摘要

通过1-(3-二甲基氨基丙基)-3-乙基碳二亚胺和N-羟基丁二酰亚胺反应将透明质酸(hyaluronic acid,HA)和4-羧丁基三苯基溴化膦((4-carboxybutyl)triphenylphosphonium bromide,TPP)分子连接到聚乙二醇-氨基(PEG-NH2)修饰过的黑色素纳米颗粒(melanin nanoparticles,MNP)表面,设计合成了一种具有双靶向能力的黑色素纳米颗粒(MNP-TPP-HA),赋予了黑色素的双靶向能力.体外三维(3D)多细胞肿瘤球荧光成像和活体肿瘤光声成像实验表明MNP-TPP-HA具有优异的肿瘤靶向穿透能力.

Abstract

A dual-targeting melanin nanoparticle(MNP-TPP-HA)was constructed by grafting the carboxyl groups of hyaluronic acid(HA)and(4-carboxybutyl)triphenylphosphonium bromide(TPP)onto the surface of polyethylene glycol-amino(PEG-NH2)modified MNP based on 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride(EDC)and N-hydroxy succinimide(NHS)reaction,endowing melanin with the ability of dual active targeting.The fluorescence imaging of in vitro three-dimensional(3D)tumor models and in vivo photoacoustic imaging(PAI)all reveal the excellent target penetration ability of MNP-TPP-HA.
