We have developed an efficient method for synthesizing candidate histone deacetylase (HDAC) inhibitors in 96-well plates, which are used directly in high-throughput screening. We selected building blocks having hydrazide, aldehyde and hydroxamic acid functionalities. The hydrazides were coupled with different aldehydes in DMSO. The resulting products have the previously identified 'cap/linker/biasing element' structure known to favor inhibition of HDACs. These compounds were assayed without further purification. HDAC8-selective inhibitors were discovered from this novel collection of compounds.

Histone deacetylase inhibition with givinostat: a multi-targeted mode of action with the potential to halt the pathological cascade of Duchenne muscular dystrophy.

Muscle repair and regeneration are complex processes. In Duchenne muscular dystrophy (DMD), these processes are disrupted by the loss of functional dystrophin, a key part of the transmembrane dystrophin-associated glycoprotein complex that stabilizes myofibers, indirectly leading to progressive muscle wasting, subsequent loss of ambulation, respiratory and cardiac insufficiency, and premature death. As part of the DMD pathology, histone deacetylase (HDAC) activity is constitutively increased, leading to epigenetic changes and inhibition of muscle regeneration factors, chronic inflammation, fibrosis, and adipogenesis.

Background: Numerous pathogenic variants causing human oocyte maturation arrest have been reported on the primate-specific TUBB8 gene. The main etiology is the dramatic reduction of tubulin α/β dimer, but still large numbers of variants remain unexplained.
Methods: Using microinjection mRNA and genome engineering to reintroduce the conserved pathogenic missense variants into oocytes or in generating TUBB8 variant knock-in mouse models, we investigated that the human deleterious variants alter microtubule nucleation and spindle assembly during meiosis.

Diabetic nephropathy (DN) is a serious complication of diabetes, and inflammation plays a crucial role. Sirtuin 2 (SIRT2), a NAD+-dependent deacetylase, which is involved in the regulation of cell metabolism, proliferation and longevity through deacetylation. Our previous research showed a positive correlation between urinary SIRT2 levels and renal injury markers in DN patients.

Purpose: This study seeks to investigate the fundamental molecular processes through which histone deacetylase 9 (HDAC9) governs the proliferation of glomerular mesangial cells in the context of immunoglobulin A nephropathy (IgAN) and to identify novel targets for clinical research on IgAN.
Methods: Data from high-throughput RNA sequencing for IgAN were procured from the Gene Expression Omnibus database to assess the expression profiles and clinical diagnostic significance of histone deacetylase family proteins (HDACs). Blood samples from 20 IgAN patients were employed in RT-qPCR analysis, and the spearman linear regression method was utilized to analyze the clinical correlation.

Recent therapeutic strategies have highlighted the potential of β-hydroxybutyrate (BHB) and α-ketoglutarate (α-KG) as effective anticancer agents, particularly for colon cancer. These metabolites can modulate cellular metabolism and induce epigenetic changes, inhibiting tumor growth. Nonetheless, certain cancer cells may utilize ketone bodies, like BHB as nutrient sources under hypoxic conditions, potentially reducing treatment efficacy.
