Protein tyrosine kinase (PTK) inhibitors are potential antiproliferative agents for diseases caused by the hyperactivity of PTKs. Tyrphostins are a class of antiproliferative compounds that act as PTK blockers. PTK inhibitors that preferentially inhibit the epidermal growth factor (EGF) receptor kinase block EGF-dependent cell proliferation. Protein tyrosine kinase (PTK) inhibitors are potential antiproliferative agents for diseases caused by the hyperactivity of PTKs. Tyrphostins are a class of antiproliferative compounds that act as PTK blockers. PTK inhibitors that preferentially inhibit the epidermal growth factor (EGF) receptor kinase block EGF-dependent cell proliferation. RG-13022 is an inhibitor of epidermal growth factor (EGF) receptor kinase with an IC₅₀ value of 1 μM in HT-22 cells.

(Z)-RG-13022 is a tyrosine kinase (TK) inhibitor, which inhibits preferentially the TK activity of the EGF receptor and inhibits EGF-stimulated growth of cultured cells. (Z)-RG-13022 exerts an IC50 of 11 μM for DNA synthesis in the HN5 cells, which is 3 times more potent than (E)-RG-13022 (IC50=38 μM). (Z)-RG-13022 can be used for research of breast cancer cells[1][2].

ChEBI: 3-(3,4-dimethoxyphenyl)-2-(3-pyridinyl)-2-propenenitrile is a dimethoxybenzene.
