Abstract
Porous structure, biocompatibility and biodegradability, large surface area, and drug-loading ability are some remarkable properties of zeolite structure, making it a great possible option for bone tissue engineering. Herein, we evaluated the potential application of the ZSM-5 scaffold encapsulated GEN with high porosity structure and significant antibacterial properties. The space holder process has been employed as a new fabrication method with interconnected pores and suitable mechanical properties. In this study, for the first time, ZSM-5 scaffolds with GEN drug-loading were fabricated with the space holder method. The results showed excellent open porosity in the range of 70-78% for different GEN concentrations and appropriate mechanical properties. Apatite formation on the scaffold surface was determined with Simulation body fluid (SBF), and a new bone-like apatite layer shaping on all samples confirmed the in vitro bioactivity of ZSM-5-GEN scaffolds. Also, antibacterial properties were investigated against both gram-positive and gram-negative bacteria. The incorporation of various amounts of GEN increased the inhibition zone from 24 to 28 (for E. coli) and 26 to 37 (for S. aureus). In the culture with MG63 cells, great cell viability and high cell proliferation after 7 days of culture were determined.

Abstract
The sirtuin enzymes are a family of lysine deacylases that regulate gene transcription and metabolism. Sirtuin 5 (SIRT5) hydrolyzes malonyl, succinyl, and glutaryl ϵ-N-carboxyacyllysine posttranslational modifications and has recently emerged as a vulnerability in certain cancers. However, chemical probes to illuminate its potential as a pharmacological target have been lacking. Here we report the harnessing of aryl fluorosulfate-based electrophiles as an avenue to furnish covalent inhibitors that target SIRT5. Alkyne-tagged affinity-labeling agents recognize and capture overexpressed SIRT5 in cultured HEK293T cells and can label SIRT5 in the hearts of mice upon intravenous injection of the compound. This work demonstrates the utility of aryl fluorosulfate electrophiles for targeting of SIRT5 and suggests this as a means for the development of potential covalent drug candidates. It is our hope that these results will serve as inspiration for future studies investigating SIRT5 and general sirtuin biology in the mitochondria.

Abstract
Despite the significant advancement in bone tissue engineering, it is still challenging to find a desired scaffold with suitable mechanical and biological properties, efficient bone formation in the defect area, and antibacterial resistivity. In this study, the zeolite (ZSM-5) scaffold was developed using the space holder method, and a novel vancomycin-loaded alginate coating was developed on it to promote their characteristics. Our results demonstrated the importance of alginate coating on the microstructure, mechanical, and cellular properties of the ZSM-5 scaffold. For instance, a three-fold increase in the compressive strength of coated scaffolds was observed compared to the uncoated ZSM-5. After the incorporation of vancomycin into the alginate coating, the scaffold revealed significant antibacterial activity against Staphylococcus aureus (S. aureus). The inhibition zone increased to 35 mm. Resets also demonstrated 74 ± 2.5% porosity, 4.3 ± 0.07 MPa strength in compressive conditions, acceptable cellular properties (72.3 ± 0.2 (%control) cell viability) after 7 days, good cell attachment, and calcium deposition. Overall, the results revealed that this scaffold could be a great candidate for bone tissue engineering.

Abstract
Sirtuin 5 (SIRT5) is a protein lysine deacylase enzyme that regulates diverse biology by hydrolyzing ϵ-N-carboxyacyllysine posttranslational modifications in the cell. Inhibition of SIRT5 has been linked to potential treatment of several cancers but potent compounds with activity in cells have been lacking. Here we developed mechanism-based inhibitors that incorporate isosteres of a carboxylic acid residue that is important for high-affinity binding to the enzyme active site. By masking of the tetrazole moiety of the most potent candidate from our initial SAR study, we achieved potent and cytoselective growth inhibition for the treatment of SIRT5-dependent leukemic cancer cell lines in culture. Thus, we provide an efficient, cellularly active small molecule that targets SIRT5, which can help elucidate its function and potential as a future drug target. This work shows that masked isosteres of carboxylic acids are viable chemical motifs for the development of inhibitors that target mitochondrial enzymes, which may have applications beyond the sirtuin field.

