77-LH-28-1 Oxalate is a salt of 77-LH-28-1. This drug is a potent, selective, bioavailable and brain-penetrant agonist of muscarinic acetylcholine receptor subtype 1. 77-LH-28-1 can increase network oscillations relevant to cognitive processing that would support the potential use of this mechanism in the treatment of cognitive impairment. 77-LH-28-1 exhibited U-shaped dose-effect functions in attenuating cocaine discrimination. 77-LH-28-1, can significantly enhance donepezil-induced gamma oscillations. These data support the notion that it should be possible to find a more efficacious AChE inhibitor or an adjunctive approach, to provide a better therapeutic intervention in Alzheimer's disease.
