Texto completo da fonteIn the first part of this thesis, we obtained a trans-indoloquinolizidine-peptide hybrid (IP28) obtained by a combinatorial approach, behaved as an orthosteric ligand of all dopamine D2- like receptors (D2, D3, and D4) and dopamine D5 receptors, but as a negative allosteric modulator of agonist and antagonist binding to striatal dopamine D1 receptors. Indoloquinolizidine-peptide 28 induced a concentration-dependent hyperbolic increase in the antagonist apparent equilibrium dissociation constant values and altered the dissociation kinetics of dopamine D1 receptor antagonists. In the second part of this thesis, we show that whereas the most frequent 4-repeat (D4.4) and the 2-repeat (D4.2) variants form functional heteromers with the short isoform of the dopamine D2 receptor (D2S), the 7-repeat risk allele (D4.7) does not. D2 receptor activation in the D2S–D4 receptor heteromer potentiates D4 receptor- mediated MAPK signaling in transfected cells and in the striatum, which did not occur in cells expressing D4.7 or in the striatum of knockin mutant mice carrying the 7 repeats of the human D4.7 in the third intracellular loop of the D4 receptor. Using the same receptor, le dopamine D4R, in the third part of this thesis, we describe that the production of both melatonin and serotonin by the pineal gland is regulated by a circadian-related heteromerization of adrenergic and dopamine D4 receptors. Through α1B-D4 and β1-D4 receptor heteromers dopamine inhibits adrenergic receptor signaling and blocks the synthesis of melatonin induced by adrenergic receptor ligands. And this inhibition was not observed at hours of the day when D4 was not expressed. Finally, in the last part of this thesis, we made the systematic derivatization of two ergopeptides with different peptide-based spacers and we realized their evaluation by radioligand binding assays. Selected spacer-containing ergopeptides with minimal biological alteration and a proper anchoring point were further derivatized with a biotin reporter. Detailed characterization studies identified 13 as a biotin ergopeptide maintaining high affinity and agonist behavior at dopamine receptors, being a useful tool for the study of heteromers involving D1R, D2R, or D3R.

Texto completo da fonteNo presente trabalho, foi avaliado a interaÃÃo entre os sistemas dopaminÃrgico e colinÃrgico atravÃs do estudo dos efeitos comportamentais (campo aberto e catalepsia) e neuroquÃmicos (densidade de receptores dopaminÃrgicos (D1 e D2-sÃmile) e muscarÃnicos (M1+M2-sÃmile) em corpo estriado de rato. As seguintes drogas foram utilizadas: mazindol (agonista dopaminÃrgico indireto), apomorfina (agonista dopaminÃrgico D1-sÃmile e D2-sÃmile), pimozida (antagonista dopaminÃrgico D2-sÃmile), SCH 23390 (antagonista dopaminÃrgico D1-sÃmile), pilocarpina (agonista muscarÃnico M1-sÃmile), carbacol (agonista muscarÃnico M2-sÃmile), pirenzepina (antagonista muscarÃnico M1-sÃmile), atropina (antagonista muscarÃnico M1 e M2 nÃo seletivo), clozapina (neurolÃptico atÃpico). Os resultados mostraram que a pimozida e o carbacol, sozinhos ou associados, causaram um aumento da resposta catalÃptica e uma diminuiÃÃo da atividade locomotora. O mazindol tambÃm aumentou a atividade locomotora. Carbacol, nas menores doses, e o mazindol aumentaram a densidade de receptores D1-sÃmile. A pimozida e a atropina, isoladamente, aumentaram a densidade de receptores D1-sÃmile no corpo estriado enquanto que a atropina causou uma diminuiÃÃo dos receptores D2-sÃmile e uma upregulation dos receptores muscarÃnicos. O mazindol aumentou o binding de 3H-NMS no corpo estriado. O presente trabalho sugere, de maneira geral, que existe uma relaÃÃo entre os receptores muscarÃnicos M1 e M2 com os receptores dopaminÃrgicos D1 e D2, sendo que esta relaÃÃo pode ocorrer de maneira positiva ou negativa, dependendo da seletividade e da dose das drogas utilizadas
In the study, the interaction between the dopaminergic and cholinergic systems through the study of behavioral (open field and catalepsy) and neurochemical (density of dopaminergic receptor (D1 and D2-like) and muscarinic (M1+M2-like)) effect in striatum rat was evaluated. The following drugs were used: mazindol (indirect dopaminergic agonist), apomorphine (D1-like and D2-like dopaminergic agonist), pilocarpine (M1-like muscarnic aginist), carbachol (M-2like agonist muscarinc), pirenzepine (M1-like antagonist muscarinic), atropine (non-selective M1 and M2 antagonist muscarinic), clozapina(non-typical neuroleptic). The results showed that the pimozida and carbachol, alone or associated, caused increase in the cataleptic response and reduction in the motor activity. The mazindol also increased the motor activity. In small dosage, the carbachol and mazindol increased the density of D1-like receptors. Isolated, the pimozida and atropine increased the density of the D1-like receptors in striatum whereas the atropine caused a reduction of D2-like receptors and upregulation of muscarinic receptors. This work suggests a relationship, between muscarinc receptors M1 and M2 and dopaminergic receptors D1 and D2, and that this relationship can occur in a positive and negative manner, depending on the selectivity and the dose of the used drug

