Abstract
Advances in the understanding of the neurobiology of the nicotinic receptor have started to be matched by an appreciation of the potential role of these receptors in a variety of neuropsychiatric disorders. While alterations in nicotinic receptor number and / or function have been associated with such conditions as Alzheimers disease for several years, there is increasing evidence that nicotinic receptor function may play a significant role in other disorders as well including schizophrenia, Parkinsons disease, anxiety disorders, and attention deficit-hyperactivity disorder (ADHD). Research in our laboratory and those of other investigators have utilized sophisticated psychopharmacological, cognitive, electrophysiological, neuroimaging and other techniques to assess the impact of nicotinic receptor modulation on the clinical expression of these disorders. This manuscript reviews data, both experimental and clinical, relating to the role of nicotine and / or nicotinic receptor function in a variety of neuropsychiatric disorders with the perspective of developing appropriate targets for therapeutic drug development.
Keywords: Nicotine, Neuropsychiatric Disorders, Alzheimers disease, Parkinsons disease, schizophrenia

Adaptogens—History and Future Perspectives
Adaptogens are pharmacologically active compounds or plant extracts that are associated with the ability to enhance the body’s stability against stress. The intake of adaptogens is associated not only with a better ability to adapt to stress and maintain or normalise metabolic functions but also with better mental and physical ...read more
AlphaFold in Medicinal Chemistry: Opportunities and Challenges
AlphaFold, a groundbreaking AI tool for protein structure prediction, is revolutionizing drug discovery. Its near-atomic accuracy unlocks new avenues for designing targeted drugs and performing efficient virtual screening. However, AlphaFold's static predictions lack the dynamic nature of proteins, crucial for understanding drug action. This is especially true for multi-domain proteins, ...read more
Artificial intelligence for Natural Products Discovery and Development
Our approach involves using computational methods to predict the potential therapeutic benefits of natural products by considering factors such as drug structure, targets, and interactions. We also employ multitarget analysis to understand the role of drug targets in disease pathways. We advocate for the use of artificial intelligence in predicting ...read more
Challenges, Consequences and Possible Treatments of Anticancer Drug Discovery ll
The use of several compounds has been the subject of increasing interest in phytochemistry, biochemistry, and other fields of research at the chemistry-biology-ecosystems interface. In spite of the continued search for new anticancer drugs, cancer remains a leading cause of death. Cancer mortalities are expected to increase to 12.9 million, ...read more
