The syntheses, characterization and in vitro metabolism of nitracaine, methoxypiperamide and mephtetramine
Drug Test Anal 2014 Jul-Aug;6(7-8):668-75.PMID:24574100DOI:10.1002/dta.1616.
Three legal highs; nitracaine (3-(diethylamino)-2,2-dimethylpropyl 4-nitrobenzoate), methoxypiperamide (MEOP, (4-methoxyphenyl)(4-methylpiperazin-1-yl)methanone) and mephtetramine (MTTA, 2-((methylamino)methyl)-3,4-dihydronaphthalen-1(2H)-one) appeared in 2013 as new psychoactive substances (NPS) on Internet websites selling 'research chemicals'. These compounds were synthesized and analyzed via our synthesize, analyze, and metabolize (SAM) protocol. Nitracaine was synthesized by the transesterification of methyl 4-nitrobenzoate with 3-(diethylamino)-2,2-dimethylpropan-1-ol. Methoxypiperamide was synthesized by the reaction of 4-methoxybenzoyl chloride with 1-methylpiperazine, and mephtetramine through the Mannich reaction of 1-tetralone with paraformaldehyde and methylamine hydrochloride. Each compound was characterized by nuclear magnetic resonance (NMR), gas chromatography with electron impact mass spectrometry (GC-EIMS), liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS), and high resolution electrospray ionization mass spectrometry (HR-ESI-MS). A sample of nitracaine was also test-purchased from an Internet vendor and its structure confirmed by GC-EIMS and LC-ESI-MS. Finally, the in vitro metabolism of the nitracaine, mephtetramine, and methoxypiperamide was investigated, using a human microsomal liver extract, in order to tentatively identify potential metabolites that may be encountered in the analysis of biological samples in clinical or toxicology labs. The use of our SAM protocol highlights the ability of academic research labs to quickly respond to and disseminate information about emerging NPS.
Role of 5-HT1A and 5-HT1B receptors in the antinociceptive effect of tramadol
Eur J Pharmacol 2005 Mar 21;511(1):21-6.PMID:15777775DOI:10.1016/j.ejphar.2005.02.006.
Tramadol, (1RS,2RS)-2-[(dimethylamine)-methyl]-1-(3-methoxyphenyl)-cyclohexanol hydrochloride, is an atypical centrally acting analgesic agent with relatively weak opioid receptor affinity and which, like some antidepressants, is able to inhibit the reuptake of serotonin (5-hydroxytryptamine, 5-HT) in the raphe nucleus. We have previously demonstrated that pindolol, a beta-adrenoceptor blocker/5-hydroxytryptamine(1A/1B) receptor antagonist, enhanced tramadol antinociception and that the selective 5-HT1A agonist 8-Hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) reduced it. These effects were related to the negative feedback control that regulates raphe region neurones. The current study examines the ability of the selective antagonist at somatodendritic 5-HT1A receptors, N-[2-[4-(2-methoxyphenyl)-1-piperazinyl] ethyl]-N-(2-pyridinyl) cyclohexane carboxamide (WAY100635, 0.8 mg/kg), the selective antagonist at terminal 5-HT1B receptors, N-[3-(2-dimethylamino) ethoxy-4-methoxyphenyl]-2'-methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)-(1,1'-biphenyl)-4-carboxamide (SB216641, 0.1-0.8 mg/kg) and the selective agonist at 5-HT1B receptors, 1,4-tDihydro-3-(1,2,3,6-tetrahydro-4-pyridinyl)-5H-pyrrolo[3,2-b] pyridin-5-one (CP93129, 0.2-0.4 mg/kg), to modify the antinociceptive effect of 4-64 mg/kg of tramadol in the hot plate test in mice. The results show that 0.8 mg/kg of WAY100635 enhanced antinociceptive effect of tramadol while neither agonism nor antagonism at the 5-HT1B receptor modifies it significantly at the doses tested. These results account for involvement of the somatodendritic 5-HT1A receptors in the analgesic effect of tramadol and support the supraspinal interaction of serotonin and the opioid system in the regulation of pain.
Stimulation of 5-HT1B receptors causes hypothermia in the guinea pig
Eur J Pharmacol 1997 Jul 23;331(2-3):169-74.PMID:9274976DOI:10.1016/s0014-2999(97)01055-8.
The selective, brain penetrant, 5-HT(1B/D) (formerly 5-HT(1D beta/alpha)) receptor agonist SKF-99101H (3-(2-dimethylaminoethyl)-4-chloro-5-propoxyindole hemifumarate) (30 mg/kg i.p.) causes a dose related fall in rectal temperature in guinea pigs which previous studies have shown to be blocked by the non-selective 5-HT(1B/D) receptor antagonist GR-127935 (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 oxalate). The present study shows that the hypothermic response to SKF-99101H is dose-dependently blocked by SB-224289G (1'-methyl-5-(2'-methyl-4'-[(5-methyl-1,2,4-oxadiazol-3-yl)bipheny l-4-yl]carbonyl)-2,3,6,7-tetrahydrospiro[furo[2,3-f]indole-3,4'-pi peridone] hemioxalate) (0.3-10.0 mg/kg p.o.) (ED50 3.62 mg/kg), which is the first compound to be described which is more than 60 fold selective for the 5-HT1B receptor over the 5-HT1D receptor. SB-216641A (N-[3-(2-dimethylamino) ethoxy-4-methoxy-phenyl] 2'-methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)-(1,1'-biphenyl)-4-car boxamide hydrochloride) (0.6-20.0 mg/kg i.p.), which is somewhat less selective (30 fold) for the 5-HT1B receptor over the 5-HT1D receptor had a similar effect (ED50 4.43 mg/kg). The brain penetrant 5-HT1D selective receptor antagonist, BRL-15572 (4-(3-chlorophenyl)-alpha-(diphenylmethyl)-1-piperazineethanol+ ++ dihydrochloride) (0.3-100.0 mg/kg i.p.) was inactive. When administered alone neither BRL-15572 (0.1-10 mg/kg i.p.) nor SB-224289G (2.2-22 mg/kg p.o.) had an effect on body temperature. These data demonstrate that 5-HT1B (formerly 5-HT(1D beta)) and not 5-HT1D (formerly 5-HT(1D alpha)) receptors mediate the hypothermic response to SKF-99101H (30 mg/kg i.p.) in guinea pigs. The compounds described are useful pharmacological tools for distinguishing responses to 5-HT1B and 5-HT1D receptors.
