Multistep Process

The poor understanding of the complex multistep process taken by nanocarriers during the delivery process limits the delivery efficiencies and further hinders the translation of these systems into medicine. Here, we describe a series of six self-assembled nanocarrier types with systematically altered physical properties including size, shape, and rigidity, as well as both in vitro and in vivo analyses of their performance in blood circulation, tumor penetration, cancer cell uptake, and anticancer efficacy. We also developed both data and simulation-based models for understanding the influence of physical properties, both individually and considered together, on each delivery step and overall delivery process. Thus, beyond finding that nanocarriers that are simultaneously endowed with tubular shape, short length, and low rigidity outperformed the other types, we now have a suit of theoretical models that can predict how nanocarrier properties will individually and collectively perform in the multistep delivery of anticancer therapies.

Objective: Docetaxel (DTX), a potent anticancer drug, is suffering from non-specificity and drug resistance as major limitations. In this investigation, we developed Hyaluronic acid (HA)-Docetaxel conjugate (HA-DTX) loaded nanoliposomes to target cancer cells via passive and active targeting approaches. Methods: HA-DTX was synthesized and characterized by UV-Visible spectrophotometry, FT-IR spectroscopy, 1H NMR spectroscopy, Differential scanning calorimetry and X-ray diffraction and then loaded into nanoliposomes (L-NLs) by thin-film hydration method. L-NLs were characterized physicochemically and evaluated for anticancer efficacy by in vitro cytotoxicity study in glioma cells (C6 glial cells); cellular uptake and apoptotic effect were investigated by fluorescence microscopy. Results: HA-DTX was successfully synthesized; L-NLs had an average size of 123.0±16.53 nm, polydispersity index of 0.246±0.01 and zeta potential of 44.4±6.79 mV. Also, L-NLs exhibited 90.54%±4.22 of drug loading efficiency and 2.68%±0.12 of drug loading, releasing about 57.72%±1.17 at pH 5.2 and only 14.14%±1.32 at pH 7.4 after 48 h. No significant change instability was observed after storage at 5 °C±3 °C as well as at 25 °C±2 °C/60% RH±5% RH for 6 mo. The cytotoxicity effect of L-NLs was higher by 10% that of marketed formulation at 10 µg/ml docetaxel concentration. Fluorescence microscopic investigation showed that more cellular uptake and apoptotic effect were observed in L-NLs treated C6 glial cells than in those treated with the marketed formulation. Conclusion: HA-DTX loaded nanoliposomes enabled docetaxel to target C6 glial cells with better efficacy and might be effective to treat glioma.

Targeted Drug

A drug co-delivery system composed of selenium nanoparticles (SeNPs) has attracted increasing interest due to its ability to increase the anticancer efficacy against multidrug-resistant cancer cells. In this study, a cancer-targeted drug co-delivery system combining fluorescein-loaded liposomes and SeNPs was designed and evaluated. The system was developed by coating SeNPs and fluorescein-loaded liposomes with folic acid-chitosan conjugates (FA-CS-SeNPs-Lips). Folic acid-chitosan conjugates (FA-CS) were synthesized by coupling folic acid (FA) with chitosan (CS), and the structure was confirmed by performing Fourier transform spectroscopy (FT-IR) and nuclear magnetic resonance (1H-NMR) spectroscopy. Dynamic light scattering (DLS) measurements and transmission electron microscopy (TEM) were used to evaluate the particle size, Zeta potential, and morphology. The cytotoxicity of SeNPs coated with FA-CS conjugates (FA-CS-SeNPs) toward A549 cells and HeLa cells was examined using the MTT assay. The cancer-targeting ability and drug release behaviors were evaluated in vitro by measuring the cellular uptake of fluorescein and dialysis, respectively. The FA-CS-SeNPs were uniform, spherical particles with a ~50 nm diameter and high positive Zeta potential (+57.7 mV). Based on the results of the MTT assay, FA-CS-SeNPs displayed a more significant increase in the anticancer efficacy in HeLa cells than CS-SeNPs. FA-CS-SeNPs-Lips not only slowly released fluorescein but also specifically targeted HeLa cells through selective binding between folate and folate receptors to increase the cellular uptake of fluorescein.

Photodynamic therapy (PDT) is an innovative and promising modality to treat various tumors. In this study, two novel zinc(II) phthalocyanines substituted with quinolin-8-yloxy groups at the [Formula: see text]-position, namely mono(quinolin-8-yloxy) zinc(II) phthalocyanine (ZnPc-Q1) and tetra(quinolin-8-yloxy) zinc(II) phthalocyanine (ZnPc-Q4), have been synthesized and fully characterized. With quinolin-8-yloxy, these two phthalocyanines exhibit less self-aggregation in DMF and culture medium, high singlet oxygen quantum yields, mitochondria localization and high photodynamic activities (IC[Formula: see text] values as low as 2 nM). Compared to ZnPc-Q4, ZnPc-Q1 exhibits higher cellular uptake and lower IC[Formula: see text] values. Benefitting from its higher anticancer efficacy and lack of isomers, ZnPc-Q1 is a highly promising anticancer agent in clinical application.

The objective of this study was the synthesis of folic acid- (FA-) targeted polymeric micelles of Synperonic PE/F 127-cholesteryl hemisuccinate (PF127-Chol) for specific delivery of docetaxel (DTX). Targeted or nontargeted micelles loaded with DTX were prepared via dialysis method. The effects of processing variables on the physicochemical properties of targeted micelles were evaluated using a full factorial design. After the optimization of the polymer/drug ratio, the organic solvent type used for the preparation of the micelles, and the temperature of dialyzing medium, thein vitrocytotoxicity and cellular uptake of the optimized micelles were studied on B16F10 melanoma cells by flow cytometry and fluorescent microscopy. The anticancer efficacy of DTX-loaded FA-PF127-Chol was evaluated in mice bearing melanoma tumor. Optimized targeted micelles had the particle size of 171.3 nm, zeta potential of −7.8 mV, PDI of 0.325, and a high encapsulation efficiency that released the drug within 144 h. The MTT assay indicated that targeted micelles carrying DTX were significantly more cytotoxic, had higher cellular uptake, and reduced the tumor volume significantly more than the nontargeted micelles and the free drug. FA-PF127-Chol could be, therefore, a promising biomaterial for tumors overexpressing folate receptors.
