RNA-editing of the 5-HT(2C) receptor alters agonist-receptor-effector coupling specificity. (1/16)

1. The serotonin(2C) (5-HT(2C)) receptor couples to both phospholipase C (PLC)-inositol phosphate (IP) and phospholipase A(2) (PLA(2))-arachidonic acid (AA) signalling cascades. Agonists can differentially activate these effectors (i.e. agonist-directed trafficking of receptor stimulus) perhaps due to agonist-specific receptor conformations which differentially couple to/activate transducer molecules (e.g. G proteins). Since editing of RNA transcripts of the human 5-HT(2C) receptor leads to substitution of amino acids at positions 156, 158 and 160 of the putative second intracellular loop, a region important for G protein coupling, we examined the capacity of agonists to activate both the PLC-IP and PLA(2)-AA pathways in CHO cells stably expressing two major, fully RNA-edited isoforms (5-HT(2C-VSV), 5-HT(2C-VGV)) of the h5-HT(2C) receptor. 2. 5-HT increased AA release and IP accumulation in both 5-HT(2C-VSV) and 5-HT(2C-VGV) expressing cells. As expected, the potency of 5-HT for both RNA-edited isoforms for both responses was 10 fold lower relative to that of the non-edited receptor (5-HT(2C-INI)) when receptors were expressed at similar levels. 3. Consistent with our previous report, the efficacy order of two 5-HT receptor agonists (TFMPP and bufotenin) was reversed for AA release and IP accumulation at the non-edited receptor thus demonstrating agonist trafficking of receptor stimulus. However, with the RNA-edited receptor isoforms there was no difference in the relative efficacies of TFMPP or bufotenin for AA release and IP accumulation suggesting that the capacity for 5-HT(2C) agonists to traffic receptor stimulus is lost as a result of RNA editing. 4. These results suggest an important role for the second intracellular loop in transmitting agonist-specific information to signalling molecules.  (+info)

Molecular basis of partial agonism: orientation of indoleamine ligands in the binding pocket of the human serotonin 5-HT2A receptor determines relative efficacy. (2/16)

Based on experiment and computational simulation, we present a structural explanation for the differing efficacies of indole agonists at the human serotonin 5-HT2A receptor (5HT2AR). We find that serotonin [5-hydroxytryptamine (5-HT)] forms hydrogen-bonds with Ser3.36 in helix 3 and Ser5.46 in helix 5. Disruption of these hydrogen bonds by methyl-substitution of the cationic primary amine or of the backbone N1-amine, respectively, leads to a reduction in agonist efficacy. Computational simulation predicts that mutation of Ser3.36 to Ala should allow a similar interaction with helix 3 both for agonists that have unmodified cationic amine side chains and for those with substituted amines. Experimentally, this mutation was found to largely eliminate the differences in efficacy caused by cationic amine substitution for a series of indole congeners. Similarly, substitution of the N1-amine, which interacts with Ser5.46, reduced efficacy more markedly at the wild-type (WT) than at the Ser5.46Ala mutant receptor. Computational modeling of binding pocket interactions of ligands with WT and mutant receptor constructs demonstrate how the Ser3.36 and Ser5.46 interactions serve to modify the agonist's favored position in the binding pocket. A striking correlation was found between differences in the position assumed by the indole ring and differences in agonist activity. These data support the hypothesis that the position of the agonist interacting with the receptor is influenced by specific interactions in helices 3 and 5 and determines the degree of receptor activation by agonist through a mechanism that is likely to be shared by other G-protein coupled receptors in this class.  (+info)

Psychedelic 5-methoxy-N,N-dimethyltryptamine: metabolism, pharmacokinetics, drug interactions, and pharmacological actions. (5/16)