Texto completo da fonteThe subject of this work is focused in the utilization of a bottom-up approach to develop an Au nanostructured electrodeposits on the glassy carbon surface by a voltammetric procedure. These Au nanostructures have been characterized either by microscopic and voltammetric techniques. The critical dimensions of nanostructures has been evaluated by a Gausean normal data distribution curve and presented, as results a mean height of 35 nm and a mean diameter of 150 nm. The Au nanostructures were further modified by the deposition of a cystamine (thiol) self-assembled monolayer, yielding a suitable substrate for enzyme immobilization, as a possible future application. The electrochemical behaviour of dopamine and ascorbic acid on gold, Glassy Carbon and nanostructures was studied aiming to characterize the modified electrode. The 300 mV shift in the oxidation peak potential for ascorbic acid on gold in relation to Glassy Carbon allows to calculate the nanostructure coverage factor by the peak current inhibition as 43%. Finally, dopamine was employed to detect the self assembled monolayer formation on the Au nanostructure through its voltammetric behaviour. The variation in the oxidation potential for DA on gold and self assembled monolayer was used as an indicator for such modification.

A dopamina e um composto endogeno amplamente utilizado em terapia intensiva. Possui um amplo espectro de acoes, tanto sobre o sistema cardiovascular como urinario. Aumento da taxa de filtracao glomerular, do fluxo sanguineo renal e excrecao fracionada de sodio e fosforo sao efeitos renais esperados em individuos normais, porem sao pouco explorados na medicina veterinaria. Com o proposito de testar a hipotese que a dopamina e capaz de aumentar a excrecao fracionada de fosforo em caes nefropatas, este estudo foi conduzido. Diferentes doses de dopamina foram administradas em caes nefropatas. Avaliacoes laboratoriais foram realizadas durante e apos os tratamentos. O clearance de creatinina e a excrecao fracionada de fosforo apresentaram aumento dose-dependente nos caes sadios. Em caes nefropatas, a dose de 1 Êg/kg/min aumentou discretamente a TFG, alem de aumentar o volume urinario e excrecao de fosfato, sem modificar a U-P/C e pressao arterial sistemica, enquanto a dose de 3 Êg/kg/min nao aumentou os beneficios e, ainda, promoveu aumento da excrecao urinaria de proteinas.
Dopamine is a endogenous compound largely used in critical care. It has a large spectrum of actions on cardiovascular and urinary systems. Increases in glomerular filtration rate, renal blood flow and frational excretion of sodium and phosphate are renal effects expected in healthy patient, but there are few reports in veterinary medicine. In order to test the hypothesis that dopamine can increase frational excretion of phosphate in nephropathy dogs this study was conducted. Different dopamine doses were administered in nephropathy dogs. Laboratory evaluations were done during and after treatments. Creatinin clearance and frational excretion of phosphate increases dose-dependent form in healthy dogs. In the nephropathy dogs, the dose of 1ìg/kg/min increased the glomerular filtration rate, urinary volume and phosphate excretion, without modified U-P/C and systemic arterial blood pressure, while the dose of 3ug/kg/min don t increased the benefits and promoted a increase in the urinary excretion of proteins.

