HTSDSF Explorer, A Novel Tool to Analyze High-throughput DSF Screenings

Area of Science:

• Biophysics
• Drug Discovery
• Computational Chemistry

Background:

• High-throughput screening (HTS) is crucial for identifying new drug candidates.
• Analyzing differential scanning fluorimetry (DSF) data for target-based assays is often manual and time-consuming.
• Current methods require combining multiple software packages for analyzing melting temperature (T_m) and ligand-induced shifts (ΔT_m).

Purpose of the Study:

• To develop a user-friendly, all-in-one application to simplify DSF data analysis.
• To expedite the identification and validation of primary hits in drug discovery.
• To facilitate the determination of preliminary binding constants (K_D) for validated hits.

Main Methods:

• Developed HTSDSF explorer, a server-client application suite.
• Implemented interactive pre-analysis and display of T_m and ΔT_m.
• Integrated dose-response assay analysis for K_D determination.

Main Results:

• HTSDSF explorer significantly reduces analysis time for primary screenings.
• The application allows rapid interactive study of hundreds of conditions.
• Enables efficient selection of primary hits and ranking of validated hits.

Conclusions:

• HTSDSF explorer streamlines the drug discovery process by simplifying complex biophysical data analysis.
• The application accelerates the identification and validation of potential drug candidates.
• Facilitates faster advancement of drug discovery efforts through efficient hit selection and ranking.