5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) belongs to a group of naturally-occurring psychoactive indolealkylamine drugs. It acts as a nonselective serotonin (5-HT) agonist and causes many physiological and behavioral changes. 5-MeO-DMT is O-demethylated by polymorphic cytochrome P450 2D6 (CYP2D6) to an active metabolite, bufotenine, while it is mainly inactivated through the deamination pathway mediated by monoamine oxidase A (MAO-A). 5-MeO-DMT is often used with MAO-A inhibitors such as harmaline. Concurrent use of harmaline reduces 5-MeO-DMT deamination metabolism and leads to a prolonged and increased exposure to the parent drug 5-MeO-DMT, as well as the active metabolite bufotenine. Harmaline, 5-MeO-DMT and bufotenine act agonistically on serotonergic systems and may result in hyperserotonergic effects or serotonin toxicity. Interestingly, CYP2D6 also has important contribution to harmaline metabolism, and CYP2D6 genetic polymorphism may cause considerable variability in the metabolism, pharmacokinetics and dynamics of harmaline and its interaction with 5-MeO-DMT. Therefore, this review summarizes recent findings on biotransformation, pharmacokinetics, and pharmacological actions of 5-MeO-DMT. In addition, the pharmacokinetic and pharmacodynamic drug-drug interactions between harmaline and 5-MeO-DMT, potential involvement of CYP2D6 pharmacogenetics, and risks of 5-MeO-DMT intoxication are discussed.  (+info)

Ionic mechanisms and receptor properties underlying the responses of molluscan neurones to 5-hydroxytryptamine. (7/16)

1. Molluscan neurones have been found to show six different types of response (three excitatory and three inhibitory) to the iontophoretic application of 5-hydroxytryptamine (5-HT). The pharmacological properties of the receptors and the ionic mechanisms associated with these responses have been analysed.2. Four of the responses to 5-HT (named A, A', B and C) are consequent upon an increase in membrane conductance whereas the other two (named alpha and beta) are caused by a decrease in membrane conductance.3. The A-response to 5-HT consists of a ;fast' depolarization due to an increase mainly in Na(+)-conductance; the A'-response is a ;slow' depolarization also associated with a Na(+)-conductance increase. Receptors mediating the A- and A'-depolarizations have different pharmacological properties and may exist side by side on the same neurone.4. Both the B- and C-responses are inhibitory. The B-response is a ;slow' hyperpolarization due to an increase in K(+)-conductance, the C-response is a fast hyperpolarization associated with an increase in Cl(-)-conductance.5. The alpha-response to 5-HT is a depolarization which becomes reduced in amplitude with cell hyperpolarization and reverses at -75 mV; it is caused by a decrease in K(+)-conductance. The beta-response is an hyperpolarization which increases in amplitude with cell hyperpolarization and reverses at -20/-30 mV. It results from a decrease in conductance to both Na(+) and K(+) ions.6. The receptors involved in the 5-HT responses associated with a conductance increase may be recognized by the action of specific antagonists: 7-methyltryptamine blocks only the A-receptors, 5-methoxygramine only the B-receptors and neostigmine only the C-receptors. Curare blocks the A- and C-receptors and bufotenine, the A-, A'- and B-receptors. No specific antagonists have yet been found for the 5-HT responses caused by a conductance decrease.7. The significance of the multiplicity of receptors is discussed. Their functional significance at synapses is analysed in the following paper.  (+info)

On the transmitter function of 5-hydroxytryptamine at excitatory and inhibitory monosynaptic junctions. (8/16)

