1.Antidepressant-like activity of the neuropeptide Y Y5 receptor antagonist Lu AA33810: behavioral, molecular, and immunohistochemical evidence.

RATIONALE: ;It has recently been found that chronic treatment with the highly selective, brain-penetrating Y5 receptor antagonist, Lu AA33810 [N-[[trans-4-[(4,5-dihydro [1] benzothiepino[5,4-d] thiazol-2-yl) amino] cyclohexyl]methyl]-methanesulfonamide], produces antidepressant-like effects in the rat chronic mild stress model.;OBJECTIVE: ;In the present study, we investigated the possible antidepressant-like activity of Lu AA33810 in rats subjected to glial ablation in the prefrontal cortex (PFC) by the gliotoxin L-AAA, which is an astroglial degeneration model of depression.;RESULTS: ;We observed that Lu AA33810 administered intraperitoneally at a single dose of 10 mg/kg both reversed depressive-like behavioral changes in the forced swim test (FST) and prevented degeneration of astrocytes in the mPFC. The mechanism of antidepressant and glioprotective effects of Lu AA33810 has not been studied, so far. We demonstrated the contribution of the noradrenergic rather than the serotonergic pathway to the antidepressant-like action of Lu AA33810 in the FST. Moreover, we found that antidepressant-like effect of Lu AA33810 was connected with the influence on brain-derived neurotrophic factor (BDNF) protein expression.
2.The novel neuropeptide Y Y5 receptor antagonist Lu AA33810 [N-[[trans-4-[(4,5-dihydro[1]benzothiepino[5,4-d]thiazol-2-yl)amino]cyclohexyl]methyl]-methanesulfonamide] exerts anxiolytic- and antidepressant-like effects in rat models of stress sensitivity.

Neuropeptide Y (NPY) regulates physiological processes via receptor subtypes (Y(1), Y(2), Y(4), Y(5), and y(6)). The Y(5) receptor is well known for its role in appetite. Based on expression in the limbic system, we hypothesized that the Y(5) receptor might also modulate stress sensitivity. We identified a novel Y(5) receptor-selective antagonist, Lu AA33810 [N-[[trans-4-[(4,5-dihydro[1]-benzothiepino[5,4-d]thiazol-2-yl)amino]cyclohexyl]methyl]-methanesulfonamide], that bound to cloned rat Y(5) receptors (K(i) = 1.5 nM) and antagonized NPY-evoked cAMP and calcium mobilization in vitro. Lu AA33810 (3-30 mg/kg p.o.) blocked feeding elicited by intracerebroventricular injection of the Y(5) receptor-selective agonist [cPP(1-7),NPY(19-23),Ala(31),Aib(32),Gln(34)]-hPancreatic Polypeptide in Sprague-Dawley rats. In vivo effects of Lu AA33810 were correlated with brain exposure > or = 50 ng/g and ex vivo Y(5) receptor occupancy of 22 to 95%. Lu AA33810 was subsequently evaluated in models of stress sensitivity. In Fischer 344 rats, Lu AA33810 (30 mg/kg p.o.) attenuated increases in plasma ACTH and corticosterone elicited by intracerebroventricular injection of [cPP(1-7),NPY(19-23),Ala(31),Aib(32),Gln(34)]-hPancreatic Polypeptide.
