Template-assisted covalent modification underlies activity of covalent molecular glues.

ABSTRACT: Molecular glues are proximity-inducing small molecules that have emerged as an attractive therapeutic approach. However, developing molecular glues remains challenging, requiring innovative mechanistic strategies to stabilize neoprotein interfaces and expedite discovery. Here we unveil a trans-labeling covalent molecular glue mechanism, termed 'template-assisted covalent modification'. We identified a new series of BRD4 molecular glue degraders that recruit CUL4^DCAF16 ligase to the second bromodomain of BRD4 (BRD4_BD2). Through comprehensive biochemical, structural and mutagenesis analyses, we elucidated how pre-existing structural complementarity between DCAF16 and BRD4_BD2 serves as a template to optimally orient the degrader for covalent modification of DC
