Theranostic tumor homing nanocarriers for the treatment of lung cancer.

ABSTRACT: The drugs/strategies to selectively inhibit tumor blood supply have generated interest in recent years for enhancement of cancer therapeutics. The objective of this study was to formulate tumor homing PEGylated CREKA peptide conjugated theranostic nanoparticles of DIM-C-pPhC6H5 (DIM-P) and investigate in vivo antitumor activity as well as evaluate the targeted efficiency to lung tumors using imaging techniques. DIM-P loaded Nanoparticles (NCs-D) were prepared using lipids, and DOGS-NTA-Ni and the surface of NCs-D were modified with PEGylated CREKA peptide (PCNCs-D). PCNCs-D showed 3 fold higher binding to clotted plasma proteins in tumor vasculature compared to NCs-D. PCNCs-D showed 26%±4% and 22%±5% increase in tumor reduction compared to NCs-D in metastatic and orthotopic models respecti
