GtoPdb Ligand ID: 12409

Synonyms: AK2292
Compound class: Synthetic organic
Comment: AK-2292 is a PROTAC that mediates degradation of the STAT5A/B transcription factors [1]. It contains a STAT5-binding ligand (AK-305; PubChem CID 166594169) linked to lenalidomide moeity that mediates cereblon binding, and directs the STAT5 proteins for ubiquitination and proteosomal degradation. AK-2292 was designed to evaluate STAT5 degradation as a therapeutic strategy for haematologic malignancies such as acute myeloid leukemia (AML). The PROTAC selectively inhibits phosphorylation and transcriptional activity of STAT5 in vitro and in vivo.
