Product Information

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.
