GDC-0449 (Vismodegib) is a potent and specific hedgehog (Hh) pathway, also inhibits ABCG2, Pgp and MRP1-important ABC transporters associated with MDR. The IC50 values of GDC-0449 for inhibition of ABCG2 and Pgp were 1.4 and 3.0μM, respectively. GDC-0449 (Vismodegib) has been used to treat medulloblastoma in animal models and has recently entered clinical trials for a variety of solid tumors.

| Cell lines | OM9;22 cell line |
| Preparation method | Cell proliferation assay The cells were seeded in 24- or 96-well plates at a density of 2 *105 mL -1 in the presence or absence of S9 feeder cells. The cells were treated with the inhibitor drugs at the indicated concentrations: dasatinib, 1–100nM; and GDC-0449, 100nM to 10 mM. Viable cells were counted by trypan blue exclusion or fluorescence-activated cell sorting. |
