- Structure-activity relationship studies for the development of inhibitors of murine adipose triglyceride lipase (ATGL)
-
High serum fatty acid (FA) levels are causally linked to the development of insulin resistance, which eventually progresses to type 2 diabetes and non-alcoholic fatty liver disease (NAFLD) generalized in the term metabolic syndrome. Adipose triglyceride lipase (ATGL) is the initial enzyme in the hydrolysis of intracellular triacylglycerol (TG) stores, liberating fatty acids that are released from adipocytes into the circulation. Hence, ATGL-specific inhibitors have the potential to lower circulating FA concentrations, and counteract the development of insulin resistance and NAFLD. In this article, we report about structure–activity relationship (SAR) studies of small molecule inhibitors of murine ATGL which led to the development of Atglistatin. Atglistatin is a specific inhibitor of murine ATGL, which has proven useful for the validation of ATGL as a potential drug target.

- Discovery of biphenyl-aryl ureas as novel VEGFR-2 inhibitors. Part 4: Exploration of diverse hinge-binding fragments
-
Abstract VEGFR-2 plays an essential role in angiogenesis and is an important target for cancer therapy. A series of biphenyl-aryl ureas were synthesized and evaluated as novel VEGFR-2 inhibitors. The pyridine, methylamine carbonyl pyridine and pivaloyl amide pyridine were introduced as novel hinge binding fragment. The majority of title compounds displayed potent VEGFR-2 inhibition. In particular, L1, L9, W14 and W15 exhibited significant enzymatic inhibitory activity with IC50 values of 0.36 nM, 0.22 nM, 0.15 nM and 0.14 nM. Compounds L1, L9 and W15 displayed potent antiproliferative activity against A549 and SMMC-7721 cells. SAR study suggested that incorporation of 3-trifluoromethyl and methylamine carbonyl on terminal pyridine could improve VEGFR-2 inhibitory activity. Molecular docking illustrated that urea moiety formed two critical hydrogen bonds with the DFG residues of VEGFR-2. The results indicated that these biphenyl-aryl ureas could serve as promising lead compounds for further optimization.
