In vitro

Ipatasertib (GDC-0068) was tested against a broad panel of 230 kinases, and it only inhibits 3 kinases by >70% at 1 μM concentration (PRKG1α, PRKG1β, and p70S6K, with IC50 of 98 nM, 69 nM, and 860 nM, respectively). This compound displays >100-fold selectivity for Akt over PKA with IC50 of 3.1 μM. In LNCaP, PC3 and BT474M1 cells, it inhibits the phosphorylation of the Akt substrate, PRAS40 with IC50 of 157 nM, 197 nM, and 208 nM, respectively. Furthermore, it selectively inhibits cell cycle progression and viability of cancer cell lines driven by Akt signaling, including those with defects in the tumor suppressor PTEN, oncogenic mutations in PIK3CA, and amplification of HER2, with strongest effects in HER2+ and Luminal subtypes.

In vivo

Oral administration of Ipatasertib (GDC-0068) in PC3 prostate tumor xenografts model induces down-regulation of p-PRAS40. In BT474-Tr xenografts, this compound reduces pS6 and peIF4G levels, re-localizes FOXO3a to nucleus, and induces feedback upregulation of HER3 and pERK. It exhibits potent antitumor efficacy in multiple xenograft tumor models, including the PTEN-deficient prostate cancer models LNCaP and PC3, the PIK3CA H1047R mutant breast cancer model KPL-4, and MCF7-neo/HER2 tumor model.
