Despite more than fifty years of intensive research on Alzheimer’s disease (AD) drug discovery, up till now only four medicines are approved by FDA for its treatment; among which three are acetylcholinesterase (AChE) inhibitors (donepezil, galantamine, and rivastigmine) and one is N-Methyl-D-aspartate (NMDA) antagonist memantine. These medications were launched during the initial research for AD but were not able to provide satisfactory results because of their limited efficacy and numerous side effects. The high-profile failure of late-stage clinical trials by prominent pharma firms for biomolecules that showed promising results in experimental models has added to the dissatisfaction of drug development research for AD in recent years. The global dementia patient population was expected to be 50 million in 2017, with projections of 82 million and 152 million in 2030 and 2045, respectively. There is a significant flaw in our understanding of AD pathology, as well as in the experimental models we use to depict human pathology and our therapeutic methods. In light of this, this Research Topic is created to highlight the critical significance of natural products in therapeutic development for human diseases. The therapeutic potential of several natural products, including crude extracts and purified compounds, has been demonstrated in numerous experimental models, with pharmacological efficacy comparable to that of known medicines. This includes effects via specific biological targets (enzymes, receptors, ion channels, and so on) or a variety of mechanisms extending from basic antioxidants and anti-inflammatory mechanisms to neuroprotection and neuroregeneration pathways. Insights into AD therapy using natural products in the form of original research articles or reviews in all areas of AD pathology, experimental designs, and therapeutic approaches are encouraged. The main goal of this collection is to put light on the current status of natural products in AD. As natural products including many polyphenols or other agents are given in combination with marketed available AD drugs to increase their efficacy. So, all those research areas that cover the current status of natural products in single or in combination with other agents to improve the efficacy of AD/dementia will be focused on. • Natural products targeting AD (In-vitro, in-vivo, and in-silico); • Drug discovery for AD by targeting pathways; • Combination therapy to improve the efficacy of Anti-AD agents; • Polytherapy vs single chemical entity; • Experimental models of dementia; • Novel bioassays for cognitive disorders.

Natural Products have been important sources of useful drugs from prehistoric times to the present. This book gives an overview about this field and provides important recent contributions to the discovery of new drugs generated by research on natural products. Total synthesis of natural products with interesting biological activities is paving the way for the preparation of new and improved analogs. The methods of combinatorial chemistry permit the selection of the best drug from a large number of candidates. Beyond synthesis and evaluation of organic molecules a number of new bioorganic methods are coming to the fore and will be discucced in this isue of the ERnst schering Research Foundation workshop proceedings.

Neuroscience Perspectives provides multidisciplinary reviews of topics in one of the most diverse and rapidly advancing fields in the life sciences.Whether you are a new recruit to neuroscience, or an established expert, look to this series for 'one-stop' sources of the historical, physiological, pharmacological, biochemical, molecular biological and therapeutic aspects of chosen research areas.The last decade has seen tremendous advances in our understanding of the pathobiology of Alzheimer's disease. These will lead to the first generation of drugs aimed at prevention rather than cure. This book covers some of the most important and exciting of these advances, with chapters written by many of the leading researchers in the field.With genetic studies as a backbone to this volume many chapters are devoted to the function and regulation of amyloid b-protein precursor (APP) and apolipoprotein E (ApoE). Other chapters describe cell biological approaches helping to piece together the link between the genetic alterations and the phenotype we call Alzheimer's disease.Although APP and its proteolytic cleavage product, amyloid b-protein, do not answer all the questions, detailed research into this system has undoubtedly increased our knowledge of the pathobiology of AD and has lead to the identification of other risk factors. Understanding the role of ApoE in the pathology of Alzheimer's disease promises to open a whole new field in AD research.* * Reviews the current knowledge of the pathogenesis of Alzheimer's Disease from a clinical perspective to a genetic and cell biological perspective* A comprehensive description of the role of amyloid B-protein precursor in Alzheimer's disease.* Up-to-date research data* Clear illustrations complement the text

Focuses on the effects of natural products and their active components on brain function and neurodegenerative disease prevention. Phytochemicals such as alkaloids, terpenes, flavanoids, isoflavones, saponins etc are known to possess protective activity against many neurological diseases. The molecular mechanisms behind the curative effects rely mainly on the action of phytonutrients on distinct signaling pathways associated with protein folding and neuro-inflammation. The diverse array of bioactive nutrients present in these natural products plays a pivotal role in prevention and cure of various neurodegenerative diseases, disorders, or insults, such as Alzheimer's Disease, Parkinson's Disease, Huntington's Disease, traumatic brain injury, and other neuronal dysfunctions. However, the use of these antioxidants in the management of neurodegenerative conditions has so far been not well understood. This is a comprehensive collection addressing the effects on the brain of natural products and edible items such as reservatrol, curcumin, gingerol, fruits, vegetables, nuts, and marine products.
