Abstract
Phosphodiesterases (PDEs) have gained attention as potential pharmacological targets for neuropsychiatric diseases due to their ability to hydrolyze the second messengers, cGMP and/or cAMP. It is well-known the relationship between cAMP signaling and inflammation. Since neuroinflammation is considered to play an important role in the pathology of brain disorders, inhibition of PDEs highly expressed in brain has emerged as an innovative strategy for the treatment of these pathologies. PDE4, 7, 8 and 10 inhibitors are presented here as promising drug candidates to overcome the partial efficacy and adverse effects of the current therapy for neuropsychiatric illness such as depression, cognitive impairments or schizophrenia. Enhancing the intracellular concentration of cAMP underlies the effects of PDE inhibitors in the above mentioned disorders.
Keywords: cAMP, Cognitive Impairment, Depression, Phosphodiesterase, inhibitors, Schizophrenia.

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
