title: Different behavioral profiles of the non-peptide substance P (NK1) antagonists CP-96,345 and RP 67580 in Swiss albino mice in the black-and-white box.
abstract: The non-peptide NK1 antagonists, RP 67580, and (2S,3S)-CP-96,345, the NK1 receptor-selective enantiomer of the racemic compound, were tested in Swiss albino mice in the black-and-white box behavioral paradigm. Both qualitatively and quantitatively, (2S,3S)-CP-96,345 produced the same behavioral effects as the racemic compound. In contrast, RP 67580 decreased exploratory behavior only in the white section, whereas crossings and rearings in the black section were not changed. In addition, RP 67580 decreased transitions. While the observed changes induced by CP-96,345 are caused by sedation and motor impairment, the effects of RP 67580 might be due to sedation plus an additional anxiogenic effect.
