FBDD
FBDD

Fragment-based drug screening involves the identification of small molecule fragments that weakly interact with the target protein using various interaction methods. Subsequently, based on their structural information, these active fragments are optimized to obtain lead compounds with higher activity for the development of new drugs.

Key Features

Diverse Fragment Libraries

Our diverse fragment libraries are designed to cover a broad chemical space, ensuring high hit rates and efficient identification of binding sites.

Advanced Screening Techniques

Utilizing Enzyme activity experiment, X-ray crystallography, SPR, and other biophysical methods, we can rapidly identify and characterize fragment interactions.

Efficient Fragment Optimization

Through fragment growth, linking, and merging strategies, we transform initial hits into high-affinity lead compounds.

Technical Workflow
01
Target Conformation & Library Selection
    • Gene contrust design
    • Protein expression
    • Protein purification
02
Assay development(Primary Single-dose Screening)
    • SPR
    • TRIC
    • ASMS
    • nanoDSF
03
Hit Validation
    • Kd Confirmation: SPR\MST\TRIC\ITC
    • Binding Confirmation: nanoDSF
    • Function Confirmation: Enzymatic assay
04
Structural Elucidation Soaking/co-crystallography
    • Used to determine the binding mode of the fragment with the target protein and the structure of the complex, the success of structural elucidation directly impacts the subsequent fragment optimization and the development of lead compounds in FBDD.
