Development of novel chiral capillary electrophoresis methods for the serotonin receptor (5-HT2A) antagonist MDL 100,907 (volinanserin) and for its key intermediate compound.[Pubmed:24216279]

J Pharm Biomed Anal. 2014 Jan;88:579-83.

Enantioselective capillary electrophoretic methods were elaborated for the determination of the enantiomeric purity of (R)-MDL 100,907 and its preparatively resolved key intermediate compound during the synthesis route. The pKa values of the intermediate compound and the end product determined by CE were 10.5+/-0.1 and 9.0+/-0.1, respectively. The enantiopurity of the intermediate compound can be monitored in fully protonated state by applying 15mM sulfobutylether-beta-cyclodextrin at pH 5 when the peak belonging to the impurity migrates before the main component. The fact that the consecutive steps of the synthesis do not affect the enantiomeric purity was verified by the other, newly developed CE method. The enantiomers of rac-MDL 100,907 were resolved by 15mM carboxymethyl-gamma-cyclodextrin at pH 3. The applicability (selectivity, LOD, LOQ, repeatability, precision and accuracy) of the methods was studied as well.

The 5-HT(2A) receptor and serotonin transporter in Asperger's disorder: A PET study with [(1)(1)C]MDL 100907 and [(1)(1)C]DASB.[Pubmed:22079057]

Psychiatry Res. 2011 Dec 30;194(3):230-234.

Evidence from biochemical, imaging, and treatment studies suggest abnormalities of the serotonin system in autism spectrum disorders, in particular in frontolimbic areas of the brain. We used the radiotracers [(11)C]MDL 100907 and [(11)C]DASB to characterize the 5-HT(2A) receptor and serotonin transporter in Asperger's Disorder. Seventeen individuals with Asperger's Disorder (age=34.3 +/- 11.1 years) and 17 healthy controls (age=33.0 +/- 9.6 years) were scanned with [(11)C]MDL 100907. Of the 17 patients, eight (age=29.7 +/- 7.0 years) were also scanned with [(1)(1)C]DASB, as were eight healthy controls (age=28.7 +/- 7.0 years). Patients with Asperger's Disorder and healthy control subjects were matched for age, gender, and ethnicity, and all had normal intelligence. Metabolite-corrected arterial plasma inputs were collected and data analyzed by two-tissue compartment modeling. The primary outcome measure was regional binding potential BP(ND). Neither regional [(1)(1)C]MDL 100907 BP(ND) nor [(1)(1)C]DASB BP(ND) was statistically different between the Asperger's and healthy subjects. This study failed to find significant alterations in binding parameters of 5-HT(2A) receptors and serotonin transporters in adult subjects with Asperger's disorder.

Analysis of 5-HT(2A) receptor binding with [(11)C]MDL 100907 in rats: optimization of kinetic modeling.[Pubmed:23660769]

Mol Imaging Biol. 2013 Dec;15(6):730-8.

PURPOSE: Preclinical positron emission tomography studies are important to follow disease progression and develop new pharmacological agents. We investigated whether kinetic modeling of 5-HT2A tracer [(11)C]MDL 100907 is possible in rats. PROCEDURES AND RESULTS: Kinetic modeling with either metabolite-corrected plasma curve or with the cerebellum as a reference tissue resulted in a good correlation of nondisplaceable binding potential (BPND) calculated from a two-tissue compartment model (2TCM) or different reference tissue models. Injecting the tracer by a slower bolus decreases the variation in 2TCM outcome parameters and results in a good correlation between k3/k4 and the other models. Application of 0.2 mg/kg cold MDL 100907 resulted in almost complete occupancy of 5-HT2A receptors. CONCLUSIONS: A reference tissue model can be used for [(11)C]MDL kinetic modeling in rats, which is preferable in pharmacological or longitudinal studies.

Sustained recreational use of ecstasy is associated with altered pre and postsynaptic markers of serotonin transmission in neocortical areas: a PET study with [(1)(1)C]DASB and [(1)(1)C]MDL 100907.[Pubmed:22353758]

Neuropsychopharmacology. 2012 May;37(6):1465-73.

