    Abstract

    Autotaxin produces the bioactive lipid lysophosphatidic acid (LPA), and is a drug target of considerable interest for numerous pathologies. We report the expedient, structure-guided evolution of weak physiological allosteric inhibitors (bile salts) into potent competitive Autotaxin inhibitors that do not interact with the catalytic site. Functional data confirms that our lead compound attenuates LPA mediated signalling in cells, and reduces LPA synthesis in vivo, providing a promising natural product derived scaffold for drug discovery.
