MedKoo Cat#: 205467 | Name: Ipatasertib (GDC-0068)
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Ipatasertib, also known as GDC-0068, is an orally bioavailable inhibitor of the serine/threonine protein kinase Akt (protein kinase B) with potential antineoplastic activity. Akt inhibitor GDC-0068 binds to and inhibits the activity of Akt in a non-ATP-competitive manner, which may result in the inhibition of the PI3K/Akt signaling pathway and tumor cell proliferation and the induction of tumor cell apoptosis.

More Info
Activation of the PI3K/Akt signaling pathway is frequently associated with tumorigenesis and dysregulated PI3K/Akt signaling may contribute to tumor resistance to a variety of antineoplastic agents.
Biological target:
Ipatasertib (GDC-0068) is an ATP-competitive pan-Akt inhibitor with IC50s of 5, 18 and 8 nM for Akt1, Akt2 and Akt3, respectively.
In vitro activity:
In contrast, LREX, which is poised to upregulate GR expression to achieve enzalutamide resistance (8), was confirmed to be completely resistant to enzalutamide but had a marked response to ipatasertib (Fig. 1A, third panel). Consistent with its mechanism of action, the effect of ipatasertib on cell viability correlated with inhibition of AKT signaling, which is manifest as an increase in AKT phosphorylation (due to its ability to protect against phosphatases) and decrease in phosphorylation of downstream targets (Fig. 1B). As expected, enzalutamide decreased AR activity, demonstrated by decreased expression of canonical AR targets PSA and NKX3 in C4-2 and LREX cells, though not in 22RV1 cells, which express the AR variant AR-V7. Interestingly, C4-2 and LREX had increased expression of these canonical AR targets in the presence of ipatasertib. To determine whether ipatasertib has an anticancer effect in hormone-sensitive prostate cancer (HSPC), this study tested its effect in the well-characterized HSPC cell lines LNCaP and LAPC4. Both models of HSPC were more sensitive to ipatasertib than to androgen withdrawal (Supplementary Fig. S1A).

In vivo activity:
In the PIK3CA-MT MDA-MB-361 BCBM tumor model, GDC-0068 resulted in a significant inhibition of tumor growth measured by BLI in treated mice, whereas in contrast, sham-treated tumors continued to grow more rapidly (Figure 4A–C). No differences in tumor growth and survival were detected in MDA-MB-231 BrM2 intracranial tumors over the course of treatment (Supplementary Figure 2). Treatment with GDC-0068 led to a significant inhibition in the MDA-MB-361 tumor bearing mice compared with sham (mixed effect model, effect of treatment at day 77: P < 0.0001) (Figure 4B). Furthermore, treatment with GDC-0068 resulted in a significant survival benefit (log-rank test, P = 0.0008), with a median survival of 109 days in treated mice versus 82.5 days in mice receiving sham treatment (Figure 4D). To evaluate GDC-0068–induced phosphorylation inhibition of PI3K/Akt/mTOR pathway downstream targets, expression of p-PRAS40 and p-S6 ribosomal protein was analyzed with immunohistochemistry. In accordance with the previous in vitro and in vivo results, GDC-0068 treated tumors in MDA-MB-361 tumor bearing mice revealed reduced immunostaining of p-S6 ribosomal protein compared with tumors of the sham cohort (Figure 4E), but no such effect was seen in the PIK3CA-mutant cell line MDA-MB-231 BrM2 (Supplementary Figure 2).
