SAR by NMR: Putting the Pieces Together

Pharmaceutical Discovery Division, Abbott Laboratories, Abbott Park, IL 60064

It has been nearly ten years since the introduction of SAR by NMR and the advent of fragment-based drug design. During this time, we have gained a tremendous amount of knowledge about protein druggability, the limits of chemical diversity, and crafting high-affinity ligands from low molecular weight, weakly binding leads. This review will describe the concept of fragment-based drug design, discuss why it works, and illustrate the power of the approach with two case studies on the design of potent inhibitors of matrix metalloproteinases and Bcl-2 family proteins.
