Role of peripheral and spinal 5-HT6 receptors according to the rat formalin test
Neuroscience 2009 Aug 18;162(2):444-52.PMID:19422883DOI:10.1016/j.neuroscience.2009.04.072.
The present study assessed the possible pronociceptive role of peripheral and spinal 5-HT(6) receptors in the formalin test. For this, local peripheral administration of selective 5-HT(6) receptor antagonists N-[3,5-dichloro-2-(methoxy)phenyl]-4-(methoxy)-3-(1-piperazinyl)-benzenesulphonamide (SB-399885) (0.01-1 nmol/paw) and 4-iodo-N-[4-methoxy-3-(4-methyl-1-piperazinyl)phenyl]benzene-sulfonamide hydrochloride (SB-258585) (0.001-0.1 nmol/paw) significantly reduced formalin-induced flinching. Local peripheral serotonin (5-HT) (10-100 nmol/paw) or 5-chloro-2-methyl-3-(1,2,3,6-tetrahydro-4-pyridinyl)-1H-indole hydrochloride (EMD-386088) (0.01-0.1 nmol/paw; a selective 5-HT(6) receptor agonist) augmented 0.5% formalin-induced nociceptive behavior. The local pronociceptive effect of 5-HT (100 nmol/paw) or EMD-386088 (0.1 nmol/paw) was significantly reduced by SB-399885 or SB-258585 (0.1 nmol/paw). In contrast to peripheral administration, intrathecal injection of 5-HT(6) receptor antagonists SB-399885 and SB-258585 (0.1-10 nmol/rat) did not modify 1% formalin-induced nociceptive behavior. Spinal 5-HT (50-200 nmol/rat) significantly reduced formalin-induced flinching behavior during phases 1 and 2. Contrariwise, intrathecal EMD-386088 (0.1-10 nmol/rat) dose-dependently increased flinching during phase 2. The spinal pronociceptive effect of EMD-386088 (1 nmol/rat) was reduced by SB-399885 (1 nmol/rat) and SB-258585 (0.1 nmol/rat). Our results suggest that 5-HT(6) receptors play a pronociceptive role in peripheral as well as spinal sites in the rat formalin test. Thus, 5-HT(6) receptors could be a target to develop analgesic drugs.
Serotonin receptors in rat jugular vein: presence and involvement in the contraction
J Pharmacol Exp Ther 2010 Jul;334(1):116-23.PMID:20378714DOI:10.1124/jpet.109.163014.
Serotonin (5-hydroxytryptamine; 5-HT) is released during platelet aggregation, a phenomenon commonly observed in blood clot formation and venous diseases. Once released, 5-HT can interact with its receptors in the peripheral vasculature to modify vascular tone. The goal of this study was to perform a detailed pharmacological characterization of the 5-HT receptors involved in the contractile response of the rat jugular vein (RJV) using recently developed drugs with greater selectivity toward 5-HT receptor subtypes. We hypothesized that, as for other blood vessels, the 5-HT(1B/1D) and 5-HT(2B) receptor subtypes mediate contraction in RJV alongside the 5-HT(2A) receptor subtype. Endothelium-intact RJV rings were set up in an isolated organ bath for isometric tension recordings, and contractile concentration-effect curves were obtained for 13 distinct serotonergic receptor agonists. Surprisingly, the 5-HT(1A) and the mixed 5-HT(1A/1B) receptor agonists (+/-)-2-dipropyl-amino-8-hydroxyl-1,2,3,4-tetrahydronapthalene (8-OH-DPAT) and 5-methoxy-3 (1,2,3,6-tetrahydropyridin-4-yl) (1H indole) (RU24969) caused contractions that were antagonized by the 5-HT(1A) receptor antagonist [O-methyl-3H]-N-(2-(4-(2-methoxyphenyl)-1-piperazinyl)ethyl)-N-(2-pyridinyl)cyclohexanecarboxamide (WAY100135). The contractile curve to 5-HT was shifted to the right by WAY100135, 3-[2-[4-(4-fluoro benzoyl)-piperidin-1-yl]ethyl]-1H-quinazoline-2,4-dione (ketanserin; 5-HT(2A/C) receptor antagonist), and 1-(2-chloro-3,4-dimethoxybenzyl)-6-methyl-1,2,3,4-tetrahydro-9H-pyrido[3,4-b]indole hydrochloride (LY266097; 5-HT(2B) receptor antagonist). Ketanserin also caused rightward shifts of the contractile curves to 8-OH-DPAT, RU24969, and the 5-HT(2B) receptor agonist (alpha-methyl-5-(2-thienylmethoxy)-1H-indole-3-ethanamine) (BW723C86). Agonists for 5-HT(1B/1D/1F), 5-HT(3), 5-HT(6), and 5-HT(7) receptors were inactive. In real-time polymerase chain reaction experiments that have never been performed in this tissue previously, we observed mRNA expression for the 5-HT(2A), 5-HT(2B), and 5-HT(7) receptors, whereas no significant mRNA expression was found for 5-HT(1A), 5-HT(1B), and 5-HT(1D) receptors. These results support the 5-HT(2A) receptor as the main subtype targeted by 5-HT to contract the RJV.
