Drug Discovery in Africa


Book Description

Drug discovery originating in Africa has the potential to provide significantly improved treatment of endemic diseases such as malaria, tuberculosis and HIV/AIDS. This book critically reviews the current status of drug discovery research and development in Africa, for diseases that are a major threat to the health of people living in Africa. Compiled by leading African and international experts, this book presents the science and strategies of modern drug discovery. It explores how the use of natural products and traditional medicines can benefit from conventional drug discovery approaches, and proposes solutions to current technological, infrastructural, human resources, and economic challenges, which are presented when attempting to engage in full-scale drug discovery. Topics addressed are varied; from African medicinal plants to marine bioprospecting, pharmacogenetics and the use of nanotechnology. This book brings together for the first time a collection of strategies and techniques that need to be considered when developing drugs in an African setting. It is an unprecedented and truly international effort, highlighting the remarkable effort made so far in the area of drug discovery research by African scientists, and scientists from other parts of the world working on African health problems.




Synthesizing Hope


Book Description

Synthesizing Hope opens up the material and social world of pharmaceuticals by focusing on an unexpected place: iThemba Pharmaceuticals. Founded in 2009 with a name taken from the Zulu word for hope, the small South African startup with an elite international scientific board was tasked with drug discovery for tuberculosis, HIV, and malaria. Anne Pollock uses this company as an entry point for exploring how the location of scientific knowledge production matters, not only for the raw materials, manufacture, licensing, and distribution of pharmaceuticals but also for the making of basic scientific knowledge. Consideration of this case exposes the limitations of global health frameworks that implicitly posit rich countries as the only sites of knowledge production. Analysis of iThemba identifies the problems inherent in global north/south divides at the same time as it highlights what is at stake in who makes knowledge and where. It also provides a concrete example for consideration of the contexts and practices of postcolonial science, its constraints, and its promise. Synthesizing Hope explores the many legacies that create conditions of possibility for South African drug discovery, especially the specific form of settler colonialism characterized by apartheid and resource extraction. Paying attention to the infrastructures and laboratory processes of drug discovery underscores the materiality of pharmaceuticals from the perspective of their makers, and tracing the intellectual and material infrastructures of South African drug discovery contributes new insights about larger social, political, and economic orders.

Drug Development and Conservation of Biodiversity in West and Central Africa: Performance of Neurochemical and Radio Receptor Assays of Plant Extracts Drug Discovery for the Central Nervous System


Book Description

The thrust of the CNS assay panel was to identify plant extracts that display moderate to high affinity for selected molecular targets. Target selection was based identifying active plant extracts that would be useful for one or more neuropsyschiatric disorders. We completed a screen for 102 samples belonging to 43 plants. 41 showed activity at one or more CNS targets. Phytochemical studies have been initiated on several active extracts. A total of 12 plants samples which have tested positive for antiplasmodial activity were collected in bulk quantities for detailed phytochemical investigations into antimalarial and trypanocidal activity.




Drugs in Africa


Book Description

This cutting-edge volume is the first to address the burgeoning interest in drugs and Africa among scholars, policymakers, and the general public. It brings together an interdisciplinary group of leading academics and practitioners to explore the use, trade, production, and control of mind-altering substances on the continent




Social and Technological Innovation in Africa


Book Description

This book examines the landscape of sustained investment in research and innovation in Africa, which are critical for development. This cutting-edge analysis is based on empirical evidence and the author’s experience in managing health and related innovations on the continent and globally. It concludes, for the first time, that African innovation is largely driven by the principles of Social, rather than Technological innovation. The significance of this finding and the need to optimize, scale and sustain this dominant innovation is addressed in various chapters that analyze the status, challenges and opportunities. Particularly, the financing, collaboration and coordination patterns for these activities on the continent show a fragmented ecosystem that is largely dependent on external donors and aid. The importance of supportive policies, leadership and venture mechanisms that incentivizes public and private entities to innovate is further exemplified by the lessons of the COVID-19 pandemic. The book proposes mechanism to address identified challenges.




Random and Rational Approaches to HIV Discovery in Africa


Book Description

The drug discovery and development process is an inherently lengthy endevour, with the devlopment of a compund from initial discovery to market approval averaging between 10 and >15 years. It is also widely acknowldeged as a costly endevour although the precise costs, and the methodology to calculate them, have been highly debated. [partial abstract].




Africa and the Sustainable Development Goals


Book Description

The book draws upon the expertise and international research collaborations forged by the Worldwide Universities Network Global Africa Group to critically engage with the intersection, in theory and practice, of the Sustainable Development Goals (SDGs) and Africa’s development agendas and needs. Further, it argues that – and demonstrates how – the SDGs should be understood as an aspirational blueprint for development with multiple meanings that are situated in dynamic and contested terrains. As the SDGs have substantial implications for development policy and resourcing at both the macro and micro levels, their relevance is not only context-specific but should also be assessed in terms of the aspirations and needs of ordinary citizens across the continent. Drawing on analyses and evidence from both the natural and social sciences, the book demonstrates that progress towards the SDGs must meet demands for improving human well-being under diverse and challenging socio-economic, political and environmental conditions. Examples include those from the mining industry, public health, employment and the media. In closing, it highlights how international collaboration in the form of research networks can enhance the production of critical knowledge on and engagement with the SDGs in Africa.

Bitter Roots


Book Description

For over a century, plant specialists worldwide have sought to transform healing plants in African countries into pharmaceuticals. And for equally as long, conflicts over these medicinal plants have endured, from stolen recipes and toxic tonics to unfulfilled promises of laboratory equipment and usurped personal patents. In Bitter Roots, Abena Dove Osseo-Asare draws on publicly available records and extensive interviews with scientists and healers in Ghana, Madagascar, and South Africa to interpret how African scientists and healers, rural communities, and drug companies—including Pfizer, Bristol-Myers Squibb, and Unilever—have sought since the 1880s to develop drugs from Africa’s medicinal plants. Osseo-Asare recalls the efforts to transform six plants into pharmaceuticals: rosy periwinkle, Asiatic pennywort, grains of paradise, Strophanthus, Cryptolepis, and Hoodia. Through the stories of each plant, she shows that herbal medicine and pharmaceutical chemistry have simultaneous and overlapping histories that cross geographic boundaries. At the same time, Osseo-Asare sheds new light on how various interests have tried to manage the rights to these healing plants and probes the challenges associated with assigning ownership to plants and their biochemical components. A fascinating examination of the history of medicine in colonial and postcolonial Africa, Bitter Roots will be indispensable for scholars of Africa; historians interested in medicine, biochemistry, and society; and policy makers concerned with drug access and patent rights.
