Anti-Cancer Agents in Medicinal Chemistry (Formerly Current Medicinal Chemistry - Anti-Cancer Agents) - Volume 11, Issue 10, 2011

This special issue is focused in the applications of gold derivatives as anti-cancer agents, a research area that is in growing development in the recent years. Gold complexes were already known as rheumatoid arthritis agents for a long time, but their anti-cancer capabilities are much less explored. Interestingly, this emerging research area uses very top techniques such as proteomics, fluorescence microscopy, nanochemi Read More

Gold complexes have been explored as metallodrugs with great potential applications as antitumoral agents. In particular, gold-phosphine derivatives seemed quite promising since the use of the antiarthritic auranofin drug (thiolate-Au-PEt3 complex) presented also biological activity against different cancer cells. So, different auranofin analogues have been explored within this context and for this reason, the main nu Read More

Gold compounds form an interesting class of antiproliferative agents of potential pharmacological use in cancer treatment. Indeed, a number of gold compounds, either gold(III) or gold(I), were recently described and characterised that manifested remarkable cytotoxic properties in vitro against cultured cancer cells; for some of them encouraging in vivo results were also reported toward a few relevant animal models of c Read More

Since the introduction of the monomeric orally bioavailable anti-arthritic gold compound auranofin in 1985, and the success of the platinum-based anti-cancer drugs, there has been a great deal of interest in the use of gold compounds for cancer therapy. However this early promise has not materialized into an approved drug in spite of extensive and innovative efforts in gold chemistry. Therefore, in the light of this lack of suc Read More

Well-designed photothermal nanostructures have attracted many scientists pursuing a better means to accurately diagnose cancer and assess the efficacy of treatment. Recently, gold-based nanostructures (nanoshells, nanorods and nanocages) have enabled photothermal ablation of cancer cells with near-infrared (NIR) light without damaging normal human tissues and in particular, animal studies and early clinical testing sho Read More

Over the last few decades, the study of nanotechnology has grown exponentially. Nanotechnology bridges science, engineering and technology; it continues to expand in definition as well as practice. One sub-set of nanotechnology is bionanotechnology, this will be the focus of this review. Currently, bionanotechnology is being studied and exploited for utility within medicinal imaging, diagnosis and therapy in regard to canc Read More

CORAL software (http://www.insilico.eu/coral/) has been used for modeling of carcinogenicity (logTD50) of 401 compounds, and anticancer activity (-logIC50) of 100 compounds, on the basis of quantitative structure - activity relationships (QSAR). The simplified molecular input line entry system (SMILES) was used for the representation of the molecular structures. A new additional global invariant of the molecular structure was t Read More

Tumor growth depends upon access to host blood vessels. Many steps in tumor angiogenesis have been defined including tumor cell hypoxia, tumor cell secretion of pro-angiogenic growth factors, receptor activation on host endothelium and stroma, and establishment of new blood vessels feeding the tumor mass. Inhibitors for some of these steps have been synthesized and tested clinically. While modest improvements in r Read More

AKT (or protein kinase B) and focal adhesion kinase (FAK) are two important kinases that regulate various cellular functions. Each is overexpressed and/or aberrantly activated in diverse cancers. Several small molecular inhibitors targeting either AKT or FAK are in development or in clinical trials. It is well established that FAK is an upstream regulator of AKT signaling pathway in various cancer cell lines and in xenograft tumor mod Read More
