PF-AKT400 is a broadly selective, potent, ATP-competitive Akt inhibitor, displays 900-fold greater selectivity for PKBα ( IC 50 =0.5 nM) than PKA ( IC 50 =450 nM). In Vitro PF-AKT400 (Compound 42) provides significantly enhanced selectivity for Akt relative to earlier leads such as spiroindoline 2. Free IC 50 and EC 50 values are estimated for phospho-S6 reduction (110 nM) and Akt hyperphosphorylation (216 nM), respectively. These values corresponded well to the cellular IC 50 for PF-AKT400 in U87 cells measuring p-GSK-3α (310 nM). MCE has not independently confirmed the accuracy of these methods. They are for reference only. In Vivo PF-AKT400 is subsequently evaluated for modulation of Akt in tumors and in multiple in vivo mouse models of antitumor efficacy. It is active in a PC3 prostate carcinoma xenograft experiment, with 75% TGI observed at 100 mg/kg b.i.d. dosing for 10 days. In a colorectal carcinoma (Colo205) xenograft study, PF-AKT400 produces 60% TGI at 150 mg/kg b.i.d. after 10 days. Most intriguingly, in combination with Rapamycin (10 mg/kg, ip), 75 mg/kg b.i.d. (10 days) of PF-AKT400 results in 98% TGI in an additional PC3 prostate carcinoma xenograft study compared to 56% TGI and 66% TGI with PF-AKT400 and Rapamycin as single agents. To define the in vivo potency of PF-AKT400 (Compound 42) in the PC3 xenograft model, oral administration of 25, 75, and 100 mg/kg PF-AKT400 is performed with blood and tumor sampling over time. Immunoblot analysis of detergent-soluble extracts derived from PC3 tumors shows a significant reduction of S6 phosphorylation, and hyperphosphorylation of Akt upon treatment at doses that produced significant tumor growth inhibition. Plasma drug concentrations peak rapidly after oral administration of doses between 25-100 mg/kg (T max =0.5 h). Peak PD responses of phospho-S6 and phospho-Akt are observed at approximately 2-4h and 1h post-administration of PF-AKT400, respectively. The time-course of PD marker response is well described by a PK/PD model at doses that ranged from no efficacy (25 mg/kg) to maximal efficacy (100 mg/kg). MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal administration Mice Studies to describe the PK/PD relationship for PF-AKT400 are performed in male SCID/Beige mice bearing subcutaneous PC3 prostate carcinoma xenografts. Once tumors reach about ~300mm 3 in size, PF-AKT400 is formulated in 0.5% methylcellulose vehicle and administered orally to 3 mice per dose group. Plasma and tumors are harvested over time, tumor lysates prepared, and the levels of phospho S6 reduction and phospho Akt induction are evaluated by immunoblot. aladdin has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:PKBα 0.5 nM (IC 50 ) PKA 450 nM (IC 50 )
