Abstract

The broad study of histone deacetylases in chemistry, biology and medicine relies on tool compounds to derive mechanistic insights. A phylogenetic analysis of Class I and II HDACs as targets of a comprehensive, structurally diverse panel of inhibitors revealed unexpected isoform selectivity even among compounds widely perceived as non-selective. The synthesis and study of a focused library of cinnamic hydroxamates allowed the identification of a first non-selective HDAC inhibitor. These data will guide a more informed use of HDAC inhibitors as chemical probes and therapeutic agents.

  • Benzamide-containing HDACi possess greater isoform selectivity profiles, targeting specifically only the class I subgroup of HDACs.

    “They have also been demonstrated to possess greater isoform selectivity profiles, targeting specifically only the class I subgroup of HDACs (6-10, 26, 38, 39).”

    The Results identify MS-275, CI-994 and MGDC-0103 as benzamide-based inhibitors; the Discussion reports extraordinary selectivity of this inhibitor type for HDAC1, HDAC2 and HDAC3 over the other enzymes discussed. But the claim’s “only” is stronger than the evidence: the Comparative Study says HDAC10 and HDAC11 could not be assayed, so the paper does not establish exclusivity across all HDAC isoforms. No page numbers were provided in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • SAHA and TSA selectivity profiles extended well beyond HDAC1 and HDAC2.

    “but their selectivity profiles extended well beyond these isoforms as reported previously (12, 13, 26, 29, 30, 38).”
  • Previous reports postulate that an intramolecular hydrogen bond between the amine and carbonyl must be broken to permit successful zinc chelation, and a desolvation penalty is paid for this rearrangement.

    “This is consistent with previous reports postulating that an intramolecular hydrogen bond between the amine and carbonyl must be broken to permit successful zinc chelation, and a desolvation penalty is paid for this rearrangement to occur (1, 25-28, 34).”

    From Histone Deacetylase (HDAC) Inhibitor Kinetic Rate Constants Correlate with Cellular Histone Acetylation but Not Transcription and Cell Viability (2013) · cites this paper as [26]

    The Discussion describes zinc chelation and a hydrogen bond between an HDAC active-site residue and a hydroxamate carbonyl, but not an intramolecular bond between an amine and carbonyl. Searches for that bond and for a desolvation penalty found no passage addressing either proposed step; page numbers are unavailable in our copy. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Class IIa enzymes, HDAC3, HDAC8, and HDAC11 removed the non-physiological Ktfa substrate.

    “Class IIa enzymes (Lahm et al., 2007) as well as HDAC3 (Madsen and Olsen, 2012a), HDAC8 (Bradner et al., 2010), and HDAC11 (Inks et al., 2012) removed the physiologically non-relevant trifluoroacetamide (Ktfa).”

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.
