Histone Deacetylase 6 (HDAC 6) inhibitors Understanding

Histone Deacetylase 6 (HDAC 6) inhibitors: Overview

Development of isoform-selective histone deacetylase (HDAC) inhibitors is important in elucidating the function of individual HDAC enzymes and their potential as therapeutic agents. Among the eleven zinc-dependent HDACs in humans, HDAC6 is structurally and functionally unique. Histone deacetylase 6 (HDAC6) is unique among the eleven zinc-dependent HDACs in humans. HDAC6 is located in the cytoplasm, and it has two catalytic domains and an ubiquitin-binding domain at the C-terminal region. HDAC6 plays a key role in the regulation of microtubule dynamics including cell migration and cell–cell interactions. The reversible acetylation of Hsp90, a substrate of HDAC6, modulates its chaperone activity and, accordingly, the stability of survival and antiapoptotic factors, including epidermal growth factor receptor (EGFR), protein kinase AKT, proto-oncogene C-RAF, survivin, and other factors. HDAC6, through its ubiquitin-binding activity and interaction with other partner proteins, plays a role in the degradation of misfolded proteins by binding polyubiquitinated proteins and delivering them to the dynein and motor proteins for transport into aggresomes which are degraded by lysosomes. Thus, HDAC6 has multiple biological functions through deacetylase-dependent and -independent mechanisms modulating many cellular pathways relevant to normal and tumor cell growth, migration, and death. HDAC6 is an attractive target for potential cancer treatment.

Histone Deacetylase 6 (HDAC 6) inhibitors Emerging Drugs Chapters

This segment of the Histone Deacetylase 6 (HDAC 6) inhibitors report encloses its detailed analysis of various drugs in different stages of clinical development, including phase II, I, preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Histone Deacetylase 6 (HDAC 6) inhibitors Emerging Drugs

• Ricolinostat: Regenacy Pharmaceuticals

Ricolinostat, an oral, selective histone deacetylase 6 (HDAC6) inhibitor, has the potential to become the first-in-class treatment that reverses the underlying peripheral neuropathy, thereby relieving pain, numbness, motor function loss, and all other symptoms of the disease. Ricolinostat restores nerve function by inhibiting HDAC6, which reestablishes the transport function of microtubules in the axon of the nerve cell. Multiple preclinical animal models have demonstrated that HDAC6 inhibition restores nerve fibers, leading to the reversal of both pain and numbness in peripheral and other neuropathies, such as chemotherapy-induced peripheral neuropathy and Charcot-Marie-Tooth disease Type 2, an orphan-designated disease. It is currently being evaluated in Phase II clinical trial to treat Diabetic peripheral neuropathy.

• CKD 506: Chong Kun Dang Pharmaceuticals

CKD 504 is HDAC6 protein inhibitor currently being developed and investigated in Phase II stage of development for the treatment of Rheumatoid Arthritis. The drug reduces inflammation by inhibiting histone deacetylase 6 (HDAC6) thus affecting inflammatory diseases and enhancing the T-cell function to boost immune response.

• Resminostat: 4SC

Resminostat is an orally administered histone deacetylase (HDAC) inhibitor that potentially represents a novel therapy for a broad spectrum of oncology indications, both in monotherapy and particularly in combination with other anti-cancer drugs. In preclinical models, resminostat has shown selectivity for class I, IIB and IV HDAC enzymes with a particular specificity toward inhibiting the protein HDAC6, which is active in metastasis. Resminostat has the potential to provide significant benefit to patients by inhibiting tumor progression and metastasis, inducing tumor regression and enhancing the body’s own immune response to cancer. In July 2020 4SC initiated a Phase II Study to Evaluate Efficacy, Safety and Pharmacokinetics of 4SC-201 and the Treatment Combination of Sorafenib Plus 4SC-201 in Patients With Hepatocellular Carcinoma Exhibiting Progressive Disease Under Sorafenib Treatment.

• KA2507: Karus Therapeutics

KA2507 is a highly-selective and potent inhibitor of the tubulin deacetylase, HDAC6. Selective inhibition of this enzyme confers a cancer immunotherapeutic response by regulating immune checkpoint markers within the tumor microenvironment. HDAC6 has also emerged as a potentially important therapeutic target due to its overexpression in solid tumors and its role in specific mutant-harboring cancers. Karus considers KA2507 to hold broad therapeutic potential for the treatment of solid tumors, as both a single agent and in combination with other drugs. The drug is currently being evaluated in Phase I stage of development.
