Abstract
Human sirtuin 5 (SIRT5) participates in a variety of metabolic disorder-associated diseases, including cancer. Inhibition of SIRT5 has been confirmed to provide a new strategy for treatment of related diseases. Previously, we discovered a pyrimidine skeleton inhibitor XIV, which showed low micromolar inhibitory activity against SIRT5. Herein, we utilized the scaffold-hopping strategy to design and synthesize a series of 2,4,6- trisubstituted triazine derivatives. The SAR analysis led to the discovery of several new SIRT5 inhibitors with low micromolar inhibition levels. The most potent compounds 10 (IC50 = 5.38 µM), and 14 (IC50 = 4.07 µM) were further confirmed to be the substrate-competitive SIRT5 inhibitors through enzyme kinetic assays, which is consistent with the molecular docking analyses. Fluorescence-based thermal shift assays proved that these compounds may stabilize SIRT5 by binding withprotein.. In addition, compounds 10 and 14 were also revealed to have moderate selectivity to SIRT5 over SIRT1-3. This study will aid further efforts to develop highly potent and selective SIRT5 inhibitors for the treatment of cancer and other related diseases.

Abstract
Histones undergo a plethora of post-translational modifications (PTMs) that regulate nucleosome and chromatin dynamics and thus dictate cell fate. Several evidences suggest that the accumulation of epigenetic alterations is one of the key driving forces triggering aberrant cellular proliferation, invasion, metastasis and chemoresistance pathways. Recently a novel class of histone "non-enzymatic covalent modifications" (NECMs), correlating epigenome landscape and metabolic rewiring, have been described. These modifications are tightly related to cell metabolic fitness and are able to impair chromatin architecture. During metabolic reprogramming, the high metabolic flux induces the accumulation of metabolic intermediate and/or by-products able to react with histone tails altering epigenome homeostasis. The accumulation of histone NECMs is a damaging condition that cancer cells counteracts by overexpressing peculiar "eraser" enzymes capable of removing these modifications preserving histones architecture. In this review we explored the well-established NECMs, emphasizing the role of their corresponding eraser enzymes. Additionally, we provide a parterre of drugs aiming to target those eraser enzymes with the intent to propose novel routes of personalized medicine based on the identification of epi-biomarkers which might be selectively targeted for therapy.

Abstract
Sepsis-associated acute kidney injury (AKI) is a serious clinical problem without effective drugs. Inhibition of sirtuin 5 (SIRT5) has been confirmed to protect against AKI, suggesting that SIRT5 inhibitors might be a promising therapeutic approach for AKI. Herein, structural optimization was performed on our previous compound 1 (IC50 = 3.0 μM), and a series of 2,4,5-trisubstituted pyrimidine derivatives have been synthesized. The structure-activity relationship (SAR) analysis led to the discovery of three nanomolar level SIRT5 inhibitors, of which the most potent compound 58 (IC50 = 310 nM) was demonstrated to be a substrate-competitive and selective inhibitor. Importantly, 58 significantly alleviated kidney dysfunction and pathological injury in both lipopolysaccharide (LPS)- and cecal ligation/perforation (CLP)-induced septic AKI mice. Further studies revealed that 58 regulated protein succinylation and the release of proinflammatory cytokines in the kidneys of septic AKI mice. Collectively, these results highlighted that targeting SIRT5 has a therapeutic potential against septic AKI.

Abstract
SIRT5 has been implicated in various physiological processes and human diseases, including cancer. Development of new highly potent, selective SIRT5 inhibitors is still needed to investigate disease-related mechanisms and therapeutic potentials. We here report new ε-N-thioglutaryllysine derivatives, which were designed according to SIRT5-catalysed deacylation reactions. These ε-N-thioglutaryllysine derivatives displayed potent SIRT5 inhibition, of which the potential photo-crosslinking derivative 8 manifested most potent inhibition with an IC50 value of 120 nM to SIRT5, and low inhibition to SIRT1-3 and SIRT6. The enzyme kinetic assays revealed that the ε-N-thioglutaryllysine derivatives inhibit SIRT5 by lysine-substrate competitive manner. Co-crystallographic analyses demonstrated that 8 binds to occupy the lysine-substate binding site by making hydrogen-bonding and electrostatic interactions with SIRT5-specific residues, and is likely positioned to react with NAD+ and form stable thio-intermediates. Compound 8 was observed to have low photo-crosslinking probability to SIRT5, possibly due to inappropriate position of the diazirine group as observed in SIRT5:8 crystal structure. This study provides useful information for developing drug-like inhibitors and cross-linking chemical probes for SIRT5-related studies.

