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.

The free fatty acid receptor 1 (FFA1) has attracted extensive attention as a novel antidiabetic target in the last decade. Several FFA1 agonists reported in the literature have been suffered from relatively high molecular weight and lipophilicity. We have previously reported the FFA1 agonist 1. Based on the common amide structural characteristic of SAR1 and NIH screened compound, we here describe the continued structure-activity exploration to decrease the molecular weight and lipophilicity of the compound 1 series by converting various amide linkers. All of these efforts lead to the discovery of the preferable lead compound 18, a compound with considerable agonistic activity, high LE and LLE values, lower lipophilicity than previously reported agonists, and appreciable efficacy on glucose tolerance in both normal and type 2 diabetic mice.