Abstract
Abstract
Standard of care for AML includes chemotherapy and stem cell transplant, with 5-year survival rates <30%. We sought to identify genes critical to AML cells, irrespective of mutational status, and performed an shRNA screen targeting 1,287 genes on 12 AML patient samples. This screen identified Sirtuin 5 (SIRT5) as a top candidate. SIRT5 is the only known enzyme with desuccinylase, demalonylase, and/or deglutarylase activity and we are the first to report the dependence of AML cells on SIRT5. Next, we stably transduced a panel of AML cell lines with doxycycline (dox)-inducible shSIRT5 (dox-shSIRT5). SIRT5 knockdown (KD) strongly inhibited cell growth, colony formation and increased apoptosis in 15/22 lines (SIRT5-dependent), while 7/22 lines were SIRT5-independent. SIRT5 dependence did not correlate with AML-related mutations nor basal SIRT5 expression. SIRT5 KD in primary AML samples (N=25) revealed a therapeutic window (~50% reduction), with no effect in CB samples (N=5). We examined the requirement of SIRT5 in vivo using three mouse models of leukemia. In a xenograft model with AML cell lines, SIRT5 KD indefinitely prolonged survival of mice injected with SIRT5-dependent cells with no sign of leukemia. Bone marrow transplant with transduced (MLL-AF9 or BCR-ABL1) SIRT5 null cells showed reduced leukemia cell burden and splenomegaly, and significantly prolonged survival. FLT3-ITD-driven disease was also blunted by the absence of SIRT5 in a genetic knockout mouse model. Mechanically, SIRT5 KD profoundly reduced oxidative phosphorylation (OXPHOS) and glycolysis. Additionally, SIRT5 KD increased mitochondrial superoxide selectively in annexin V-negative, SIRT5-dependent cells. Concomitant, ectopic expression of SOD2 abrogated the increase in superoxide, rescued cells from apoptosis, and rescued the colony formation deficit. Untargeted metabolomics revealed RNA charging and alanine and serine metabolism as top metabolic pathways regulated by SIRT5, with glutaminase (GLS) and α-ketoglutarate identified as potential upstream regulators. Metabolic tracing experiments with [13C5,15N2]-glutamine confirmed disrupted glutamine metabolism in SIRT5-dependent cells. Together, these results indicate that SIRT5 is required to regulate glutamine flux to sustain redox homeostasis and/or anabolism. NRD167, a novel SIRT5 inhibitor, was used to target SIRT5 in AML. NRD167 reduced cell proliferation, induced apoptosis, and reduced OXPHOS in SIRT5-dependent but not SIRT5-independent cells. NRD167 inhibited colony formation from AML patient samples, but not in CB samples. An AML patient-derived xenograft model trended toward prolonged survival following ex vivo treatment with NRD167. Our data suggest that the majority of AML samples are dependent on SIRT5 and that inhibition preferentially targets AML cells, implicating SIRT5 as a therapy target in AML.

Abstract
Sirtuin 3 (SIRT3) is the major protein lysine deacetylase in the mitochondria. This hydrolase regulates a wide range of metabolically involved enzymes and has been considered as a potential drug target in certain cancers. Investigation of pharmacological intervention has been challenging due to a lack of potent and selective inhibitors of SIRT3. Here, we developed a strategy for selective inhibition of SIRT3 in cells, over its structurally similar isozymes that localize primarily to the nucleus (SIRT1) and the cytosol (SIRT2). This was achieved by directing the inhibitors to the mitochondria through incorporation of mitochondria-targeting peptide sequences into the inhibitor structures. Our inhibitors exhibited excellent mitochondrial localization in HeLa cells as indicated by fluorophore-conjugated versions, and target engagement was demonstrated by a cellular thermal shift assay of SIRT3 using western blotting. The acetylation state of documented SIRT3 target MnSOD was shown to be increased in cells with little effect on known targets of SIRT1 and SIRT2, showing that our lead compound exhibits selectivity for SIRT3 in cells. We expect that the developed inhibitor will now enable a more detailed investigation of SIRT3 as a potential drug target and help shed further light on the diverse biology regulated by this enzyme.

