Background

Danusertib (previously known as PHA-739358), a 3-aminopyrazole derivative identified during the development of the pyrrolopyrazole sub-series, is a potent small-molecule inhibitor of aurora kinases family members with a dominant inhibition for aurora B kinase (ABK). This pan-aurora kinases inhibitor is also able to inhibit several tyrosine kinases, including T315I mutant, Ret, Trk-A and fibroblast growth factor receptor-1 (FGFR-1), which are involved in multiple malignancies, such as chronic myelogenous leukemia (CML), acute lymphoblastic leukemia (ALL), thyroid prostate and breast carcinoma. Thus, in many previous studies, danusertib exhibits remarkable antitumor activity in a number of different xengorafts, spontaneous, and transgenic animal tumor models with a favorable pharmacokinetic and safety profile.

Protocol

Kinase experiment [1]:
Biochemical kinase assays	The Km values for ATP and the specific substrate were initially determined, and each assay was then run at optimized ATP (2Km) and substrate (5Km) concentrations. This setting enabled direct comparison of IC50 values of Danusertib across the applied kinase selectivity screening panel for the evaluation of the selectivity profile.
Cell experiment [2]:
Cell lines	CD34+ cells
Preparation method	The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20 °C for several months.
Reaction Conditions	5 μM; 5 days
Applications	In CD34+ cells from an IM-resistant CML patient, Danusertib induced apoptosis and reduced phosphorylation of P-CrkL.
Animal experiment [2]:
Animal models	Female SCID mice s.c. injected with K562 cells
Dosage form	15 mg/kg; i.p.; b.i.d., for 10 days
Applications	Danusertib significantly inhibited K562 cell proliferation and virtually suppressed tumor growth.
Other notes	Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
