AG957 is a tyrosine phosphorylation inhibitor that targets transforming Bcr-Abl fusion proteins (p185Bcr-Abl, p210Bcr-Abl), as well as normal c-Abl .
The abl proto-oncogene is expressed in all cell types. The protein p140c-abl is localized both to the nucleus and the cytoplasm. The abl transforming proteins p160gag-abl, p210bcr-abl, and p185bcr-abl are exclusively cytoplasmic proteins. The intrinsic protein tyrosine kinase activity of the transforming abl proteins is higher than that of the normal p140c-abl .
AG957 is a tyrosine phosphorylation inhibitor. AG957 inhibited human p185Bcr-Abl, p210Bcr-Abl and normal c-Abl with IC50 values of 4.3, 1, and 7.1 μM, respectively. AG957 inhibited mouse normal c-Abl with IC50 value of 6 μM. AG957 also inhibited epidermal growth factor receptor with IC50 value of 0.25 μM. In chronic myelogenous leukemia (CML) K562 cells, AG957 inhibited p210bcr-abl kinase activity and cell growth. AG957 at 20 μM also inhibited DNA synthesis as early as 2 h by 60% . In K562 cells, AG957, a selective Bcr-Abl inhibitor, blocked taxol-induced PKCi activation and sensitized these cells to taxol-induced apoptosis .
In mice, AG957, the c-Abl inhibitor, attenuated LPS-induced pulmonary permeability .
