HDAC6 inhibitor ACY-1083 shows lung epithelial protective features in COPD

PLoS One 2022 Oct 12;17(10):e0266310.PMID:36223404DOI:10.1371/journal.pone.0266310.

Airway epithelial damage is a common feature in respiratory diseases such as COPD and has been suggested to drive inflammation and progression of disease. These features manifest as remodeling and destruction of lung epithelial characteristics including loss of small airways which contributes to chronic airway inflammation. Histone deacetylase 6 (HDAC6) has been shown to play a role in epithelial function and dysregulation, such as in cilia disassembly, epithelial to mesenchymal transition (EMT) and oxidative stress responses, and has been implicated in several diseases. We thus used ACY-1083, an inhibitor with high selectivity for HDAC6, and characterized its effects on epithelial function including epithelial disruption, cytokine production, remodeling, mucociliary clearance and cell characteristics. Primary lung epithelial air-liquid interface cultures from COPD patients were used and the impacts of TNF, TGF-β, cigarette smoke and bacterial challenges on epithelial function in the presence and absence of ACY-1083 were tested. Each challenge increased the permeability of the epithelial barrier whilst ACY-1083 blocked this effect and even decreased permeability in the absence of challenge. TNF was also shown to increase production of cytokines and mucins, with ACY-1083 reducing the effect. We observed that COPD-relevant stimulations created damage to the epithelium as seen on immunohistochemistry sections and that treatment with ACY-1083 maintained an intact cell layer and preserved mucociliary function. Interestingly, there was no direct effect on ciliary beat frequency or tight junction proteins indicating other mechanisms for the protected epithelium. In summary, ACY-1083 shows protection of the respiratory epithelium during COPD-relevant challenges which indicates a future potential to restore epithelial structure and function to halt disease progression in clinical practice.

HDAC6 inhibition effectively reverses chemotherapy-induced peripheral neuropathy

Pain 2017 Jun;158(6):1126-1137.PMID:28267067DOI:10.1097/j.pain.0000000000000893.

Chemotherapy-induced peripheral neuropathy is one of the most common dose-limiting side effects of cancer treatment. Currently, there is no Food and Drug Administration-approved treatment available. Histone deacetylase 6 (HDAC6) is a microtubule-associated deacetylase whose function includes regulation of α-tubulin-dependent intracellular mitochondrial transport. Here, we examined the effect of HDAC6 inhibition on established cisplatin-induced peripheral neuropathy. We used a novel HDAC6 inhibitor ACY-1083, which shows 260-fold selectivity towards HDAC6 vs other HDACs. Our results show that HDAC6 inhibition prevented cisplatin-induced mechanical allodynia, and also completely reversed already existing cisplatin-induced mechanical allodynia, spontaneous pain, and numbness. These findings were confirmed using the established HDAC6 inhibitor ACY-1215 (Ricolinostat), which is currently in clinical trials for cancer treatment. Mechanistically, treatment with the HDAC6 inhibitor increased α-tubulin acetylation in the peripheral nerve. In addition, HDAC6 inhibition restored the cisplatin-induced reduction in mitochondrial bioenergetics and mitochondrial content in the tibial nerve, indicating increased mitochondrial transport. At a later time point, dorsal root ganglion mitochondrial bioenergetics also improved. HDAC6 inhibition restored the loss of intraepidermal nerve fiber density in cisplatin-treated mice. Our results demonstrate that pharmacological inhibition of HDAC6 completely reverses all the hallmarks of established cisplatin-induced peripheral neuropathy by normalization of mitochondrial function in dorsal root ganglia and nerve, and restoration of intraepidermal innervation. These results are especially promising because one of the HDAC6 inhibitors tested here is currently in clinical trials as an add-on cancer therapy, highlighting the potential for a fast clinical translation of our findings.

Unusual zinc-binding mode of HDAC6-selective hydroxamate inhibitors

Proc Natl Acad Sci U S A 2017 Dec 19;114(51):13459-13464.PMID:29203661DOI:10.1073/pnas.1718823114.

Histone deacetylases (HDACs) regulate myriad cellular processes by catalyzing the hydrolysis of acetyl-l-lysine residues in histone and nonhistone proteins. The Zn2+-dependent class IIb enzyme HDAC6 regulates microtubule function by deacetylating α-tubulin, which suppresses microtubule dynamics and leads to cell cycle arrest and apoptosis. Accordingly, HDAC6 is a target for the development of selective inhibitors that might be useful in new therapeutic approaches for the treatment of cancer, neurodegenerative diseases, and other disorders. Here, we present high-resolution structures of catalytic domain 2 from Danio rerio HDAC6 (henceforth simply "HDAC6") complexed with compounds that selectively inhibit HDAC6 while maintaining nanomolar inhibitory potency: N-hydroxy-4-[(N(2-hydroxyethyl)-2-phenylacetamido)methyl)-benzamide)] (HPB), ACY-1215 (Ricolinostat), and ACY-1083. These structures reveal that an unusual monodentate Zn2+ coordination mode is exploited by sterically bulky HDAC6-selective phenylhydroxamate inhibitors. We additionally report the ultrahigh-resolution structure of the HDAC6-trichostatin A complex, which reveals two Zn2+-binding conformers for the inhibitor: a major conformer (70%) with canonical bidentate hydroxamate-Zn2+ coordination geometry and a minor conformer (30%) with monodentate hydroxamate-Zn2+ coordination geometry, reflecting a free energy difference of only 0.5 kcal/mol. The minor conformer is not visible in lower resolution structure determinations. Structural comparisons of HDAC6-inhibitor complexes with class I HDACs suggest active site features that contribute to the isozyme selectivity observed in biochemical assays.

