Akt1 and Akt2-IN-1 is an allosteric inhibitor of Akt1 (IC50=3.5 nM) and Akt2 (IC50=42 nM). It has potent and balanced activity.

Akt1 and Akt2-IN-1 (Compound 17) has moderate activity in an hERG binding assay (IC50=5610 nM) and is a substrate for human P-glycoprotein[1]. Consistent with the allosteric mode of inhibition, Akt1 and Akt2-IN-1 (Compound 17) is dependent on the PH-domain for Akt inhibition. Akt1 and Akt2-IN-1 (Compound 17) is selective for Akt1/2 over Akt3 (IC50=1900 nM), and is highly selective over other members of the AGC family of kinases (>50 μM vs PKA, PKC, SGK).

Akt1 and Akt2-IN-1 (Compound 17) is well tolerated in at exposures that provide high levels of Akt1 and 2 inhibition in vivo. Akt1 and Akt2-IN-1 (Compound 17) shows good pharmacokinetics in rat with a low clearance of 4.6 mL/min/kg and a half-life of 3.8 h. Due to the improved cell potency, physical properties, and rodent pharmacokinetics of Akt1 and Akt2-IN-1 (Compound 17), tolerability and Akt inhibition are assessed in mice. Akt1 and Akt2-IN-1 (Compound 17) has also been shown to inhibit the growth of A2780 tumors in vivo when used as monotherapy and has potent inhibitory activity against Akt1 and 2 in vivo in a mouse lung and efficacy in a tumor xenograft model. Using an acute dosing schedule (IP dosing of 50 mg/kg at times 0, 3, and 8 h), administration of Akt1 and Akt2-IN-1 (Compound 17) is well tolerated in mice and shows high levels of Akt inhibition in mouse lung[1].
