Cat. No.: HY-10681 Purity: 99.68%
Handling Instructions

Gedatolisib (PKI-587) is a highly potent dual inhibitor of PI3Kα, PI3Kγ, and mTOR with IC50s of 0.4 nM, 5.4 nM and 1.6 nM, respectively. PKI-587 is equally effective in both complexes of mTOR, mTORC1 and mTORC2.

In Vitro

Gedatolisib (PKI-587) shows good potency in cell growth inhibition assays using MDA-361 and PC3-MM2 cell lines with IC50s of 4.0 and 13.1 nM, respectively[1].
Gedatolisib shows potent suppression of phosphorylation of PI3K/mTOR signaling pathway proteins in MDA-361 tumor cells. Gedatolisib (0.03-3 μM; 4 hours) prevents the phosphorylation of Akt at Thr 308 and induces cleaved PARP at 30 nM[1].

Western Blot Analysis[1]

Cell Line: MDA-361 tumor cells
Concentration: 0.03, 0.1, 0.3, 1, and 3 μM
Incubation Time: 4 hours
Result: Prevented the phosphorylation of Akt (pAkt) at threonine 308 (T308; IC50=8 nM).
In Vivo

Gedatolisib (PKI-587; administered i.v. at 20 mg/kg on days 1, 5, 9) exhibits potent antitumor efficacy against MDA-361 tumors in mice[1].
Gedatolisib exhibits terminal elimination half-life (T1/2 14.4 h) due to high plasma clearance (7 mL/min/kg) combined with large volumes of distribution (7.2 L/kg respectively) following i.v. administration (25 mg/kg) female nude mice[1].

Animal Model: Female nude mice bearing MDA-361 xenograft model[1].
Dosage: 20 mg/kg
Administration: Administered i.v. at 20 mg/kg on an intermittent regimen (days 1, 5, 9).
Result: Caused regression of large staged (~900 mm3) tumors.
The minimum efficacious dose (MED) was determined to be 3 mg/kg against MDA-361 tumors and maximum tolerated single dose (MTD) was determined to be 30 mg/kg.
