AMI-193 is a potent and selective antagonist of 5-HT2A receptor and dopamine D2-receptor with Ki values of 2 and 3 nM, respectively [1].
The 5-HT2A receptor is a G protein-coupled receptor and a subtype of the 5-HT2 receptor. The 5-HT2A receptor plays an important role in the spread of the human polyoma virus. The dopamine D2-receptor is a G protein-coupled receptor that inhibits adenylyl cyclase activity.
AMI-193 is a potent and selective 5-HT2A receptor and dopamine D2-receptor antagonist. AMI-193 was highly selective for 5-HT2A versus 5-HT2C receptor with Ki values of 2 and 4300 nM for 5-HT2A and 5-HT2C receptor, respectively [1]. Also, AMI-193 bound to 5-HT2 receptor with Ki value of 2 nM and exhibited >2000-fold selectivity versus 5-HT1C receptor. In cortical slices, AMI-193 (10-10 - 10-5 M) inhibited GABA release in a dose-dependent way and increased 5-HT outflow [3].
In rats, AMI-193 behaved as an antagonist with ED50 value of 0.003 mg/kg [2].
