Abstract
Many neurodegenerative diseases are late onset diseases, associated with aggregation of proteins, implying that aged cells are more susceptible to proteotoxic stress. It is known that with aging, there is a decline in the functionality of chaperone networks and on the other hand, accumulation of damaged proteins occurs. Together, this has a cumulative effects on cellular protein homeostasis. Several studies have revealed that availability of DNAJ proteins, the cochaperones to the Hsp70 machine, could be a rate-limiting factor in handling diseased proteins within the cell. In this review, we highlight how DNAJ proteins can affect aggregation of disease-causing proteins, if and how this depends on their function as Hsp70 co-chaperones, and how much this depends on the type of protein causing the disease. Finally, we will discuss the five known degenerative diseases that are linked to mutations in individual DNAJ members and what mechanism may underlie these DNAJ chaperonopathies.

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
