Abstact

The identification of potent and orally active dihydroimidazoisoquinolines as PDE 10A inhibitors is reported. The SAR development led to the discovery of compound 35 as a potent, selective, and orally active PDE10A inhibitor. Compound 35 inhibited MK-801-induced hyperactivity at 3mg/kg and displayed a 10-fold separation between the minimal effective doses for inhibition of MK-801-induced hyperactivity and hypolocomotion in rats.
