Schisandrin B (Sch B) is a bioactive dibenzocyclooctadiene derizative that is prevalent in the fruit of . Numerous studies have demonstrated that Sch B has a neuroprotective action by reducing oxidative stress and effectively preventing inflammation. It follows that Sch B is a potential treatment for Alzheimer's disease (AD).

The anti-ovarian cancer effect of RPV modified paclitaxel plus schisandra B liposomes in SK-OV-3 cells and tumor-bearing mice.

Aims: Due to poor targeting ability of anti-tumor drugs and self-adaptation of tumors, the chemotherapy of ovarian cancer is still poorly effective. In recent years, the treatment of tumor with nano-targeted agents has become a potential research focus. In this study, a new type of short cell-penetrating peptide RPV-modified paclitaxel plus schisandrin B liposomes were constructed to disrupt VM channels, angiogenesis, proliferation and migration for the treatment of ovarian cancer.

Tumor Microenvironmental Responsive Liposomes Simultaneously Encapsulating Biological and Chemotherapeutic Drugs for Enhancing Antitumor Efficacy of NSCLC.

Background: Non-small cell lung cancer (NSCLC) is one of the most lethal types of cancer with highly infiltrating. Chemotherapy is far from satisfactory, vasculogenic mimicry (VM) and angiogenesis results in invasion, migration and relapse.

Purpose: The objective of this study was to construct a novel CPP modified vinorelbine and dioscin liposomes by two new functional materials, DSPE-PEG-MAL and CPP-PVGLIG-PEG, to destroy VM channels, angiogenesis, EMT and inhibit invasion and migration.

Multifunctional osthole liposomes and brain targeting functionality with potential applications in a mouse model of Alzheimer's disease.

Osthole (Ost) is a coumarin compound and a potential drug for Alzheimer's disease (AD). However, the effectiveness of Ost is limited by solubility, bioavailability, and low permeability of the blood-brain barrier. In this study, we constructed Ost liposomes with modified CXCR4 on the surface (CXCR4-Ost-Lips), and investigated the intracellular distribution of liposomes in APP-SH-SY5Y cells.

Dual variable of drug loaded micelles in both particle and electrical charge on gastric cancer treatment.

Gastric cancer is a malignant tumour characterised by the uncontrolled cell growth. The incidence and mortality of gastric cancer remain high for the invasion and metastasis. We are urgently seeking a risk-free and effective treatment strategy for gastric cancer.

Transferrin-Modified Osthole PEGylated Liposomes Travel the Blood-Brain Barrier and Mitigate Alzheimer's Disease-Related Pathology in APP/PS-1 Mice.

Introduction: Osthole (Ost) is a coumarin compound that strengthens hippocampal neurons and neural stem cells against Aβ oligomer-induced neurotoxicity in mice, and is a potential drug for the treatment of Alzheimer's disease (AD). However, the effectiveness of the drug is limited by its solubility and bioavailability, as well as by the low permeability of the blood-brain barrier (BBB). In this study, a kind of transferrin-modified Ost liposomes (Tf-Ost-Lip) was constructed, which could improve the bioavailability and enhance brain targeting.

GGP modified daunorubicin plus dioscin liposomes inhibit breast cancer by suppressing epithelial-mesenchymal transition.

Tumor invasion and metastasis are the nodus of anti-tumor. Epithelial cell-mesenchymal transition is widely regarded as one of the key steps in the invasion and metastasis of breast cancer. In this study, GGP modified daunorubicin plus dioscin liposomes are constructed and characterized.

Enhanced antitumour efficacy of functionalized doxorubicin plus schisandrin B co-delivery liposomes via inhibiting epithelial-mesenchymal transition.

Non-small cell lung cancer (NSCLC) is a malignant cancer characterized by easy invasion, metastasis and poor prognosis, so that conventional chemotherapy cannot inhibit its invasion and metastasis. Doxorubicin (DOX), as a broad-spectrum antitumour drug, cannot be widely used in clinic because of its poor targeting, short half-life, strong toxicity and side effects. Therefore, the aim of our study is to construct a kind of PFV modified DOX plus schisandrin B liposomes to solve the above problems, and to explore its potential mechanism of inhibiting NSCLC invasion and metastasis.

RPV-modified epirubicin and dioscin co-delivery liposomes suppress non-small cell lung cancer growth by limiting nutrition supply.

