Novel antibacterial polymeric nanocomposite for smart co-delivery of anticancer drugs

Artif Cells Nanomed Biotechnol. 2017 Dec;45(8):1509-1520. doi: 10.1080/21691401.2016.1260576. Epub 2016 Nov 29.

Abstract

Here a novel antibacterial nanocomposite was developed for combination cancer therapy. The synthesized nanocarrier was characterized by FTIR, 1H NMR, thermogravimetric analysis (TGA), and FESEM-EDX. Its antibacterial activity was assessed by determining minimum inhibitory concentration (MIC) values. Doxorubicin (DOX) and methotrexate (MTX) conjugation with nanocarrier sustained the release of both drugs with apparent pH-triggered manner. Co-administration of DOX with MTX leads to an efficient anticancer performance to MCF7 cell lines verified by qRT-PCR and MTT assay tests. It was concluded that this novel drug delivery vehicle makes antibacterial and anticancer therapeutic processes proceed spontaneously, representing more efficient drug delivery system in nanomedicine.
