Dual‐Function CXCR4 Antagonist Polyplexes To Deliver Gene Therapy and Inhibit Cancer Cell Invasion

Abstract

Giving a one-two punch: A bicyclam-based biodegradable polycation with CXCR4 antagonistic activity shows potential for combining cancer chemotherapy with gene therapy or siRNA therapy. This dual-function polycation prevents cancer cell invasion by inhibiting CXCL12-stimulated CXCR4 activation (see scheme), while at the same time efficiently and safely delivering therapeutic DNA into cancer cells.