Abstract
Sirtuin 2 (SIRT2) is a protein deacylase enzyme that removes acetyl groups and longer chain acyl groups from post-translationally modified lysine residues. It affects diverse biological functions in the cell and has been considered a drug target in relation to both neurodegenerative diseases and cancer. Therefore, access to well-characterized and robust tool compounds is essential for the continued investigation of the complex functions of this enzyme. Here, we report a collection of chemical probes that are potent, selective, stable in serum, water-soluble, and inhibit SIRT2-mediated deacetylation and demyristoylation in cells. Compared to the current landscape of SIRT2 inhibitors, this is a unique ensemble of features built into a single compound. We expect the developed chemotypes to find broad application in the interrogation of SIRT2 functions in both healthy and diseased cells, and to provide a foundation for the development of future therapeutics. Sirtuin 2 (SIRT2) is a protein deacylase enzyme that removes acetyl groups and longer chain acyl groups from post-translationally modified lysine residues. Here, we developed small peptide-based inhibitors of its activity in living cells in culture.![]()

Abstract
The sirtuin enzymes are potential drug targets for intervention in a series of diseases. Efforts to inhibit enzymes of this class with thioamide- and thiourea-containing, substrate-mimicking entities have produced a number of high-affinity binders. However, less attention has been dedicated to the investigation of the stability of these inhibitors under various conditions. Here, we provide evidence of an unprecedented degree of cleavage of short-chain ε-N-thioacyllysine modifications meant to target these sirtuins and further provide insights into the serum stability of compounds containing both thioamides and thioureas. Our study questions the utility short-chain thioamide-based inhibitors of sirtuins for drug development and points to monoalkylated thiourea-based chemotypes as being more stable in human serum.

Abstract
We discovered that the survival and growth of many primary acute myeloid leukemia (AML) samples and cell lines, but not normal CD34+ cells, are dependent on SIRT5, a lysine deacylase implicated in regulating multiple metabolic pathways. Dependence on SIRT5 is genotype-agnostic and extends to RAS- and p53-mutated AML. Results were comparable between SIRT5 knockdown and SIRT5 inhibition using NRD167, a potent and selective SIRT5 inhibitor. Apoptosis induced by SIRT5 disruption is preceded by reductions in oxidative phosphorylation and glutamine utilization, and an increase in mitochondrial superoxide that is attenuated by ectopic superoxide dismutase 2. These data indicate that SIRT5 controls and coordinates several key metabolic pathways in AML and implicate SIRT5 as a vulnerability in AML.

Abstract
Sirtuins, a group of NAD+-dependent deacylases, have emerged as the key connection between NAD+ metabolism and aging. This class of enzymes hydrolyzes a range of ε- N-acyllysine PTMs, and determining the repertoire of catalyzed deacylation reactions is of high importance to fully elucidate the roles of a given sirtuin. Here we have identified and produced two potential sirtuins from the probiotic bacterium Lactobacillus acidophilus NCFM. Screening more than 80 different substrates, covering 26 acyl groups on five peptide scaffolds, demonstrated that one of the investigated proteins, Sir2La, is a bona fide NAD+-dependent sirtuin, catalyzing hydrolysis of acetyl-, propionyl-, and butyryllysine. Further substantiating the identity of Sir2La as a sirtuin, known sirtuin inhibitors, nicotinamide and suramin, as well as a thioacetyllysine compound inhibit the deacylase activity in a concentration-dependent manner. On the basis of steady-state kinetics, Sir2La showed a slight preference for propionyllysine (Kpro) over acetyllysine (Kac). For nonfluorogenic peptide substrates, the preference is driven by a remarkably low KM (280 nM vs 700 nM, for Kpro and Kac, respectively), whereas kcat was similar (21 × 10-3 s-1). Moreover, while NAD+ is a prerequisite for Sir2La-mediated deacylation, Sir2La has a very high KM for NAD+ compared to the expected levels of the dinucleotide in L. acidophilus. Sir2La is the first sirtuin from Lactobacillales and of the Gram-positive bacterial subclass of sirtuins to be functionally characterized. The ability to hydrolyze propionyl- and butyryllysine emphasizes the relevance of further exploring the role of other short-chain acyl moieties as PTMs.

