  • PubMed Abstract: 

    A papaverine based pharmacophore model for PDE10A inhibition was generated via SBDD and used to design a library of 4-amino-6,7-dimethoxyquinazolines. From this library emerged an aryl ether pyrrolidyl 6,7-dimethoxyquinazoline series that became the focal point for additional modeling, X-ray, and synthetic efforts toward increasing PDE10A inhibitory potency and selectivity versus PDE3A/B. These efforts culminated in the discovery of 29, a potent and selective brain penetrable inhibitor of PDE10A.
