In this episode, Jesse Gordon-Blake, PhD, delves into the intricacies of medicinal chemistry, particularly focusing on drug discovery for ALS (amyotrophic lateral sclerosis). Jesse explains the process of discovering molecules that modulate biological pathways, the difference between structure-based and phenotype-based drug design, and the role computational methods play in drug development. The conversation also explores the challenges of crossing the blood-brain barrier, the importance of validating target response, and the complexities of progressing from a theoretical compound to preclinical studies. Additionally, Jesse touches on the significance of target product profiles, CNS drug design characteristics, and the iterative nature of medicinal chemistry. He concludes by discussing his current projects at Cortex, including fundraising strategies and timelines for drug development.
