Peptide-Aptamer Coassembly Nanocarrier for Cancer Therapy

Bioconjug Chem. 2019 Mar 20;30(3):536-540. doi: 10.1021/acs.bioconjchem.8b00903. Epub 2019 Feb 7.

Abstract

We reported methionine bis-alkylated nonapeptide Wpc as an efficient siRNA vehicle previously. Herein, we report an aptamer could also spontaneously coassemble with Wpc to form uniformed nanoparticles for efficient delivery. This unique peptide-based aptamer nanocarrier showed significantly improved cell penetration and antiproliferation effect with high biocompatibility toward various cancer cell lines.
