What Makes an Effective PROTAC? Unlocking Drug-Resistant Pathways Through Warhead, Linker, and Anchor Modifications
Description
Research Paper Description; This research investigates the structural design of PROTACs (Proteolysis-Targeting Chimeras), a novel class of therapeutic molecules that induce targeted protein degradation by recruiting specific E3 ubiquitin ligases to disease-related proteins. The study explores how variations in the three key components of PROTACs , the warhead (target-binding ligand), the linker (spacer), and the anchor (E3 ligase ligand) , influence their ability to reach and degrade proteins that are typically inaccessible to traditional small molecule drugs. By analyzing five theoretically designed PROTAC candidates targeting CDK9, a kinase implicated in cancer, this paper aims to highlight design strategies that optimize selectivity, binding cooperativity, and degradation efficiency. The work also emphasizes the potential of PROTACs to act as “smart drugs,” capable of bypassing limitations in conventional drug therapy by hijacking the cell’s own protein disposal system.
