- Synthesis and anti-tumor activity of [1,4] dioxino [2,3-f] quinazoline derivatives as dual inhibitors of c-Met and VEGFR-2
-
Both c-Met and VEGFR-2 were important targets for cancer therapies. In order to develop reversible and non-covalent c-Met and VEGFR-2 dual inhibitors, a series of [1,4]dioxino[2,3-f]quinazoline derivatives were designed and synthesized. The enzyme assay demonstrated that most target compounds had inhibition potency on both c-Met and VEGFR-2 with IC50 values in nanomolar range especially compounds 7m and 7k. Based on further cell proliferation assay in vitro, compound 7k showed significantly anti-tumor activity in vivo on a hepatocellular carcinoma (MHCC97H cells) xenograft mouse model. We docked the compound 7m with c-Met and VEGFR-2 kinases, and interpreted the SAR of these analogues. All results indicated that the target compounds were dual inhibitors of c-Met and VEGFR-2 kinases that held promising potential in cancer therapy.

- Exploration of novel pyrrolo[2,1-f][1,2,4]triazine derivatives with improved anticancer efficacy as dual inhibitors of c-Met/VEGFR-2
-
c-Met and VEGFR-2 have attracted interest as novel targets for treatment of various cancers. Aiming to develop potent dual c-Met and VEGFR-2 inhibitors, a series of pyrrolo[1,2-f][1,2,4]triazine derivatives were designed and synthesized. The majority of target compounds exhibited potent antiproliferative effect against c-Met addictive cancer cell lines with IC50 values ranged from 1.2 to 24.6 nM, especially 27a. In-depth studies demonstrated 27a has great selectivity to c-Met and VEGFR-2, and potent inhibitory activity against them (IC50 of 2.3 ± 0.1 nM and 5.0 ± 0.5 nM). Furthermore, it also showed the highest anticancer activity with IC50 of 0.71 ± 0.16 nM (better than the positive compound) against BaF3-TPR-Met and 37.4 ± 0.311 nM (comparable to the positive compound) against HUVEC-VEGFR2, consistent with that in c-Met sensitive tumor cell lines. Subsequently, physicochemical and pharmacokinetic characterization indicated 27a has favorable druggability and pharmacokinetic properties. Further docking studies suggested a common mode of interaction at the ATP-binding site of c-Met and VEGFR-2, also indicating that 27a was a potential candidate for cancer therapy deserving further study.

- Synthesis and biological evaluation of novel 6,11-dihydro-5H-benzo[e]pyrimido- [5,4-b][1,4]diazepine derivatives as potential c-Met inhibitors
-
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.

The cell proliferation assay in vitro demonstrated that most target compounds had inhibition potency both on c-Met and VEGFR-2 with IC50 values in nanomolar range, especially compound 12j and 12m. Based on the further enzyme assay in vitro, compound 12j was considered as the most potent one, the IC50 values of which were 25 nM and 48 nM for c-Met and VEGFR-2, respectively. Following that, we docked the compound 12j with the proteins c-Met and VEGFR-2, and interpreted the SAR of these analogues. All the results indicate that 12j is a dual inhibitors of c-Met and VEGFR-2 that holds promising potential.

The synergistically collaboration of c-Met/HGF and VEGFR-2/VEGF leads to development of tumor angiogenesis and progression of various human cancers. Therefore, inhibiting both HGF/c-Met and VEGF/VEGFR signaling may provide a novel and effective therapeutic approach for treating patients with abroad spectrum of tumors. Toward this goal, we designed and synthesized a series of derivatives bearing 4-aminopyrimidine-5-cabaldehyde oxime scaffold as potent dual inhibitors of c-Met and VEGFR-2. The cell proliferation assay in vitro demonstrated most target compounds have inhibition potency both on c-Met and VEGFR-2 with IC50values in nanomolar range, especially compound 14i, 18a and 18b. Based on the further enzyme assay in vitro, compound 18a was considered as the most potent one, the IC50s of which were 210?nM and 170?nM for c-Met and VEGFR-2, respectively. Following that, we docked the compound 10 and 18a with the proteins c-Met and VEGFR-2, and interpreted the SAR of these analogs. All the results indicate that 18a is a dual inhibitors of c-Met and VEGFR-2 that holds promising potential.

- Discovery of potent c-MET inhibitors with new scaffold having different quinazoline, pyridine and tetrahydro-pyridothienopyrimidine headgroups
-
Cellular mesenchymal-epithelial transition factor (c-MET) is closely linked to human malignancies, which makes it an important target for treatment of cancer. In this study, a series of 3-methoxy-N-phenylbenzamide derivatives, N-(3-(tert-butyl)-1-phenyl-1H-pyrazol-5-yl) benzamide derivatives and N1-(3-fluoro-4-methoxyphenyl)-N3-(4-fluorophenyl) malonamide derivatives were designed and synthesized, some of them were identified as c-MET inhibitors. Among these compounds with new scaffolds having different quinazoline, pyridine and tetrahydro-pyridothienopyrimidine head groups, compound 11c, 11i, 13b, 13h exhibited both potent inhibitory activities against c-MET and high anticancer activity against tested cancer cell lines in vitro. In addition, kinase selectivity assay further demonstrated that both 13b and 13h are potent and selective c-MET inhibitors. Molecular docking supported that they bound well to c-MET and VEGFR2, which demonstrates that they are potential c-MET RTK inhibitors for cancer therapy.
