Drug distribution in cells is a fundamentally important, yet often overlooked, variable in drug efficacy. Many weakly basic anticancer agents accumulate extensively in the acidic lysosomes of normal cells through ion trapping. Lysosomal trapping reduces the activity of anticancer drugs, since anticancer drug targets are often localized in the cell cytosol or nucleus. Some cancer cells have defe...

Purpose: Many anthracycline anticancer drugs contain carbohydrate moieties as a part of their chemical structure. Research studies have suggested that the sugar moiety of these anthracyclines play an important role in determining the biological and pharmacological activities of the drug. The clinical application of anthracycline antibiotics, daunorubicin (DNR) and doxorubicin is limited by the ...

To explore genes that determine the sensitivity of cancer cells to anticancer drugs, we investigated using cDNA microarrays the expression of 9216 genes in 39 human cancer cell lines pharmacologically characterized on treatment with various anticancer drugs. A bioinformatical approach was then exploited to identify genes related to anticancer drug sensitivity. An integrated database of gene exp...

This study identified the actual conditions for safe anticancer drug management among nurses and the relationship between level of awareness and performance of anticancer drug safety regulations in terms of preparation, administration, and disposal. The respondents were 236 nurses working with chemotherapy in wards and outpatient clinics in five hospitals in and near Seoul. Safety regulations p...

Chloroquine (CQ) and hydroxychloroquine (HCQ) have been used to treat malaria autoimmune diseases for more than 70 years; they also immunomodulatory anticancer effects, which are linked autophagy autophagy-independent mechanisms. Herein, we review the pharmacokinetics, preclinical studies clinical trials investigating use of CQ HCQ as adjuvant agents in cancer therapy. We discuss their safety p...

Lung cancer, breast cancer and colorectal cancer are the most prevalent fatal types of cancers globally. Gallic acid (3,4,5-trihydroxybenzoic acid) is a bioactive compound found in plants and foods, such as white tea, witch hazel and it has been reported to possess anticancer, antioxidant and anti-inflammatory properties. In this study we have redesigned our previously reported anticancer nanoc...

The encapsulation of anticancer drugs in a liposome structure protects the drug during circulation and increases drug accumulation in the cancer tissue and antitumor activity while decreasing drug toxicity. This paper presents a new method of active drug loading based on a vitamin C pH/ion gradient. Formulations were characterized in terms of the following parameters: optimal external pH, time ...

Colorectal cancer is the third most common cancer world wide and has been occurred more in developing regions. The use of conventional chemotherapy agents may lead to various adverse effects. Therefore, it is required to find the potential drug for anticancer from alternative source of natural product including mangrove plants. The present study was conducted to determine the anticancer activit...

A multifunctional gold nanorod (AuNR) complex is described with potential utility for theranostic anticancer treatment. The AuNR was functionalized with cyclodextrin for encapsulation of doxorubicin, with folic acid for targeting, and with a photo-responsive dextran-azo compound for intracellular controlled drug release. The interaction of a AuNR complex with HeLa cells was facilitated via a fo...

A targeted micellar drug delivery system is developed from a biocompatible and biodegradable amphiphilic polyester, poly(Lac-OCA)-b-(poly(Tyr(alkynyl)-OCA)-g-mannose) (PLA-b-(PTA-g-mannose), that is synthesized via controlled ring-opening polymerization of O-carboxyanhydride (OCA) and highly efficient "Click" chemistry. Doxorubicin (DOX), a model lipophilic anticancer drug, can be effectively e...