Los cambios en la neurotransmisión de dopamina contribuyen a los trastornos neurológicos y psiquiátricos. Hallazgos recientes de nuestro grupo (Ma et al., 2015; González-Sepúlveda et al., presentado) describieron los fuertes efectos de varias clases de medicamentos dopaminérgicos en la síntesis de dopamina, incluida L-DOPA (utilizada en Parkinson), tetrabenazina (Huntington) y aripiprazol (esquizofrenia). En este estudio, confirmamos y ampliamos esos hallazgos y comparamos los efectos de los antipsicóticos agonistas parciales D2R cariprazina y brexpiprazol, las psicoestimulantes anfetamina y metilfenidato varios otros compuestos selectivos y experimentales. El estriado cerebral de rata fue troceado e incubado ex-vivo en presencia o ausencia de estos fármacos a diferentes concentraciones. Espontáneamente, la dopamina y la serotonina se acumularon con el tiempo alcanzando niveles de almacenamiento casi máximos. Este enfoque experimental nos permitió evaluar su dinámica de síntesis y almacenamiento bajo la influencia de los agentes farmacológicos elegidos. Nuestros resultados podrían ser útiles para comprender los mecanismos de acción de los antipsicóticos, y podrían facilitar la investigación futura con modelos animales y ensayos clínicos utilizando nuevos agentes dopaminérgicos.
Presynaptic dopaminergic regulation is important to maintain a homeostatic balance of dopamine stored levels and release. Changes in dopamine neurotransmission contribute to neurological and psychiatric disorders. Recent findings from our group (Ma et al., 2015; González-Sepúlveda et al.,-submitted) describe strong effects of several classes of dopaminergic drugs on dopamine synthesis, including L-DOPA (used in Parkinson), tetrabenazine (Huntington) and aripiprazole (schizophrenia). In this study, I confirm and extend those findings and compare the effects of D2R partial agonist antipsychotics cariprazine and brexpiprazole, the psychostimulants amphetamine and methylphenidate, and several other selective and experimental compounds. Rat brain striatum was minced and incubated ex-vivo in the presence or absence of these drugs at different concentrations. Spontaneously, dopamine and serotonin accumulated over time reaching near-maximal storage levels. This experimental approach allowed me to evaluate their synthesis and storage dynamics under the influence of chosen pharmacological agents. My results could be useful to understand the mechanisms of action of antipsychotics, and they could facilitate further research with animal models and clinical trials using new dopaminergic agents.

Resumo: Muitas doenças neurodegenerativas são associadas com disfunções de neurotransmissores, em particular catecolaminas, no cérebro. Numerosas pesquisas têm indicado que íons metálicos podem induzir estresse oxidativo - dependente da neurodegeneração de dopamina e são responsáveis pelo aparecimento de doenças neurodegenerativas. Em estudos prévios foi verificado que alguns carboxilatos diminuem a velocidade de oxidação de catecolaminas e inibem a passivação de eletrodos sólidos durante a análise voltamétrica destes compostos fenólicos. Este trabalho teve por objetivo estudar a influência de carboxilatos (EDTA, NTA, EGTA, DTPA, acetato, citrato e oxalato) e íons metálicos (Ce(IV), Fe(III) e Hg(II)) durante a oxidação de neurotransmissores (dopamina, serotonina, epinefrina, norepinefrina e L-dopa) no intuito de estabelecer mecanismos de reações que possam contribuir no esclarecimento do papel destes compostos no processo de degeneração dos neurotransmissores, assim como compreender como os carboxilatos inibem o envenenamento do eletrodo durante a varredura de potencial. Para eses propósitos foram empregadas as técnicas de espectrofotometria, voltametria e espectroeletroquímica. A cela espectroeletroquímica de camada delgada desenvolvida incorporou um sistema de três eletrodos, sendo o eletrodo de trabalho uma minigrade de Pt. O sistema foi caracterizado usando o-tolidina e K4[Fe(CN)6]/ K3[Fe(CN)6] e permitiu o monitoramento das reações in situ. Os resultados obtidos mostraram que os carboxilatos desprotonados interagem com os produtos intermediários formados durante a oxidação das catecolaminas por meio de ligações de hidrogênio, sendo estas interações dependentes do pH do meio, estruturas do carboxilato e do próprio neurotransmissor. Foi proposto um mecanismo eletroquímico para a oxidação de aminas biogênicas na presença de carboxilatos no eletrodo de platina. A estabilização dos produtos intermediários formados inibe a formação de compostos poliméricos que são responsáveis pelo envenenamento do eletrodo. Do mesmo modo, os carboxilatos retardam ou inibem a oxidação química de algumas aminas biogênicas por íons metálicos
Abstract: Several neurological disorders are associated with improper catechoalmine regulation in the brain. Numerous researches have indicated that metallic ions can induce oxidative stress-dependent neurodegeneration of dopamine, and are responsible for the induction of neurodegenerative diseases. In previous work was verified that some carboxylates diminishes the oxidation rate of catecholamines and inhibit the well known solid state electrode passivation during voltammetric analysis of these phenolic compounds. The aim of this work was to study the influence of carboxylates (EDTA, NTA, EGTA, DTPA, acetate, oxalate and citrate) and metallic ions (Ce(IV), Fe(III) and Hg(II)) during the oxidation of neurotransmitters (dopamine, serotonin, epinephrine, norepinephrine and L-dopa) in order to establish putative reaction mechanism which could contribute to understand the role of these compounds in neurodegenerative processes, as well as comprehend how the carboxylates inhibit the electrode fouling during potential scan. For these purposes, the studies were carried out using spectrophotometric, voltammetric and spectroelectrochemical techniques. The spectroelectrochemical thin layer cell developed incorporated a three electrode system, using a Pt- minigrade as working electrode. The system was characterized employing o-tolidine and K4[Fe(CN)6]/ K3[Fe(CN)6] and allowed monitoring the electrode reactions in situ. The results obtained showed that the deprotonated carboxylates interacts with the intermediates formed at the electrochemical oxidation of catecholamines by hydrogen bonds. These interactions are dependent on the pH of the medium, as well as on the chemical structures of the carboxylates and neurotransmitters itself. An electrochemical mechanism for the oxidation of biogenic amines in the presence of carboxylates at the platinum electrode is proposed. The stabilization of the intermediates formed inhibits the formation of polymeric compounds that are responsible for the electrode fouling. In the same manner, the carbolxylates retards or inhibit the chemical oxidation of some biogenic amines by metallic ions by the same reaction pathway