1. Two symmetrical giant neurones located in the cerebral ganglion of Aplysia californica contain 4-6 p-mole 5-hydroxytryptamine (5-HT) and are able to synthesize it (Weinreich, McCaman, McCaman & Vaughn, 1973; Eisenstadt, Goldman, Kandel, Koike, Koester & Schwartz, 1973). Stimulation of each of these neurones evokes excitatory and inhibitory potentials in various cells of the ipsilateral buccal ganglion. In nine buccal neurones it evokes excitatory potentials, in other three, ;classical' inhibitory potentials and in one neurone an ;atypical' inhibitory potential.2. The connexion between the giant cerebral neurone and the cells receiving either an excitatory or a ;classical' inhibitory input from it are monosynaptic. TEA injection into the cerebral giant neurone, which prolongs the presynaptic spike, causes a gradual increase of both the excitatory and the inhibitory potentials. On the other hand, high Ca(2+) media, which block polysynaptic pathways, do not suppress these synaptic potentials.3. The iontophoretic application of 5-HT to the buccal neurones receiving excitatory input from the giant cerebral neurones evokes depolarizations showing the pharmacological properties of both A- and A'-responses to 5-HT (see preceding paper). Antagonists which block only the A-receptors (curare, 7-methyltryptamine, LSD 25) block partially the synaptic depolarizing potentials. Bufotenine, which blocks both the A- and A'-receptors, completely blocks the excitatory potentials. Thus, the post-synaptic membrane of these buccal neurones appears to be endowed with both A- and A'-receptors to 5-HT.4. The ;classical' inhibitory potentials elicited in three buccal neurones are hyperpolarizations which reverse at - 80 mV and are due to an increase in K(+)-conductance. The iontophoretic application of 5-HT to these post-synaptic neurones evokes hyperpolarizing B-responses which are also generated by an increase in K(+)-conductance. Antagonists which block the B-responses (bufotenine, methoxygramine) also block the inhibitory potentials.5. The ;atypical' inhibitory potential evoked in one buccal neurone consists in an hyperpolarization which increases in amplitude with cell hyperpolarization. Iontophoretic application of 5-HT to this buccal cell evokes an hyperpolarizing beta-response which also increases in amplitude with cell polarization and results from a decrease in both Na(+)- and K(+)- conductances. The monosynaptic character of the ;atypical' inhibitory potential is not yet fully proven.6. It can be concluded that the excitatory and inhibitory synaptic effects evoked in the buccal neurones by the stimulation of the 5-HT-containing-giant cerebral neurones are very likely mediated by 5-HT.  (+info)

Because of bufotenines low lipid solubility, bufotenine was once believed to be unable to cross the blood brain barrier in amounts sufficient to illicit hallucinogenic effects. This logic has been proven wrong. Bufotenines XLogP3 is 1.2, while mescalines XLogP3 is a mere 0.7. Mescaline has far less lipid solubility, and is still able to produce strong hallucinogenic effects. Modern tests have shown that bufotenine is a more potent hallucinogen requiring smaller doses for hallucinogenic activity.[7]. Bufotenine is active orally, sublingually, intrarectally, intranasally, by inhalation and injection.[7]. Doses as small as 8 mg injected intravenously were shown to produce hallucinogenic activity in human test subjects.[15]. Doses as small as 2 mg of the freebase inhaled as vapor have shown psychoactivity.[7] Doses as small as 8 mg of the freebase inhaled as vapor produced very clear hallucinogenic effects.[7]. Hallucinogenic drugs such as DMT and LSD bind and activate 5-HT2A and 5-HT2C receptor ...
5-MeO-DMT is a relatively less researched organic short-acting psychoactive indolealkylamine (Szabo et al., 2014; Yu, 2008). 5-MeO-DMT is found naturally in the bufotoxin of the Colorado River toad (Lyttle et al., 1996; Weil and Davis, 1994) and various plant species (Lycaeum, 2001; Ott, 2001; Shulgin and Shulgin, 2002; Smith, 1977), and is also synthetically produced (Hoshino and Shimodaira, 1936). When vaporized, 5-MeO-DMT causes potent visionary and auditory changes as well as alterations in time perception (Ott, 2001; Shulgin and Shulgin, 2002) and is rapidly metabolized, with a half-life of 12-19 min (Acosta-Urquidi, 2015; Shen et al., 2010). Experiential reports suggest that inhalation of vaporized 5-MeO-DMT engenders a potent range of experiences ranging from spiritual ecstasy and enlightenment, to feelings of near-death anxiety and panic (Erowid, 2018). To date, there are no controlled studies on the effects of 5-MeO-DMT in humans.. ...

