Biochem/physiol Actions

Perospirone (SM-9018) is a typical neuroleptic (antipsychotic) agent that displays high affinity for 5-HT2, D2 and 5-HT1A receptors (Ki = 0.61, 1.4 and 2.9-1.8 nM, respectively), moderate affinity for alpha 1 and D1 receptors (Ki = 17 and 41 nM, respectively), while exhibiting much reduced affinity for alpha 2 (Ki = 408 nM) and little affinity toward muscarinic, opiate, glutamate, phencyclidine, benzodiazepine or GABAA receptors (Ki >1 μM). SM-9018 antagonizes both D2-dependent (e.g. methamphetamine-induced hyperactivity, apomorphine-induced stereotypy) and 5-HT2-mediated (e.g. tryptamine-induced clonic seizure) activities in vivo, while exhibiting very low cataleptogenic and central depressant activities commonly observed with two other neuroleptics, haloperidol and chlorpromazine.

Induction of bradykinesia by SM-9018, a novel 5-HT2 and D2 antagonist, was compared with that of other neuroleptics using the pole test in mice. Neuroleptics including SM-9018, haloperidol, chlorpromazine, and thioridazine dose dependently induced bradykinesia in the pole-descending behavior of

Pharmacological studies were undertaken to clarify the profile of cis-2-(4-(4-(1,2-benzisothiazol-3-yl)-1-piperazinyl) butyl) hexahydro-1H-isoindole-1,3-(2H)-dione hydrochloride (SM-9018), a new neuroleptic drug. SM-9018 had very high binding affinities for both 5-hydroxytryptamine2 (5-HT2) and dopamine2 (D2) receptors, unlike many other neuroleptics. SM-9018 also strongly inhibited

1. Changes in behavioral dopaminergic and serotonergic sensitivities were studied in rats after withdrawal of the chronic treatments with SM-9018 (0.1 mg/kg/day), a potential atypical neuroleptic, and with haloperidol (0.3 mg/kg/day) using continuous infusion pumps. 2. Administration of SM-9018 inhibited

The effects of SM-9018, a potential atypical neuroleptic, on monoamine metabolism were studied in rats. SM-9018 dose-dependently increased the levels of 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) in the cerebral cortex and striatum without affecting the levels of 5-HT
T Kato et al.
Japanese journal of pharmacology, 54(4), 478-481 (1990-12-01)
The present study employed various receptor-binding assays to clarify the biochemical characteristics of SM-9018. SM-9018 possessed very high affinity for 5-HT2, D2 and 5-HT1A receptors (Ki = 0.61, 1.4 and 2.9 nM, respectively), and it had moderate affinity for alpha
