iMDK
Based on 7 publication(s) in Google Scholar
iMDK is a potent PI3K inhibitor and inhibits the growth factor MDK (also known as midkine or MK). iMDK suppresses non-small cell lung cancer (NSCLC) cooperatively with A MEK inhibitor without harming normal cells and mice.

Biological Activity
iMDK (50–500 nM) suppressed AKT phosphorylation in a dose-dependent manner in H441 lung adenocarcinoma cells after treatment for 72 h. In contrast, iMDK robustly increases p-ERK[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:H441 (lung adenocarcinoma; KRASG12V), H2009 (non-small cell carcinoma; KRASG12A), A549 (lung carcinoma; KRASG12S) and H520 (lung squamous cell carcinoma; KRASWT)
-
Concentration:iMDK (2.5 μM) and PD0325901 (0.5 μM) for H441 and H2009 cells
iMDK (0.125 μM) and PD0325901 (0.25 μM) for H520 cells
iMDK (0.25 μM) and PD0325901 (0.125 μM) for A549 cells -
Incubation Time:72 hours
-
Result:iMDK alone did not inhibit cell viability of A549 cells, the combinatorial treatment of iMDK with PD0325901 significantly inhibited that of A549 cells compared to the single treatment of PD0325901.
-
Cell Line:H441 lung adenocarcinoma cells
-
Concentration:0-500 nM
-
Incubation Time:72 hours
-
Result:Suppressed AKT phosphorylation in a dose-dependent manner.
ERK1/2 phosphorylation was increased.

-
Animal Model:female BALB/c nude mice (6 week old) bearing H441 human lung cancer xenografts[1]
-
Dosage:iMDK (9 mg/kg) and PD0325901 (5 mg/kg)
-
Administration:Intraperitoneally injected with 100 μL iMDK everyday and/or orally administered PD0325901 five times per week (on days 1, 2, 3, 4, 5, 7, 8, 9, 10, 11)
-
Result:Reduced significantly volume of the tumors derived from H441 lung adenocarcinoma cells after the combination treatment with iMDK and PD0325901 compared to that of single compound in a xenograft mouse model.