Peripheral and spinal 5-HT receptors participate in the pronociceptive and antinociceptive effects of fluoxetine in rats
Neuroscience 2013 Nov 12;252:396-409.PMID:23994595DOI:10.1016/j.neuroscience.2013.08.022.
The role of 5-HT receptors in fluoxetine-induced nociception and antinociception in rats was assessed. Formalin produced a typical pattern of flinching and licking/lifting behaviors. Local peripheral ipsilateral, but not contralateral, pre-treatment with fluoxetine (0.3-3 nmol/paw) increased in a dose-dependent fashion 0.5% formalin-induced nociception. In contrast, intrathecal pretreatment with fluoxetine (0.3-3 nmol/rat) prevented nociception induced by formalin. The peripheral pronociceptive effect of fluoxetine was prevented by the 5-HT2A (ketanserin, 3-10 pmol/paw), 5-HT2B (3-(2-[4-(4-fluorobenzoyl)-1-piperidinyl]ethyl)-2,4(1H,3H)-quinazolinedione(+) tartrate, RS-127445, 3-10 pmol/paw), 5-HT2C (8-[5-(2,4-dimethoxy-5-(4-trifluoromethylphenylsulphonamido) phenyl-5-oxopentyl]1,3,8-triazaspiro[4.5] decane-2,4-dione hydrochloride, RS-102221, 3-10 pmol/paw), 5-HT3 (ondansetron, 3-10 nmol/paw), 5-HT4 ([1-[2-methylsulphonylamino ethyl]-4-piperidinyl]methyl 1-methyl-1H-indole-3-carboxylate, GR-113808, 3-100 fmol/paw), 5-HT6 (4-iodo-N-[4-methoxy-3-(4-methyl-1-piperazinyl)phenyl]benzene-sulfonamide hydrochloride, SB-258585, 3-10 pmol/paw) and 5-HT7 ((R)-3-(2-(2-(4-methylpiperidin-1-yl) ethyl) pyrrolidine-1-sulfonyl) phenol hydrochloride, SB-269970, 0.3-1 nmol/paw), but not by the 5-HT1A (N-[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]-N-2-pyridinylcyclohexanecarboxamide maleate, WAY-100635, 0.3-1 nmol/paw), 5-HT1B/1D (N-[4-methoxy-3-(4-methyl-1-piperazinyl)phenyl]-2'-methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)-1,1'-biphenyl-4-carboxamide hydrochloride hydrate, GR-127935, 0.3-1 nmol/paw), 5-HT1B (1'-methyl-5-[[2'-methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)biphenyl-4-yl]carbonyl]-2,3,6,7-tetrahydrospiro[furo[2,3-f]indole-3,4'-piperidine hydrochloride, SB-224289, 0.3-1 nmol/paw), 5-HT1D (4-(3-chlorophenyl)-α-(diphenylmethyl)-1-piperazineethanol hydrochloride, BRL-15572, 0.3-1nmol/paw) nor 5-HT5A ((N-[2-(dimethylamino)ethyl]-N-[[4'-[[(2-phenylethyl)amino]methyl][1,1'-biphenyl]-4-yl]methyl]cyclopentanepropanamide dihydrochloride, SB-699551, 1-3 nmol/paw), receptor antagonists. In marked contrast, the spinal antinociceptive effect of fluoxetine was prevented by the 5-HT1A (WAY-100635, 0.3-1 nmol/rat), 5-HT1B/1D (GR-127935, 0.3-1 nmol/rat), 5-HT1B (SB-224289, 0.3-1 nmol/rat), 5-HT1D (BRL-15572, 0.3-1 nmol/rat) and 5-HT5A (SB-699551, 1-3 nmol/rat), but not by the 5-HT2A (ketanserin, 3-10 pmol/rat), 5-HT2B (RS-127445, 3-10 pmol/rat), 5-HT2C (RS-102221, 3-10 pmol/rat), 5-HT3 (ondansetron, 3-10 nmol/rat), 5-HT4 (GR-113808, 3-100 fmol/rat), 5-HT6 (SB-258585, 3-10 pmol/rat) nor 5-HT7 (SB-269970, 0.3-1 nmol/rat), receptor antagonists. These results suggest that fluoxetine produces nociception at the periphery by activating peripheral 5-HT2A/2B/2C/3/4/6/7 receptors. In addition, intrathecal fluoxetine produces antinociception by activation of spinal 5-HT1A/1B/1D/5A receptors.
Roles of serotonin receptor subtypes for the antinociception of 5-HT in the spinal cord of rats
Eur J Pharmacol 2004 Oct 19;502(3):205-11.PMID:15476746DOI:10.1016/j.ejphar.2004.08.048.
