Description

Danusertib, also known as PHA-739358, is a small-molecule 3-aminopyrazole derivative with potential antineoplastic activity. Aurora kinase inhibitor PHA-739358 binds to and inhibits the Aurora kinases, which may result in cell growth arrest and apoptosis in tumor cells in which Aurora kinases are overexpressed. This agent may preferentially bind to and inhibit Aurora B kinase. Aurora kinases, a family of serine-threonine kinases, are important regulators of cellular proliferation and division.

How to use

In Vitro:

Danusertib inhibits the activities of other kinases such as FGFR1, Abl, Ret and Trka, with IC50 of 47 nM, 25 nM, 31 nM and 31 nM, respectively. In a cell assay, after treatment of wild-type and p53-deficient MEFs with Danusertib, the wild-type cells undergo an arrest in mitosis (4N) that is maintained for up to 48 h. The p53-deficient cells on the other hand do not arrest at the 4N DNA stage, but continues with additional rounds of DNA synthesis to become >8N. Treatment with Danusertib results in an increase in p53 protein levels and an associated increase in p21 protein, which is known to be transcriptionally regulated by p53. Increasing concentrations of Danusertib produces a dose-dependent reduction of cell growth after 48 hours in BCR-ABL-positive (K562, BV173) and BCR-ABL-negative (HL60) cells.

In Vivo:

Administration of 25 mg/kg Danusertib (b.d. i.v.) to HL-60 xenograft rats results in 75% inhibition of tumor growth with complete regression in one animal. Danusertib results in biomarker modulation accompanied by inhibition of tumor growth. This is compatible with an expected mechanism of action of aurora kinase inhibition. Danusertib significantly inhibits proliferation of K562 cells and virtually suppressed tumor growth during the 10-day treatment period.