3,4-Methylenedioxymethamphetamine (MDMA), the main psychoactive component of the recreational drug ecstasy, is a potent serotonin (5-HT) releaser. In animals, MDMA induces 5-HT depletion and toxicity in 5-HT neurons. The aim of this study was to investigate both presynaptic (5-HT transporter, SERT) and postsynaptic (5-HT(2A) receptor) markers of 5-HT transmission in recently abstinent chronic MDMA users compared with matched healthy controls. We hypothesized that MDMA use is associated with lower SERT density and concomitant upregulation of 5-HT(2A) receptors. Positron emission tomography studies using the SERT ligand [(1)(1)C]DASB and the 5-HT(2A) receptor ligand [(1)(1)C]MDL 100907 were evaluated in 13 current and recently detoxified MDMA users and 13 matched healthy controls. MDMA users reported a mean duration of ecstasy use of 8 years, regular exposure, and at least 2 weeks of abstinence before the scans. SERT and 5-HT(2A) receptor availability (binding potential, BP(ND)) were analyzed with a two-tissue compartment model with arterial input function. Current recreational MDMA use was significantly associated with lower SERT BP(ND) and higher 5-HT(2A) receptor BP(ND) in cortical, but not subcortical regions. Decreased SERT BP(ND) was regionally associated with upregulated 5-HT(2A) receptor BP(ND). In light of the animal literature, the most parsimonious interpretation is that repeated exposure to MDMA in humans, even in moderate amounts, leads to damage in 5-HT neuron terminals innervating the cortex. Alterations in mood, cognition, and impulse control associated with these changes might contribute to sustain MDMA use. The reversibility of these changes upon abstinence remains to be firmly established.

The 5-hydroxytryptamine2A receptor antagonist R-(+)-alpha-(2,3-dimethoxyphenyl)-1-[2-(4-fluorophenyl)ethyl-4-piperidinemethanol (M100907) attenuates impulsivity after both drug-induced disruption (dizocilpine) and enhancement (antidepressant drugs) of differential-reinforcement-of-low-rate 72-s behavior in the rat.[Pubmed:18772320]

J Pharmacol Exp Ther. 2008 Dec;327(3):891-7.

Previous work has suggested that N-methyl-d-aspartate (NMDA) receptor antagonism and 5-hydroxytryptamine (5-HT)(2A) receptor blockade may enhance and attenuate, respectively, certain types of impulsivity mediated by corticothalamostriatal circuits. More specifically, past demonstrations of synergistic "antidepressant-like" effects of a 5-HT(2A) receptor antagonist and fluoxetine on differential-reinforcement-of-low-rate (DRL) 72-s schedule of operant reinforcement may speak to the role of 5-HT(2A) receptor blockade with respect to response inhibition as an important prefrontal cortical executive function relating to motor impulsivity. To examine the dynamic range over which 5-HT(2A) receptor blockade may exert effects on impulsivity, [R-(+)-alpha-(2,3-dimethoxyphenyl)-1-[2-(4-fluorophenyl)ethyl-4-piperidinemethano l] (M100907) was examined both alone and in combination with the psychotomimetic NMDA receptor antagonist dizocilpine [e.g., (-)-5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine maleate; MK-801] and two different antidepressants, the tricyclic antidepressant desmethylimipramine (DMI) and the monoamine oxidase inhibitor tranylcypromine in rats performing under a DRL 72-s schedule. MK-801 increased the response rate, decreased the number of reinforcers obtained, and exerted a leftward shift in the inter-response time (IRT) distribution as expected. A dose of M100907 that exerted minimal effect on DRL behavior by itself attenuated the psychotomimetic effects of MK-801. Extending previous M100907-fluoxetine observations, addition of a minimally active dose of M100907 to low doses of DMI and tranylcypromine enhanced the antidepressant-like effect of the antidepressants. Therefore, it may be that a tonic excitation of 5-HT(2A) receptors modulates impulsivity and function of corticothalamostriatal circuits over an extensive dynamic range.

Preclinical characterization of the potential of the putative atypical antipsychotic MDL 100,907 as a potent 5-HT2A antagonist with a favorable CNS safety profile.[Pubmed:8627580]

J Pharmacol Exp Ther. 1996 May;277(2):968-81.

