The Benefits of Natural Products for Neurodegenerative Diseases


Book Description

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.

Neuroprotective Effects of Phytochemicals in Neurological Disorders


Book Description

Phytochemicals are naturally occurring bioactive compounds found in edible fruits, plants, vegetables, and herbs.

Neuroprotective Effects of Phytochemicals in Neurological Disorders explores the advances in our understanding of the potential neuroprotective benefits that these naturally occurring chemicals contain. Neuroprotective Effects of Phytochemicals in Neurological Disorders explores the role that a number of plant-based chemical compounds play in a wide variety of neurological disorders. Chapters explore the impact of phytochemicals on neurotraumatic disorders, such as stroke and spinal cord injury, alongside neurodegenerative diseases such as Alzheimer's and Parkinson's Disease, as well as neuropsychiatric disorders such as depression and schizophrenia. The chapters and sections of this book provide the reader with a big picture view of this field of research. Neuroprotective Effects of Phytochemicals in Neurological Disorders aims to present readers with a comprehensive and cutting edge look at the effects of phytochemicals on the brain and neurological disorders in a manner useful to researchers, neuroscientists, clinical nutritionists, and physicians.

Natural Products and Neuroprotection


Book Description

Neurodegenerative diseases, including Alzheimer’s, Parkinson’s, Huntington’s, and amyotrophic lateral sclerosis, are the most common pathologies of the central nervous system currently without a cure. They share common molecular and cellular characteristics, including protein misfolding, mitochondrial dysfunction, glutamate toxicity, dysregulation of calcium homeostasis, oxidative stress, inflammation, and ageing, which contribute to neuronal death. Efforts to treat these diseases are often limited by their multifactorial etiology. Natural products, thanks to their multitarget activities, are considered promising alternatives for the treatment of neurodegeneration. This book deals with two different forms of natural products: extracts and isolated compounds. The study of the bioactivity of the extracts is extremely important as many studies have demonstrated the synergistic effect of the combination of different natural products. On the other hand, the investigation of the activity of specifically isolated natural products can be also important to understand their cellular and molecular mechanisms and to define the specific bioactive components in extracts or foods. This book can be considered an important contribution to knowledge of the neuroprotective effect of natural products and presents a great deal of information, related to both the benefits but also the limitations of their use in counteracting neurodegeneration.




Current Status of Natural Products Targeting Alzheimer’s Disease


Book Description

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.
