Abstract

Aberrant activation of the JAK-STAT signaling pathway has been implicated in the pathogenesis of a range of hematological malignancies and autoimmune disorders. Here we describe the design, synthesis, and characterization of JAK2/3 PROTACs utilizing a phenyl glutarimide (PG) ligand as the Cereblon (CRBN) recruiter. SJ10542 displayed high selectivity over GSPT1 and Other members of the JAK family and potency in patient-derived ALL cells containing both JAK2 fusions and CRLF2 rearrangements.
