Drug Repurposing and Repositioning: Workshop Summary
by Sarah H. BeachyDrug development can be time-consuming and expensive. Recent estimates suggest that, on average, it takes 10 years and at least $1 billion to bring a drug to market. Given the time and expense of developing drugs de novo, pharmaceutical companies have become increasingly interested in finding new uses for existing drugs - a process referred to as drug repurposing or repositioning. Historically, drug repurposing has been largely an unintentional, serendipitous process that took place when a drug was found to have an offtarget effect or a previously unrecognized on-target effect that could be used for identifying a new indication. Perhaps the most recognizable example of such a successful repositioning effort is sildenafil. Originally developed as an anti-hypertensive, sildenafil, marketed as Viagra and under other trade names, has been repurposed for the treatment of erectile dysfunction and pulmonary arterial hypertension. Viagra generated more than $2 billion worldwide in 2012 and has recently been studied for the treatment of heart failure. Given the widespread interest in drug repurposing, the Roundtable on Translating Genomic-Based Research for Health of the Institute of Medicine hosted a workshop on June 24, 2013, in Washington, DC, to assess the current landscape of drug repurposing activities in industry, academia, and government. Stakeholders, including government officials, pharmaceutical company representatives, academic researchers, regulators, funders, and patients, were invited to present their perspectives and to participate in workshop discussions. Drug Repurposing and Repositioning is the summary of that workshop. This report examines enabling tools and technology for drug repurposing; evaluates the business models and economic incentives for pursuing a repurposing approach; and discusses how genomic and genetic research could be positioned to better enable a drug repurposing paradigm.

Drug Resistance in Bacteria, Fungi, Malaria, and Cancer
by Vipin Chandra Kalia Gunjan Arora Andaleeb SajidThis book is a compilation of past and recent knowledge in the field of emerging drug resistance. The book covers major aspects of drug resistance in bacteria, fungi, malaria, and cancer. Human survival on earth is constantly threatened by disease and syndrome. From the early days, the aim of research in medicine was to find therapeutic agents that can improve the quality of human life. Although humans are dependent on natural compounds from early days their dependence of drugs increased excessively in last century. The advances in chemistry and biology have helped researchers to identify the drugs that have improved treatment of many diseases. The primary factor for treatment of these diseases is dependent on the efficacy of drugs available. The development of resistance to these drugs is one of the major hindrances. Although there are number of books available on this topic, "drug resistance" biology across kingdoms has never been discussed in a coherent way.
Drug Resistance in Cancer Cells
by Susan E. Bates Zahid H. Siddik Kapil MehtaThe inability of cancer drugs to destroy metastatic tumors is the major reason why cancer therapy fails. Even though the process of drug design has become exceedingly sophisticated in recent years, there is not a single drug available that is 100% effective against metastatic cancer. Resistance to treatment with anticancer drugs results from a variety of factors including individual variations in patients and somatic/genetic differences in tumors, even those from tissue of origin. Although it is a generally accepted fact that the majority of cancers arise from a single precursor cell, it is naïve to consider that tumor is a collection of genetically identical cells. Genetic instability and accumulation of mutations are important hallmarks of cancer cells. This means that dividing cancer cells are able to acquire genetic and epigenetic changes that will favor their malignant phenotype. In view of this, it is fair to say that the cells in a given tumor may be similar but not identical. Therefore, when treated with a drug, the sensitive cells in a tumor succumb to the toxic effects of the drug, and resistant cells continue to survive and multiply. The tumor, which re-grows from these residual resistant cells, is not sensitive to the original drug.
Drug Resistance in Cancer: Mechanisms and Strategies
by Sameer Ullah Khan Fayaz MalikThis book tries to emphasize the mechanisms associated with the resistance towards various anti-cancer therapies The focus has been given to the role of cancer stem cells, immune cells, and the multiway impact of tumor microenvironment in drug resistance.

Each chapter of the book has elaborated on these aspects that are exclusively or mutually driving the therapeutic non-responsiveness towards various current clinical candidates. In addition to that the book has also discussed novel strategies to overcome the therapeutic challenge by employing combinatorial therapies that can prove to be useful and effective. Overall the book reflects on the current treatment challenges, futuristic strategies and new research initiatives that explore novel treatment options.
Drug Resistance in Leishmania Parasites
by Maritza Padrón-Nieves Emilia Diaz Alicia Ponte-SucreOne of the main problems concerning therapeutic tools for the treatment of parasitic diseases, including leishmaniasis, is that some field parasites are naturally resistant to the classical drugs; additionally, current therapies may select parasites prone to be resistant to the applied drugs.