Abstract
Sirtiun 5 (SIRT5) is a NAD+-dependent protein lysine deacylase. It is emerging as a promising target for the development of drugs to treat cancer and metabolism-related diseases. In this study, we screened 5000 compounds and identified a hit compound 14 bearing a pyrazolone functional group as a novel SIRT5-selective inhibitor. Structure-based optimization of 14 resulted in compound 47 with an IC50 value of 0.21 ± 0.02 μM and a 100-fold improved potency. Compound 47 showed substantial selectivity for SIRT5 over SIRT1-3 and SIRT6. Biochemical studies suggest that 47 does not occupy the NAD + -binding pocket and acts as a substrate-competitive inhibitor. The identified potent and selective SIRT5 inhibitors allow further studies as research tools and therapeutic agents.

Abstract
Sirtuins are NAD+-dependent deac(et)ylases with different subcellular localization. The sirtuins’ family is composed of seven members, named SIRT-1 to SIRT-7. Their substrates include histones and also an increasing number of different proteins. Sirtuins regulate a wide range of different processes, ranging from transcription to metabolism to genome stability. Thus, their dysregulation has been related to the pathogenesis of different diseases. In this review, we discussed the pharmacological approaches based on sirtuins’ modulators (both inhibitors and activators) that have been attempted in in vitro and/or in in vivo experimental settings, to highlight the therapeutic potential of targeting one/more specific sirtuin isoform(s) in cancer, neurodegenerative disorders and type 2 diabetes. Extensive research has already been performed to identify SIRT-1 and -2 modulators, while compounds targeting the other sirtuins have been less studied so far. Beside sections dedicated to each sirtuin, in the present review we also included sections dedicated to pan-sirtuins’ and to parasitic sirtuins’ modulators. A special focus is dedicated to the sirtuins’ modulators identified by the use of virtual screening.

Abstract
Sirtiun 5 (SIRT5) is a NAD+-dependent protein lysine deacylase primarily located in mitochondria. SIRT5 displays an affinity for negatively charged acyl groups and mainly catalyzes lysine deglutarylation, desuccinylation, and demalonylation while possessing weak deacetylase activity. SIRT5 substrates play crucial roles in metabolism and reactive oxygen species (ROS) detoxification, and SIRT5 activity is protective in neuronal and cardiac physiology. Moreover, SIRT5 exhibits a dichotomous role in cancer, acting as context-dependent tumor promoter or suppressor. Given its multifaceted activity, SIRT5 is a promising target in the design of activators or inhibitors that might act as therapeutics in many pathologies, including cancer, cardiovascular disorders, and neurodegeneration. To date, few cellular-active peptide-based SIRT5 inhibitors (SIRT5i) have been described, and potent and selective small-molecule SIRT5i have yet to be discovered. In this perspective, we provide an outline of SIRT5's roles in different biological settings and describe SIRT5 modulators in terms of their mode of action, pharmacological activity, and structure-activity relationships.

Abstract
Human sirtuin 5 (SIRT5) plays pivotal roles in metabolic pathways and other biological processes, and is involved in several human diseases including cancer. Development of new potent and selective SIRT5 inhibitors is currently desirable to provide potential therapeutics for related diseases. Herein, we report a series of new 3-thioureidopropanoic acid derivatives, which were designed to mimic the binding features of SIRT5 glutaryl-lysine substrates. Structure-activity relationship studies revealed several compounds with low micromolar inhibitory activities to SIRT5. Computational and biochemical studies indicated that these compounds exhibited competitive SIRT5 inhibition with respect to the glutaryl-lysine substrate rather than nicotinamide adenine dinucleotide cofactor. Moreover, they showed high selectivity for SIRT5 over SIRT1-3 and 6 and could stabilize SIRT5 proteins as revealed by thermal shift analyses. This work provides an effective substrate-mimicking strategy for future inhibitor design, and offers new inhibitors to investigate their therapeutic potentials in SIRT5-associated disease models.

