生物活性

製品説明 LGK-974 (NVP-LGK974, WNT974) is a potent and specific PORCN inhibitor, and inhibits Wnt signaling with IC50 of 0.4 nM in TM3 cells. Phase 1.
in vitro In the PORCN radioligand binding assay, LGK974 (WNT974) effectively displaces [3H]-GNF-1331 with an IC50 of 1 nM and shows no major cytotoxicity in cells up to 20 µM. It 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] This compound 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 (WNT974) (3 mg/kg) inhibits Wnt signaling in vivo and induces tumor regression without significant body weight loss in the mice. [1] This compound (5 mg/kg, p.o., BID) also inhibits tumor growth of RNF43-mutant pancreatic tumors (HPAF-II and Capan-2) in vivo. [2]
特徴 Orally bioavailable Porcupine-specific inhibitor that has been tested in Phase I clinical trials for treatment of malignancies dependent on Wnt ligands.

実験の流れ

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 (WNT974). 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.
