Ligand Discovery and Design Service

Ligand Discovery and Design Service

Molecular targeting of specific proteins by small molecules is one of the key issues in biological research. Such small molecules and peptides, may be useful reagents for further biological research or may form the basis for early-stage drug discovery. Recently, small compounds based PROTAC and peptide based PROTAC have been used in more and more disease research.

Profacgen can provides ligand discovery and design services for both of small compounds based PROTAC and peptide based PROTAC. With our large compounds libraries, virtual screening (molecular docking) can be used in small molecular ligand discovery and design. Based the structure data base, peptide ligand for E3 ligase or target protein will be optimized and designed.
