Abstract
Despite extensive research, there is an unmet need for developing disease-modifying therapies for Parkinson’s disease (PD). Failure of certain landmark clinical trials has highlighted the need for a better understanding of the disease pathogenesis as well as identifying the hurdles in developing drug candidates and designing clinical trials. While adhering to these needs, several promising trials are currently underway with the hope of developing reliable targets. There is also a need to conduct research on plant-based natural products and use them as therapeutic candidates for PD. In this context, many studies have demonstrated the efficacy of medicinal plants and their principal phytochemicals. This review provides an update on the presently underway clinical trials with a small emphasis on the disease modifying therapies that target small molecules, mitochondria, and oligodendrocytes. The role of ethnopharmacology-based approaches for treatment of PD has also been discussed. The third aspect of the article considers the importance of nanomedicine in this area, including the use of liposomes and nanoparticles to provide a novel approach for the treatment of PD.

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
