Vismodegib (formerly known as GDC-0449; RG-3616; GDC0449; RG3616; trade name: Erivedge) is a potent, orally bioavailable, first-in-class and specific hedgehog pathway inhibitor with potential anticancer activity. It was given FDA approval in 2012 to treat basal-cell carcinoma as an anticancer medication. In a test conducted without cell culture, vismodegib inhibits hedgehog at an IC50 of 3 nM and P-gp at an IC50 of 3.0 μM. Vismodegib inhibits Hedgehog signaling by blocking the actions of the cell surface receptors PTCH and/or SMO, which are targets of the Hedgehog ligand. In January of 2012, Vismodegib received approval. This novel oral small molecule selectively inhibits the Hedgehog signaling pathway by targeting the Smoothened protein. Genetic mutations causing uncontrolled activation of Hedgehog signaling are present in medulloblastomas and basal cell carcinomas (BCC). More than 90% of BCC cases involve aberrant signaling in the Hedgehog pathway.

Enzyme Assay |
Vismodegib (GDC-0449) is an oral active inhibitor of the hedgehog pathway with an IC50 of 3 nM. Additionally, it has IC50 values of 3.0 μM and 1.4 μM for P-gp and ABCG2 inhibition, respectively.

Cell Assay |
MDCKII cells are allowed to adhere after being seeded at a density of 3 × 105 cells per well into 24-well plates. After that, the medium is switched to one that contains different medications (50 μM VP, 50 μM indomethacin, or 20 μM GDC-0449 in DMSO or DMSO alone as control). Nonfluorescent calcein-AM is then added to the mixture at a final concentration of 1.0 μM and the mixture is incubated for two hours at 37 °C. Following two washes with Hank's balanced salt solution buffer containing Ca2+ and Mg2+, cells are lysed by shaking in 0.01% Triton X-100 in PBS buffer for either an hour at room temperature or an overnight at 4 °C. Using a SpectraMax M5 Multi-Detection Reader and an excitation wavelength of 495 nm and an emission wavelength of 515 nm, the lysate is then transferred into 96-well plates, and the fluorescence signal resulting from the cell-derived calcein is quantify using spectrophotometry. There is complete darkness during all manipulations. Standardized to the control, all readings are reported as mean SEM.

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.93 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 2.5 mg/mL (5.93 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with heating and sonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