In the late 1960s, LSD evangelist Art Kleps founded a psychedelic church called the Neo-American Church. The churchs newsletter was called Divine Toad Sweat.[3] In 1984, Bufo toad evangelist Albert Most revealed his Church of the Toad of Light with his publication of the book Bufo Alvarius: Psychedelic Toad of the Sonoran Desert. The Sonoran Desert is in New Mexico. This small booklet details how to use the Bufo toad for ritual and pleasure, as well as how to catch the Bufo alvarius toad, extract or milk the glandular secretions, dry them, and enjoy the smoked venom. Mosts book claims that 5-MeO-DMT (5-methoxy-N, N-dimethyltryptamine) is the active hallucinogen, not bufotenine. He is correct, as 5-MeO-DMT is the O-methylated version of bufotenine.[4] Again, it is important to mention that 5-MeO-DMT is present in only one of the more than 200 types of Bufo toads ...
Two mouse gene products that are molecularly related (∼90% identical) to the human and rat P2Y4 and the P2Y6 receptor genes were isolated and functionally expressed, and most likely they represent the murine P2Y4 and P2Y6 receptor orthologs. Pharmacological data indicate that the mouse P2Y4 and P2Y6 receptors are, in general, functionally similar to their rat and human orthologs. Both the (m)P2Y4 and (m)P2Y6 receptors couple to phospholipase C activation and calcium mobilization via pertussis toxin-insensitive, i.e., Gαq/11, mechanisms. The (m)P2Y4 receptor strictly recognizes nucleoside triphosphates, whereas the (m)P2Y6 receptor is most potently activated by UDP and is only very weakly activated by ADP.. A major difference between the mouse and human P2Y4 receptors is the effect of ATP on second messenger production. We previously reported that ATP had a weak and delayed effect on inositol phosphate formation in 1321N1 cells expressing the (h)P2Y4 receptor (Lazarowski et al., 1997b), and ...

Modulated effects of the PDGF ligand/receptor biology are a gene-diversification process that promotes response phenomena based on such genetic compilations as well-exemplified by fusion of genes and also as amplification of the PDGF receptor gene. Complications involving the dimerization of the PDGF polypeptide chains include the homologous pairing or AB heterologous pairing as incremental effects in PDGF ligand/receptor stimulus response involving tumor cells and stromal cells in autocrine and paracrine dysfunctionalities.. Aberrant PDGF signaling is primarily tumorigenic and it regulates the surrounding micro-environment; PDG is a major mitogen and chemoattractant for mesenchymal and glial cells[21]. The contrasting profiles of autocrine versus paracrine mechanisms involve a diverse cell series of subpopulation diversities that are potentially highly characterizable within the systems of cooperative pathway dynamics..

Amphetamines like MDMA, MDEA, MDA, and MBDB, among other relatives (see MDxx), are recreational drugs termed entactogens. They act as serotonin-norepinephrine-dopamine releasing agents (SNDRAs) and also agonize serotonin receptors such as those in the 5-HT2 subfamily. Fenfluramine, chlorphentermine, and aminorex, which are also amphetamines and relatives, were formerly used as appetite suppressants but were discontinued due to concerns of cardiac valvulopathy. This side effect has been attributed to their additional action of potent agonism of the 5-HT2B receptor. The designer drug 4-methylaminorex, which is an SNDRA and 5-HT2B agonist, has been reported to cause this effect as well. Many tryptamines, such as DMT, DET, DPT, DiPT, psilocin, and bufotenin, are SRAs as well as non-selective serotonin receptor agonists.[3] These drugs are serotonergic psychedelics, which is a consequence of their ability to activate the 5-HT2A receptor. αET and αMT, also tryptamines, are SNDRAs and non-selective ...
The binding properties of muscarinic cholinergic binding sites were investigated in rat cardiac membranes, using the labeled agonist [3H] oxotremorine-M ([3H]Oxo-M) and the labeled antagonist L-[benzilic-4,4-3H]quinuclidinyl benzilate (L-[3H]QNB). The binding of both tracers was inhibited stereospecifically by dexetimide and levitimide. [3H]Oxo-M labeled only high-affinity agonist binding sites, whereas L-[3H]QNB bound to high- and low-affinity agonist binding sites with equal affinity. Agonists were unable to induce negative cooperativity interactions by increasing the dissociation of labeled agonist or antagonist. Guanine nucleotides decreased markedly the affinity of high- and low-affinity binding sites for agonists, without affecting their affinity for antagonists. In the presence of a maximally effective concentration of GTP, all muscarinic receptors showed the same low affinity for agonists. Among these agonists, carbamylcholine and oxotremorine (but not pilocarpine) displayed a lower ...