Chemotherapy for non-small cell lung cancer (NSCLC) is far from satisfactory, mainly due to poor targeting of antitumor drugs and self-adaptations of the tumors. Angiogenesis, vasculogenic mimicry (VM) channels, migration, and invasion are the main ways for tumors to obtain nutrition. Herein, RPV-modified epirubicin and dioscin co-delivery liposomes were successfully prepared.

Combination of targeted daunorubicin liposomes and targeted emodin liposomes for treatment of invasive breast cancer.

Conventional treatment fails to completely eliminate highly invasive breast cancer cells, and most surviving breast cancer cells tend to reproliferate and metastasize by forming vasculogenic mimicry (VM) channels. Thus, a type of targeted liposomes was developed by modification with arginine-glycine-aspartic acid (RGD) to encapsulate daunorubicin and emodin separately. A combination of the two targeted liposomes was then developed to destroy VM channels and inhibit tumour metastasis.

Development of R modified epirubicin-dihydroartemisinin liposomes for treatment of non-small-cell lung cancer.

Presently, there are no few anticancer drugs that have been used clinically due to their poor targeting ability, short half-life period, non-selective distributions, generation of vasculogenic mimicry (VM) channels, high metastasis, and high recurrence rate. This study aimed to explore the effects of R modified epirubicin-dihydroartemisinin liposomes that could target non-small-cell lung cancer (NSCLC) cells, destroy VM channels, inhibit tumor metastasis, and explain the possible underlying mechanism. In vitro assays indicated that R modified epirubicin-dihydroartemisinin liposomes with ideal physicochemical characteristics could exhibit not only powerful cytotoxicity on A549 cells, but also the effective suppression of VM channels and tumor metastasis.

Vinorelbine cationic liposomes modified with wheat germ agglutinin for inhibiting tumor metastasis in treatment of brain glioma.

Glioma is the most common primary malignant brain tumor with a poor prognosis. The application of chemotherapeutic drugs is limited due to the existence of blood-brain barrier and serious side effects. Liposomes have been proven to be a stable and useful drug delivery system for tumors.

Functional paclitaxel plus honokiol micelles destroying tumour metastasis in treatment of non-small-cell lung cancer.

Treatment effect of chemotherapy for aggressive non-small-cell lung cancer (NSCLC) is usually unsatisfactory for non-selective distributions of anticancer drugs, generation of vasculogenic mimicry (VM) channels, high metastasis and recurrence rate. Therefore, we developed a kind of dequalinium (DQA) modified paclitaxel plus honokiol micelles in this study to destroy VM channels and inhibit tumour metastasis. In vitro assays indicated that the targeting paclitaxel micelles with ideal physicochemical characteristics could exhibit not only the powerful cytotoxicity on Lewis lung tumour (LLT) cells but also the effective suppression on VM channels and tumour metastasis.

Development of functional docetaxel nanomicelles for treatment of brain glioma.

The efficacy of anticancer drugs is rather limited in the treatment of brain glioma due to the hindrance of the blood-brain barrier (BBB). Herein, we reported an easy formulation of functional docetaxel nanomicelles for the treatment of brain glioma using a graft copolymer soluplus as basic material through dual-modifications with a glucose-lipid derivative and a dequalinium-lipid derivative. The studies were performed on brain glioma U87MG cells, in vitro BBB models and brain glioma-bearing nude mice.

Octreotide-modified liposomes containing daunorubicin and dihydroartemisinin for treatment of invasive breast cancer.

Tumor invasion is considered a major promoter in the initiation of tumor metastasis, which is supposed to cause most cancer-related deaths. In the present study, octreotide (OCT)-modified daunorubicin plus dihydroartemisinin liposomes were developed and characterized. Evaluations were undertaken on breast cancer MDA-MB-435S cells and MDA-MB-435S xenografts nude mice.

Hyaluronic acid modified daunorubicin plus honokiol cationic liposomes for the treatment of breast cancer along with the elimination vasculogenic mimicry channels.

Background: Breast cancer is an alarming global public health problem and a main cause of cancer-related death in women. Systemic chemotherapy is the most widely used treatment for breast cancer. However, current chemotherapy treatments are far from desirable due to poor targeting specificity, severe side effects and vasculogenic mimicry (VM).

Application of multifunctional targeting epirubicin liposomes in the treatment of non-small-cell lung cancer.

