|---|---|
| Synonym | More Synonyms |
| Description | Br-C3-methyl ester is a Alkyl/ether-based PROTAC linker that can be used in the synthesis of PROTAC PD-1/PD-L1 degrader-1 (HY-131183)[1]. |

| Related Catalog | Research Areas >> Cancer Signaling Pathways >> PROTAC >> PROTAC Linker |
| Target | Alkyl/ether |
| In Vitro | 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]. |
