| Research Abstract |
Protein knockdown can be achieved by the use of a small molecule that possesses affinity for both the target protein and ubiquitin ligase. As the ubiquitin ligase, we selected cIAP1 which specifically binds methylbestatin. Several hybrid molecules consisting of methylbestatin and a ligand for various proteins were designed and synthesized. These hybrid molecules induced selective decomposition of the target proteins.
