Co-delivery of baicalein and doxorubicin by hyaluronic acid decorated nanostructured lipid carriers for breast cancer therapy

Abstract

Purpose: Combination anticancer therapy is promising to generate synergistic anticancer effects, to maximize the treatment effect and to overcome multi-drug resistance. Nanostructured lipid carriers (NLCs), composed of solid and liquid lipids, and surfactants are potentially good colloidal drug carriers. The aim of this study is to construct a hyaluronic acid (HA) decorated NLCs as nanocarriers for co-delivery baicalein (BCL) and doxorubicin (DOX). Methods: BCL-and DOX-loaded NLCs (BCL/DOX-NLCs) were prepared. HA ligands were used for the decoration of BCL/DOX-NLCs to form HA decorated BCL/DOX-NLCs (HA-BCL/DOX-NLCs). The in vitro cytotoxicity studies of different formulations were evaluated on DOX drug-resistant MCF-7 breast cancer cell line (MCF-7/ADR cells). In vivo anti-tumor effects were observed on the murine bearing MCF-7/ADR cells model. Results: HA-BCL/DOX-NLCs showed highest cytotoxicity and synergistic effect of two drugs in tumor cells in vitro. The in vivo study revealed the greatest anti-tumor activity than all the other formulations in the murine breast cancer model. Conclusions: HA decorated NLCs could be used as a novel carrier to co-delivery BCL and DOX for breast cancer therapy. HA-BCL/DOX-NLCs could be a promising targeted and combinational therapy nanomedicine.

Lymph cancer chemotherapy: delivery of doxorubicin-gemcitabine prodrug and vincristine by nanostructured lipid carriers

“…[42][43][44][45] Nanocarriers using lipids to load drugs form a carrier system with a number of desirable features, including a low toxicity, a biodegradable particulate matrix, nontoxic degradation products, a high capacity to incorporate lipophilic and hydrophilic drugs, a controlled release of the incorporated drug, and easy scale-up at low cost. 46 For this purpose, different types of lipid carriers, including lipid-drug conjugates, SLNs, and NLCs, have been developed. NLCs represent a new generation of lipid nanoparticles, which are developed through the combination of advantages from different nanocarriers, including liposomes and SLN systems.…”

Liver-targeting self-assembled hyaluronic acid-glycyrrhetinic acid micelles enhance hepato-protective effect of silybin after oral administration

“…Among them, hyaluronic acid (HA), a non-toxic, biocompatible and biodegradable polysaccharide, has gained intense attention due to its potential as drug delivery carrier (Almeida et al, 2014;Laffleur et al, 2014;Liu et al, 2015). Many studies have reported that HA receptors in human body played important biological roles, such as endocytosis, degradation and signal transduction (Oh et al, 2010).…”

Etoposide-loaded nanostructured lipid carriers for gastric cancer therapy

“…Lipid-based nanoparticles can be considered as a versatile tool with a high potential of applications, including a high capacity to incorporate lipophilic and hydrophilic drugs, a biocompatible and biodegradable matrix and well-established safety profiles (Esposito et al, 2015;Liu et al, 2015). They combine advantages of colloidal drug carrier systems such as emulsions, liposomes and polymeric nanoparticles.…”
