Notes: Pyrvinium is an anthelmintic and anticancer agent.{61022,61023} Dietary administration of pyrvinium reduces worm burden in mouse models of N. dubius, S. obvelata, or A. tetraptera infection (EC50s = 292, 4, and 17 ppm, respectively) but is lethal to mice at higher concentrations (LC50 = 600 ppm).{61022} Pyrvinium (1 μg/ml) induces cytotoxicity in PANC-1 cells cultured in glucose-deficient medium but not serum- or amino acid-deficient medium or complete medium.{61023} It reduces tumor growth in a PANC-1 mouse xenograft model when administered at a dose of 100 μg/mouse per day. Pyrvinium (10 nM) also binds to and activates casein kinase 1α (CK1α).{60124} It inhibits Wnt signaling (EC50 = ~10 nM in a reporter assay) in a CK1α-dependent manner. Formulations containing pyrvinium were previously used in the treatment of pinworm infections.
