Abstract
A new toluidine blue-myristic acid photosensitizer derivate (TBOMyr) was investigated as a design molecule to bind simultaneously to cucurbit[7]uril (CB[7]) and human serum albumin (HSA) with the aim of constructing a biosupramolecular assembly. Molecular docking and dynamics calculations revealed the main supramolecular and bio-molecular interactions of TBOMyr with the macrocycle or the protein, respectively. The addition of the negatively charged myristic acid-like tail resulted in a unique conformation of the CB[7] complex where the phenothiazine core was included in the cavity of CB[7], leaving the fatty acid portion free to interact with the protein. A favorable ternary interaction between TBOMyr, CB[7] and HSA was suggested by the calculations, and an experimental binding affinity in the order of 105 M-1 was determined for the TBOMyr@CB[7] complex with HSA. The new TBOMyr derivative could find applications in photodynamic therapy benefiting from the biosupramolecular interactions as a transport system.

Novel Multitarget Hydroxamic Acids with a Natural Origin CAP Group against Alzheimer's Disease: Synthesis, Docking and Biological Evaluation. Pharmaceutics 2021; 13:pharmaceutics13111893. [PMID: 34834312 PMCID: PMC8623418 DOI: 10.3390/pharmaceutics13111893] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 10/30/2021] [Accepted: 11/04/2021] [Indexed: 02/05/2023] Open
Abstract
Hydroxamic acids are one of the most promising and actively studied classes of chemical compounds in medicinal chemistry. In this study, we describe the directed synthesis and effects of HDAC6 inhibitors. Fragments of adamantane and natural terpenes camphane and fenchane, combined with linkers of various nature with an amide group, were used as the CAP groups. Accordingly, 11 original target compounds were developed, synthesized, and exposed to in vitro and in vivo biological evaluations, including in silico methods. In silico studies showed that all synthesized compounds were drug-like and could penetrate through the blood-brain barrier. According to the in vitro testing, hydroxamic acids 15 and 25, which effectively inhibited HDAC6 and exhibited anti-aggregation properties against β-amyloid peptides, were chosen as the most promising substances to study their neuroprotective activities in vivo. All in vivo studies were performed using 5xFAD transgenic mice simulating Alzheimer's disease. In these animals, the Novel Object Recognition and Morris Water Maze Test showed that the formation of hippocampus-dependent long-term episodic and spatial memory was deteriorated. Hydroxamic acid 15 restored normal memory functions to the level observed in control wild-type animals. Notably, this effect was precisely associated with the ability to restore lost cognitive functions, but not with the effect on motor and exploratory activities or on the level of anxiety in animals. Conclusively, hydroxamic acid 15 containing an adamantane fragment linked by an amide bond to a hydrocarbon linker is a possible potential multitarget agent against Alzheimer's disease.

Abstract
Histone deacetylase enzymes (HDACs) are potential targets for the treatment of cancer and other diseases, but it is challenging to design isoform-selective agents. In this work, we created new analogs of two established but non-selective HDAC inhibitors. We decorated the central linker chains of the molecules with specifically positioned fluorine atoms in order to control the molecular conformations. The fluorinated analogs were screened against a panel of 11 HDAC isoforms, and minor differences in isoform selectivity patterns were observed.

Abstract
The emergence of photoredox catalysis has enabled the discovery of mild and efficient conditions for the generation of a variety of radical reaction platforms. Herein is disclosed the development of a conjugate addition reaction of non-activated alkyl bromides to Michael acceptors under visible-light photoredox catalysis. Optimization of the reaction was achieved using high-throughput experimentation (HTE) tools to enable the identification of mild, general and practical reaction conditions. A diverse set of alkyl bromides was successfully added to cyclic or acyclic α,β-unsaturated esters and amides. The features of this transformation allowed also access to a key intermediate of Vorinostat®, an HDAC inhibitor used to fight cancer and HIV.

