Abstact

Screening of a fragment library for PDE10A inhibitors identified a low molecular weight pyrimidine hit with PDE10A Ki of 8700 nM and LE of 0.59. Initial optimization by catalog followed by iterative parallel synthesis guided by X-ray cocrystal structures resulted in rapid potency improvements with minimal loss of ligand efficiency. Compound 15 h, with PDE10A Ki of 8.2 pM, LE of 0.49, and >5000-fold selectivity over other PDEs, fully attenuates MK-801-induced hyperlocomotor activity after ip dosing.
