Article Abstract

A novel series of ethyl ketone based HDACs 1, 2, and 3 selective inhibitors have been identified with good enzymatic and cellular activity and high selectivity over HDACs 6 and 8. These inhibitors contain a spirobicyclic group in the amide region. Compound 13 stands out as a lead due to its good potency, high selectivity, and reasonable rat and dog PK. Compounds 33 and 34 show good potency and rat PK profiles as well.

TP53-agnostic lethality through combined pan-HDAC and CDK inhibition in acute myeloid leukemia.

Tumor protein 53 (TP53)-mutated acute myeloid leukemia (AML) is characterized by poor outcomes and the quick development of treatment resistance. Here, we report that simultaneous inhibition of cyclin-dependent kinases (CDKs) and histone deacetylases (HDACs) with dinaciclib and CAY10603, respectively, eliminates the therapeutic response gap between TP53-mutant and TP53 wild-type AML. Biochemical profiling showed that CAY10603 is not only HDAC6-selective but also exhibits pan-HDAC activity similar to suberoylanilide hydroxamic acid, enabling dual targeting of transcriptional and cell cycle pathways.

Antiretroviral therapy (ART) has dramatically improved the clinical prognosis for people with HIV and prevents HIV transmission. However, ART does not cure HIV infection because of a persistent, latent viral reservoir in long-lived cells such as central memory CD4+ T (TCM) cells. Eliminating or preventing reservoir formation will require a better understanding of HIV-1 latency establishment.

Unregulated epigenetic modifications, including histone acetylation/deacetylation mediated by histone acetyltransferases (HATs) and histone deacetylases (HDACs), contribute to cancer progression. HDACs, often overexpressed in cancer, downregulate tumor suppressor genes, making them crucial targets for treatment. This work aimed to develop non-hydroxamate benzoic acid-based HDAC inhibitors (HDACi) with comparable effect to the currently four FDA-approved HDACi, which are known for their poor solubility, poor distribution, and significant side effects.

Class IIa HDACs Are Important Signal Transducers with Unclear Enzymatic Activities.

Class IIa histone deacetylases (HDACs) are pleiotropic regulators of various differentiation pathways and adaptive responses. They form complexes with other co-repressors and can bind to DNA by interacting with selected transcription factors, with members of the Myocyte Enhancer Factor-2 (MEF2) family being the best characterized. A notable feature of class IIa HDACs is the substitution of tyrosine for histidine in the catalytic site, which has occurred over the course of evolution and has a profound effect on the efficiency of catalysis against acetyl-lysine.

Epigenetic modulators of the histone deacetylase (HDAC) family control key biological processes and are frequently dysregulated in cancer. There is superior activity of HDAC inhibitors (HDACi) in patients with myeloproliferative neoplasms (MPNs) that carry the Janus kinase-2 point mutant JAK2. This constitutively active tyrosine kinase activates signal-transducer-and-activator-of-transcription (STAT) transcription factors to promote cell proliferation and inflammatory processes.
