Abstract The conventional methods of treating cancer with chemo- and radiotherapy present plenty of serious problems, such as low therapeutic index and high systemic toxicity. The advanced cancer treatment strategies utilize nanoformulations of drugs that can enter a tumor due to the enhanced permeability and retention (EPR) effect. However, EPR fails in the treatment of several human diseases. Mainstream biomedical studies are focused on creating the drugs that would enter the tumor with higher effectiveness and require smaller doses for administration. A two-stage drug delivery system is an encouraging alternative solution. At first, the primary, non-toxic targeting module is delivered to the tumor cells, followed by injection of the second complementary targeting module at a considerably lower dose, thus decreasing systemic toxicity. To meet the challenge, we have developed a two-stage drug delivery system (DDS), mediated by the high-affinity binding of the Barnase*Barstar protein pair. Barnase and Barstar act as lego bricks linking the first and the second modules on the surface of the cancer cell. Barnase (12 kDa) is a natural ribonuclease from Bacillus amyloliquefaciens, while Barstar (10 kDa) is its natural inhibitor. The Barnase*Barstar is one of the strongest known protein*protein complexes with Kaff = 1014 M−1 exhibiting extraordinarily stability in severe conditions. Artificial scaffold polypeptide DARPin9_29 genetically fused with Barstar served is a first module of the developed two-step DDS. DARPin9_29 (14 kDa) specifically recognizes the tumor marker HER2 overexpressed on human breast cancer cells. As a second module, a therapeutic nano-cargo was developed based on fluorescent polymer PLGA nanoparticles loaded with diagnostic Nile Blue dye and the chemotherapeutic drug doxorubicin. This nano-PLGA structure was covalently coupled to Barnase. We showed two-stage efficient labeling of HER2-overexpressing cancer cells using the first non-toxic module DARPin9_29-Barstar and the second toxic nano-module PLGA-Barnase. We demonstrated the doxorubicin-induced cytotoxicity of this two-step DDS based on polymer nanoparticles and proteinaceous Barnase-Barstar interface and showed more than 10-fold therapeutic dose reduction versus free doxorubicin. We believe that the developed two-step DDS based on PLGA nano-cargo and protein interface will promote the creation of new-generation cancer treatment strategies.

Carbon nanotubes, which are elongated fullerenes, resemble graphite sheets wrapped into cylinders with a high length-to-width ratio (few nm in diameter and up to 1 mm in length). Carbon nanotubes are molecular-scale tubes of graphitic carbon with outstanding properties. Carbon nanotubes have drawn great interest and attraction in the field of novel drug delivery system. Nanomedicines can target, diagnose, monitor and treat cancerous cell also. The small nanoscale dimension and astonishing properties make them a distinctive carrier with a wide range of promising applications. These cylindrical carbon molecules have novel properties that make them potentially useful in many applications in nanotechnology. The various nano-size carrier systems are available for biotechnological applications including the drug delivery. Carbon nanotubes are typically used for bioactive delivery due to their some unique outstanding properties. Carbon nanotubes drug delivery system opens up new potential and possibilities over nanoparticles, dendrimers, liposomes etc. for biomedical applications and new drug delivery. In last few years, Carbon nanotubes (CNTs) have shown unexpected advantages in the field of cancer treatment and drug delivery systems. Present review article discuss in brief about the methods of synthesis, with purification as well as sorting techniques for giving different grades to different types of CNTs and biomedical applications.

Anti Cancer

: Cancer still represents a leading threat to human health worldwide. The effective usage of anti-cancer drugs can reduce patients’ clinical symptoms and extend the life span. Current anti-cancer strategies include chemotherapy, traditional Chinese medicine, biopharmaceuticals, and the latest targeted therapy. However, due to the complexity and heterogeneity of tumors, serious side effects may result from the direct use of anti-cancer drugs. Besides, the current therapeutic strategies failed to effectively alleviate metastasized tumors. Recently, an ultrasound-mediated nano-drug delivery system has become an increasingly important treatment strategy. Due to its ability to enhance efficacy and reduce toxic side effects, it has become a research hotspot in the field of biomedicine. In this review, we introduced the latest research progress of the ultrasound-responsive nano-drug delivery systems and the possible mechanisms of ultrasound acting on the carrier to change the structure or conformation as well as to realize the controlled release. In addition, the progress in ultrasound responsive nano-drug delivery systems will also be briefly summarized.

Abstract Background Nano-drug delivery systems show considerable promise for effective cancer therapy. Polymeric micelles have attracted extensive attention as practical nanocarriers for target drug delivery and controlled drug delivery system, however, the distribution of micelles and the release of the drug are difficult to trace in cancer cells. Therefore, the construction of a redox-sensitive multifunctional drug delivery system for intelligent release of anticancer drugs and simultaneous diagnostic imaging and therapy remains an attractive research subject. Results To construct a smart drug delivery system for simultaneous imaging and cancer chemotherapy, mPEG-ss-Tripp was prepared and self-assembled into redox-sensitive polymeric micelles with a diameter of 105 nm that were easily detected within cells using confocal laser scanning microscopy based on aggregation-induced emission. Doxorubicin-loaded micelles rapidly released the drug intracellularly when GSH reduced the disulfide bond. The drug-loaded micelles inhibited tumor xenografts in mice, while this efficacy was lower without the GSH-responsive disulfide bridge. These results establish an innovative multi-functional polymeric micelle for intracellular imaging and redox-triggered drug deliver to cancer cells. Conclusions A novel redox-sensitive drug delivery system with AIE property was constructed for simultaneous cellular imaging and intelligent drug delivery and release. This smart drug delivery system opens up new possibilities for multifunctional drug delivery systems.

Skin cancer, one of the most prevalent cancers worldwide, has demonstrated an alarming increase in prevalence and mortality. Hence, it is a public health issue and a high burden of disease, contributing to the economic burden in its treatment. There are multiple treatment options available for skin cancer, ranging from chemotherapy to surgery. However, these conventional treatment modalities possess several limitations, urging the need for the development of an effective and safe treatment for skin cancer that could provide targeted drug delivery and site-specific tumor penetration and minimize unwanted systemic toxicity. Therefore, it is vital to understand the critical biological barriers involved in skin cancer therapeutics for the optimal development of the formulations. Various nanocarriers for targeted delivery of chemotherapeutic drugs have been developed and extensively studied to overcome the limitations faced by topical conventional dosage forms. A site-specific vesicular drug delivery system appears to be an attractive strategy in topical drug delivery for the treatment of skin malignancies. In this review, vesicular drug delivery systems, including liposomes, niosomes, ethosomes, and transfersomes in developing novel drug delivery for skin cancer therapeutics, are discussed. Firstly, the prevalence statistics, current treatments, and limitations of convention dosage form for skin cancer treatment are discussed. Then, the common type of nanocarriers involved in the research for skin cancer treatment are summarized. Lastly, the utilization of vesicular drug delivery systems in delivering chemotherapeutics is reviewed and discussed, along with their beneficial aspects over other nanocarriers, safety concerns, and clinical aspects against skin cancer treatment.
