AZD9272 (10 μM) does not diminish the response to 10 μM ATP in the background GHEK cells. Increasing concentrations of AZD9272 causes a decrease in the potency and the maximal response of DHPG.[1] AZD9272 completely reverses the glutamate-stimulated (EC80=80 μM) phosphatidyl inositol hydrolysis in human mGluR5-GHEK cells in a concentration-dependent manner, with IC50 of 26±3 nM (n=21).[1]
In vivo(体内研究)
AZD 9272 (3 μmol/kg; single intravenous) is eliminated from plasma with terminal half-lives between 2 and 6 h. The terminal half-lives following oral dosing are similar to the half-lives following intravenous dosing. The volume of distribution at steady state is intermediate for AZD9272.[1] AZD9272 (2.84 mg/kg) causes greater than 80% and typically more than 99% MTEP-appropriate responding up to 20 hours after dose, with a decline to approximately 20% at 24 hours after dose, yielding a t1/2 of 21.93 hours, and causes no systematic effects on response rates. The first-time point at which AZD9272 causes >90% MTEP-appropriate response is at 30 minutes after the dose.[2]

PARP
In vitro(体外研究)
AZD2461 has lower affinity for Pgp than does Olaparib.
In vivo(体内研究)
AZD2461 has an 80-fold increased Mdr1b expression on Olaparib-resistant KB1P tumor T6-28, without inhibition of Pgp. AZD2461 induces loss of 53BP1 expression in mice with KB1P tumors with short-term treatment. Long-term AZD2461 treatment is well tolerated and doubled the median relapse-free survival.
