TLDR
Nanoparticles show their promise for improving the efficacy of drugs with a narrow therapeutic window or low bioavailability, such as anticancer drugs and nucleic acid-based drugs.
Abstract
Nanoparticles show their promise for improving the efficacy of drugs with a narrow therapeutic window or low bioavailability, such as anticancer drugs and nucleic acid-based drugs. The pharmacokinetics (PK) and tissue distribution of the nanoparticles largely define their therapeutic effect and toxicity. Chemical and physical properties of the nanoparticles, including size, surface charge, and surface chemistry, are important factors that determine their PK and biodistribution. The intracellular fate of the nanoparticles after cellular internalization that affects the drug bioavailability is also discussed. Strategies for overcoming barriers for intracellular delivery and drug release are presented. Finally, future directions for improving the PK of nanoparticles and perspectives in the field are discussed.

A New Concept for Macromolecular Therapeutics in Cancer Chemotherapy: Mechanism of Tumoritropic Accumulation of Proteins and the Antitumor Agent Smancs

TL;DR: It is speculated that the tumoritropic accumulation of smancs and other proteins resulted because of the hypervasculature, an enhanced permeability to even macromolecules, and little recovery through either blood vessels or lymphatic vessels in tumors of tumor-bearing mice.
