Encapsulation and Systemic Delivery of 5-Fluorouracil Conjugated with Silkworm Pupa Derived Protein Nanoparticles for Experimental Lymphoma Cancer. | LitMetric

AI Article Synopsis

Article Abstract

Protein-based drug delivery systems have an edge over conventional drug delivery systems due to their biodegradability, non-antigenicity, and excellent biocompatibility to improve the therapeutic properties of anticancer drugs. This study describes the increased anticancer efficacy of 5-fluorouracil (5-FU) conjugated with silkworm Bombyx mori pupal biowaste derived nanoparticles. Here, we have checked the toxicity of pupa-protein nanoparticles (PpNps) and their potential as a carrier for anticancer drugs. PpNps were prepared by a desolvation method which resulted in a uniform particle size of 162.7 ± 2.9 nm. The 5-FU loaded PpNps were formulated and characterized. The drug content of the developed 5-FU conjugated nanoparticles was evaluated by HPLC analysis. The entrapment efficiency and loading capacity of 5-FU were analyzed by HPLC and determined to be 93% and 88.6%, respectively. The release studies showed the biphasic release of 5-FU at pH 7.4 where rapid drug release was achieved for first 30 min, followed by a sustained release of 5-FU from the developed Nps achieved for the next 8 h. Mice with developed ascites tumors were intraperitoneally treated with 5-FU-PpNps and sacrificed. There was a significant increase in total red blood cells and hemoglobulin in 5-FU-PpNps treated mice, whereas a significant decrease in white blood cells which indicated the reduced inflammation of cancer. Subsequently, 5-FU-PpNps decreased the tumor volume and tumor cell viability, which proved its cytotoxic property to cancer cells. This study presents a novel approach to derive B. mori pupal protein nanoparticles, which can be safely used for cancer drug delivery.
