rac-((2R,3S)-3-((tert-butoxycarbonyl)amino)-2-hydroxy-4-phenylbutanoyl)-D-leucine Chemical Properties,Uses,Production

Description

E3 Ligase ligand 9 targets ubiquitin-protein ligases in order to activate the E3 ubiquitin ligase. It can then treat metabolic disorders and psychiatric disorders.

Uses

E3 ligase Ligand 9 is a ligand for E3 ubiquitin ligase. E3 ligase Ligand 9 can be connected to the ligand for protein by a linker to form PROTACs or SNIPERs. PROTACs are inducers of ubiquitination-mediated degradation of cancer-promoting proteins[1].
