49-57 49-57 Conjugate of biodegradable aliphatic polyester with Tat49-57 peptide or peptide chain containing Tat49-57 peptide and nanoparticle manufactured using the same
PURPOSE: A conjugate of biodegradable aliphatic polyester with Tat49-57 peptide or Tat49-57 peptide-containing peptide chain, and a nanoparticle manufactured using the same conjugate are provided. The cell penetration of the nanoparticle is increased by exposing Tat peptide on the surface of the nanoparticle. CONSTITUTION: A conjugate of biodegradable aliphatic polyester with Tat49-57 peptide having the nucleotide sequence of SEQ ID NO: 1 or Tat49-57 peptide-containing peptide chain is provided, wherein the biodegradable aliphatic polyester is one or more components selected from copolymers manufactured from poly(D-lactic acid), poly(L-lactic acid), poly(D,L-lactic acid), poly(D-lactic acid-co-glycolic acid), poly(L-lactic acid-co-glycolic acid), poly(D,L-lactic acid-co-glycolic acid), poly(caprolactone), poly(valerolactone), poly(hydroxy butyrate), poly(hydroxy valerate), poly(1,4-dioxan-2-one), poly(ortho ester) and monomers thereof. A nanoparticle manufactured using the conjugate of biodegradable aliphatic polyester with Tat49-57 peptide or Tat49-57 peptide-containing peptide chain has average particle size of 1,000 nm or less.
