The overexpression of ATP-binding cassette (ABC) transporters is the main cause of cancer multidrug resistance (MDR), which leads to chemotherapy failure. Uncaria alkaloids are the major active components isolated from uncaria, which is a common Chinese herbal medicine. In this study, the MDR-reversal activities of uncaria alkaloids, including rhynchophylline, isorhynchophylline, corynoxeine, isocorynoxeine (Icory), hirsutine and hirsuteine, were screened; they all exhibited potent reversal efficacy when combined with doxorubicin...

REVIEW
Ravin Ratan, Shreyaskumar R Patel
Trabectedin and eribulin are two agents that have been recently approved for the treatment of specific soft tissue sarcoma subtypes. They have proved to be a much-needed line of additional treatment for patients with these rare tumors, but their activity remains admittedly modest in most cases. Further exploitation of these novel agents is likely to require a more granular understanding of the salient mechanisms of action. For example, if as some studies suggest, eribulin derives its benefit from restructuring of tumor vasculature to improve efficacy of subsequent lines of therapy, then patients may benefit from its use earlier in the treatment pathway...

This study evaluated the midterm delivery of doxorubicin in liver specimens from patients (N = 4) with hepatocellular carcinoma treated with drug-eluting embolic (DEE) transarterial chemoembolization. The patients had surgical resection 57, 79, 80 and 105 days after doxorubicin DEE chemoembolization. Doxorubicin concentrations inside embolic particles and in surrounding tissues were assessed by infrared microspectroscopy and microspectrofluorimetry, respectively. Embolic particles still contained doxorubicin and provided sustained drug delivery within targeted tissues 80 days after chemoembolization...

BACKGROUND: The addition of rituximab (R) to CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) -like therapy has improved survival in primary mediastinal B-cell lymphoma (PMBCL) patients. However, these results were obtained in young low risk patients and a reevaluation in an unselected patient cohort is warranted. METHODS: In this study, we analyzed 80 PMBCL patients treated with a CHOP-based regimen with and without rituximab. RESULTS: In the non-rituximab cohort 10-year progression free survival (PFS) was 67% and 10-year overall survival (OS) was 72% versus a PFS of 95% and a OS of 92% in the rituximab group, PFS P = 0...

The study was to develop poly-γ-glutamic acid (γ-PGA)-coated Doxorubicin (Dox) lipoplexes that enhance the antitumor activity against liver tumors. γ-PGA-coated lipoplexes were performed by electrostatistically attracting to the surface of cationic charge liposomes with anionic γ-PGA. With the increasing of γ-PGA concentration, the particle size of γ-PGA-coated Dox lipoplexes slightly increased, the zeta potential from positive shifted to negative, and the entrapment efficiency (EE) were no significant change...

Terpolymers of poly (Lysine-co-N, N-Bis (acryloyl) cystamine-co-β-Phenethylamine) (PLBP) were synthesized in one-pot by Michael addition terpolymerization. The terpolymers self-assembled into nano-sized spherical micelles (84-123nm) with narrow distributions. The surface charge of the nanomicelles (NMs) was depended on solution's pH and showed negative values under physiological conditions (pH7.4), which was beneficial for long circulation without non-specific protein adsorption. Doxorubicin (DOX) was effectively loaded into the NMs for controlled release...

Standard clinical care for breast cancer includes lumpectomy followed by localized radiotherapy or chemotherapy. However, both therapies cause loss of normal, healthy tissue in addition to tumor tissue, leading to undesirable side effects. In this study, we found that low dose and prolonged treatment with anticancer drug doxorubicin (DOX) can completely eliminate MDA-MB-231 breast cancer cells with low cytotoxicity to NIH 3T3 fibroblasts. We further developed a novel biomaterial-based drug delivery system for controlled and sustained release of low doses of DOX based on self-assembled dextran sulfate (DS)-DOX complexes...

A thin film of poly-arginine fabricated on glassy carbon electrode by one step electrodeposition method is applied for detection of doxorubicin hydrochloride in whole blood, cell lysate, and untreated-plasma samples. Cyclic voltammetry results indicated that the doxorubicin is oxidized via two electrons and two protons at physiological pH (pH=7.4) using poly-arginine thin film modified glassy carbon. More importantly, electrostatic repulsion takes place between the prepared polymer film-modified electrode and selected drug resulting in the signal amplification on oxidation of doxorubicin and lowering its over potential and thereby selective detection of doxorubicin in real samples...

Bone substitute materials with a controlled drug release ability can fill cavities caused by the resection of bone tumours and thereby combat any leftover bone cancer cells. The combined release of different cytostatics seems to enhance their toxicity. In this study, calcium phosphate beads and matrix scaffolds are combined for a long-term co-delivery of cis-diamminedichloroplatinum (cisplatin, CDDP) and doxorubicin hydrochloride (DOX) as clinical relevant model drugs. Tricalcium phosphate/alginate beads as additional drug carrier are produced by droplet extrusion with ionotropic gelation and incorporated in scaffold matrix by freeze gelation without sintering...

Folate receptors (FR) have been well recognized as a marker to target nano-sized carriers for cancer diagnosis and therapy. In contrast, influx transport systems (e.g. GLUT transporters) that transport essential amino acids and nutrients to cancer cells have not been exploited much for targeted delivery. In this study, folic acid- or n-acetyl glucosamine- functionalized mesoporous silica nanoparticles loaded with doxorubicin (DOX-FA-MSNPs or DOX-NAG-MSNPs) were prepared, characterized and compared for targeting along with cytotoxicity towards MCF-7 and MDA-MB-231 human breast cancer cells...

Conventional organic and inorganic drug nanocarriers suffer from serious drawbacks, such as low drug-storage capacity and uncontrolled release. Moreover, multidrug resistance (MDR) has been one of the primary causes leading to chemotherapy failure for cancers. The main reason of MDR is the overexpressed active efflux transporters such as P-glycoprotein. Here, zeolitic imidazolate framework ZIF-8, as one of the biocompatible metal organic frameworks (MOFs), is reported for the first time as the multidrug carrier to realize the efficient co-delivery of verapamil hydrochloride (VER) as the P-glycoprotein inhibitor as well as doxorubicin hydrochloride (DOX) as an anticancer drug to overcome the MDR in addition to realizing the active targeted ability for an efficient anticancer effect...
