP3) in three different HL cell lines at non-toxic doses. Molecular modeling studies were used to drive the design and X-ray crystallography studies were carried out to explain the selectivity of 3 for ADAM-10 over MMPs.

Abstract
Inhibitors of histone deacetylases (HDACi) hold considerable therapeutic promise as clinical anticancer therapies. However, currently known HDACi exhibit limited isoform specificity, off-target activity, and undesirable pharmaceutical properties. Thus, HDACi with new chemotypes are needed to overcome these limitations. Here, we identify a class of HDACi with a previously undescribed benzoylhydrazide scaffold that is selective for the class I HDACs. These compounds are competitive inhibitors with a fast-on/slow-off HDAC-binding mechanism. We show that the lead compound, UF010, inhibits cancer cell proliferation via class I HDAC inhibition. This causes global changes in protein acetylation and gene expression, resulting in activation of tumor suppressor pathways and concurrent inhibition of several oncogenic pathways. The isotype selectivity coupled with interesting biological activities in suppressing tumor cell proliferation support further preclinical development of the UF010 class of compounds for potential therapeutic applications.

Structural Basis of Metallo-β-Lactamase Inhibition by Captopril Stereoisomers. Antimicrob Agents Chemother 2015; 60:142-50.

Abstract
β-Lactams are the most successful antibacterials, but their effectiveness is threatened by resistance, most importantly by production of serine- and metallo-β-lactamases (MBLs). MBLs are of increasing concern because they catalyze the hydrolysis of almost all β-lactam antibiotics, including recent-generation carbapenems. Clinically useful serine-β-lactamase inhibitors have been developed, but such inhibitors are not available for MBLs. l-Captopril, which is used to treat hypertension via angiotensin-converting enzyme inhibition, has been reported to inhibit MBLs by chelating the active site zinc ions via its thiol(ate). We report systematic studies on B1 MBL inhibition by all four captopril stereoisomers. High-resolution crystal structures of three MBLs (IMP-1, BcII, and VIM-2) in complex with either the l- or d-captopril stereoisomer reveal correlations between the binding mode and inhibition potency. The results will be useful in the design of MBL inhibitors with the breadth of selectivity required for clinical application against carbapenem-resistant Enterobacteriaceae and other organisms causing MBL-mediated resistant infections.

Abstract
Metalloprotein inhibitors (MPi) are an important class of therapeutics for the treatment of a variety of diseases, including hypertension, cancer, and HIV/AIDS. However, despite their clinical success, there is an apprehension that MPi may be less selective than other small-molecule therapeutics and more prone to inhibit off-target metalloenzymes. We examined the issue of MPi specificity by investigating the selectivity of a variety of MPi against a representative panel of metalloenzymes in the presence of competing metalloproteins (metallothionein, myoglobin, carbonic anhydrase, and transferrin). Our findings reveal that a wide variety of MPi do not exhibit a decrease in inhibitory activity in the presence of large excesses of competing metalloproteins, suggesting that the competing proteins do not titrate the MPi away from its intended target. This study represents a rudimentary but important means to mimic the biological milieu, which contains other metalloproteins that could compete the MPi away from its target. The strategy used in this study may be a useful approach to examine the selectivity of other MPi in development.

Abstract
Zn(II) is used in nature as a biocatalyst in hundreds of enzymes, and the structure and dynamics of its catalytic activity are subjects of considerable interest. Many of the Zn(II)-based enzymes are classified as hydrolytic enzymes, in which the Lewis acidic Zn(II) center facilitates proton transfer(s) to a Lewis base, from proton donors such as water or thiol. This report presents the results of a quantum computational study quantifying the dynamic relationship between the zinc coordination number (CN), its coordination geometry, and the thermodynamic driving force behind these proton transfers originating from a charge-neutral methylthiol ligand. Specifically, density functional theory (DFT) and second-order perturbation theory (MP2) calculations have been performed on a series of [(imidazole)nZn-S(H)CH3](2+) and [(imidazole)nZn-SCH3](+) complexes with the CN varied from 1 to 6, n = 0-5. As the number of imidazole ligands coordinated to zinc increases, the S-H proton dissociation energy also increases, (i.e., -S(H)CH3 becomes less acidic), and the Zn-S bond energy decreases. Furthermore, at a constant CN, the S-H proton dissociation energy decreases as the S-Zn-(ImH)n angles increase about their equilibrium position. The zinc-coordinated thiol can become more or less acidic depending upon the position of the coordinated imidazole ligands. The bonding and thermodynamic relationships discussed may apply to larger systems that utilize the [(His)3Zn(II)-L] complex as the catalytic site, including carbonic anhydrase, carboxypeptidase, β-lactamase, the tumor necrosis factor-α-converting enzyme, and the matrix metalloproteinases.

