Product Introduction
Bioactivity
Name
AT7867 dihydrochloride
Description
AT7867 dihydrochloride is a potent ATP-competitive inhibitor of Akt1 / Akt2 / Akt3 and p70S6K / PKA kinase with IC 50 s of 32 nM/17 nM/47 nM and 85 nM/20 nM, respectively. AT7867 dihydrochloride is able to induce pharmacodynamic changes and inhibit human tumor xenograft growth.
In vitro
AT7867 ATP-competitive inhibited AKT2 with the Ki of 18nM. AT7867 also shows potent activity against the structurally related AGC kinases p70S6K and PKA, but shows a clear window of selectivity against kinases from other kinase sub-families. In vitro growth inhibition studies show that AT7867 blocks proliferation in a number of human cancer cell lines. AT7867 appears to be most potent at inhibiting proliferation in MES-SA uterine, MDA-MB-468 and MCF-7 breast, and HCT116 and HT29 colon lines (IC 50 values range from 0.9-3 μM), and least effective in the two prostate lines tested (IC 50 values range from 10-12 μM) [1].
In vivo
Following oral administration at 20 mg/kg, the elimination of AT7867 from plasma seems to be similar to that observed after i.v. administration. Plasma levels of AT7867 remain above 0.5 μM for at least 6 hours following an oral dose of 20 mg/kg. Assuming linear pharmacokinetics following i.v. administration, the bioavailability by the oral route is calculated to be 44%. In vivo pharmacodynamic (PD) biomarker studies are therefore performed with this model. Following pharmacokinetic and tolerability studies, doses of AT7867 (90 mg/kg p.o. or 20 mg/kg i.p.) are administered to athymic mice bearing MES-SA tumors and the phosphorylation status of GSK3β and S6RP in tumors is monitored over time. Clear inhibition of phosphorylation of the two markers of pathway activity is seen at 2 and 6 hours following treatment with AT7867. By 24 hours, total levels of both GSK3β and S6RP are greatly reduced [1].