Isoform 6-selective histone deacetylase inhibition reduces lesion size and brain swelling following traumatic brain injury and hemorrhagic shock

J Trauma Acute Care Surg 2019 Feb;86(2):232-239.PMID:30399139DOI:10.1097/TA.0000000000002119.

Background: Nonselective histone deacetylase (pan-HDAC) inhibitors, such as valproic acid (VPA), have demonstrated neuroprotective properties in trauma models. However, isoform-specific HDAC inhibitors may provide opportunity for more effective drug administration with fewer adverse effects. We investigated HDAC6 inhibition with ACY-1083 in an in vitro and an in vivo large animal model of injury. Methods: Mouse hippocampal cells were subjected to oxygen-glucose deprivation (0% O2, glucose-free and serum-free medium, 18 hours) and reoxygenation (21% O2, normal culture media, 4 hours) with/without VPA (4 mmol/L) or ACY-1083 (30 nmol/L, 300 nmol/L). Cell viability was measured by methylthiazolyl tetrazolium assay. Expression of hypoxia-inducible factor-1α, heat shock protein 70, and effectors in the phosphoinositide-3 kinase/mammalian target of rapamycin pathway were measured by Western blot analysis. Additionally, swine were subjected to combined traumatic brain injury and hemorrhagic shock and randomized to three treatment groups (n = 5/group): (i) normal saline (NS; 3× hemorrhage volume); (ii) NS + VPA (NS; 3× hemorrhage volume, VPA; 150 mg/kg), and (iii) NS + ACY-1083 (NS; 3× hemorrhage volume, ACY-1083; 30 mg/kg). After 6 hours, brain tissue was harvested to assess lesion size and brain swelling. Results: Significant improvement in cell viability was seen with both HDAC inhibitors in the in vitro study. ACY-1083 suppressed hypoxia-inducible factor-1α expression and up-regulated phosphorylated mammalian target of rapamycin and heat shock protein 70 in a dose-dependent manner. Lesion size and brain swelling in animals treated with pharmacologic agents (VPA and ACY-1083) were both smaller than in the NS group. No differences were observed between the VPA and ACY-1083 treatment groups. Conclusions: In conclusion, selective inhibition of HDAC6 is as neuroprotective as nonselective HDAC inhibition in large animal models of traumatic brain injury and hemorrhagic shock.

Histone deacetylase 6 inhibition improves survival in a swine model of lethal hemorrhage, polytrauma, and bacteremia

J Trauma Acute Care Surg 2020 Nov;89(5):932-939.PMID:32195993DOI:10.1097/TA.0000000000002677.

Background: Trauma is the leading cause of death for young Americans. Nonspecific histone deacetylase inhibitors, such as valproic acid, have been shown to improve survival in preclinical models of lethal trauma, hemorrhage, and sepsis. The doses needed to achieve a survival benefit are higher than Food and Drug Administration-approved doses, and the nonspecificity raises concerns about unintended adverse effects. The isoform-specific histone deacetylase 6 inhibitor, ACY-1083, has been found to be as efficacious as valproic acid in a rodent model of hemorrhagic shock. We hypothesized that ACY-1083 treatment would improve survival in a swine model of lethal hemorrhage, polytrauma, and bacteremia. Methods: Swine were subjected to 45% blood volume hemorrhage, brain injury, femur fracture, rectus crush, splenic and liver lacerations, and colon injury. After 1 hour of shock (mean arterial pressure, 30-35 mm Hg), animals were randomized to normal saline resuscitation (control) or normal saline plus ACY-1083 30 mg/kg treatment (n = 5/group). After 3 hours (simulating delayed evacuation), packed red blood cells and antibiotics were administered, the colon injury was repaired, and the abdomen was closed. Animals were then monitored for another 4 hours. Survival was assessed using Kaplan-Meier and log-rank test. Results: This combination of injuries was lethal. All animals became bacteremic, in addition to the severe hemorrhagic shock. Survival in the control group was 0%, and ACY-1083 treatment increased survival to 80% (p = 0.019). There was no difference in the brain lesion size between the groups. Conclusion: A single dose of ACY-1083 markedly improves survival in an otherwise lethal model of polytrauma, hemorrhagic shock, and bacteremia.
