Abstract
Alzheimer’s disease (AD) is an irreversible multifaceted neurodegenerative disorder that gradually degrades neuronal cells. Presently, it is the most common reason for the memory loss and dementia in older individuals. It is patho-physiologically described by extracellular amyloid beta (Aβ) deposition, intracellular neurofibrillary tangles (NFTs) retention, neuronal decline, and neurotransmitter system derangement. Various receptors such as nicotinic acetylcholine, N-methyl-D-aspartate, insulin, serotonin, adenosine, and histamine are actively involved in the physiological progression of AD. Till date memantine and only four other acetylcholinesterase inhibitors have been approved for the treatment of AD by US Food and Drug Administration (US-FDA). Hence, there is a critical need to explore and develop novel and helpful management systems which could specifically target different receptors involved in AD progression. We believe that these receptors targeting will either impede the disease onset or slow down its pathogenesis. In the present review, we tried to uncover some receptors that could be blocked by novel inhibitors and ultimately used for the therapeutic management of AD.
Keywords: Alzheimer's disease, Nicotinic acetylcholine receptors, N-methyl-D-aspartate receptor, Insulin receptor, Adenosine receptor.

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
