  • (c) Immunohistochemical images of intestinal sections from E-Rspo2 and R26-rtTA/P-Rspo3 mice treated with either DMSO or LGK974. BrdU was stained for proliferation. Scale bars, 100 μm.

    Nat Commun, 2017, 8:15945. LGK-974 purchased from Selleck.

    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.

Biological Activity

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.
Porcn [1]
(TM3 cells)
In vitro

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. [1] LGK974 specifically inhibits the growth of three RNF43-mutant cell lines, HPAF-II, PaTu 8988S, and Capan-2. [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. [1] LGK974 (5 mg/kg, p.o., BID) also inhibits tumor growth of RNF43-mutant pancreatic tumors (HPAF-II and Capan-2) in vivo. [2]


Cell Research:


+ Expand
  • Cell lines: HPAF-II, PaTu 8988S, and Capan-2 cells
  • Concentrations: ~1 μM
  • Incubation Time: 3 days
  • Method:

    Cells are plated in growth medium in a 96-well plate at a density of 6,000–12,000 cells per well and treated with DMSO or 1 μM LGK974. After 3 d, the cells are treated with fresh growth medium containing 20 μM EdU, which is included in the Click-iT EdU Alexa Fluor 488 HCS assay kit, and the plate was incubated for 2 h at 37 °C in a humidified atmosphere containing 5% CO2. Cells are fixed with final 4% (mass/vol) paraformaldehyde for 30 min, washed with PBS, permeabilized, and stained with 50 μg/mL Hoechst in PBS for 30 min. After wash, the cells are proceeded to EdU detection according to the instruction of Click-iT EdU assay kit. Triplet wells are performed for each condition.
