  • PubMed Abstract: 

    Lp-PLA 2 has been explored as a target for a number of inflammation associated diseases, including cardiovascular disease and dementia. This article describes the discovery of a new fragment derived chemotype that interacts with the active site of Lp-PLA 2 . The starting fragment hit was discovered through an X-ray fragment screen and showed no activity in the bioassay (IC 50 > 1 mM). The fragment hit was optimized using a variety of structure-based drug design techniques, including virtual screening, fragment merging, and improvement of shape complementarity. A novel series of Lp-PLA 2 inhibitors was generated with low lipophilicity and a promising pharmacokinetic profile.