Abstract
Lysine residues across the proteome are modified by posttranslational modifications (PTMs) that significantly enhance the structural and functional diversity of proteins. For lysine, the most abundant PTM is ɛ-N-acetyllysine (Kac), which plays numerous roles in regulation of important cellular functions, such as gene expression (epigenetic effects) and metabolism. A family of enzymes, namely histone deacetylases (HDACs), removes these PTMs. A subset of these enzymes, the sirtuins (SIRTs), represent class III HDAC and, unlike the rest of the family, these hydrolases are NAD+-dependent. Although initially described as deacetylases, alternative deacylase functions for sirtuins have been reported, which expands the potential cellular roles of this class of enzymes. Currently, sirtuins are investigated as therapeutic targets for the treatment of diseases that span from cancers to neurodegenerative disorders. In the present book chapter, we review and discuss the current literature on novel ɛ-N-acyllysine PTMs, targeted by sirtuins, as well as mechanism-based sirtuin inhibitors inspired by their substrates.

Abstract
The sirtuin enzymes are important regulatory deacylases in a variety of biochemical contexts and may therefore be potential therapeutic targets through either activation or inhibition by small molecules. Here, we describe the discovery of the most potent inhibitor of sirtuin 5 (SIRT5) reported to date. We provide rationalization of the mode of binding by solving co-crystal structures of selected inhibitors in complex with both human and zebrafish SIRT5, which provide insight for future optimization of inhibitors with more "drug-like" properties. Importantly, enzyme kinetic evaluation revealed a slow, tight-binding mechanism of inhibition, which is unprecedented for SIRT5. This is important information when applying inhibitors to probe mechanisms in biology.

Abstract
In small laboratory species, steroid measures can be obtained more frequently and less invasively from urine than blood. Insofar as urinary levels reflect systemic levels, they could provide advantages particularly for measurement of glucocorticoids, whose blood levels react rapidly to handling and stress. In Experiment 1, urinary samples were collected from male mice every second hour over a 14:10 h light:dark cycle. Samples were analyzed via enzyme immunoassay for corticosterone, testosterone, and creatinine. Corticosterone had peak concentrations 1 h after light offset and a trough 1 h after light onset. Testosterone showed peak concentrations 5-7 h after light onset and lowest concentrations during the dark phase of the cycle. Creatinine showed some variation over the light-dark cycle, but steroid measures showed similar trends with and without adjustment for creatinine. In Experiment 2, mice were stressed via an injection at times close to the determined peak and trough levels of corticosterone. In urinary samples taken 90 min after injection, corticosterone was significantly higher in injected animals at both times relative to levels in control animals, but testosterone was unaffected by injection stress. In Experiment 3, serum and urine samples were collected from mice every sixth hour across the diurnal cycle. Corticosterone peaked in urine and serum immediately after light offset, and urinary measures predicted those in serum. These data indicate that urinary corticosterone reflects systemic levels in mice, document circadian variation in urinary testosterone, and indicate that circadian variation in creatinine is minimal, but potentially relevant in stressed animals.

Abstract
Patients with coronary artery disease (CAD) and concomitant left bundle branch block (LBBB) have increased cardiovascular mortality rates in comparison with those with CAD but without LBBB. In patients with LBBB, therefore, the delineation of the presence and severity of CAD may be helpful in providing prognostic information. In this cross-sectional study 219 patients with LBBB and suspected CAD that underwent coronary angiography, assessed for having CAD and left ventricular (LV) dysfunction. CAD was present in 124 (56.3%) patients and left ventricular ejection fraction <50% was seen in 147 (67.1%) patients. Advanced age (p=0.001), male gender (p=0.027, OR=1.94), history of chest pain (p=0.015, OR=2.08) and LVEF <50% (p=0.026, OR=3.04) were predictors of CAD and older age (p=0.004), male gender (p=0.017, OR=2.11), history of diabetes mellitus (p=0.043, OR=1.45) and angiographically documented CAD (p=0.001, OR=3.41) were predictors of LV dysfunction.
