N-TERMINAL MODIFIED PEG-TRAIL, METHOD FOR PREPARING AND USES THEREOF

摘要

Disclosed herein are an N-terminal modified PEG-TRAIL conjugate and a preparation method and use thereof. The PEG-TAIL conjugate has pharmaceutical activity identical or similar to that of native TRAIL (TNF-related apoptosis-inducing ligand) with extended in vivo half-life and enhanced stability. Compared to native TRAIL, the PEG-TAIL conjugate exhibits high solubility and solution stability, with highly improved pharmacokinetic profiles. Thus, the PEG-TAIL conjugate may be very useful for preventing and treating proliferative diseases and autoimmune diseases.