In preclinical studies, [R-(+)-alpha-(2,3-dimethoxyphenyl)-1-[2-(4-fluorophenyl)ethyl]-4- piperidinemethanol] [formula: see text] (MDL 100,907), a putative atypical antipsychotic, was characterized in vitro as a potent and selective ligand for the serotonin2A (5-HT2A) receptor and was evaluated in vitro and in vivo as a potent 5-HT2A receptor antagonist. Furthermore, MDL 100,907's potential CNS safety profile and selectivity as a potential antipsychotic agent were evaluated and compared with benchmark compounds. MDL 100,907 demonstrated low nanomolar or subnanomolar binding in vitro at the 5-HT2A receptor and showed a > 100-fold separation from all other receptors measured. MDL 100,907 had subnanomolar potency as a 5-HT2A antagonist in vitro in reversing 5-HT-stimulated inositol phosphate accumulation in NIH 3T3 cells transfected with the rat 5-HT2A receptor. In vivo, MDL 100,907 potently inhibited 5-methoxy-N, N-dimethyltryptamine-induced head twitches in mice or 5-hydroxytryptophan-induced head twitches in rats. In vivo functional tests in mice revealed a > 500-fold separation between doses that produced 5-HT2A antagonism and doses that produced alpha 1-adrenergic or striatal D2 antagonism. Using inhibition of D-amphetamine-stimulated locomotion in mice as a measure of potential antipsychotic efficacy, MDL 100,907 showed a superior CNS safety index relative to the reference compounds, haloperidol, clozapine, risperidone, ritanserin, and amperozide, in each of five tests for side effect potential, including measures of ataxia, general depressant effects, alpha 1-adrenergic antagonism, striatal D2 receptor antagonism, and muscle relaxation. MDL 100,907 did not antagonize apomorphine-induced stereotypes in rats, suggesting that it potentially lacks extrapyramidal side effect liability. MDL 100,907 showed selectivity as a potential antipsychotic in that it lacked consistent activity in selected rodent models of anticonvulsant, antidepressant, analgesic, or anxiolytic activity. In summary, these preclinical data indicate that MDL 100,907 is a potent and selective ligand at the 5-HT2A receptor. MDL 100,907's potent 5-HT2A antagonist activity might account for its activity in preclinical models of antipsychotic potential. Ongoing clinical evaluation with MDL 100,907 will test the hypothesis that 5-HT2A receptor antagonism is sufficient for antipsychotic activity in humans.

Characterization of the 5-HT2 receptor antagonist MDL 100907 as a putative atypical antipsychotic: behavioral, electrophysiological and neurochemical studies.[Pubmed:8102646]

J Pharmacol Exp Ther. 1993 Aug;266(2):684-91.

Progress toward understanding the role of the 5-hydroxytryptamine (5-HT)2 receptor in the therapy for schizophrenia has been hampered by the lack of highly selective antagonists. We now report on the effects of MDL 100,907 [R(+)-alpha-(2,3-dimethoxyphenyl)-1- [2-(4-fluorophenylethyl)]-4-piperidine-methanol], a highly selective and potent 5-HT2 receptor antagonist, in behavioral, electrophysiological and neurochemical models of antipsychotic activity and extrapyramidal side-effect liability. In mice, MDL 100,907 blocked amphetamine-stimulated locomotion at doses that did not significantly affect apomorphine-stimulated climbing behavior. Neither MDL 100,907 nor clozapine reduced apomorphine-induced stereotypies or produced catalepsy in rats. MDL 100,907 blocked the slowing of ventral tegmental area (A10) dopaminergic neurons by amphetamine but, like clozapine, produced only small increases in the number of active substantia nigra zona compacta (A9) and A10 dopamine neurons after acute administration. When administered chronically, MDL 100,907 and clozapine selectively reduced the number of spontaneously active A10 neurons, whereas haloperidol reduced activity in both the A9 and A10 regions. Consistent with their acute effect on A9 and A10 activity, neither MDL 100,907 nor clozapine increased dopamine metabolism in the striatum or nucleus accumbens, whereas acute haloperidol accelerated dopamine turnover in both regions. The administration of the dopamine uptake blocker amfonelic acid with haloperidol produced a massive increase in DA metabolism characteristic of typical antipsychotics. In contrast, MDL 100,907 and clozapine were without effect on dopamine turnover when given in the presence of amfonelic acid. These data indicate that MDL 100,907 has a clozapine-like profile of potential antipsychotic activity with low extrapyramidal sid-effect liability.(ABSTRACT TRUNCATED AT 250 WORDS)
