Anti-Cancer Agents in Medicinal Chemistry (Formerly Current Medicinal Chemistry - Anti-Cancer Agents) - Volume 12, Issue 1, 2012

The journal Anti-Cancer Agents in Medicinal Chemistry has recently received its first impact factor of 3.144. I am sure this will encourage very high quality manuscript submissions going forward. I would like to take this opportunity to thank the authors for their excellent contributions, and the reviewers and Editorial Board Members for their precious assistance. I would like also to thank Ms. Madiha Zahoor and the entire staff of Read More

G-protein and phosphorylation dependent signalling network are the major signalling pathways that control several fundamental cellular processes. Therefore understanding the biology and the molecular mechanism of these molecules allow us to identify possible drug targets. Although there has been an incredible research focus on understanding the onset and progression of cancer, the search still continues across various a Read More

Protein tyrosine phosphatases (PTPs) constitute a large family of enzymes that can exert both positive and negative effects on signaling pathways. They play dominant roles in setting the levels of intracellular phosphorylation downstream of many receptors including receptor tyrosine kinases and G protein-coupled receptors. As observed with kinases, deregulation of PTP activity can also contribute to cancer. This review will ex Read More

The Ras GTPases are the founding members of large Ras superfamily, which constitutes more than 150 of these important class of enzymes. These GTPases function as GDP-GTP-regulated binary switches that control many fundamental cellular processes. There are a number of GTPases that have been identified recently, which do not confine to this prototype termed as “atypical GTPases” but have proved to play a remarkabl Read More

One of the major challenges in achieving effective anti-cancer immunotherapy is to counteract immunological tolerance. Most tumor-associated antigens (TAAs) are sensed as self. Hence, naturally occurring tolerance towards them has to be overcome. Fortunately, there is increasing evidence that anti-tumor immune responses occur and play a crucial role in the success of well-established anti-neoplastic therapies suc Read More

Over the past decade, fragment-based drug discovery has developed significantly and has gained increasing popularity in the pharmaceutical industry as a powerful alternative and complement to traditional high-throughput screening approaches for hit identification. Fragment-based methods are capable of rapidly identifying starting points for structure-based drug design from relatively small libraries of low molecular Read More

Natural products are important sources of anti-cancer lead molecules. Many successful anti-cancer drugs are natural products or their analogues. Many more are under clinical trials. The present review focuses on chemopreventive and anti-cancer activities of polar and non-polar extracts, semi purified fractions and pure molecules from terrestrial plants of India reported between 2005 and 2010 emphasizing possible mech Read More

Besides the common issue of drug-resistance, the conventional approaches for cancer diagnostics and treatment are constantly challenged by poor selectivity and limited access to neoplastic cells, which not only lead to the dose-limiting effect on the tumor region, but also bring side-effects to healthy cells/tissues. In recent years, a novel strategy has arisen to target the vasculature of tumors for drugdelivery and molecular i Read More

Anaplastic thyroid cancer (ATC) is often incurable because it doesn't respond to radioiodine, radiotherapy or chemotherapy, and new therapeutic approaches are needed. Peroxisome proliferator-activated receptor-gamma (PPARg) gene and protein are present in ATC cells, and PPARg ligands inhibit cell proliferation, induce apoptosis, and also down regulate the invasive potential of ATC cells. Also, inhibitors of the Aurora serine/ Read More
