Abstract: The present invention provides bifunctional compounds which act as protein degradation inducing moieties for a HER family protein, such as Her3. The present invention also provides methods for the targeted degradation of a HER family protein through the use of the bifunctional compounds that link a ubiquitin ligase-binding moiety to a ligand that is capable of binding to the HER family protein which can be utilized in the treatment of disorders modulated by a HER family protein.

Abstract: The present invention relates to bifunctional compounds, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present invention. In particular, the present invention is directed to compounds, which contain on one end a VHL ligand which binds to the ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. The present invention exhibits a broad range of pharmacological activities associated with compounds according to the present invention, consistent with the degradation/inhibition of targeted polypeptides.