Abstract
Highly substituted tropones are prepared from cycloheptatrienes derived from Rh-catalyzed intermolecular [5+2] cycloaddition of 3-acyloxy-1,4-enynes and propargylic alcohols. The intermolecular [5+2] cycloaddition is highly regioselective for a variety of propargylic alcohols. Elimination of the cycloaddition products afforded various substituted tropones.

Abstract
Tuberculosis (TB) continues to remain one of the most threatening diseases in the world. With the emergence of multi-drug resistant (MDR) and extensively drug resistant (XDR) strains, the need to develop new therapies is dire. The syntheses of a focused library of hydroxamates and hydroxamic acids is described, as well as anti-TB activity in the microplate alamar blue assay (MABA). A number of compounds exhibited good activity against Mtb, with notable compounds exhibiting MIC values in the range of 20-0.71 μM. This work suggests that both hydroxamates and their free acids may be incorporated into more complex scaffolds and serve as potential leads for the development of anti-TB agents.

Abstract
The emergence of antibiotic resistance places a sense of urgency on the development of alternative antibacterial strategies, of which targeting virulence factors has been regarded as a "second generation" antibiotic approach. In the case of Pseudomonas aeruginosa infections, a proteolytic virulence factor, LasB, is one such target. Unfortunately, we and others have not been successful in translating in vitro potency of LasB inhibitors to in vivo efficacy in an animal model. To overcome this obstacle, we now integrate in silico and in vitro identification of the mercaptoacetamide motif as an effective class of LasB inhibitors with full in vivo characterization of mercaptoacetamide prodrugs using Caenorhabditis elegans. We show that one of our mercaptoacetamide prodrugs has a good selectivity profile and high in vivo efficacy, and confirm that LasB is a promising target for the treatment of bacterial infections. In addition, our work highlights that the C. elegans infection model is a user-friendly and cost-effective translational tool for the development of anti-virulence compounds.

Abstract
Tropones and tropolones are an important class of seven-membered non-benzenoid aromatic compounds. They can be prepared directly by oxidation of seven-membered rings. They can also be derived from cyclization or cycloaddition of appropriate precursors followed by elimination or rearrangement. This review discusses the types of naturally occurring tropones and tropolones and outlines important methods developed for the synthesis of tropone and tropolone natural products.

Abstract
The new histone deacylases inhibitors (HDACi) were synthesized in the class of 5-membered cyclic hydroxamic acids (5-CHA), showing medium size CHA as a new Zn-binding group. New reaction sequence was proposed for the synthesis of 5-membered alkylidene-cyclic-hydroxamic acids starting from butyrolactone. Compound 10c showed low µM activity on HeLa cell extracts. From these results, cyclic hydroxamic acids will be further investigated to find more potent compounds.

Abstract
We previously identified 3-hydroxypyridine-2-thione (3HPT) as a novel zinc binding group for histone deacetylase (HDAC) inhibition. Early structure-activity relationship (SAR) studies led to various small molecules possessing selective inhibitory activity against HDAC6 or HDAC8 but devoid of HDAC1 inhibition. To delineate further the depth of the SAR of 3HPT-derived HDAC inhibitors (HDACi), we have extended the SAR studies to include the linker region and the surface recognition group to optimize the HDAC inhibition. The current efforts resulted in the identification of two lead compounds, 10d and 14e, with potent HDAC6 and HDAC8 activities that are inactive against HDAC1. These new HDACi possess anticancer activities against various cancer cell lines including Jurkat J.γ1 for which SAHA and the previously disclosed 3HPT-derived HDACi were inactive.
