Development and evaluation of a new modular nanotransporter for drug delivery into nuclei of pathological cells expressing folate receptors.

ABSTRACT:

Purpose

Modular nanotransporters (MNTs) are artificial multifunctional systems designed to facilitate receptor-specific transport from the cell surface into the cell nucleus through inclusion of polypeptide domains for accomplishing receptor binding and internalization, as well as sequential endosomal escape and nuclear translocation. The objective of this study was to develop a new MNT targeted at folate receptors (FRs) for precise delivery of therapeutic cargo to the nuclei of FR-positive cells and to evaluate its potential, particularly for delivery of therapeutic agents (eg, the Auger electron emitter ¹¹¹In) into the nuclei of target cancer cells.

Methods

A FR-targeted MNT was developed by site-specific derivatization of ligand-free MNT with maleimide-polyethy
