Abstract

Summary: Over the past several years, there has been an increasing research effort focused on inhibition of protein–protein interactions (PPI s) to develop novel therapeutic approaches for cancer, including hematologic malignancies. These efforts have led to development of small molecule inhibitors of PPI s, some of which already advanced to the stage of clinical trials while others are at different stages of preclinical optimization, emphasizing PPI s as an emerging and attractive class of drug targets. Here, we review several examples of recently developed inhibitors of PPI s highly relevant to hematologic cancers. We address the existing skepticism about feasibility of targeting PPI s and emphasize potential therapeutic benefit from blocking PPI s in hematologic malignancies. We then use these examples to discuss the approaches for successful identification of PPI inhibitors and provide analysis of the protein–protein interfaces, with the goal to address ‘druggability’ of new PPI s relevant to hematology. We discuss lessons learned to improve the success of targeting new PPI s and evaluate prospects and limits of the research in this field. We conclude that not all PPI s are equally tractable for blocking by small molecules, and detailed analysis of PPI interfaces is critical for selection of those with the highest chance of success. Together, our analysis uncovers patterns that should help to advance drug discovery in hematologic malignancies by successful targeting of new PPI s.

  • Another disadvantage of targeting the active site of kinases is that those inhibitors are highly susceptible to resistance arising from mutations in the catalytic domain, such as drug resistance to imatinib in chronic myeloid leukemia patients.

  • While many cancers are driven by aberrant kinase activity, it is thought that targeting the PPIs that regulate the activity of a specific kinase is a more viable approach to develop selective kinase inhibitors than targeting the conserved ATP binding site of kinases directly.

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.
