Abstract
Although tremendous effort has been made over the past century to treat cancer effectively, the pace of drug development is far behind the increasing rate of cancer incidence and mortality. There are two major hurdles in anticancer drug development: dose-limiting toxic side effects that reduce either drug effectiveness or the quality of life of patients and complicated drug development processes that are costly and time consuming. Drug repositioning has recently gained increasing attention among cancer researchers as this approach utilizes existing drugs and is significantly cost- and time-effective. Existing drugs, particularly non-cancer drugs, have favorable safety profiles in humans and serve as an ever-increasing source for new anticancer drug discovery. Here we review the recent examples of drug repositioning of existing non-cancer drugs for preclinical and clinical introductions of cancer therapy.
Keywords: Cancer, Disulfiram, Doxycycline, Drug repositioning, Existing drugs, Mebendazole, Pyrvinium pamoate, Triclosan.

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
