Description: AZD-1152 HQPA, also known as AZD-2811, is a potent and selective Aurora B inhibitor (IC50 of 0.37 nM versus 1368 nM for Aurora B and A kinases, respectively), serine/ threonine kinase inhibitor, and an active metabolite of Barasertib ( AZD-1152). Barasertib is a prodrug and will be converted rapidly to the active drug AZD1152-HQPA in human plasma. Preliminary studies showed that AZD-1152 was active against a variety of solid tumors including colon, breast, and lung cancers. IMPORTANT NOTE: AZD-1152HQPA IS NOT AZD-1152 or Barasertib. Many vendors is selling Barasertib with wrong structure

Additional Information

722543-50-2 (Barasertib or AZD-1152 dihydrochloride salt)
722543-31-9 (Barasertib or AZD-1152 free form)
722544-51-6 (AZD-1152-HQPA)

AZD1152-HQPA is a highly potent and selective Aurora B inhibitor with a Ki of 0.36 nM. AZD1152-HQPA inhibits Aurora A with a Ki of 1.37 nM. AZD1152 is converted rapidly to the active AZD1152-HQPA (Barasertib) in plasma. AZD1152-HQPA has a high specificity versus a panel of 50 other kinases. Consistent with inhibition of Aurora B kinase, addition of AZD1152-HQPA to tumor cells in vitro induces chromosome misalignment, prevents cell division, and consequently reduces cell viability and induces apoptosis.
