Abstract
Recent data from epidemiologic studies have shown that the majority of the public health costs are related to age-related disorders, and most of these diseases can lead to neuronal death. The specific signaling mechanisms underpinning neurodegeneration and aging are incompletely understood. Much work has been directed to the search for the etiology of neurodegeneration and aging and to new therapeutic strategies, including not only drugs but also non-pharmacological approaches, such as physical exercise and low-calorie dietary intake. The most important processes in aging-associated conditions, including neurodegeneration, include the mammalian (or mechanistic) target of rapamycin (mTOR), sirtuin (SIRT) and insulin/insulin growth factor 1 signaling (IIS) pathways. These longevity pathways are involved in an array of different processes, including metabolism, cognition, stress response and brain plasticity. In this review we focus on the current advances involving the mTOR, SIRT and IIS longevity pathways during the course of healthy aging processes and neurodegenerative diseases, bringing new insights in the form of a better understanding of the signaling mechanisms underpinning neurodegeneration and how these differ from physiological normal aging processes. This also provides new targets for the therapeutic management and/or prevention of these devastating age-related disorders.

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
Chemistry Based on Natural Products for Therapeutic Purposes
The development of new pharmaceuticals for a wide range of medical conditions has long relied on the identification of promising natural products (NPs). There are over sixty percent of cancer, infectious illness, and CNS disease medications that include an NP pharmacophore, according to the Food and Drug Administration. Since NP ...read more
Current Trends in Drug Discovery Based on Artificial Intelligence and Computer-Aided Drug Design
Drug development discovery has faced several challenges over the years. In fact, the evolution of classical approaches to modern methods using computational methods, or Computer-Aided Drug Design (CADD), has shown promising and essential results in any drug discovery campaign. Among these methods, molecular docking is one of the most notable ...read more
