Development of HDAC Inhibitors Exhibiting Therapeutic Potential in T-Cell Prolymphocytic Leukemia

Open access

Abstract

Epigenetic targeting has emerged as an efficacious therapy for hematological cancers.The rare and incurable T-cell prolymphocytic leukemia (T-PLL) is known for its aggressive clinical course.Current epigenetic agents such as histone deacetylase (HDAC) inhibitors are increasingly used for targeted therapy.Through a structure-activity relationship (SAR) study, we developed an HDAC6 inhibitor KT-531, which exhibited higher potency in T-PLL compared to other hematological cancers.KT-531 displayed strong HDAC6 inhibitory potency and selectivity, on-target biological activity, and a safe therapeutic window in nontransformed cell lines.In primary T-PLL patient cells, where HDAC6 was found to be overexpressed, KT-531 exhibited strong biological responses, and safety in healthy donor samples.Notably, combination studies in T-PLL patient samples demonstrated KT-531 synergizes with approved cancer drugs, bendamustine, idasanutlin, and venetoclax.Our work suggests HDAC inhibition in T-PLL could afford sufficient therapeutic windows to achieve durable remission either as standalone or in combination with targeted drugs.

  • Installing a hydroxamate on any molecule with limited optimization is strongly biased for generating pan-HDACi, among other possible interactions with metalloproteins.

    “Despite their exquisite potency against HDACs, installing a hydroxamate on any molecule with limited optimization is strongly biased for generating pan-HDACi, among many other possible interactions with metalloproteins (aminopeptidases, carbonic anhydrase, etc.) that can be chelated in a similar manner [38].”

    From Medicinal chemistry advances in targeting class I histone deacetylases (2023) · cites this paper as [38]

    The Introduction (page not provided) says that HDAC inhibitors generally exhibit broad-spectrum activity, and the Results show that changes to a hydroxamic-acid-containing compound alter its HDAC selectivity. The paper does not establish that adding a hydroxamate to any molecule with limited optimization tends to produce a pan-HDAC inhibitor, or that such compounds interact with aminopeptidases, carbonic anhydrase, or other metalloproteins.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