The contribution of 5-HT (5-hydroxytryptamine) receptor subtypes to the antinociception produced by intrathecal 5-HT in the formalin test was investigated in rats. Intrathecal 5-HT suppressed both phases of behaviors produced by 5% formalin, and this was blocked by antagonists for 5-HT(1B) (3-[3-(Dimethylamino)propyl]-4-hy-droxy-N-[4-(4-pyridinyl)phenyl]benzamide dihydrochloride, GR 55562), 5-HT(2C) (N-ormethylclozapine/8-Chloro-11-(1-piperazinyl)-5H-dibenzo[b,e][1,4]diazepine, D-MC), 5-HT3 (1-Methyl-N-(8-methyl-8-azabicyclo[3.2.1]-oct-3-yl)-1H-indazole-3-carboxamide maleate, LY-278,584) and 5-HT4 receptors (4-Amino-5-chloro-2-metho-xy-benzoic acid 2-(diethylamino)ethyl ester hydrochloride, SDZ-205,557), but not the 5-HT(1D) receptor antagonist 3-[4-(4-Chlorophenyl)piperazin-1-yl]-1,1-diphenyl-2-propanol hydrochloride (BRL 15572). The 5-HT(1A) receptor antagonist N-[2-[4-(2-Methoxyphenyl)-1-piperazinyl]-N-2-pyridinyl-cyclohexanecarboxamide maleate (WAY-100635) decreased only the second phase antinociception of 5-HT. Intrathecal administration of agonists for 5-HT(1A) (3-(N,N-Dipropylaminoethyl)-1H-indole-5-carboxamide maleate, Dipropyl-5CT), 5-HT(1B) (7-Trifluoromethyl-4(4-met-hyl-1-piperazinyl)-pyrrolo[1,2-a]quinoxaline maleate, CGS-12066A), 5-HT(2C) (6-Ch-loro-2-(1-piperazinyl)pyrazine hydrochloride, MK 212), 5-HT3 (N-(3-Chlorophenyl)imidodicarbonimidic diamide hydrochloride, m-CPBG) and 5-HT4 receptors (2-[1-(4-Piperonyl)piperazinyl]benzothiazole, BZTZ) suppressed both phases of the formalin response. The results of the present study indicate that spinal 5-HT(1B,) 5-HT(2C,) 5-HT3 and 5-HT4 receptors, but not the 5-HT(1D) receptor, mediate antinociception produced by 5-HT in the formalin test. The relevance of the 5-HT(1A) receptor is less clear because of the different effects of antagonist and agonist.
Characterisation of the functional alpha-adrenoceptor subtype in the isolated female pig urethra
Eur J Pharmacol 1999 Apr 23;371(1):31-8.PMID:10355591DOI:10.1016/s0014-2999(99)00182-x.
The aim of the present study is to characterise the contraction-mediating functional alpha-adrenoceptor of the female pig urethra. Alpha-adrenoceptor reference agonists were used to contract the isolated female pig urethra. The relative intrinsic activity was noradrenaline (1.0), phenylephrine (0.91), methoxamine (0.74), (+/-)-3'-(2-amino-1-hydroxyethyl)-4'-fluoromethane-sulfonanilid e hydrochloride (NS-49) (0.68), oxymetazoline (0.60), dopamine (0.50), clonidine (0.43), midodrine (0.32), ephedrine (0.30), 5-bromo-N-(4,5-dihydro-1H-imidazol-2-yl)-6-quinoxalinamine (UK 14,304) (0.11), and phenylpropanolamine (0.11). The 21 competitive antagonists used caused parallel rightward shifts in the alpha-adrenoceptor agonist concentration-response curves, giving linear Schild-plots with slopes not significantly different from unity, suggesting that contraction was mediated by a single receptor. The antagonist pK(B) values calculated were R(-)-tamsulosin (9.68), risperidone (9.19), 2-[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]-4,4-dimethyl-1,3(2H,4H)-+ ++isoquinolinedione (AR-C 239) (9.09), 2-([2,6-dimethoxyphenoxyethyl]aminomethyl)-1,4-benzodioxane (WB-4101) (8.87), N-[3-[4-(2-methoxyphenyl)-1-piperazinyl]propyl]-3-methyl-4-oxo-2-phenyl- 4H-1-benzopyran-8-carboxamide monomethanesulfonate (Rec 15/2739/3) (8.81), 5-methylurapidil (8.59), prazosin (8.57), benoxathian (8.56), S(+)-tamsulosin (8.27), indoramin (8.11), doxazosin (7.96), alfuzosine (7.82), phentolamine (7.70), terazosin (7.52), spiperone (7.48), oxymetazoline (7.40), 8-[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]-8-azaspiro[4,5]deca ne-7,9-dione dihydrochloride (BMY 7378) (7.05), corynanthine (6.98), rauwolscine (6.40), yohimbine (6.22), and N-[2-(2-cyclopropylmethoxyphenoxy)ethyl]-5-chloro-alpha,alpha-dime thyl-1H-indole-3-ethanamine hydrochloride (RS 17053) (6.07). Correlation of subtype-selective antagonist pK(B) values was best with published values for the alpha1a/1A-adrenoceptor subtype. Therefore, the present results suggest that contraction of the female pig urethra is caused by activation of the alpha1A-adrenoceptor.
