, (2021/08/13)
The present disclosure relates to compounds and methods for modulating the expression of dmpk, and treating diseases and conditions in which dmpk plays an active role. The compound can be a transcription modulator molecule having a first terminus, a second terminus, and oligomeric backbone, wherein: a) the first terminus comprises a DNA-binding moiety capable of noncovalently binding to a nucleotide repeat sequence CAG or CTG; b) the second terminus comprises a protein-binding moiety binding to a regulatory molecule that modulates an expression of a gene comprising the nucleotide repeat sequence CAG or CTG; and c) the oligomeric backbone comprising a linker between the first terminus and the second terminus.

Proteolysis targeting chimeras (PROTACs) represent a new class of promising therapeutic modalities. PROTACs hijack E3 ligases and the ubiquitin-proteasome system (UPS), leading to selective degradation of the target proteins. However, only a very limited number of E3 ligases have been leveraged to generate effective PROTACs. Herein, we report that the KEAP1 E3 ligase can be harnessed for targeted protein degradation utilizing a highly selective, noncovalent small-molecule KEAP1 binder. We generated a proof-of-concept PROTAC, MS83, by linking the KEAP1 ligand to a BRD4/3/2 binder. MS83 effectively reduces protein levels of BRD4 and BRD3, but not BRD2, in cells in a concentration-, time-, KEAP1- and UPS-dependent manner. Interestingly, MS83 degrades BRD4/3 more durably than the CRBN-recruiting PROTAC dBET1 in MDA-MB-468 cells and selectively degrades BRD4 short isoform over long isoform in MDA-MB-231 cells. It also displays improved antiproliferative activity than dBET1. Overall, our study expands the limited toolbox for targeted protein degradation.

As one of the most aggressive and lethal human malignancies with extremely poor prognosis, there is an urgent demand of more effective therapy for the treatment of pancreatic cancer. Reported here is a new, effective therapeutic strategy and the design of small-molecule inhibitors that simultaneously target bromodomain and extra-terminal (BET) and histone deacetylase (HDAC), potentially serving as promising therapeutic agents for pancreatic cancer. A highly potent dual inhibitor (13 a) is identified to possess excellent and balanced activities against BRD4 BD1 (IC50=11 nm) and HDAC1 (IC50=21 nm). Notably, this compound shows higher in vitro and in vivo antitumor potency than the BET inhibitor (+)-JQ1 and the HDAC inhibitor vorinostat, either alone or and in combination, highlighting the advantages of BET/HDAC dual inhibitors for more effective treatment of pancreatic cancer.
