Abstract

Proteolysis Targeting Chimera (PROTAC) technology is a rapidly emerging alternative therapeutic strategy with the potential to address many of the challenges currently faced in modern drug development programs. PROTAC technology employs small molecules that recruit target proteins for ubiquitination and removal by the proteasome. The synthesis of PROTAC compounds that mediate the degradation of c-ABL and BCR-ABL by recruiting either Cereblon or Von Hippel Lindau E3 ligases is reported. During the course of their development, we discovered that the capacity of a PROTAC to induce degradation involves more than just target binding: the identity of the inhibitor warhead and the recruited E3 ligase largely determine the degradation profiles of the compounds; thus, as a starting point for PROTAC development, both the target ligand and the recruited E3 ligase should be varied to rapidly generate a PROTAC with the desired degradation profile.

  • Over 60 proteins of interest from diverse protein families and structural classes have been successfully degraded using a TPD strategy.

    “Over 60 POIs from diverse protein families and structural classes have been successfully degraded using a TPD strategy.”
  • The pairing of VHL versus CRBN for a given target can result in different degradation efficiencies.

    “the pairing of VHL versus CRBN for a given target can result in different degradation efficiencies49, as was first observed when targeting the fusion oncogene BCR–ABL by PROTACs118.”

  • A major advantage of VHL-based PROTACs is their target-specificity.

    “A major advantage of VHL-based PROTACs is their target-specificity [44, 53].”
  • Using the same BCR-ABL ligands, CRBN-based PROTACs degraded both BCR-ABL and c-ABL, whereas VHL-based PROTACs could only degrade c-ABL.

    “using the same BCR-ABL ligands, the CRBN-based PROTACs degraded both BCR-ABL and c-ABL, whereas VHL-based PROTACs could only degrade c-ABL [44].”
  • PROTACs against BRD4, BTK, BCR-ABL and CDK-6 have shown efficacy in leukemia.

    “For example, PROTACs against BRD4, BTK, BCR-ABL and CDK-6 etc. have shown efficacy in leukemia [22, 44, 58, 60], whereas AR, ER, FAK, P38 PROTACs have been developed against different solid tumors [13, 49, 51, 104] (Table 1).”

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.
