Small molecules that can be used for targeted protein degradation of CK1alpha, IKZF1 and IKZF3 (SJ-21-0048)

St. Jude Reference #SJ-21-0048

Description

Researchers at St. Jude created small molecules that target protein degradation of CK1alpha, IKZF1 and IKZF3 that can be used for the treatment of blood and solid tumor cancers. These compounds indicate greater potency over existing small molecules (lenalidomide).                                                                                     

Pictured below is the leading compound in this series SJ7095 with proteomics data to point to its selectivity in degradation of CK1a and IKZF1/3. The structure of this compound was disclosed at the ACS meeting in Chicago on Aug. 22, 2022.
