Description: Barasertib is an orally bioavailable, small-molecule, dihydrogen phosphate prodrug of the pyrazoloquinazoline Aurora kinase inhibitor AZD1152–hydroxyquinazoline pyrazol anilide (AZD1152-HQPA) with potential antineoplastic activity. Upon administration and rapid conversion from the prodrug form in plasma, barasertib specifically binds to and inhibits Aurora kinase B, which results in the disruption of spindle checkpoint functions and chromosome alignment and, so, the disruption of chromosome segregation and cytokinesis. Consequently, cell division and cell proliferation are inhibited and apoptosis is induced in Aurora kinase B-overexpressing tumor cells. IMPORTANT NOTE: AZD-1152HQPA IS NOT AZD-1152 or Barasertib. Many vendors are selling Barasertib with the wrong structure.

Product Data:

Biological target: Barasertib (AZD1152) is an Aurora B inhibitor with an IC50 of 0.37 nM.
In vitro activity: Barasertib effectively reduced glucose uptake and lactate production in gastric cancer (GC) cells in a dose-dependent and time-dependent manner. The expression levels of GLUT1, LDHA and HK2 were decreased by barasertib treatment of GC cells. Furthermore, barasertib induced the expression of ribosomal protein S7 (RPS7), as a tumor suppressor, to regulate glucose metabolism. Reference: Anticancer Drugs. 2019 Jan;30(1):19-26.
In vivo activity: To test whether treatment with barasertib prevents the development of lung fibrosis, TGFα mice were concomitantly treated with Dox to induce TGFα expression and either barasertib (40 mg/kg body weight) or vehicle twice per day for 4 weeks (Fig 5A). Induction of TGFα caused extensive subpleural, perivascular, and peribronchial fibrosis (Fig 5B). TGFα‐activated mice that were concomitantly given barasertib showed reduced collagen staining with infrequent scattered small fibrotic areas. Further, there was a significant decrease in the lung weights and hydroxyproline levels in TGFα mice treated with barasertib compared to vehicle‐treated mice (Fig 5C and D). Together, these findings suggest that inhibition of AURKB activity by barasertib attenuates progressive fibrotic changes in TGFα mice. Reference: EMBO Mol Med. 2020 Sep 7;12(9):e12131.

Phase I study of  barasertib (AZD1152) .  barasertib (AZD1152) is a highly potent and selective Aurora B kinase inhibitor. The safety, efficacy and pharmacokinetic (PK) profile of barasertib were investigated in Japanese patients with advanced acute myeloid leukemia. Barasertib (50-1200mg) was administered as a continuous 7-day intravenous infusion every 21 days. No dose-limiting toxicities were reported and barasertib 1200mg was chosen for further evaluation in Japanese patients. Neutropenia and febrile neutropenia were the most commonly reported adverse events. The PK profile was similar to Western patients. A promising overall hematologic response rate of 19% was achieved, which warrants further investigation in these patients. (source: Leuk Res. 2011 Oct;35(10):1384-9. ).
