Echoes from the Past, Visions from the Future: A Journey into Medicinal Chemistry and Computational Drug Discovery

Drug discovery has evolved significantly since the early days of isolating natural compounds such as morphine from opium poppies in the early nineteenth century. Medicinal chemistry drastically changed with the development of aspirin, derived from willow tree extracts, marking the beginning of the synthetic chemistry era. As scientific knowledge expanded, so did the methodologies, transitioning from serendipitous findings to targeted chemical synthesis and high-throughput screening. In recent decades, the advent of computational techniques has revolutionized drug design, enabling researchers to model molecular interactions (mainly comparing structure-based drug design strategies) and predict biological activity (in special considering ligand-based drug design strategies) with unprecedented precision. This shift towards computational drug design has accelerated the discovery process, making it more efficient and allowing for the development of novel therapies with greater specificity and reduced side effects.
