amino-peg-25-acid

Amino-PEG25-acid is a PEG-based linker for PROTACs that joins two essential ligands, crucial for PROTAC molecule formation. This linker facilitates selective protein degradation by leveraging the ubiquitin-proteasome system within cells.

N-Hexadecyl-pSar25 is a polypeptide derived from polysarcosine (pSar), featuring a hexadecyl head group and a 25-unit polysarcosine tail. Sarcosine, an amino acid derivative, is being explored as a PEG substitute for in vivo applications due to its biodegradability and significantly reduced antigenicity. This N-Hexadecyl-pSar25 can be utilized in the development of lipid nanoparticles.

N-Tetradecyl-pSar25 is a poly(sarcosine) (pSar) derivative composed of a tetradecyl hydrophobic head group covalently linked to a polymeric tail containing 25 repeating poly(sarcosine) units. Sarcosine, the amino acid derivative forming the backbone of this compound, is being developed as a potential substitute for polyethylene glycol (PEG) in in vivo applications due to its advantageous characteristics, which include enhanced biodegradability and substantially reduced antigenicity. N-Tetradecyl-pSar25 is particularly relevant in the formulation and development of lipid nanoparticles, where its structural design contributes to improved delivery and biocompatibility profiles.
