Facile and One-step Direct Synthesis of Poly(valine)as a Robust Drug Nanocarrier for Enhanced Breast Cancer Therapy
文献摘要：
Synthetic poly(amino acid)s with good biodegradable and biocompatible properties have attracted increased attention as carriers in biomedical applications in recent years,their synthesis and purification procedures are usually complicated and some by-products would occur yet.Given this,polypeptide with good biodegradable and biocompatible properties is prepared and optimized by one-step and direct synthesis strategy and poly(valine)(PVal)is selected here as a model polypeptide in this study.This newly generated PVal can self-assemble into poly(valine)nanoparticles(PVal-NPs)with a high drug-loading capacity(＞20 wt％)of doxorubicin(DOX)and shows strong cytotoxicity against 4T1 cells.Upon cellular internalization,the release of DOX could be accelerated by the endosomal acidic environment which leads to enhanced anticancer effects.The results in vivo show that DOX@PVal-NPs have a long blood circulation time,high cancer accumulation and penetration,and good therapeutic performance in 4T1 tumor-bearing mice without causing obvious adverse effect on main organs.With these combined advantages,these PVal-based nanoplatform would provide an effective drug delivery tool for clinical breast cancer therapy.