The aim of this study was to investigate 5-MeO-DMT pharmacokinetic properties after intravenous or intraperitoneal administration of three different doses (2, 10, and 20 mg/kg) to CYP2D6-humanized (Tg-CYP2D6) and wild-type control mice. Systemic exposure [area under the curve (AUC)] to 5-MeO-DMT was increased nonproportionally with the increase in dose. The existence of nonlinearity in serum 5-MeO-DMT pharmacokinetics was clearly manifested by dose-normalized AUC values, which were approximately 1.5- to 2.0-fold (intravenous) and 1.8- to 2.7-fold (intraperitoneal) higher in wild-type or Tg-CYP2D6 mice dosed with 10 and 20 mg/kg 5-MeO-DMT, respectively, than those in
1 The aim of this study was to examine whether sodium nitroprusside (SNP)-induced relaxation of rat fundus longitudinal smooth muscle involves ryanodine-sensitive Ca2+ release. 2 SNP (300 nM-30 microM) elicited concentration-dependent relaxation of precontracted (1 microM carbachol) rat fundus, an effect almost abolished by the selective guanylyl cyclase inhibitor, 1H-[1,2,4]oxadiazolo[4,3-a]quinoxaline-1-one (ODQ, 10 microM). 3 SNP-mediated relaxations were almost abolished by 10 microM ryanodine. 4 SNP-mediated relaxations were also reduced by either 1 microM apamin (a selective small conductance Ca(2+)-sensitive K+ channel, SKCa, inhibitor) or the selective L-type Ca2+ channel inhibitor, nicardipine (3 microM). 5 SNP-induced relaxations were insensitive to 1 mM tetraethylammonium chloride (an inhibitor of large-conductance Ca(2+)-sensitive K+ channels) and 1 microM glibenclamide (an ATP-sensitive K+ channel inhibitor). 6 These data suggest that SNP-mediated fundus relaxation occurs via a ...

TCP has been shown to inhibit ,50% of human brain MAO-A after a three-day treatment with 10 mg/day (10). Clinical experience indicates that a small proportion of patients will get effects from that dose (I do not mean optimal or maximal effects, just noticeable ones), even sometimes significant postural hypotension - of the degree depicted in the bar graph in the MAOI_BP pdf. Illustrating BP changes at days 4 and 11.. It is generally supposed that approximately 85% inhibition is required for full clinical effect to occur.. Using the sound pharmacological principle of start low, go slow it is clearly prudent to start with no more than 20 mg per day, to assess the effect for 5 days by monitoring sitting and standing BP to ensure there is not an excessive postural drop at that dose - but note, near-maximum BP drop, on a constant dose, will take 10 days, or more, to develop. This is explained in the downloadable MAOI_BP pdf document the downloadable MAOI_BP pdf document here. NB I say sitting and ...