Abstract
We designed and synthesized carbamates of the clinically-approved HDAC (histone deacetylase) inhibitor vorinostat (suberoylanilide hydroxamic acid, SAHA) in order to validate our previously-proposed hypothesis that these carbamates might serve as prodrugs for hydroxamic acid containing HDAC inhibitors. Biochemical assays proved our new compounds to be potent inhibitors of histone deacetylases in vitro, and they also showed antiproliferative effects in leukemic cells. These results, as well as stability analysis led to the suggestion that the intact carbamates are inhibitors of histone deacetylases themselves, representing a new zinc-binding warhead in HDAC inhibitor design. This suggestion was further supported by the synthesis and evaluation of a carbamate derivative of the HDAC6-selective inhibitor bufexamac.

Abstract
We herein present broadly useful, readily available and nonintegral hydroxylamine linkers for the routine solid-phase synthesis of hydroxamic acids. The developed protocols enable the efficient synthesis and release of a wide range of hydroxamic acids from various resins, relying on high control and flexibility with respect to reagents and synthetic processes. A trityl-based hydroxylamine linker was used to synthesize a library of peptide hydroxamic acids. The inhibitory effects of the compounds were examined for seven HDAC enzyme subtypes using a chemiluminescence-based assay.

Abstract
Histone deacetylase (HDAC) proteins have emerged as targets for anti-cancer therapeutics, with several inhibitors used in the clinic, including suberoylanilide hydroxamic acid (SAHA, vorinostat). Because SAHA and many other inhibitors target all or most of the 11 human HDAC proteins, the creation of selective inhibitors has been studied intensely. Recently, inhibitors selective for HDAC1 and HDAC2 were reported where selectivity was attributed to interactions between substituents on the metal binding moiety of the inhibitor and residues in the 14-Å internal cavity of the HDAC enzyme structure. Based on this earlier work, we synthesized and tested SAHA analogs with substituents on the hydroxamic acid metal binding moiety. The N-substituted SAHA analogs displayed reduced potency and solubility, but greater selectivity, compared to SAHA. Docking studies suggested that the N-substituent accesses the 14-Å internal cavity to impart preferential inhibition of HDAC1. These studies with N-substituted SAHA analogs are consistent with the strategy exploiting the 14-Å internal cavity of HDAC proteins to create HDAC1/2 selective inhibitors.

Abstract
Strategies to ameliorate the flaws of current chemotherapeutic agents, while maintaining potent anticancer activity, are of particular interest. Agents which can modulate multiple targets may have superior utility and fewer side effects than current single-target drugs. To explore the prospect in cancer therapy of a bivalent agent that combines two complementary chemo-active groups within a single molecular architecture, we have synthesized dual-acting histone deacetylase and topoisomerase II inhibitors. These dual-acting agents are derived from suberoylanilide hydroxamic acid (SAHA) and anthracycline daunorubicin, prototypical histone deacetylase (HDAC) and topoisomerase II (Topo II) inhibitors, respectively. We report herein that these agents present the signatures of inhibition of HDAC and Topo II in both cell-free and whole-cell assays. Moreover, these agents potently inhibit the proliferation of representative cancer cell lines.

Abstract
Inhibition of human histone deacetylases (HDACs) has emerged as a novel concept in the chemotherapeutic treatment of cancer. Two chemical entities, SAHA (ZOLINZA, Merck) and romidepsin (Istodax, Celgene) have been recently approved by the FDA as first-in-class drugs against cutaneous T-cell lymphoma. Clinical use of these drugs revealed several side effects including gastro-intestinal symptoms, fatigue, thrombocytopenia, thrombosis. Romidepsin is associated with an yet unresolved cardiotoxicity issue. A general hypothesis for the diminishment of unwanted adverse effects and an improved therapeutical window suggests the development of more isotype selective inhibitors. In this study the first time HDAC inhibitors with perfluorinated spacers between the zinc chelating moiety and the aromatic capping group were synthesized and tested against representatives of HDAC classes I, IIa and IIb. Competitive binding assays and a combined approach by using blind docking and molecular dynamics support binding of the perfluorinated analogs of SAHA to the active site of the HDAC-like amidohydrolase from Bordetella/Alcaligenes and presumably also to human HDACs. In contrast to the alkyl spacer of SAHA and derivatives, the perfluorinated alkyl spacer seems to contribute to or facilitate the induction of selectivity for class II, particularly class IIa, HDACs even though the overall potency of the perfluorinated SAHA analogs in this study against human HDACs remained still rather moderate in the micromolar range.

