Introduction

The pursuit of new medicines is increasingly focused on complex biological targets that have traditionally been considered ‘undruggable.’ These include protein-protein interactions (PPIs), RNA, intrinsically disordered proteins (IDPs), and targets with shallow binding pockets. Overcoming the challenges associated with these targets requires innovative medicinal chemistry approaches, including fragment-based drug discovery (FBDD), PROTACs (proteolysis-targeting chimeras), molecular glues, and allosteric modulation. This course provides a comprehensive overview of these advanced strategies, equipping participants with the knowledge and practical skills to design and develop novel therapeutics against previously inaccessible targets. The course will blend theoretical concepts with real-world case studies, hands-on exercises, and interactive discussions. By the end of this program, participants will be well-equipped to contribute to groundbreaking drug discovery efforts focused on ‘undruggable’ targets, ultimately expanding the therapeutic landscape and improving patient outcomes.
