Spiramide (AMI-193) is a potent and selective antagonist of 5-HT2 and dopamine D2 receptor, with Kis of 2 nM and 3 nM, respectively. Spiramide has >2000-fold selectivity for 5-HT2 versus 5-HT1C (Ki=4300 nM) receptors. Spiramide exhibits antipsychotic activity[1][2][3].

Description	Spiramide (AMI-193) is a potent and selective antagonist of 5-HT2 and dopamine D2 receptor, with Kis of 2 nM and 3 nM, respectively. Spiramide has >2000-fold selectivity for 5-HT2 versus 5-HT1C (Ki=4300 nM) receptors. Spiramide exhibits antipsychotic activity[1][2][3].

Target	5-HT2 Receptor:2 nM (Ki) D2 Receptor:3 nM (Ki) 5-HT1A Receptor:50 nM (Ki) D1 Receptor:2530 nM (Ki) 5-HT1C Receptor:4300 nM (Ki)
In Vitro	Spiramide retains affinity for 5-HT1A sites (Ki=50 nM) and also binds at dopamine D2 sites (Ki=3 nM), but possesses low affinity for dopamine D1 sites (Ki=2530 nM)[1].
In Vivo	AMI-193 (0.003-0.01 mg/kg; i.m.) dose-dependently decreases response rate in monkeys under a fixed-interval (FI) schedule of stimulus termination[2]. AMI-193 (0.003-0.01 mg/kg; i.m.) attenuates the discriminative-stimulus effects of cocaine in drug-discrimination experiments[2]. AMI-193 (0.003-0.01 mg/kg; i.m.) reduces response rate under a second-order schedule of i.v. self-administration of cocaine (0.1 mg/infusion)[2]. Animal Model: Adult male squirrel monkeys (850-1300 g)[2] Dosage: 0.003, 0.01 mg/kg Administration: I.m. on Tuesday, Wednesday, and Thursday the following week Result: Decreased the response rate. The rate-decreasing effects were reversed by cocaine.