Chemotherapy for aggressive non-small-cell lung cancer (NSCLC) usually results in a poor prognosis due to tumor metastasis, vasculogenic mimicry (VM) channels, limited killing of tumor cells, and severe systemic toxicity. Herein, we developed a kind of multifunctional targeting epirubicin liposomes to enhance antitumor efficacy for NSCLC. In the liposomes, octreotide was modified on liposomal surface for obtaining a receptor-mediated targeting effect, and honokiol was incorporated into the lipid bilayer for inhibiting tumor metastasis and eliminating VM channels.

Efficacy in Treating Lung Metastasis of Invasive Breast Cancer with Functional Vincristine Plus Dasatinib Liposomes.

Background: The metastasis of breast cancer is the leading cause of death, while lung metastasis is a major clinical phenomenon in patients with invasive breast cancer. The current treatment option comprising surgery, radiation, and standard chemotherapy cannot achieve a satisfactory effect on the treatment of lung metastasis of breast cancer. In this study, we report the potential of preventing lung metastasis of invasive breast cancer using the newly developed functional vincristine plus dasatinib liposomes.

Lipid vesicles containing transferrin receptor binding peptide TfR-T and octa-arginine conjugate stearyl-R efficiently treat brain glioma along with glioma stem cells.

Surgery and radiotherapy cannot fully remove brain glioma; thus, chemotherapy continues to play an important role in treatment of this illness. However, because of the restriction of the blood-brain barrier (BBB) and the regeneration of glioma stem cells, post-chemotherapy relapse usually occurs. Here, we report a potential solution to these issues that involves a type of novel multifunctional vinblastine liposomes equipped with transferrin receptor binding peptide TfR-T and octa-arginine conjugate stearyl-R.

Antitumor efficacy of Lf modified daunorubicin plus honokiol liposomes in treatment of brain glioma.

Malignant brain glioma is the most common and aggressive type of primary intracranial neoplasm. Regular chemotherapy cannot eradicate brain glioma cells and the residual glioma cells could form vasculogenic mimicry (VM) channels under hypoxic conditions to provide nutrients for tumor cell invasion. In addition, the existence of the blood-brain barrier (BBB) restricts most antitumor drugs into brain glioma.

PTD modified paclitaxel anti-resistant liposomes for treatment of drug-resistant non-small cell lung cancer.

Context: Non-small cell lung carcinoma (NSCLC) is a type of epithelial lung cancer that accounts for approximately 80-85% of lung carcinoma cases. Chemotherapy for the NSCLC is unsatisfactory due to multidrug resistance, nonselectively distributions and the accompanying side effects.

Objective: The objective of this study was to develop a kind of PTD modified paclitaxel anti-resistant liposomes to overcome these chemotherapy limitations.

Dual-functional drug liposomes in treatment of resistant cancers.

Efficacy of regular chemotherapy is significantly hampered by multidrug resistance (MDR) and severe systemic toxicity. The reduced toxicity has been evidenced after administration of drug liposomes, consisting of the first generation of regular drug liposomes, the second generation of long-circulation drug liposomes, and the third generation of targeting drug liposomes. However, MDR of cancers remains as an unsolved issue.

Construction of Functional Targeting Daunorubicin Liposomes Used for Eliminating Brain Glioma and Glioma Stem Cells.

The highly infiltrative nature of brain glioma makes total surgical removal of cancerous cells virtually impossible. Regular chemotherapy plays an important role in eradicating the residual cancer cells but is ineffective in treating brain glioma due to the hindrance of drug penetration into the tumor site by the blood brain barrier (BBB) and the regeneration of cancer cells by glioma stem cells (GSCs). In this study, functional targeting daunorubicin liposomes were developed by modifying the liposomes with distearoylphosphatidylethanolamine polyethylene glycol-polyethylenimine (DSPE-PEG2000PEI600 and a lipid-glucose derivative (DSPE-PEG2000-GLU).

Destruction of vasculogenic mimicry channels by targeting epirubicin plus celecoxib liposomes in treatment of brain glioma.

The efficacy of chemotherapy for brain glioma is restricted by the blood-brain barrier (BBB), and surgery or radiotherapy cannot eliminate the glioma cells because of their unique location. Residual brain glioma cells can form vasculogenic mimicry (VM) channels that can cause a recurrence of brain glioma. In the present study, targeting liposomes incorporating epirubicin and celecoxib were prepared and used for the treatment of brain glioma, along with the destruction of their VM channels.
