Rational Design of CDK12/13 and BRD4 Molecular Glue Degraders.
Targeted protein degradation (TPD) is an emerging therapeutic approach for the selective elimination of disease-related proteins. While molecular glue degraders exhibit drug-like properties, their discovery has traditionally been serendipitous and often requires post-hoc rationalization. In this study, we demonstrate the rational, mechanism-guided design of molecular glue degraders using gluing moieties. Building on established principles, by appending a chemical gluing moiety to several small molecule inhibitors, we successfully transformed them into degraders, obviating the need for a specific E3 ubiquitin ligase recruiter. Specifically, we found that incorporating a hydrophobic aromatic ring or a double bond into a cyclin-dependent kinase 12 and 13 (CDK12/13) dual inhibitor enabled the recruitment of DNA damage-binding protein 1 (DDB1), thereby transforming a high-molecular-weight bivalent CDK12 degrader into a potent monovalent CDK12/13 molecular glue degrader. We also showcase that attaching a cysteine-reactive warhead to a bromodomain-containing protein 4 (BRD4) inhibitor converts it into a degrader by recruiting the DDB1 and CUL4 associated factor 16 (DCAF16) E3 ligase.
