Development of novel Asf1-H3/H4 inhibitors

Area of Science:

• Molecular Biology
• Cancer Therapeutics
• Drug Discovery

Background:

• The histone chaperone anti-silencing function 1 (Asf1) plays a critical role in chromatin packaging, regulating DNA-dependent nuclear processes.
• Asf1 is implicated in normal growth, development, and differentiation, and is a potential therapeutic target for various cancers.

Purpose of the Study:

• To identify novel inhibitors of the Asf1-histone H3/H4 interaction.
• To develop potential therapeutic agents for cancer treatment by targeting Asf1.

Main Methods:

• High-throughput screening (HTS) was employed to identify initial lead compounds.
• Medicinal chemistry efforts focused on optimizing HTS leads to develop a series of N-acyl hydrazones.

Main Results:

• A novel series of N-acyl hydrazones were identified as inhibitors of the Asf1-histone H3/H4 interaction.
• These compounds represent the first chemical entities demonstrated to disrupt the Asf1-H3/H4 complex.

Conclusions:

• N-acyl hydrazones are effective inhibitors of the Asf1-histone H3/H4 interaction.
• These findings present a new class of compounds with potential for developing anti-cancer therapies targeting Asf1.
