Through high throughput screening and subsequent hit identification and optimization, we synthesized a series of 1-arylcarbonyl-6,7-dimethoxyisoquinoline derivatives as the first reported potent and reversible GFAT inhibitors. SAR studies of this class of compounds indicated significant impact on GFAT inhibition potency by substitutions on the A-ring and C-ring. The ketone group was found to be necessary for high potency. Compound 28 (RO0509347) demonstrated potent GFAT inhibition (IC(50) = 1 mu M) with a desirable pharmacokinetic profile in rats, and showed significant efficacy in reducing the glucose excursion in an OGTT test in ob/ob mice.
