Parallel Chemistry Approach to Identify Novel Nuclear Receptor Ligands Based on the GW0742 Scaffold
摘要:
We describe the parallel synthesis of novel analogs of GW0742, a peroxisome proliferator-activated receptor delta (PPAR delta) agonist For that purpose, modified reaction conditions were applied, such as a solid-phase palladium-catalyzed Suzuki coupling. In addition, tetrazole-based compounds were generated as a bioisostere for carboxylic acid-containing ligand GW0742. The new compounds were investigated for their ability to activate PPAR delta mediated transcription and their cross-reactivity with the vitamin D receptor (VDR), another member of the nuclear receptor superfamily. We identified many potent PPAR delta agonists that were less toxic than GW0742, where similar to 65 of the compounds synthesized exhibited partial PPAR delta activity (23-98%) with EC50 values ranging from 0.007-18.2 mu M. Some ligands, such as compound 32, were more potent inhibitors of VDR-mediated transcription with significantly reduced PPAR delta activity than GW0742, however, none of the ligands were completely selective for VDR inhibition over PPAR delta activation of transcription.

Non-ATP competitive pyrimidine-based inhibitors of CaMKIId were identified. Computational studies were enlisted to predict the probable mode of binding. The results of the computational studies led to the design of ATP competitive inhibitors with optimized hinge interactions. Inhibitors of this class possessed improved enzyme and cellular activity compared to early leads. (C) 2008 Elsevier Ltd. All rights reserved.
