Background

XL228, a tyrosine kinase inhibitor, is involved in binding to and inhibiting the activities of multiple tyrosine kinases, such as the insulin-like growth factor 1 receptor (IGF1R), Src tyrosine kinase, and Bcr-Abl tyrosine kinase. Blockade of these kinases may result in the inhibition of tumor angiogenesis, cell proliferation, and metastasis [1]. XL228 is a multitargeted protein kinase inhibitor targeting IGF1R, the aurora kinases, IGF-1R, cSrc, BCR/Abl and SRC kinases [2].

In vitro: XL228(5-100 nM) reduced cell survival by 10-70% in a dose and time dependent manner and inhibited migration and invasion of two tumors with high propensity to metastasize, FaDu and H460. Treatment with 50 and 100 nM XL228 abolished the ability of H460, A549 and FaDu cells to form colony. At 10 nM, XL228 significantly increased the radiosensitivity of H460, A549 and FaDu cells by enhancement factors (EF, at the survival fraction of 0.5) of 1.52, 1.31 and 1.67 respectively. But, In HN-5 cells, sensitization occurred only at 100 nM (EF = 2.27). In HN-5 cells, XL228 (100 nM)incubation induced accumulation of cells at the radiation sensitive G2/M phase of the cell cycle and induced apoptosis in 32% of cells [2].

Clinical trial: In a phase I study in patients with solid tumors or hematologic malignancies, XL228 showed a manageable toxicity profile and biological activity through decrease in target pathway and alternations in tumor nuclei [3].
