| | BIBP 3226 trifluoroacetate Usage And Synthesis |
| Uses | BIBP3226 TFA is a potent and selective neuropeptide Y Y1 (NPY Y1) and neuropeptide FF (NPFF) receptor antagonist, with Kis of 1.1, 79, and 108 nM for rNPY Y1, hNPFF2, and rNPFF, respectively. BIBP3226 TFA displays anxiogenic-like effect[1][2]. | | Biological Activity | bibp 3226 trifluoroacetate is a non-peptide neuropeptide y y1 (npy y1) and neuropeptide ff (npff) receptor antagonist with ki values of 1.1, 79, 108 for rnpy y1, hnpff2, rnpff, respectively.neuropeptide y y1 receptors (npy y1) involve in the regulation of exploratory behaviour and anxiety. neuropeptide ff (npff) is a part of a neurotransmitter system functioning as a modulator of endogenous opioid functions [1].bibp 3226 was able to compete for the specific npff binding expressed in cho cells as well as in rat dorsal spinal cord. in hnpff2 receptors transfected cells, bibp 3226 (10mm) is able to antagonize the inhibition of forskolin-stimulated cyclic amp production induced by npff (10nm) in a concentration-dependent manner [2].in male wistar rats, bibp3226 at the dose of 5 mg caused an anxiogenic-like effect while the lower dose was ineffective. while, the overall locomotory activity didn’t change in all treatment groups [1]. in mice model, bibp3226 (5nmol) injected into the third ventricle completely antagonized the hypothermic effects of npff (30nmol) and npvf (30nmol). in the mouse tail-flick assay, bibp3226 (5nmol) prevented the anti-morphine actions of npff (10nmol). also, in urethane-anaesthetized rats, bibp3226 (500nmol/kg) significantly reduced the mean arterial blood pressure induced by npff (200nmol/kg) and npvf (200nmol/kg) [3]. | | in vivo | BIBP3226 (0.5, 5 μg; i.c.v.) induces an anxiogenic-like effect at the higher dose[1]. | Animal Model: | Male Wistar rats 270-350 g[1] | | Dosage: | 0.5, 5 μg | | Administration: | I.c.v | | Result: | At the dose of 5μg caused an anxiogenic-like effect while the lower dose was ineffective.
