AI Article Synopsis
- * The review aims to highlight drug design approaches that can lead to the creation of better HDAC inhibitors by analyzing existing literature and clinical trials from 2021-2022 related to HDAC isoforms and inhibitor strategies.
- * Future drug discovery efforts will likely focus on achieving isoform-selectivity, understanding the 3D structures of HDAC complexes, and exploring the biological functions of HDACs to improve the efficiency of discovering new inhibitors.
Article Abstract
Background: Histone deacetylases (HDACs) are one of the essential epigenetic targets in cancer treatment. These enzymes play key roles in post-translation modification (PTM) and gene expression, and consequently, their inhibitors are about to find their place in pharmacotherapy. Most of the currently approved HDAC inhibitors (HDACIs) are wide-spectrum with poor clinical outcomes and numerous side effects. Therefore, new generations of HDAC-based chemotherapeutics with better clinical outcomes are emerging, e.g., isoform-selective inhibitors, multitargeted HDACIs, as well as HDAC degraders.
Aim: The review intended to introduce drug design approaches which were used for designing novel agents which can be beneficial in the process of finding new and more effective HDACI-based therapeutics.
Methods: PubMed and other databases were searched for literature regarding the structure-function of HDAC isoforms, and strategies used to design HDAC inhibitors. Also, all clinical trials available from the ClinicalTrials site for years 2021-2022 were investigated.
Key Findings: It is expected that the future of drug discovery projects in HDAC field will concentrate mostly on issues such as isoform-selectivity, multitargeted HDAC inhibitors and HDAC degraders. Deeper knowledge of the 3D structure of HDACs complexed with inhibitors and extensive delineation of biological roles of HDACs are needed for efficient investigations leading to the discovery of novel potent inhibitors.
Significance: Histone deacetylases (HDACs) are one of the important epigenetic targets in cancer treatment drug discovery. Comprehending the structure of HDAC isoforms along with applied drug design strategies can inspire new ideas.

Protein lactylation is a new form of post-translational modification that has recently been proposed. Lactoyl groups, derived mainly from the glycolytic product lactate, have been linked to protein lactylation in brain tissue, which has been shown to correlate with increased neuronal excitability. Ischemic stroke may promote neuronal glycolysis, leading to lactate accumulation in brain tissue.

Histone deacetylase 3 (HDAC3) is a well-established target for cancer therapy. Herein, we developed as a novel HDAC3 inhibitor, which exhibited high HDAC3 inhibitory activity (IC = 42 nM, SI > 161) and displayed potent antiproliferative activity against four cancer cells and further demonstrated excellent antimigratory, anti-invasive, and antiwound healing activities. Further studies revealed that induced a dose-dependent increase in Ac-H3 expression and promoted the degradation of PD-L1.

Due to the lack of effective therapeutic approach, glioblastoma (GBM) remains one of the most malignant brain tumour. By in vitro investigations on primary GBM stem cells, we highlighted one of the underlying mechanisms of drug resistance to alkylating agents, the DNA damage responses. Here, flow cytometric analysis and viability and repopulation assays were used to assess the long-term cytotoxic effect induced by the administration of a fourth-generation platinum prodrug, the (OC-6-44)-acetatodiamminedichlorido(2-(2-propynyl)octanoato) platinum(IV) named Pt(IV)Ac-POA, in comparison to the most widely used Cisplatin.
