Biological Activity for LY 2109761

LY 2109761 is a selective dual TGF-β receptor type I and II (TβRI/II) inhibitor (Ki values are 38 and 300 nM in a cell-free assay, respectively); it inhibits the kinase activity of both TGF-βRI and TGF-βRII. In vitro, it significantly inhibits the growth, motility, and invasiveness of L3.6pl/GLT pancreatic cancer cells and completely suppresses TGF-β-induced Smad2 phosphorylation. In vivo, LY 2109761, in combination with Gemcitabine, significantly reduces tumor volume and spontaneous abdominal metastases in a murine model of metastatic pancreatic cancer. LY 2109761 is orally bioavailable.
