11. Charge Reversible and Mitochondria/Nucleus Dual Target Lipid Hybrid Nanoparticles To Enhance Antitumor Activity of Doxorubicin

Author

Abstract

The experiment aims to increase antitumor activity while decreasing the systemic toxicity of doxorubicin (DOX). Charge reversible and mitochondria/nucleus dual target lipid hybrid nanoparticles (LNPs) was prepared. The in vitroexperimental results indicated that LNPs released more amount of DOX in acidic environment and delivered more amount of DOX to the mitochondria and nucleus of tumor cells than did free DOX, which resulted in the reduction of mitochondrial membrane potential and the enhancement of cytotoxicity of LNPs on tumor cells. Furthermore, the in vivoexperimental results indicated that LNPs delivered more DOX to tumor tissue and significantly prolonged the retention time of DOX in tumor tissue as compared with free DOX, which consequently resulted in the high antitumor activity and low systemic toxicity of LNPs on tumor-bearing nude mice. The above results indicated that charge reversible mitochondria/nucleus dual targeted lipid hybrid nanoparticles greatly enhanced therapeutic efficacy of DOX for treating lung cancer.

Abstract

Melatonin, an endogenous ligand for melatonin receptor, plays an important role in modulating various physiological activities through acting on different subtypes MT1, MT2 or the binding site MT3. The distinct roles of the receptor subtypes provide great potential for receptor-specific pharmacological agents. Melatonin has no subtypeselectivity, so it is very important to develop different subtype-selective ligand for receptor subtype research and drug development. In order to provide guidance for developing high selective ligand, this paper focused on the MT2-selective ligands, which developed well in the past years. The MT2-selective ligands, mainly focusing on binding data on MT1 and MT2 receptor, are reviewed in detail according to their structural classes, and the relative pharmacophore, receptor binding models and the relationship between the structure of ligand and the affinity along with selectivity for receptor subtype were discussed, which may facilitate the exploration of more potent and effective MT2-selective ligands.
