Combinatorial technology for the generation of molecular diversity has evolved as an integrated component in accelerated drug discovery process. During the emerging days of combinatorial chemistry, solid-phase organic synthesis has been the leading strategy for the production of large libraries for lead discovery. As combinatorial techniques for the library synthesis has evolved, solution-phase synthesis of smaller, target Read More

The development of therapies which are selective for tumor tissues is one of the most important goals in anticancer research. Within this framework photochemotherapy can be considered a very promising approach. Its therapeutic effectiveness depends on two connected factors: drug and light. The drug (photosensitizer) is able to exert an antiproliferative effect only after interaction with suitable light. Both the pho Read More

Farnesyl protein transferase (FPT) inhibition is an interesting and promising approach to non-cytotoxic anticancer therapy. Research in this area has resulted in several orally active compounds that are currently in clinical evaluation. This review focuses on FPT inhibitors in clinical trials and concentrates on the benzocycloheptapyridine class, with details on the discovery and development of SCH 66336, currently in Phase II clinical trials.

The development of farnesyltransferase inhibitors (FTIs) has been one of the most active areas of anticancer drug development for the past ten years. This review presents a general overview of the developments in this area, along with a critical appraisal of the anticancer activity of FTIs. A historical survey of the protein prenylation field is given, in particular to emphasize the key role played by the Ras oncoprotein in driving Read More

Natural Products have long been a fertile source of cure for cancer, which is projected to become the major causes of death in this century. However, there is a continuing need for development of new anticancer drugs, drug combinations and chemotherapy strategies, by methodical and scientific exploration of enormous pool of synthetic, biological and natural products.There are at least 250,000 species of plants out of w Read More

As a result of substantial advances in recent cancer biology, cell cycle regulation in the G1 phase has attracted a great deal of attention as a promising target for the research and treatment of cancer. Many of the important genes associated with G1 regulation have been shown to play a key role in proliferation, differentiation and oncogenic transformation and programmed cell death (apoptosis). Currently, a variety of cyt Read More

Inhibitors of histone deacetylase (HDAC) are an emerging class of anticancer agents. They induce hyperacetylation in chromatin usually resulting in activation of certain genes. They induce terminal cell differentiation and / or apoptosis in cancer cells. Histone deacetylase activity is recruited by co-repressor proteins to certain regions of the chromatin and aberrant histone acetylation caused by that recruitment is responsible for Read More

Polycyclic aromatic hydrocarbons (PAH) are considered potentially carcinogenic. Substituted PAH derivatives, in contrast, may serve as anticancer agents, and as chemotherapeutics. This article presents a review of their use. Particular emphasis is placed on the synthesis of these new compounds, electrophilic substitution reactions and novel synthetic methodologies developed in our laboratory. Based on numerous rep Read More