Bufotoxins are a family of toxic steroid lactones. They occur in the parotoid glands, skin and poison of many toads (genus Bufo) and other amphibians, and in some plants and mushrooms. The exact composition varies greatly with the specific source of the toxin. It can contain: 5-MeO-DMT, bufagins, bufalin, bufotalin, bufotenin, bufothionine, epinephrine, norepinephrine, and serotonin. The term bufotoxin can also be used specifically to describe the conjugate of a bufagin with suberylargine. The toxic substances found in toads can be divided by chemical structure in two groups: bufadienolides which are cardiac glycosides (e.g. bufotalin, bufogenin) tryptamine related substances (e.g. bufotenin) Toads known to secrete bufotoxin are:[citation needed] Bufo alvarius Bufo americanus Bufo arenarum Bufo asper Bufo blombergi Bufo boreas Bufo bufo Bufo bufo gargarizans Bufo Gutturalis Bufo formosus Bufo fowleri Rhinella marina (formerly Bufo marinus) Bufo melanostictus Bufo peltocephalus Bufo quercicus ...
There is increasing evidence that more than 70% of cancers including pancreatic, breast and prostate cancers as well as neurofibromatosis (NF) are highly addicted to abnormal activation of the Ser/Thr kinase PAK1 for their growth. So far FK228 is the most potent among the HDAC (histone deacetylase) inhibitors that block the activation of both PAK1 and another kinase AKT, downstream of PI-3 kinase. However, FK228 is still in clinical trials (phase 2) for a variety of cancers (but not for NF as yet), and not available for most cancer/NF patients. Thus, we have been exploring an alternative which is already in the market, and therefore immediately useful for the treatment of those desperate cancer/NF patients. Here we provide the first evidence that extracts of Chinese/ Japanese peppercorns (Zanthoxyli Fructus) from the plant Zanthoxylum piperitum called Hua Jiao/Sansho, block selectively the key kinase PAK1, leading to the downregulation of cyclin D1. Unlike FK228, these extracts do not ...
Three indole alkaloids that possess differing degrees of psychotropic/psychedelic activity have been reported as endogenous substances in humans; N,N-dimethyltryptamine (DMT), 5-hydroxy-DMT (bufotenine, HDMT), and 5-methoxy-DMT (MDMT). We have undertaken a critical review of 69 published studies reporting the detection or detection and quantitation of these compounds in human body fluids ...
Production of reactive oxygen species, often by NADPH (reduced form of nicotinamide adenine dinucleotide phosphate) oxidases, plays a role in the signaling responses of cells to many receptor stimuli. Here, we describe the function of the calcium-dependent, nonphagocytic NADPH oxidase Duox1 in primary human CD4+ T cells and cultured T cell lines. Duox1 bound to inositol 1,4,5-trisphosphate receptor 1 and was required for early T cell receptor (TCR)-stimulated production of hydrogen peroxide (H2O2) through a pathway that was dependent on TCR-proximal kinases. Transient or stable knockdown of Duox1 inhibited TCR signaling, especially phosphorylation of tyrosine-319 of ζ chain-associated protein kinase of 70 kilodaltons (ZAP-70), store-operated entry of calcium ions (Ca2+), and activation of extracellular signal-regulated kinase. The production of cytokines was also inhibited by knockdown of Duox1. Duox1-mediated inactivation of Src homology 2 domain-containing protein tyrosine phosphatase 2 ...

