K-Ras ligand-Linker Conjugate 3 

K-Ras ligand-Linker Conjugate 3 (Compound 001371) incorporates a ligand for K-Ras recruiting moiety, and a PROTAC linker, which recruit E3 ligases (such as VHL, CRBN, MDM2, and IAP). K-Ras ligand-Linker Conjugate 3 can be used in the synthesis of PROTAC K-Ras Degrader-1 (HY-129523), which is potent PROTAC K-Ras degrader that exhibits ≥70% degradation efficacy in SW1573 cells^[1].

PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins^[1].
