Foreword
Drug Discovery for Neglected Diseases – Past and Present and Future
The kinetoplastid diseases – sleeping sickness, the leishmaniases, and Chagas disease – are “neglected diseases of poverty,” afflicting millions of people and collectively responsible for over 100 000 deaths per annum. No vaccines are available and current insect vector control methods and other public health measures are insufficient to eliminate them. The currently available drug therapies are far from satisfactory due to issues such as poor efficacy, toxicity, the need for hospitalization, the requirement for prolonged parenteral treatment, and high cost. This book is a timely attempt to address some of these unmet medical needs.
It is somewhat ironic that, at the beginning of the twentieth century, many of the ground-breaking developments in drug discovery were driven by economic and colonial expansion in Africa and Asia. The African trypanosome in particular was an early model for experimental chemotherapy along two main lines of investigation: synthetic dyes, and organic arsenicals and antimonials (for further details, see reviews by Williamson [1] and Steverding [2]). Indeed, the first synthetic compound to cure an infectious disease in an animal model was the dye, Trypan red (Ehrlich, 1904), which was a forerunner of suramin (1916–1920), the first effective trypanocidal drug for human African trypanosomiasis (HAT). The demonstration by Thomas and Breinl in 1905 of the trypanocidal activity in mice of atoxyl (p-aminophenylarsonic acid) formed the basis of Ehrlich's pioneering work on organic arsenicals that culminated in the development of arsphenamine (606, Salvarsan) for the treatment of syphilis (Ehrlich and Hata, 1910) and tryparsamide for the treatment of HAT (Jacobs and Heidelberger, 1919). Tryparsamide, which caused blindness in 10–20% of patients, was finally replaced by melarsoprol (Friedheim, 1949). Trivalent antimony, in the form of tartar emetic, was shown to be trypanocidal in mice (Plimmer and Thompson, 1908), but lacked efficacy in humans. However, potassium antimony tartrate was found to have some activity in the treatment of leishmaniasis (Vianna, 1912) and was the forerunner of the pentavalent antimonial drugs, sodium stibogluconate (Pentostam®) and meglumine antimonate (Glucantime®), both introduced in the 1940s. Along with the diamidine, pentamidine (1937), all of these drugs are still in use today.
From the 1950s, subsequent drug treatments have largely been discovered by serendipity through repurposing of existing drugs used for other indications. The nitrofuran, nifurtimox, and the nitroimidazole, benznidazole, used for the treatment of Chagas disease arose from research into nitro-compounds as antibacterial agents. Amphotericin B, isolated in 1953, was originally developed for the treatment of systemic mycoses, but later found use in the treatment of visceral leishmaniasis in the 1990s as the expensive, but highly efficacious liposomal formulation (AmBisome®) or as the cheaper, but more toxic amphotericin B deoxycholate. Both formulations were included in the World Health Organization's Essential Medicines List in 2009. The off-patent aminoglycoside, paromomycin, originally developed as an oral treatment for intestinal infections in the 1960s, finally gained approval as paromomycin intramuscular injection for the treatment of visceral leishmaniasis in India in 2006. Two anticancer agents, the phospholipid analog, miltefosine, registered as the first oral treatment for visceral leishmaniasis in India in 2002, and eflornithine (now in combination with oral nifurtimox as nifurtimox–eflornithine combination therapy (NECT), 2009) for the treatment of HAT caused by Trypanosoma brucei gambiense complete the woefully inadequate treatment options for these diseases. Notably, none of these newer developments have completely displaced their forerunners that were developed prior to the 1950s.
After nearly a century of research, only 10 novel chemical entities for three diseases is a singularly unimpressive output by the pharmaceutical industry. The reason for this lamentable performance is not hard to find. Poor economic return on investment by pharma is a major factor, since these are diseases of poverty. The thalidomide disaster of the late 1950s kick-started regulatory demands for greater patient safety resulting in ever-increasing development costs. Blockbuster drugs were “in;” smaller, less profitable markets were “out.” Ninety percent of research and development was aimed at 10% of the world's unmet medical need – the so-called “10–90 gap.” The drive for greater efficiency and profitability through mergers and acquisitions resulted in the loss of parasitology expertise in most pharma companies. Medicinal chemists were seduced by combinatorial chemistry without due regard for chemical space and drug-likeness. Miniaturization of chemical synthesis restricted the use of animal disease models and shifted emphasis towards target screening. Intellectual property rights were increasingly used as an obstructive, rather than an enabling tool.