Serotonin and dopamine stimulate distinct postsynaptic sensitive adenylate cyclases in homogenates of various brain areas in newborn rats [Enjalbert, A., Bourgoin, S., Hamon, M., Adrien, J. & Bockaert, J. (1978) Mol. Pharmacol., 14, 000-000]. However, maximal effects of dopamine and serotonin on the adenylate cyclase activity in the striatum and the hypothalamus were not strictly additive. In fact, in striatum serotonin inhibited the dopamine-sensitive adenylate cyclase noncompetitively. Conversely, the maximal effects of serotonin and l-isoproterenol (a pure beta adrenergic agonist) on adenylate cyclase activity in homogenates of the cerebral cortex were strictly additive. Classical serotoninergic agonists [D-lysergic acid diethylamide (LSD), bufotenine, 5-methoxy-N,N-dimethyltryptamine] activated the adenylate cyclase in collicular homogenates. All but LSD were ineffective on the beta adrenergic-sensitive adenylate cyclase in C6 glioma cells. The antagonists tested were not specific for the ...
Bioactive compounds derived from plant natural compounds have proven to be valuable sources of metabolites which can seldom be obtained from other sources. Plants belonging to the genus Zanthoxylum have been valued across various cultures for their curative properties. Zanthoxylum armatum DC., belonging to the family Rutaceae is extensively used in traditional practices in North-Eastern India and neighbouring regions including South-East Asia. However, the potential cytogenetic effects of Zanthoxylum armatum under in vivo conditions, and their causative mechanisms have not yet been studied in detail. The current study was undertaken to evaluate the cytotoxic and genotoxic potential of aqueous extracts of fruits of Z. armatum under in vivo conditions using the Allium test. Physiological and cellular data indicate that the extracts induce clumped chromosomes at metaphase stage of cell division coupled with mitotic arrest. Electron microscopy data reveal membrane damage of cellular organelles, chromatin
Attila Szabo1,2, Attila Kovacs3, Ede Frecska3, Eva Rajnavolgyi1,2. 1Department of Immunology, Faculty of Medicine, University of Debrecen, Debrecen, Hungary. 2Research Centre for Molecular Medicine, University of Debrecen, Debrecen, Hungary. 3Department of Psychiatry, Faculty of Medicine, University of Debrecen, Debrecen, Hungary. Abstract. The orphan receptor sigma-1 (sigmar-1) is a transmembrane chaperone protein expressed in both the central nervous system and in immune cells. It has been shown to regulate neuronal differentiation and cell survival, and mediates anti-inflammatory responses and immunosuppression in murine in vivo models. Since the details of these findings have not been elucidated so far, we studied the effects of the endogenous sigmar-1 ligands N,N-dimethyltryptamine (NN-DMT), its derivative 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) and the synthetic high affinity sigmar-1 agonist PRE-084 hydrochloride on human primary monocyte-derived dendritic cell (moDCs) activation ...
A molecular dynamics study of liquid N,N-dimethyl formamide has been carried out. Orientational correlation functions suggest a stacked antiparallel ordering at short distances (, 5Å) and a perpendicular + configuration at intermediate distances. The proposed ordering is in agreement with the recent 13C NMR results of Konrat and Sterk and suggests a stronger association of CH3(t) with O than of CH3(c) with O. Both the translational and the rotational motions are anisotropic. The diffusion constants for rotation along the different directions are different, in agreement with the NMR results. ...
Recent popularity in studying the effects of psychedelic drugs on brain function and for drug-abuse treatment has continued with mini-brain organoid technology. A group of Brazilian scientists introduced 5-MeO-DMT, a type of dimethyltryptamine, to mini-brains from stem cells in rats.. The effects of entheogens, commonly known as psychedelics, have been found to be effective treatments for curbing and eliminating depression and drug addiction, in this particular study. It found direct evidence, showing how 5-MeO-DMT upregulates synaptic formation and function, while downregulating pathways that are associated with inflammation and substance abuse. Not only did it influence these functions, but it also influenced proteins responsible for brain plasticity, a term used to describe the brains ability to change, often in response to learning.. It is believed that DMT is naturally produced in the pineal gland in our brains. 5-MeO-DMT is structurally similar to serotonin and melatonin, and can ...

In order to hydroxylate L-tryptophan, the cofactor tetrahydrobiopterin (THB) must first react with oxygen and the active site iron of tryptophan hydroxylase. This mechanism is not well understood, but two mechanisms have been proposed: 1. A slow transfer of one electron from the THB to O2 could produce a superoxide which could recombine with the THB radical to give 4a-peroxypterin. 4a-peroxypterin could then react with the active site iron (II) to form an iron-peroxypterin intermediate or directly transfer an oxygen atom to the iron. 2. O2 could react with the active site iron (II) first, producing iron (III) superoxide which could then react with the THB to form an iron-peroxypterin intermediate. Iron (IV) oxide from the iron-peroxypterin intermediate is selectively attacked by a double bond to give a carbocation at the C5 position of the indole ring. A 1,2-shift of the hydrogen and then a loss of one of the two hydrogen atoms on C5 reestablishes aromaticity to furnish ...

In order to hydroxylate L-tryptophan, the cofactor tetrahydrobiopterin (THB) must first react with oxygen and the active site iron of tryptophan hydroxylase. This mechanism is not well understood, but two mechanisms have been proposed: 1. A slow transfer of one electron from the THB to O2 could produce a superoxide which could recombine with the THB radical to give 4a-peroxypterin. 4a-peroxypterin could then react with the active site iron (II) to form an iron-peroxypterin intermediate or directly transfer an oxygen atom to the iron. 2. O2 could react with the active site iron (II) first, producing iron (III) superoxide which could then react with the THB to form an iron-peroxypterin intermediate. Iron (IV) oxide from the iron-peroxypterin intermediate is selectively attacked by a double bond to give a carbocation at the C5 position of the indole ring. A 1,2-shift of the hydrogen and then a loss of one of the two hydrogen atoms on C5 reestablishes aromaticity to furnish ...
