Pathological angiogenesis plays a critical role in numerous diseases including malignancy. VEGFR-2 is the central regulators in angiogenesis and has become a promising target for anticancer drug design. We have identified a novel biphenyl-aryl urea incorporated with salicyladoxime (BPS-7) as potent VEGFR-2 inhibitor. As a continuation to our previous research, various aromatic-heterocyclic were introduced as hinge-binding fragment via a core-refining approach. Interestingly, many compounds exhibited comparable VEGFR-2 inhibition to Sorafenib. In particular, 12e and 12o displayed excellent VEGFR-2 inhibitory activity with IC50 values of 0.50 nM and 0.79 nM, respectively. Several title compounds showed considerable antiproliferative activity against A549 and SMMC-7721 cells. In addition, molecular docking was performed to rationalize the efficiency of the better compounds. These results will be instructive for further inhibitor design and optimization.

Optimization of a new series of small molecule human glucagon receptor (hGluR) antagonists is described. In the process of optimizing glucagon receptor antagonists, we counter-screened against the closely related human gastric inhibitory polypeptide receptor (hGIPR), and through structure activity analysis, we obtained compounds with low nanomolar affinities toward the hGluR, which were selective against the hGIPR and the human glucagon-like peptide-1 receptor (hGLP-1R). In the best cases, we obtained a >50 fold selectivity for the hGluR over the hGIPR and a >1000 fold selectivity over the hGLP-1R. A potent and selective glucagon receptor antagonist was demonstrated to inhibit glucagon-induced glycogenolysis in primary rat hepatocytes as well as to lower glucagon-induced hyperglycemia in Sprague - Dawley rats. Furthermore, the compound was shown to lower blood glucose in the ob/ob mouse after oral dosing.

Disclosed is a novel class of compounds of formula (I) wherein V, A, Y, Z, R1, E, X and D are as defined in the specification. These compounds act to antagonize the action of the glucagon hormone on the glucagon receptor. Owing to their antagonizing effect of the glucagon receptor, the compounds are suitable for treating or preventing glucagon-mediated conditions and diseases such as hyperglycemia, Type 1 diabetes, Type 2 diabetes and obesity.
