We further supported the docking results with molecular dynamics simulations that confirmed the predicted binding mode. 5a also showed promising activity with an EC50 of 3.6 µM on neuroblastoma cells.

Additionally, we address significant challenges and outline future directions in this field. This perspective may provide guidance for the further development of HDAC11 inhibitors and their prospects in disease treatment.

The current study highlights the potential of HDAC11 downregulation in improving CAR-T cell therapy. The study will pave the way for further investigations focused on understanding and exploiting epigenetic mechanisms for immunotherapeutic outcomes.

Additionally, by integrating both established knowledge and recent research, the review seeks to contribute novel insights into the potential therapeutic applications of HDAC11 inhibitors. Overall, the scope of this review spans from fundamental research elucidating the complexities of HDAC11 biology to the potential of targeting HDAC11 in therapeutic interventions.

More interestingly, HDAC11 expression was elevated in ADSCs isolated from obese mice, and silencing of HDAC11 facilitated the spontaneous differentiation of ADSCs into mesoderm, which is the source of adipocytes. This also superficially and effectively demonstrates the exciting prospect of HDAC11 silencing in obesity research and treatment, as a valve for "energy saving and flow reduction".

Cytarabine-resistant acute myeloid leukemia (AML) is a common phenomenon, necessitating the search for new chemotherapeutics...Overall, the cell cycle inhibitor, PD0166285, is a potential chemotherapeutic drug for AML. These fundings contribute to a functional understanding of HDAC11 in AML.

In conclusion, this study found that HDAC11 expression is positively correlated with the overall survival rate of patients. HDAC11 can inhibit the invasion and proliferation of breast cancer cells to a certain extent and can be used as a good prognosis marker.

Mechanistically, HSP90 K754 is regulated by the cooperation of KAT8 and HDAC11 as the writer and eraser, respectively; SDCBP increases the Kbu level and stability of HSP90 by binding competitively to HDAC11. Furthermore, SDCBP blockade with the lead compound V020-9974 can target HSP90 K754 to overcome 5-FU resistance, constituting a potential therapeutic strategy.

Bone marrow-derived macrophages (BMDMs) isolated from C57BL/6 mice were pre-treated with HDAC6 (NexturastatA) or HDAC11 (FT895) inhibitors prior to polarizing them to M1 and M2 phenotypes...Transcriptomics and single-cell secretome analyses of macrophages indicate that HDAC6 and HDAC11 affects macrophage function in diametrically opposite directions. Therefore, our study underscores the importance of class-selective inhibition of HDACs over pan-HDAC inhibitors and the potential use of selective HDAC inhibitors as a therapeutic option to control macrophage phenotype in cancer and other conditions.

qPCR validation of transcriptomic RNA-seq data shows that SAHA treatment significantly reduced the LPS-induced mRNA levels of IL-1β, IL-6, DNMT1, and DNMT3A in BEAS-2B cells. Altogether, SAHA treatment alters the mitochondrial metabolism, epigenetic CpG methylation, and transcriptomic gene expression to inhibit LPS-induced inflammatory responses in lung epithelial cells, which may provide novel molecular targets to inhibit the inflammation component of lung carcinogenesis.

Our study revealed the blocking effect of HDAC1 and HDAC11 on the polarization of macrophages M1 in the microenvironment by inhibiting fatty acid metabolism.