Abstract
Recent evidence has prompted the notion of gut-microbial signatures as an indirect marker of aging and aging-associated decline in humans. However, the underlying host-symbiont molecular interactions contributing to these signatures remain poorly understood. In this study, we address this gap using cheminformatic analyses to elucidate potential gut microbial metabolites that may perturb the longevity-associated NAD+ metabolic network. In silico ADMET, KEGG interaction analysis, molecular docking, molecular dynamics simulation, and molecular mechanics calculation predict a large number of safe and bioavailable microbial metabolites to be direct and/or indirect activators of NAD+-dependent sirtuin proteins. Our simulation results suggest dihydropteroate, phenylpyruvic acid, indole-3-propionic acid, phenyllactic acid, all-trans-retinoic acid, and multiple deoxy-, methyl-, and cyclic nucleotides from intestinal microbiota as the best-performing regulators of NAD+ metabolism. Retracing these molecules to their source microorganisms also suggest commensal Escherichia, Bacteroides, Bifidobacteria, and Lactobacilli to be associated with the highest number of pro-longevity metabolites. These findings from our early-stage study, therefore, provide an informatics-based context for previous evidence in the area and grant novel insights for future clinical investigation intersecting anti-aging drug discovery, probiotics, and gut microbial signatures.

Jiang Y, Zheng W. Cyclic Tripeptide-based Potent and Selective Human SIRT5 Inhibitors. Med Chem 2020; 16:358-367. [PMID: 31161996 DOI: 10.2174/1573406415666190603101937] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2018] [Revised: 04/29/2019] [Accepted: 04/29/2019] [Indexed: 12/18/2022]
Abstract
BACKGROUND SIRT5 is one of the seven members (SIRT1-7) of the mammalian sirtuin family of protein acyl-lysine deacylase enzymes. In recent years, important regulatory roles of SIRT5 in (patho)physiological conditions (e.g. metabolism and cancer) have been increasingly demonstrated. For a better biological understanding and therapeutic exploitation of the SIRT5- catalyzed deacylation reaction, more effort on identifying potent and selective SIRT5 inhibitors beyond those currently known would be rewarding. OBJECTIVE In the current study, we would like to see if it would be possible to develop potent and selective SIRT5 inhibitory lead compounds with a novel structural scaffold than those of the currently known potent and selective SIRT5 inhibitors. METHODS In the current study, six N-terminus-to-side chain cyclic tripeptides (i.e. 8-13) each harboring the thiourea-type catalytic mechanism-based SIRT5 inhibitory warhead Nε-carboxyethylthiocarbamoyl- lysine as the central residue were designed, synthesized by the Nα-9- fluorenylmethoxycarbonyl (Fmoc) chemistry-based solid phase peptide synthesis (SPPS) on the Rink amide 4-methylbenzhydrylamine (MBHA) resin, purified by the semi-preparative reversedphase high performance liquid chromatography (RP-HPLC), characterized by the high-resolution mass spectrometry (HRMS); and were evaluated by the in vitro sirtuin inhibition assay and the in vitro proteolysis assay. RESULTS Among the cyclic tripeptides 8-13, we found that 10 exhibited a potent (IC50 ~2.2 μM) and selective (≥60-fold over the SIRT1/2/3/6-catalyzed deacylation reactions) inhibition against the SIRT5-catalyzed desuccinylation reaction. Moreover, 10 was found to exhibit a ~42.3-fold stronger SIRT5 inhibition and a greater proteolytic stability than its linear counterpart 14. CONCLUSION With a novel and modular structural scaffold as compared with those of all the currently reported potent and selective SIRT5 inhibitors, 10 could be also a useful and feasible lead compound for the quest for superior SIRT5 inhibitors as potential chemical/pharmacological probes of SIRT5 and therapeutics for human diseases in which SIRT5 desuccinylase activity is upregulated.

Identification of the subtype-selective Sirt5 inhibitor balsalazide through systematic SAR analysis and rationalization via theoretical investigations. Eur J Med Chem 2020; 206:112676. [PMID: 32858418 DOI: 10.1016/j.ejmech.2020.112676] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 07/17/2020] [Accepted: 07/18/2020] [Indexed: 12/30/2022]
Abstract
We report here an extensive structure-activity relationship study of balsalazide, which was previously identified in a high-throughput screening as an inhibitor of Sirt5. To get a closer understanding why this compound is able to inhibit Sirt5, we initially performed docking experiments comparing the binding mode of a succinylated peptide as the natural substrate and balsalazide with Sirt5 in the presence of NAD+. Based on the evidence gathered here, we designed and synthesized 13 analogues of balsalazide, in which single functional groups were either deleted or slightly altered to investigate which of them are mandatory for high inhibitory activity. Our study confirms that balsalazide with all its given functional groups is an inhibitor of Sirt5 in the low micromolar concentration range and structural modifications presented in this study did not increase potency. While changes on the N-aroyl-β-alanine side chain eliminated potency, the introduction of a truncated salicylic acid part minimally altered potency. Calculations of the associated reaction paths showed that the inhibition potency is very likely dominated by the stability of the inhibitor-enzyme complex and not the type of inhibition (covalent vs. non-covalent). Further in-vitro characterization in a trypsin coupled assay determined that the tested inhibitors showed no competition towards NAD+ or the synthetic substrate analogue ZKsA. In addition, investigations for subtype selectivity revealed that balsalazide is a subtype-selective Sirt5 inhibitor, and our initial SAR and docking studies pave the way for further optimization.

