PEGylation: a promising strategy to overcome challenges to cancer-targeted nanomedicines: a review of challenges to clinical transition and promising resolution
On account of heterogeneity, intrinsic ability of drug resistance, and the potential to invade to other parts of the body (malignancy), the development of a rational anticancer regimen is dynamically challenging. Chemotherapy is considered the gold standard for eradication of malignancy and mitigati...

description |
On account of heterogeneity, intrinsic ability of drug resistance, and the potential to invade to other parts of the body (malignancy), the development of a rational anticancer regimen is dynamically challenging. Chemotherapy is considered the gold standard for eradication of malignancy and mitigation of its reoccurrence; nevertheless, it has also been associated with detrimental effects to normal tissues owing to its nonselectivity and nominal penetration into the tumor tissues. In recent decades, nanotechnology-guided interventions have been well-acclaimed due to their ability to facilitate target-specific delivery of drugs, avoidance of nontarget distribution, alleviated systemic toxicity, and maximized drug internalization into cancer cells. Despite their numerous biomedical advantages, clinical translation of nanotechnology-mediated regimens is challenging due to their short plasma half-life and early clearance. PEGylation of nanomedicines has been adapted as an efficient strategy to extend plasma half-life and diminished early plasma clearance via alleviating the opsonization (uptake by monocytes and macrophages) of drug nanocarriers. PEGylation provides Bstealth^ properties to nanocarrier’s surfaces which diminished their recognition or uptake by cellular immune system, leading to longer circulation time, reduced dosage and frequency, and superior site-selective delivery of drugs. Therefore, this review aims to present a comprehensive overview of the pharmaceutical advantages and therapeutic feasibility of PEGylation of nanocarriers in improving tumor-specific targetability, reversing drug resistance, and improving pharmacokinetic profile of drugs and anticancer efficacy. Challenges to PEGylated cancer nanomedicines, possible adaptations to resolve those challenges, and pivotal requirement for interdisciplinary research for development of rational anticancer regimen have also been pondered. © Controlled Release Society 2019. |