At the end of the twentieth century, the situation had become so dire that a radical new approach was required. One of the most encouraging developments was the founding of “public–private partnerships” (PPPs), such as the Drugs for Neglected Diseases initiative (DNDi) and Medicines for Malaria Venture (MMV) – non-profit organizations who strive to forge drug discovery partnerships between multiple academic, biotech, and pharma partners with funding from the governmental and charitable sector [3]. PPPs were initially met with much skepticism, but by 2005, an analysis by Mary Moran and colleagues concluded that PPPs were responsible for three-quarters of an expanded research and development portfolio for neglected diseases [4]. Another important development was the publication of annotated genomes for T. brucei, L. major, and T. cruzi in 2005 [5–7]. As Barry Bloom optimistically prophesized 10 years earlier “Sequencing bacterial and parasitic pathogens . . . could buy the sequence of every virulence determinant, every protein antigen and every drug target . . . for all time” [8]. Certainly, pathogen genomes are proving to be a valuable resource for target discovery, but without a deeper understanding of parasite biology the full potential of these genomes will not be realized. About the same time as genome sequencing was getting underway, C.C. Wang threw down the gauntlet that academics needed genetic evidence of essentiality to justify their claims of the therapeutic potential of their research field [9]. This dogma has now been refined and extended to include chemical evidence of druggability, driven by a defined therapeutic product profile [10]. These challenges have encouraged some academics to move out of their traditional comfort zones to fill the early-stage drug discovery gap in translational medicine not adequately covered by the PPPs [11]. The concept of “one gene, one target, one drug” has been very much at the forefront of current academic (and industry) thinking, with structure-based design an important adjunct in this strategy. Thus, it is timely that much of this book is devoted to the identification of metabolic peculiarities in the kinetoplastids that can be chemically and genetically validated as drug targets.
However, what of the future? Experience in industry and in academia suggests that the rate of validation of new targets is failing to keep pace with the rate of attrition of currently validated targets. Despite initial promise, the target-based approach has yielded disappointing results in anti-bacterial discovery in pharma [12] and lessons need to be learned from this if we are to avoid making the same mistakes. Rapid and robust methods of genetic target validation are still needed for parasites causing visceral leishmaniasis and Chagas disease, and we need a better understanding of basic biology to understand why targets fail. Certainly, not all targets are equal from a medicinal chemistry point of view. Greater attention needs to be paid to drug likeness [13] and ligand efficiency [14] for lead selection. Screening of fragment libraries using biophysical methods should help to weed out “undruggable” targets without recourse to expensive high-throughput screens [15]. From a pharmacology perspective, cytocidal activity is much preferable to cytostatic, so biologists should address this question early in discovery. Likewise, the potential ease for resistance arising as a result of point mutations in a single-target strategy should be a research priority for biologists. Systems biology suggests that exquisitely selective, single-target compounds may exhibit lower than desired clinical efficacy compared with multitarget drugs due to the robustness of biological networks [16]. Thus, polypharmacology (network pharmacology) is undergoing a resurgence of interest. Given the paucity of validated druggable targets, phenotypic screening is undergoing a revival aided by access to large compound collections held by pharma and the development of suitable miniaturized whole-parasite screens and mammalian counter-screens. This approach has the advantage of addressing the key druggability issues of cell permeability, desirable cytocidal activity, and a suitable parasite–host selectivity window. Phenotypic screening can also identify compounds hitting non-protein targets (e.g., amphotericin B) or compounds that act as pro-drugs (e.g., nitroimidazoles). However, the future challenge will be to identify the often complex mode(s) of action of such phenotypic hits (target deconvolution), and to use modern technologies to improve the potency and selectivity of these molecules [17]. Finally, we should ask ourselves whether our compound collections are too “clean” in terms of chemical reactivity. After all, arsenicals, antimonials, nitro-drugs, and eflornithine all undergo reaction with one or more targets, and about one-quarter of all drugs that inhibit enzymes are essentially irreversible reactions [18].
