-
Animal Model:Sprague Dawley rats (male)[1]
-
Dosage:1 mg/kg (IV), 3 mg/kg (PO)
-
Administration:IV or PO, once (Pharmacokinetic Analysis)
-
Result:Showed high level of oral exposure and bioavailability.
-
Animal Model:Female OF1 mice, male beagle dogs[1]
-
Dosage:3 mg/kg (IV) and 10 mg/kg (PO) for mice, 0.1 mg/kg (IV), 0.3 mg/kg (PO) for dogs
-
Administration:IV or PO, once (Pharmacokinetic Analysis)
-
Result:Showed low clearance, moderate volume of distribution, and rapid absorption leading to moderate to long half-lives and high oral bioavailability.
-
Animal Model:Male Sprague Dawley rats, male beagle dogs[1]
-
Dosage:0.3, 3, 30, 100 mg/kg
-
Administration:PO, once (Pharmacokinetic Analysis)
-
Result:Led to under-proportional increases in exposure (both AUC and Cmax) and much longer Tmax values when it formulated as a suspension of the crystalline material.
-
Animal Model:Female athymic nude mice (bearing xenotransplanted Rat1-myr-p110α tumors)[1]
-
Dosage:3, 10, and 20 mg/kg
-
Administration:PO, daily for 8 days
-
Result:Observed dose-dependent exposure and PD responses, and showed a dose-dependent inhibition of tumor growth. The 3 mg/kg dose achieved 80% S473P-Akt inhibition only at the 1 h time point; the 10 mg/kg dose at the 1 and 4 h time points; and the 20 mg/kg at the 1, 4, and 10 h time points, with a high level of inhibition remaining at the 14 h time point (76%).

Animal Model:Mice bearing xenograft HBRX2524 human primary breast tumor[1] Dosage: 40 mg/kg
-
Dosage:40 mg/kg
-
Administration:PO, daily for 15 days
-
Result:Inhibited the tumor growth throughout the study, and showed a significant level of regression the end of the 15 day treatment period.
