In recent decades, several types of anticancer drugs that inhibit cancer cell growth and cause cell death have been developed for chemotherapeutic application. However, these agents are usually associated with side effects resulting from nonspecific delivery, which may induce cytotoxicity in healthy cells. To reduce the nonspecific delivery issue, nanoparticles have been successfully used for the delivery of anticancer drugs to specific target sites. In this study, a functional polymeric lipid, PEG-GLFG-K(C16)2 (PEG-GLFG, polyethylene glycol-Gly-Leu-Phe-Gly-Lys(C16)2), was synthesized to enable controlled anticancer drug delivery using cathepsin B enzyme-responsive liposomes. The liposomes composed of PEG-GLFG/DOTAP (1,2-dioleoyl-3-trimethylammonium-propane (chloride salt))/DPPC (dipalmitoylphosphatidylcholine)/cholesterol were prepared and characterized at various ratios. The GLFG liposomes formed were stable liposomes and were degraded when acted upon by cathepsin B enzyme. Doxorubicin (Dox) loaded GLFG liposomes (GLFG/Dox) were observed to exert an effective anticancer effect on Hep G2 cells in vitro and inhibit cancer cell proliferation in a zebrafish model.

Liposomes quite recently have turned from a model of biological membranes into an object of extensive research and practical use. The versatile traits of liposomal formulation allow its' universal implementation, especially in cancer chemotherapy. The advantages of liposomal use as a carrier of an anticancer drug for its targeted selective accumulation are discussed in this article. This article contains description of new types of liposomes, differing in contents and use, such as: simple, sterically stabilized, targeted (immunoliposomes),cationic, sensitive to physical and chemical stimuli. The characteristics of liposomal systems of anticancer drug delivery designed at Blokhin Russian Oncological Scientific Centre is given in the article.

Biological Studies

Background: Scientists have extensively investigated curcumin, yielding many publications on treatments of cancer. Numerous derivatives of curcumin were synthesized, evaluated for their anti-oxidant and free-radical scavenging, SAR, ADME properties and tested in anticancer applications. Objective: We decided to exploit curcumin as a bioactive core platform for carrying anticancer drugs, which likely possesses a carboxyl moiety for potential linkage to the carrier for drug delivery. Methods: The goal of this work is to develop biolabile multifunctional curcumin platforms towards anticancer drug delivery, including determination of drug release profiling in hydrolytic media, in vitro cytotoxicity, antioxidant properties and blockage of relevant cell survival pathways. Results: We report on a facile synthesis of the bioactive multifunctional curcumin-based platforms linked to a variety of anticancer drugs like amonafide and chlorambucil, and release of the drugs in a hydrolytic environment. The leading curcumin-based platform has presented antioxidant activity similar to curcumin, but with much more potent cytotoxicity in vitro in agreement with the augmented blockage of the NF-kB cell survival pathway. Conclusion: The approach presented here may prove beneficial for bioactive curcumin-based delivery applications where multiple drug delivery is required in a consecutive and controlled mode.

Anticancer Drug Delivery

To date, chemotherapy, the main treatment for malignant tumors, still fails to provide ideal therapeutic efficacy, which is deeply rooted in various physiological barriers, either temporal or spatial, to the delivering of anticancer drugs to solid tumor sites during chemotherapy. In the meantime, the therapeutic efficacy of anticancer drugs is affected by inherent cancer characteristics, drug transport, cellular uptake and other complex interactions. Recently, advances have been constantly achieved on nanoscale drug delivery systems (NDDSs) for anticancer drug delivery, driven by their excellent stability and effectiveness in improving water solubility of anticancer drugs, prolonging systemic circulation time, reducing side effects and improving anticancer effects. This paper presents an overview of the current research status and challenges in applying NDDSs to anticancer drug delivery.
