Gan & Lee Pharmaceuticals Co. Ltd. has prepared and tested proteolysis targeting chimera (PROTAC) compounds comprising an E3 ubiquitin ligase binding moiety covalently linked to an estrogen receptor α(ER-α; ESR1) targeting moiety via a linker reported to be useful for the treatment of cancer.

Work at Dark Blue Therapeutics Ltd. has led to the development of new proteolysis targeting chimera (PROTAC) compounds comprising a E3 ubiquitin ligase-binding moiety coupled to a protein ENL (MLLT1; YEATS1) and/or protein AF-9 (MLLT3; AF9)-targeting moiety through a linker. They are reported to be useful for the treatment of cancer.

Researchers from Stanford School of Medicine and Yonsei University College of Medicine reported the discovery and preclinical characterization of novel KLHDC2-mediated CDK6-selective degraders.
