Area of Science:
- Biochemistry
- Medicinal Chemistry
- Structural Biology
Background:
- The introduction of Structure-Activity Relationship (SAR) by Nuclear Magnetic Resonance (NMR) and fragment-based drug design (FBDD) has revolutionized drug discovery.
- Significant advancements have been made in understanding protein druggability and optimizing ligand affinity from small, weakly binding fragments.
Purpose of the Study:
- To review the fundamental concepts of fragment-based drug design.
- To elucidate the principles behind the efficacy of FBDD.
- To showcase the practical application and power of FBDD through compelling case studies.
Main Methods:
- Review of established principles and methodologies in fragment-based drug design.
- Analysis of Structure-Activity Relationship (SAR) data obtained through NMR techniques.