Abstract
OBJECTIVES A small pool of long-lived memory CD4 T cells harboring the retroviral genome is one main obstacle to HIV eradication. We tested the impact of the gold compound, auranofin, on phenotype and viability of CD4 T cells in vitro, and on persistence of lentiviral reservoir cells in vivo. DESIGN In-vitro and in-vivo study. The pro-differentiating effect of auranofin was investigated in human primary CD4 T cells, and its capacity to deplete the viral DNA (vDNA) reservoir was tested in a pilot study involving six SIVmac251-infected macaques with viral loads stably suppressed by antiretroviral therapy (ART) (tenofovir/emtricitabine/raltegravir). The study was then amplified by intensifying ART using darunavir/r and including controls under intensified ART alone. All therapies were eventually suspended and viro-immunological parameters were monitored over time. METHODS Cell subpopulations were quantitated by flow cytometry following proper hematological analyses. Viral load and cell-associated vDNA were quantitated by Taqman real-time PCR. RESULTS In naïve, central memory and transitional memory CD4 T cells, auranofin induced both phenotype changes and cell death which were more pronounced in the memory compartment. In the pilot study in vivo, auranofin transiently decreased the cell-associated vDNA reservoir in peripheral blood. When ART was intensified, a sustained decrease in vDNA was observed only in auranofin-treated monkeys but not in controls treated with intensified ART alone. After therapy suspension, only monkeys that had received auranofin showed a deferred and subsequently blunted viral load rebound. CONCLUSION These findings represent a first step towards a remission of primate lentiviral infections.

Abstract
Four novel series of cinnamyl-containing histone deacetylase (HDAC) inhibitors 1-4 are described, containing hydroxamate (1 and 3) or 2-aminoanilide (2 and 4) derivatives. When screened against class I (maize HD1-B and human HDAC1) and class II (maize HD1-A and human HDAC4) HDACs, most hydroxamates and 2-aminoanilides displayed potent and selective inhibition toward class I enzymes. Immunoblotting analyses performed in U937 leukemia cells generally revealed high acetyl-H3 and low acetyl-α-tubulin levels. Exceptions are compounds 3 f-i, 3 m-o, and 4 k, which showed higher tubulin acetylation than SAHA. In U937 cells, cell-cycle blockade in either the G₂/M or G₁/S phase was observed with 1-4. Five hydroxamates (compounds 1 h-l) effected a two- to greater than threefold greater percent apoptosis than SAHA, and in the CD11c cytodifferentiation test some 2-aminoanilides belonging to both series 2 and 4 were more active than MS-275. The highest-scoring derivatives in terms of apoptosis (1 k, 1 l) or cytodifferentiation (2 c, 4 n) also showed antiproliferative activity in U937 cells, thus representing valuable tools for study in other cancer contexts.

Abstract
A novel class of KAT modulators (long chain alkylidenemalonates, LoCAMs) has been identified. Variations of the alkyl chain length can change the activity profile from inhibition of both KAT3A/KAT2B (as derivative 2a) to the peculiar profile of pentadecylidenemalonate 1b, the first activator/inhibitor of histone acetyltransferases. Together with the powerful apoptotic effect (particularly notable if considering that anacardic acid and other KAT inhibitors are not cell permeable) appoint them as valuable biological tools to understand the mechanisms of lysine acetyltransferases.

Abstract
PURPOSE Histone Deacetylase Inhibitors (DI) ameliorates dystrophic muscle regeneration restoring muscular strength in the mdx mouse model of Duchenne muscular dystrophy (DMD). The further development of these compounds as drugs for DMD treatment is currently hampered by the lack of knowledge about DIs effect in large dystrophic animal models and that of suitable biomarkers to monitor their efficacy. EXPERIMENTAL DESIGN In this study we applied proteomic analysis to identify differentially expressed proteins present in plasma samples from mdx mice treated with the Suberoylanilide hydroxamic acid (SAHA) and relative normal controls (WT). RESULTS Several differentially expressed proteins were identified between untreated wild type and mdx mice. Among these, fibrinogen, epidermal growth factor 2 receptor, major urinary protein and glutathione peroxidase 3 (GPX3) were constitutively up-regulated in mdx, while complement C3, complement C6, gelsolin, leukaemia inhibitory factor receptor (LIFr), and alpha 2 macroglobulin were down-regulated compared to WT mice. SAHA determined the normalization of LIFr and GPX3 protein level while apoliprotein E was de novo up-regulated in comparison to vehicle-treated mdx mice. CONCLUSIONS AND CLINICAL RELEVANCE Collectively, these data unravel potential serological disease biomarkers of mdx that could be useful to monitor muscular dystrophy response to DI treatment.

