An eco-friendly polysaccharide (PSP001) isolated from the fruit rind of Punica granatum is a biodegradable polymer with immunostimulatory and anticancer properties. PSP001 was employed for the stimuli-responsive targeted delivery of antineoplastic agent doxorubicin (Dox) by the fabrication of Dox-holding PSP nanoparticles (DPN). The galactose moieties of PSP001 were occupied as an effective tumor-targeted motif against the over-expressed asialoglycoprotein and galectin receptors of cancers. DPN followed a pH-sensitive cargo release kinetics, competent cancer cell internalization profile, and appealing biocompatibility towards peripheral red blood cells. The selective execution of caspase-mediated programmed cell death by the DPN on cancer cells was confirmed with multiple apoptosis studies. Extensive toxicity profiling on BALB/c mice rules out any palpable signs of abnormality with DPN administration while bare Dox produced vital signs of toxicity. Studies on syngraft solid tumor-bearing mice uncovered the tumor homing nature of DPN with the subsequent release of the entrapped drug which further translated in the direction of a significant reduction in the tumor payload and enhanced survival benefits, thus offering a robust approach towards endurable cancer management.
