Abstract

Thalidomide, lenalidomide and pomalidomide are immunomodulatory drugs (IMiDs) effective in the treatment of multiple myeloma, myelodysplastic syndrome (MDS) with deletion of chromosome 5q and other hematological malignancies. Recent studies showed that IMiDs bind to CRBN, a substrate receptor of CRL4 E3 ligase, to induce the ubiquitination and degradation of IKZF1 and IKZF3 in multiple myeloma cells, contributing to their anti-myeloma activity. Similarly, lenalidomide exerts therapeutic efficacy via inducing ubiquitination and degradation of CK1α in MDS with deletion of chromosome 5q. Recently, novel thalidomide analogs have been designed for better clinical efficacy, including CC-122, CC-220 and CC-885. Moreover, a number of neo-substrates of IMiDs have been discovered. Proteolysis-targeting chimeras (PROTACs) as a class of bi-functional molecules are increasingly used as a strategy to target otherwise intractable cellular protein. PROTACs appear to have broad implications for novel therapeutics. In this review, we summarized new generation of immunomodulatory compounds, their potential neo-substrates, and new strategies for the design of novel PROTAC drugs.

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.
