• Saracatinib is an orally available Src kinase inhibitor.
• Saracatinib inhibits c-Src and Abl enzymes at low nanomolar concentrations. Saracatinib blocked the tumor growth of a c-Src-transfected 3T3-fibroblast xenograft in vivo and increased significantly the survival of animals in a highly aggressive model of human pancreatic cancer. Hennequin, L.F., et al. "N-(5-chloro-1,3-benzodioxol-4-yl)-7-[2-(4-methylpiperazin-1-yl)ethoxy]-5- (tetrahydro-2H-pyran-4-yloxy)quinazolin-4-amine, a novel, highly selective, orally available, dual-specific c-Src/Abl kinase inhibitor." J. Med. Chem. 49: 6465-6488 (2006).
• Saracatinib blocked the proliferation of various cell lines tested (IC50 = 0.2 - >10 µM) and inhibited tumor growth in 4/10 xenograft models tested. Saracatinib had significant antimigratory and anti-invasive effects in vitro, and inhibited metastasis of bladder cancer in vivo. Saracatinib blocked phosphorylation of Src substrates paxillin and FAK in both growth-inhibition-resistant and -sensitive xenografts. Green, T.P., et al. "Preclinical anticancer activity of the potent, oral Src inhibitor AZD0530." Mol. Oncol. 3: 248-261 (2009).
• Saracatinib blocked the growth of, and induced apoptosis in, chronic myeloid leukaemia (CML) and Ph+ acute lymphoblastic leukaemia (ALL) cells, but showed only slight effects on Ph- ALL cells. Saracatinib overcame the resistance to imatinib due to the mutation Y253F in p185Bcr-Abl. Combination treatment of saracatinib and imatinib showed an additive inhibitory effect on the proliferation of CML BV173 cells but not on Ph+ ALL SupB15 cells. Gwanmesia, P.M., et al. "The effect of the dual Src/Abl kinase inhibitor AZD0530 on Philadelphia positive leukaemia cell lines." BMC Cancer 9: 53 (2009).
• Saracatinib inhibited the anchorage-dependent growth of MCF-7 with IC50 of 0.47 µM, which was increased 4-fold in the presence of estrogen. In contrast, saracatinib inhibited the growth of cells stably expressing the mutant ERα with an elevated IC50 that was only increased 1.4-fold by estrogen stimulation. The results indicated that c-Src inhibition is blocked by estrogen signaling. Herynk, M.H., et al. "Cooperative action of tamoxifen and c-Src inhibition in preventing the growth of estrogen receptor-positive human breast cancer cells." Mol. Cancer Ther. 5: 3023-3031 (2006).
• Saracatinib inhibited the proliferation of DU145 and PC3 prostate cancer cells, apparently by reducing binding of beta-catenin to the promoters of G1 phase cell cycle regulators cyclin D1 and c-Myc. Saracatinib also decreased orthotopic DU145 xenograft growth by 45% in mice. Chang, Y.M., et al. "Src family kinase oncogenic potential and pathways in prostate cancer as revealed by AZD0530." Oncogene 27: 6365-6375 (2008).
• Saracatinib treatment is feasible and tolerable in previously treated patients suffering from advanced castration-resistant prostate cancer, but it had little clinical efficacy as monotherapy.
