AP1/Jun noncanonical Wnt activity measured in the presence of LGK974 (porcupine inhibitor) and JNK-IN-8 (JNK inhibitor) (both 1 μM). F: Aldosterone secretion during the same experiment (n=4). Results are expressed in mean SEM, and P values show significance between treatments and baseline control.

Nestin silencing inhibits the Wnt/β-catenin signaling in breast CSC. Nestin-si and Nestin-c breast CSC were cultured for 48 h, and the relative levels of target proteins and phosphorylation were determined by western blotting. Data are presented as the mean ± SD of the levels of target proteins vs. the β-actin control, or the phosphorylated vs. the total form, from six separate experiments. In addition, Nestinhigh in the presence or absence of LGK974 (1 nM), Nestinlow in the presence or absence of SB216763 (5 uM), and control CSC were tested for their proliferation via mammosphere formation assays. Quantitative analysis of the formed mammospheres. *P <0.05, vs. the Nestin-c or control, except for specifically indicated. CSC, cancer stem cell; SD, standard deviation.

|Description||LGK-974 is a potent and specific PORCN inhibitor, and inhibits Wnt signaling with IC50 of 0.4 nM in TM3 cells. Phase 1.|
|Features||Orally bioavailable Porcupine-specific inhibitor that has been tested in Phase I clinical trials for treatment of malignancies dependent on Wnt ligands.|
LGK974 effectively displaces [3H]-GNF-1331 with IC50 of 1 nM in the PORCN radioligand binding assay, and shows no major cytotoxicity in cells up to 20 µM. LGK974 shows comparable inhibitory activities against all tested Wnts with IC50 ranging from 0.05 to 2.4 nM, which is consistent with the genetic loss of PORCN phenotype.  LGK974 specifically inhibits the growth of three RNF43-mutant cell lines, HPAF-II, PaTu 8988S, and Capan-2. 
|In vivo||In a murine MMTV-Wnt1 tumor model and a human head and neck squamous cell carcinoma model (HN30), LGK974 (3 mg/kg) inhibits Wnt signaling in vivo and induces tumor regression without significant body weight loss in the mice.  LGK974 (5 mg/kg, p.o., BID) also inhibits tumor growth of RNF43-mutant pancreatic tumors (HPAF-II and Capan-2) in vivo. |

For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
