The 5-HT(1A) receptor antagonist robalzotan completely reverses citalopram-induced inhibition of serotonergic cell firing.[Pubmed:10528148]
Eur J Pharmacol. 1999 Oct 8;382(2):133-8.
5-HT(1A) receptor antagonists have been suggested to increase the efficacy of selective serotonin (5-hydroxytryptamine; 5-HT) reuptake inhibitors in the treatment of depression by enhancing the increase in brain 5-HT induced by 5-HT reuptake blockade. Here, the novel 5-HT(1A) receptor antagonist robalzotan [(R)-3-N, N-dicyclobutylamino-8-fluoro-3, 4-dihydro-2H-1-benzopyran-5-carboxamide hydrogen (2R, 3R) tartrate monohydrate] (12.5, 25, 50, 100 microg/kg, i.v.) was found to completely reverse the acute inhibitory effect of citalopram (300 microg/kg i.v.) or paroxetine (100 microg/kg, i.v.) on the activity of 5-HT neurons in the dorsal raphe nucleus in rats. Robalzotan (5, 50 microg/kg, i.v.) by itself increased the firing rate of the majority of 5-HT cells studied. The present results suggest that robalzotan may indeed augment the increases in 5-HT output induced by selective 5-HT reuptake inhibitors by antagonizing the feedback inhibition of 5-HT cell firing produced by such drugs. Thus, robalzotan may be effective by enhancing the action of selective 5-HT reuptake inhibitors or as monotherapy in the treatment of depression.
Differential regional antagonism of 8-OH-DPAT-induced decrease in serotonin synthesis by two 5-HT1A receptor antagonists.[Pubmed:9652362]
Eur J Pharmacol. 1998 Apr 10;346(2-3):209-15.
The effects of two 5-HT1A receptor antagonists, (R)-3-N, N-dicyclobutylamino-8-fluoro-3,4-dihydro-2 H-1-benzopyran-5-carboxamide hydrogen (2 R,3 R)-tartrate monohydrate (NAD-299) and N-(2-(1-(2-methoxyphenyl)-piperazinyl))ethyl)-N-(2-pyridinyl) cyclohexanecarboxamide trihydrochloride (WAY-100635) on the decrease in 5-hydroxytryptophan (5-HTP) accumulation evoked by (RS)-2-dipropylamino-8-hydroxy-1,2,3,4-tetrahydronaphthalene (8-OH-DPAT) in rats treated with the decarboxylase inhibitor, 3-hydroxyphenylhydrazine (NSD 1015) were studied in four rat brain regions: hippocampus, hypothalamus, striatum and frontal cortex. Dose-response studies revealed differential effects of both antagonists in the areas examined. Both antagonists were significantly more potent in antagonising the effect of 0.30 and 0.76 micromol/kg s.c. 8-OH-DPAT in hippocampus than in hypothalamus, striatum and frontal cortex in mentioned order. This order of potency was the opposite to that found for 8-OH-DPAT in decreasing the 5-HTP accumulation. Since previous studies by others have indicated that the reserve of somatodendritic 5-HT1A receptors is greater in dorsal raphe nucleus innervating frontal cortex and striatum than in median raphe nucleus which mainly innervates hippocampus, the observed different regional potency of the two 5-HT1A receptor antagonists may be explained by this difference in the 5-HT1A receptor reserve.
