Adenosine triphosphate/pH dual-responsive controlled drug release system with high cancer/normal cell selectivity and low side toxicity

J Biomater Appl. 2022 Aug;37(2):324-332. doi: 10.1177/08853282221087412. Epub 2022 Apr 15.

Abstract

Most drug-delivery systems (DDS) suffer from poor selectivity to cancer/normal cells or the complicated synthetic process. Herein, we employed a novel facile method to develop an oligodeoxy nucleotides based DDS composed with adenosine-5'- triphosphate (ATP) aptamer and a pH responsive cytosine (C) DNA fragment for specific daunomycine (DNM) delivery. The DDS has ATP/pH dual-responsive drug release, can selectively internalize into tumor cell lines and thus has ultrahigh cancer/normal cell selectivity over the individual drug. The non-chemical synthesis, controllable dual-responsive intracellular drug release, and high cancer/normal cell selectivity endowed the DDS high biocompatibility and significant tumor suppression.

Keywords: adenosine triphosphate/pH responsive; biosafety; cancer/normal selectivity; drug-delivery systems; tumor suppression.
