Over expression of c-Met tyrosine kinase is known to promote tumorigenesis and metastasis, as well as to cause therapeutic resistance. Herein a series of novel 6,11-dihydro-5H-benzo[e]pyrimido[5,4-b][1,4]diazepine derivatives were designed, synthesised and evaluated for their c-Met kinase inhibition. Compounds 17e, 17f, 18a, and 18b were further examined for their anti-proliferative activities against four typical cancer cell lines (PC-3, Panc-1, HepG2, and Caki-1). The promising compound 17f was identified as a multi-target receptor tyrosine kinase inhibitor, which also displayed favourable pharmacokinetic properties in rats, had an acceptable safety profile in preclinical studies, and significant anti-tumour activity in the Caki-1 tumour xenograft model.
