  • Title: Sigma1 receptor subtype does not interact with stereotyped behaviors in rats.
    Author: Kobayashi T, Matsuno K, Mita S.
    Journal: Pharmacol Biochem Behav; 1998 Dec; 61(4):381-4. PubMed ID: 9802832.
    Abstract:
    In the present study, we clearly showed that the sigma1 receptor subtype did not interact with the induction of stereotyped behaviors in rats. Namely, (+)-N-allylnormetazocine [(+)-SKF-10,047] (5.0, 10.0, and 20.0 mg/kg, SC), a traditional sigma receptor ligand that has affinities for the sigma1 receptor subtype and the N-methyl-D-aspartate (NMDA)/phencyclidine (PCP) receptor channel complex, markedly produced PCP-like stereotyped behaviors, such as head weaving, turning, and backpedaling, in rats. On the contrary, 1-(3,4-dimethoxyphenyl)-4-(3-phenylpropyl)piperazine dihydrochloride (SA4503), a potent and selective sigma1 receptor agonist, did not produce these behaviors. Additionally, PCP-induced stereotyped behaviors were significantly augmented by (+)-SKF-10,047, but not by SA4503. We thus suggest that the induction of PCP-like stereotyped behaviors elicited by (+)-SKF-10,047 closely interacts with NMDA/PCP receptor channel complex but not with the sigma1 receptor subtype.
