New small molecule inhibitors target bromodomain proteins, including BET family members like BRD4, for cancer and inflammatory diseases. Research strategies aim to overcome toxicity challenges for these epigenetic drugs.
Area of Science:
- Epigenetics
- Molecular Biology
- Drug Discovery
Background:
- Bromodomains recognize acetylated lysine, regulating gene transcription and chromatin remodeling.
- Bromodomain and extra terminal (BET) proteins, like BRD4, are implicated in cancer and inflammation.
- BET inhibitors show therapeutic promise but face dose-limiting toxicities.
Purpose of the Study:
- To review new-generation small molecule inhibitors for BET and non-BET bromodomain proteins.
- To discuss research strategies for targeting bromodomains in human diseases.
Main Methods:
- Review of current literature on small molecule bromodomain inhibitors.
- Analysis of research strategies for targeting BET and non-BET bromodomains.
Main Results:
- Development of novel small molecule inhibitors targeting bromodomain proteins.
- Identification of strategies to manage on-target toxicities associated with epigenetic drugs.
Conclusions:
- New bromodomain inhibitors offer therapeutic potential for cancers and inflammatory disorders.
- Targeting bromodomains requires careful strategy to balance efficacy and safety.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