Abstract
Human sirtuin 2 (SIRT2), a member of the sirtuin family, has been considered as a promising drug target in cancer, neurodegenerative diseases, type II diabetes, and bacterial infections. Thus, SIRT2 inhibitors have been involved in effective treatment strategies for related diseases. Using previously established fluorescence-based assays for SIRT2 activity tests, the authors screened their in-house database and identified a compound, 4-(5-((3-(quinolin-5-yl)ureido)methyl)furan-2-yl)benzoic acid (20), which displayed 63 ± 5% and 35 ± 3% inhibition against SIRT2 at 100 μM and 10 μM, respectively. The structure-activity relationship (SAR) analyses of a series of synthesized (5-phenylfuran-2-yl)methanamine derivatives led to the identification of a potent compound 25 with an IC50 value of 2.47 μM, which is more potent than AGK2 (IC50 = 17.75 μM). Meanwhile, 25 likely possesses better water solubility (cLogP = 1.63 and cLogS = -3.63). Finally, the molecular docking analyses indicated that 25 fitted well with the induced hydrophobic pocket of SIRT2.

Abstract
Sirtuins are NAD+-dependent protein deacylases/ADP-ribosyltransferases that have emerged as candidate targets for new therapeutics to treat metabolic disorders and other diseases, including cancer. The sirtuin SIRT5 resides primarily in the mitochondrial matrix and catalyzes the removal of negatively charged lysine acyl modifications; succinyl, malonyl, and glutaryl groups. Evidence has now accumulated to document the roles of SIRT5 as a significant regulator of cellular homeostasis, in a context- and cell-type specific manner, as has been observed previously for other sirtuin family members. SIRT5 regulates protein substrates involved in glycolysis, the TCA cycle, fatty acid oxidation, electron transport chain, ketone body formation, nitrogenous waste management, and ROS detoxification, among other processes. SIRT5 plays pivotal roles in cardiac physiology and stress responses and is involved in the regulation of numerous aspects of myocardial energy metabolism. SIRT5 is implicated in neoplasia, as both a tumor promoter and suppressor in a context-specific manner, and may serve a protective function in the setting of neurodegenerative disorders. Here, we review the current understanding of functional impacts of SIRT5 on its metabolic targets, and its molecular functions in both normal and pathological conditions. Finally, we will discuss the potential utility of SIRT5 as a drug target and also summarize the current status, progress, and challenges in developing small molecule compounds to modulate SIRT5 activity with high potency and specificity.

Abstract
Sirtuins are protein deacylases that regulate metabolism and stress responses and are implicated in aging-related diseases. Modulators of the human sirtuins Sirt1-7 are sought as chemical tools and potential therapeutics, e.g., for cancer. Selective and potent inhibitors are available for Sirt2, but selective inhibitors for Sirt5 with Ki values in the low nanomolar range are lacking. We synthesized and screened 3-arylthiosuccinylated and 3-benzylthiosuccinylated peptide derivatives yielding Sirt5 inhibitors with low-nanomolar Ki values. A biotinylated derivative with this scaffold represents an affinity probe for human Sirt5 that is able to selectively extract this enzyme out of complex biological samples like cell lysates. Crystal structures of Sirt5/inhibitor complexes reveal that the compounds bind in an unexpected manner to the active site of Sirt5.

Abstract
Sirtuins are nicotinamide adenine dinucleotide (NAD+)-dependent class III histone deacetylases, which have been linked to the pathogenesis of numerous diseases, including HIV, metabolic disorders, neurodegeneration and cancer. Docking of the virtual pan-African natural products library (p-ANAPL), followed by in vitro testing, resulted in the identification of two inhibitors of sirtuin 1, 2 and 3 (sirt1–3). Two bichalcones, known as rhuschalcone IV (8) and an analogue of rhuschalcone I (9), previously isolated from the medicinal plant Rhus pyroides, were shown to be active in the in vitro assay. The rhuschalcone I analogue (9) showed the best activity against sirt1, with an IC50 value of 40.8 µM. Based on the docking experiments, suggestions for improving the biological activities of the newly identified hit compounds have been provided.
