How to use

In Vitro:

PKI-179 inhibits the cell proliferation, with IC50s of 22 nM and 29 nM for MDA361 and PC3 cells, respectively. PKI-179 shows inhibitory activity against a panel of 361 other kinases, hERG and cytochrome P450 (CYP) isoforms at concentrations up to >30 μM, but does have activity for CYP2C8 (IC50=3 μM).

In Vivo:

PKI-179 (5-50 mg/kg; p.o. once daily for 40 days) inhibits the tumor growth and is well tolerated in nude mice bearing MDA-361 human breast cancer tumors. PKI-179 (50 mg/kg; p.o.) results in good inhibition of PI3K signaling in nude mice bearing MDA361 tumor xenografts. PKI-179 exhibits good oral bioavailability (98% in nude mouse, 46% in rat, 38% in monkey, and 61% in dog) and a high half-life (>60 min) .
