Synthesis of HDAC Inhibitor Libraries via Microscale Workflow

Area of Science:

• Medicinal Chemistry
• Analytical Chemistry
• Drug Discovery

Background:

• Traditional compound library synthesis requires significant material quantities.
• High-throughput screening necessitates pure compounds at standardized concentrations.
• Limitations in current workflows hinder efficient small-scale library generation.

Purpose of the Study:

• To establish an integrated workflow for microgram-scale synthesis, purification, and biological testing of compound libraries.
• To enable high-fidelity biological testing through precise compound concentration and purity.
• To reduce material requirements and enhance amenability to high-throughput experimentation in drug discovery.

Main Methods:

• Integration of synthesis, purification, and biological testing.
• Utilized mass-directed preparative High-Performance Liquid Chromatography (HPLC).
• Employed Charged Aerosol Detection (CAD) for compound quantification and standardization.

Main Results:

• Successfully generated compound libraries at microgram scale with high purity.
• Achieved standardized concentrations suitable for high-fidelity biological assays.
• Histone deacetylase (HDAC) inhibitor libraries yielded biological data consistent with standard methods.

Conclusions:

• The developed workflow significantly reduces material requirements for compound library generation.
• This approach facilitates high-throughput experimentation and accelerates drug discovery.
• Enables efficient biological testing of small-scale compound libraries.
