NH2-C4-NH-Boc (compound 15) is a PROTAC linker of the Alkyl ether class, suitable for synthesizing various PROTAC molecules.

Biotin-PEG2-C4-alkyne, a PEG-based linker for PROTACs, connects two essential ligands crucial for forming PROTAC molecules, enabling selective protein degradation through the ubiquitin-proteasome system within cells.

Pomalidomide-amido-C4-amido-PEG2-C2-NH-Boc is a novel synthesized conjugate compound functioning as an E3 ligase ligand-linker in PROTAC technology. Incorporating a Pomalidomide-derived cereblon ligand that selectively binds to the E3 ligase cereblon and a 2-unit PEG linker, it provides stability and flexibility to the conjugate.

(S,R,S)-AHPC-PEG2-C4-Cl is a small molecule HaloPROTAC, comprising the (S,R,S)-AHPC based VHL ligand and a 2-unit PEG linker, that induces the degradation of GFP-HaloTag7 in cell-based assays[1].

PEG3-C4-OBn, a polyethylene glycol (PEG)-based PROTAC linker, is utilized in crafting the PROTAC SGK3 degrader-1, a potent SKG3 degrader leveraging PROTAC technology [1][2].

Boc-NH-PEG2-C2-amido-C4-acid (PROTAC Linker 30) is a polyethylene glycol (PEG)-based linker used in the synthesis of Proteolysis Targeting Chimeras (PROTACs)[1].

NH2-Ph-C4-acid-NH2-Me (PROTAC Linker 31) is an alkyl chain-based compound used in the synthesis of PROTACs [1].