Role of 5-HT1B/D receptors in canine gastric accommodation: effect of sumatriptan and 5-HT1B/D receptor antagonists
Am J Physiol Gastrointest Liver Physiol 2003 Jul;285(1):G96-104.PMID:12646419DOI:10.1152/ajpgi.00280.2002.
The 5-HT1B/D receptor agonist sumatriptan has been proposed to treat dyspeptic symptoms, because it facilitates gastric accommodation. It is unknown whether stimulation of 5-HT1B/D receptors is involved. Thus, in four conscious dogs, we compared the effects of sumatriptan alone or combined with 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 hydrocloride (GR-127935), N-[3-[3 (dimethylamino)-ethoxy]-4-methoxyphenyl]-2'-[methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)]-[1,1-biphenyl]-4-carboxamide hydrocloride (SB-216641 hydrochloride), or 3-[4-(4-chloro-phenyl)piperazin-1-yl]-1,1-diphenyl-2-propanol hydrochloride (BRL-15572 hydrochloride) (respectively, nonselective 5-HT1B/D, selective 5-HT1B, and selective 5-HT1D receptor antagonists) on gastric accommodation to isobaric distensions performed with a barostat. An exponential and a linear model were used to fit the pressure-volume relationship. An exponential equation fitted the data better than a linear equation. Sumatriptan (800 nmol/kg iv) induced an immediate gastric relaxation (Deltavolume: 112 +/- 44 ml, P < 0.05). After sumatriptan, the pressure-volume curve was shifted toward significantly higher volumes. This effect was fully reversed by GR-127935 or SB-216641 but not by BRL-15572. In conclusion, 5-HT1B receptors seem to play an important role in modulating gastric accommodation to a distending stimulus. An exponential model for pressure-volume curves fits well with the concept of gastric adaptive relaxation.
Differential effects of 5-HT agonists and antagonists on the repeated acquisition and performance of response sequences in monkeys
Behav Pharmacol 2000 Nov;11(7-8):535-53.PMID:11198126DOI:10.1097/00008877-200011000-00002.
As a means of characterizing the role of 5-HT1A and 5-HT2A receptors in learning, 5-hydroxytryptamine (5-HT) agonists and antagonists with selective affinities for each receptor subtype (i.e. 8-hydroxy-dipropylaminotetralin (8-OH-DPAT), (-)-4-(dipropylamino)-1,3,4,5-tetrahydrobenz-(c,d,)indole-6-carboxamide (LY228729), (+/-)-1-(4-iodo-2,5-dimeth-oxyphenyl)-2-aminopropane hydrochloride (DOI), 4-iodo-N-[2- [4-(methoxyphenyl)-1-piperazinyl] ethyl]-N-2-pyridinyl-benzamide hydrochloride (p-MPPI), N-[2- [4- (2-methoxyphenyl)-1-piperazinyl] ethyl] -N-2-pyridinyl-cyclohexanecarboxamide maleate (WAY-100635), 1-(2-methoxyphenyl)-4-[4-(2-phthalimido)butyllpiperazine hydrobromide (NAN-190) and ritanserin) were administered to monkeys responding under a multiple schedule of repeated acquisition and performance. In addition, a selective 5-HT1A receptor agonist (8-OH-DPAT) was administered in combination with a 5-HT2A receptor antagonist (ritanserin) to examine any potential interactions between the two 5-HT receptor subtypes. When administered alone, 8-OH-DPAT (0.1-3.2mg/kg), LY228729 (0.32-3.2 mg/kg) and DOI (0.018-3.2 mg/kg) dose-dependently decreased overall response rate in both schedule components, and generally increased the percentage of errors in the acquisition components at doses lower than those that increased the percentage of errors in the performance components. At the doses of each drug tested (i.e. 0.1 or 0.32 mg/kg), both p-MPPI and WAY-100635 antagonized the disruptive effects of 8-OH-DPAT, by shifting the dose-effect curves for overall response rate and the percentage of errors to the right. In contrast, ritanserin (0.32 or 1mg/kg) had little or no effect on the disruptions produced by 8-OH-DPAT, but it effectively antagonized the rate-decreasing and error-increasing effects produced by the 5-HT2A agonist DOI. Administration of the 5-HT1A antagonists WAY-100635 and NAN-190 alone produced dose-dependent rate-decreasing effects, but the effects on accuracy of responding in the acquisition components differed from those of the 5-HT1A agonists (8-OH-DPAT and LY228729), in that they did not produce an increase in the percentage of errors. Together, these results suggest that 5-HT is capable of disrupting learning in monkeys through actions at both the 5-HT1A and 5-HT2A receptors, and that 5-HT2A receptor antagonism does not unilaterally modify the effects produced by 5-HTA1A receptor activation.
