Problems solved by technology

[0014] However, given the restricted cellular localization of transmembrane proteins and the uncertain accessibility of membrane-bound receptors for ubiquitination via cytosolic mechanisms, an outstanding question is whether the PROTAC approach can induce degradation of transmembrane proteins

Abstract

The present disclosure relates to bifunctional compounds, which find utility as modulators of receptor tyrosine kinase (RTK) proteins. In particular, the present disclosure is directed to bifunctionalcompounds, which contain on one end a ligand which binds to an E3 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 effectuate ubiquitination, and therefore, degradation (and inhibition) of the target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation / inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions ofthe present disclosure.
