Abstract

This review classifies drug‐design strategies successfully implemented in the development of histone deacetylase (HDAC) inhibitors, which have many applications including cancer treatment. Our focus is on especially demanded selective HDAC inhibitors and their structure‐activity relationships in relation to corresponding protein structures. The main part of the paper is divided into six subsections each narrating how optimization of one of six structural features can influence inhibitor selectivity. It starts with the impact of the zinc binding group on selectivity, continues with the optimization of the linker placed in the substrate binding tunnel as well as the adjustment of the cap group interacting with the surface of the protein, and ends with the addition of groups targeting class‐specific sub‐pockets: the side‐pocket‐, lower‐pocket‐ and foot‐pocket‐targeting groups. The review is rounded off with a conclusion and an outlook on the future of HDAC inhibitor design.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • HDAC8 is unique within the HDAC family; while structurally most similar to other class I HDAC catalytic domains, it operates in a monomeric fashion.

    “HDAC8 is unique within the HDAC family, and while it is structurally the most similar to other class I HDAC catalytic domains it operates in a monomeric fashion [7].”
  • HDACi selectivity is traditionally gained from optimizing the cap group due to conservation of residues around the interior of the catalytic tunnel and increased variation around the surface residues of each HDAC.

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.