I believe that there is every cause for optimism in the battle against neglected diseases. As long as “donor fatigue” does not set in, and industry continues to engage in a positive and productive manner with academia, future prospects look better than at any time in history. However, we should all remember the dictum by Sir James Black “to first purge your project of wishful thinking” if we are to succeed!

COST – the acronym for European Cooperation in Science and Technology – is the oldest and widest European intergovernmental network for cooperation in research. Established by the Ministerial Conference in November 1971, COST is presently used by the scientific communities of 36 European countries to cooperate in common research projects supported by national funds.
The funds provided by COST – less than 1% of the total value of the projects – support the COST cooperation networks (COST Actions) through which, with EUR 30 million per year, more than 30 000 European scientists are involved in research having a total value which exceeds EUR 2 billion per year. This is the financial worth of the European added value which COST achieves.
A “bottom-up approach” (the initiative of launching a COST Action comes from the European scientists themselves), “à la carte participation” (only countries interested in the Action participate), “equality of access” (participation is open also to the scientific communities of countries not belonging to the European Union), and “flexible structure” (easy implementation and light management of the research initiatives) are the main characteristics of COST.
As precursor of advanced multidisciplinary research COST has a very important role for the realization of the European Research Area (ERA) anticipating and complementing the activities of the Framework Programmes, constituting a “bridge” towards the scientific communities of emerging countries, increasing the mobility of researchers across Europe, and fostering the establishment of “Networks of Excellence” in many key scientific domains such as: Biomedicine and Molecular Biosciences; Food and Agriculture; Forests, their Products and Services; Materials, Physical, and Nanosciences; Chemistry and Molecular Sciences and Technologies; Earth System Science and Environmental Management; Information and Communication Technologies; Transport and Urban Development; Individuals, Societies, Cultures, and Health. It covers basic and more applied research and also addresses issues of a prenormative nature or of societal importance.

Preface
Infections caused by parasites of the trypanosomatid family are considered to belong to the most neglected diseases. They comprise the African sleeping sickness (Trypanosoma brucei rhodesiense, T. brucei gambiense), the Chagas' disease in Latin America (T. cruzi), the black fever or Kala-Azar (Leishmania donovani) and other forms of Leishmaniasis (various Leishmania species). They affect about 30 million of people and account for half a million of fatalities per year. Trypanosomatids also cause substantial economic losses by affecting life stock (T. brucei brucei, T. congolense, T. evansi). Available treatments of the diseases are unsatisfactory in terms of safety and efficacy. Industrial commitments to meet the therapeutic needs remain limited because of unfavourable economic perspectives for drugs acting on diseases that prevail in countries with poor socio-economic conditions. In fact, currently used drugs are overwhelmingly those developed many decades ago when the ‘Western World’ had still to be concerned about the health of administrators and soldiers in their tropical colonies.
The present book originates from an interdisciplinary network of academic and industrial researchers devoted to the development of “new drugs for neglected diseases”. The initiative was sponsored by the European Union (COST Action CM0801) and in the beginnings was largely restricted to Europe. Over the four years of its operation, however, the exchange of experience and cooperative projects expanded far beyond its geographical basis, particularly by integrating countries in Latin America, Africa and Asia where the diseases are endemic. The progress achieved by this network is reflected in many of the contributions to the book. The editors, however, took care not just to present a ‘progress report’ but the state-of-the-art in the entire field of drug discovery for trypanosomatid diseases, as reviewed by leading scientists from all over the world. It is hoped that the compiled knowledge will become instrumental to shorten the time from basic discoveries to the urgently needed new drugs for the neglected diseases.
The editor's heartfelt thanks go to the contributing authors for their excellent work, to the series editor Paul M. Selzer for his constructive advice, and to the COST Office in Brussels for financial support.