Texto completo da fonteDRD4 is one of the most variable genes in the human genome. Its third exon presents a VNTR polymorphism of 48 bp. Furthermore, SNPs were observed into repeats, composing at least 74 different haplotypes variants until now. The seven repeat (7R) allele is the most frequent in South America Amerindian populations and may be under positive selection. DRD4 is a candidate gene for many association studies between psychiatric disorders and genetics. Then, it is important to study the variability of this locus in Amerindian populations because they represent one of three parental groups of admixed populations in South America. In this study, the genetic variability concerning this locus was studied in 172 subjects from Kaingang and Guarani populations of Brazilian Center-SE. Furthermore, all 7R homozygous individuals were sequenced. The results were integrated with those published, aiming to re-evaluate DRD4 variability into South America. 18 populations and 568 individuals were integrated to the analysis. The observed frequency in Kaingang and Guarani populations were intermediate between those reported in the Amazon region and in Argentina. The sequence data revealed that Kaingang and Guarani-Kaiowá were monomorphic showing only the most frequent worldwide haplotype while the Guarani-Ñandeva population was polymorphic for this locus. The DA genetic distance indicates that the predominantly hunter-gatherer populations were tightly clustered whereas the predominantly agriculturalist populations were more scattered. Fisher Exact Test revealed an excess of the 7R allele in predominantly hunter-gatherer populations when compared with agriculturalists and a correlation between latitude and 7R frequency was observed, that indicates that the high frequencies of 7R are in North, where most of hunter-gatherer populations are located. Our results suggest indirectly that positive selection could be acting on the DRD4 gene. It is possible that the DRD4 gene have influenced life habits of South American native populations. 7R could be adaptative in populations with more explorative behavior and with predominantly hunter and gatherer subsistence. Further studies considering larger numbers of hunter-gatherer populations in the south would provide a better interpretation of the genetic variability of the Amerindian populations and clarify the patterns of DRD4 evolution in South America.

Texto completo da fonteRomantic love involves biochemical processes in which substances such as neurotransmitters, neuromodulators and hormones interact with other nerve cells or organs. When being in love, dopamine levels increases, generating attention, desire and motivation in everything related to the beloved person. Serotonin, however, is present in low levels in this state. When the body does not supply the necessary amount of dopamine, oxytocin is released. Oxytocin is vital in long term relationships. Understanding the mechanism of oxytocin in humans is crucial not only for academic knowledge of the chemistry of love but also because it provides new lights for the treatment of some psychological disorders.
