Abstract

Immunomodulatory drugs (IMiDs) exert anti-myeloma activity by binding to the protein cereblon (CRBN) and subsequently degrading IKZF1/3. Recently, their ability to recruit E3 ubiquitin ligase has been used in the proteolysis targeting chimera (PROTAC) technology. Herein, we design and synthesize a novel IMiD analog TD-106 that induces the degradation of IKZF1/3 and inhibits the proliferation of multiple myeloma cells in vitro as well as in vivo. Moreover, we demonstrate that TD-428, which comprises TD-106 linked to a BET inhibitor, JQ1 efficiently induce BET protein degradation in the prostate cancer cell line 22Rv1. Consequently, cell proliferation is inhibited due to suppressed C-MYC transcription. These results, therefore, firmly suggest that the newly synthesized IMiD analog, TD-106, is a novel CRBN modulator that can be used for targeted protein degradation.

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.
