Multi-functionalized single-walled carbon nanotubes as delivery carriers: promote the targeting uptake and antitumor efficacy of doxorubicin
As one of carbon-based nanomaterials, single-walled carbon nanotubes (SWCNTs) are widely regarded as potentially potent drug delivery carriers on account of their prominent properties. Nevertheless, their biomedical application, particularly in the drug delivery field has been seriously restricted by some inherent defects. In this study, SWCNTs materials were functionalized by covalent and non-covalent approaches, respectively. In short, the pristine SWCNTs were first purified with strong oxidizing acids (H2SO4/HNO3), and the resulting carboxylated ones (CNTs) were attached sequentially by different modification agents, including polyethylene glycol (PEG), polyethyleneimine (PEI), folic acid (FA) and chitosan (CS). Various nanocarriers were then systematically characterized and comparatively evaluated. The results illustrated that all CNTs samples could act as drug delivery carriers since they had high drug loading efficiency, good biocompatibility and responsive drug release. In comparison with other CNTs, multi-functionalized ones (CNTs-PPFC) exhibited more excellent performance, such as rapid drug release at low pH condition, higher cell internalization efficiency, and enhanced antitumor activity toward MCF-7 cells. These advantages should be attributed to their better dispersion state and comparably higher affinity with tumor cells, which favor the more efficient selective cellular uptake and subsequent drug accumulation. Moreover, further pharmacological mechanism analysis also revealed that CNTs-PPFC/DOX could induce the apoptosis of MCF-7 cells most effectively, by triggering ROS overproduction and affecting cell cycle distribution. In conclusion, the multi-functionalized CNTs-PPFC can be utilized as promising nanocarriers, and the findings will contribute to the rational design of novel delivery vehicles for anticancer drugs.
期刊介绍:
The Journal of Inclusion Phenomena and Macrocyclic Chemistry is the premier interdisciplinary publication reporting on original research into all aspects of host-guest systems. Examples of specific areas of interest are: the preparation and characterization of new hosts and new host-guest systems, especially those involving macrocyclic ligands; crystallographic, spectroscopic, thermodynamic and theoretical studies; applications in chromatography and inclusion polymerization; enzyme modelling; molecular recognition and catalysis by inclusion compounds; intercalates in biological and non-biological systems, cyclodextrin complexes and their applications in the agriculture, flavoring, food and pharmaceutical industries; synthesis, characterization and applications of zeolites.
The journal publishes primarily reports of original research and preliminary communications, provided the latter represent a significant advance in the understanding of inclusion science. Critical reviews dealing with recent advances in the field are a periodic feature of the journal.
