Heterocyclic compounds for medical treatment

Abstract

The present invention provides heterocyclic compounds that bind to the ubiquitously expressed E3 ligase protein cereblon (CRBN) and their use for the treatment of abnormal cellular proliferation in a human or other host. The present invention also provides compounds that can be used as synthetic intermediates in the synthesis of bifunctional compounds used for targeted protein degradation.
