LY3200882 is an orally active TGFbeta inhibitor. LY3200882 targets transforming growth factor-beta (TGFb), with potential antineoplastic activity. Upon administration, LY3200882 specifically targets and binds to TGFb, which prevents both the binding of TGFb to its receptor TGFbR and TGFb-mediated signal transduction. This may lead to a reduction in TGFb-dependent proliferation of cancer cells.

How to use
LY3200882 potently inhibits TGFβ mediated SMAD phosphorylation in vitro in tumor and immune cells in a dose dependent fashion. LY3200882 shows potent anti-tumor activity in the orthotopic 4T1-LP model of triple negative breast cancer and this activity correlated with enhanced tumor infiltrating lymphocytes in the tumor microenvironment. In in vitro immune suppression assays, LY3200882 has shown the ability to rescue TGFβ1 suppressed or T regulatory cell suppressed naive T cell activity and restore proliferation. LY3200882 inhibits NIH3T3 cell viability with an IC50 of 82.9 nM.
LY3200882 (60 mg/kg; oral gavage; twice a day; for 21 days; BALB/C female mice) treatment significantly delays tumor growth in CT26 model. LY3200882 potently inhibits TGFβ mediated SMAD phosphorylation in vivo in subcutaneous tumors in a dose dependent fashion. LY3200882 has shown anti-metastatic activity in vivo in an experimental metastasis tumor model (intravenous EMT6-LM2 model of triple negative breast cancer).
