Development of Selective Histone Deacetylase 6 (HDAC6) Degraders Recruiting Von Hippel–Lindau (VHL) E3 Ubiquitin Ligase

Open access

Abstract

Histone deacetylase 6 (HDAC6) is involved in multiple cellular processes such as aggresome formation, protein stability, and cell motility. Numerous HDAC6-selective inhibitors have been developed as cellular chemical tools to elucidate the function of HDAC6. Since HDAC6 has multiple domains that cannot be studied by HDAC6-selective inhibitors, CRISPR-CAS9 and siRNA/shRNA have been employed to elucidate the nonenzymatic functions of HDAC6. However, these genetic methods have many limitations. Proteolysis targeting chimera (PROTAC) is an emerging technology for the development of small molecules that can quickly remove the entire protein in cells. We previously developed multifunctional HDAC6 degraders that can recruit cereblon (CRBN) E3 ubiquitin ligase. These HDAC6 degraders can degrade not only HDAC6 but also neo-substrates of CRBN. They are excellent candidates for the development of anticancer therapeutics, but the multifunctional nature of the CRBN-based HDAC6 degraders has limited their utility as specific chemical probes for the study of HDAC6-related cellular pathways. Herein we report the development of the first cell-permeable HDAC6-selective degraders employing Von Hippel–Lindau (VHL) E3 ubiquitin ligase, which does not have any known neo-substrates. The DC 50 ’s of the most potent compound 3j are 7.1 nM and 4.3 nM in human MM1S and mouse 4935 cell lines, respectively. The D max ’s of 3j in these two cell lines are 90% and 57%, respectively.

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.