Abstract
(Aryloxopropenyl)pyrrolyl hydroxamates were recently reported by us as first examples of class II-selective HDAC inhibitors and can be useful tools to probe the biology of such enzymes. Molecular modelling and 3-D QSAR studies have been performed on a series of 25 (aryloxopropenyl)pyrrolyl hydroxamates to gain insights about their activity and selectivity against both maize HD1-B and HD1-A, two enzymes homologous of mammalian class I and class II HDACs, respectively. The studies have been accomplished by calculating alignment-independent descriptors (GRIND descriptors) using the ALMOND software. Highly descriptive and predictive 3-D QSAR models were obtained using either class I or class II inhibitory activity displaying r(2)/q(2) values of 0.96/0.81 and 0.98/0.85 for HD1-B and HD1-A, respectively. A deeper inspection revealed that in general a bent molecular shape structure is a prerequisite for HD1-A-selective inhibitory activity, while straight shape molecular skeleton leads to selective HD1-B compounds. The same conclusions could be achieved by molecular docking studies of the most selective inhibitors.

Abstract
We have designed and synthesized a series of structurally novel hydroxamic acid-based histone deacetylase (HDAC) inhibitors characterized by a zinc chelating head group attached directly to a thiazole ring. The thiazole ring connects to a piperazine spacer, which is capped with a sulfonamide group. These novel molecules potently inhibit an HDAC enzyme mixture derived from HeLa cervical carcinoma cells and show potent antiproliferative activity against the breast cancer cell line MCF7.

Abstract
Among fungal pathogens such as Candida albicans, acquired drug resistance has not been associated with plasmids or other transferable elements, but it is thought to involve primarily mutations and genetic or epigenetic phenomena. This prompted us to test some histone deacetylase inhibitors (HDACi) from our library, in combination with fluconazole, against C. albicans strains in vitro. Among the tested compounds, the two chloro-containing uracil-hydroxamates 1c and 1d showed a strong reduction of the MIC values on Candida strains that show the trailing growth effect. In this assay, 1c,d were more potent than SAHA, a well-known HDAC inhibitor, in reducing the Candida growth. More interestingly, 1c,d as well as SAHA were able to inhibit the fluconazole-induced resistance induction in Candida cultures.

Abstract
The novel aroyl-pyrrolyl hydroxyamides 4 a-a' are analogues of the lead compound 3-(1-methyl-4-phenylacetyl-1H-pyrrol-2-yl)-N-hydroxy-2-propenamide (2) and are active as HDAC inhibitors. The benzene ring of 2 was substituted with a wide range of electron-donating and electron-withdrawing groups, and the effect was evaluated on three HDACs from maize, namely HD2, HD1-B (a class I HDAC), and HD1-A (a class II HDAC). Inhibition studies show that the benzene 3' and, to a lesser extent, 4' positions of 2 were the most suitable for the introduction of substituents, with the 3'-chloro (in 4 b) and the 3'-methyl (in 4 k) derivatives being the most potent compounds, reaching the same activity as SAHA. Inhibition data for 4 b,k against mouse HDAC1 were consistent with those observed in the maize enzyme. The substituent insertion on the benzene ring of 2 (compounds 4 a-a') abated the slight (3-fold) selectivity for class II HDACs displayed by 2. Compound 4 b showed interesting, dose-dependent antiproliferative and cytodifferentiation properties against human acute promyelocytic leukemia HL-60 cells.

Among these compounds, 5b was found to be as potent as SAHA. Kinetic enzyme assays and molecular modeling suggested that the mercaptoacetamide moiety of 5b interacts with the zinc in the active site of HDACs and removes a water molecule from the reactive site of the deacetylation.
