Determination of harmane and harmine in human blood using reversed-phased high-performance liquid chromatography and fluorescence detection. (1/89)

A number of tremorogenic beta-carboline alkaloids have been found in common plant-derived foodstuffs, beverages, and inhaled substances. Because of their natural presence in the food chain, there is a growing concern regarding the potential risks of certain essential tremors associated with the long-term, low-level dietary exposure to these alkaloids. The purpose of this study was to develop an effective analytical method to determine blood levels of two major beta-carboline derivatives, harmane and harmine. Human blood was extracted with ethyl acetate and methyl-t-butyl ether (2:98) under an alkaline condition. After evaporation of organic solvent, the samples were reconstructed in methanol. The samples were fractionated on a 250 x 4.6-mm C18 reversed-phase column with an isocratic mobile system consisting of 17.5 mM potassium phosphate buffer (ph 6.5) and methanol (30:70), followed by an on-line fluorescence detection. The method had the detection limit to determine 206 and 81 pg/ml of harmane and harmine, respectively, in 10 ml of human blood. The intraday precision (C.V.) at 25 ng/ml was less than 6.7 and 3.4% for harmane and harmine, respectively. The interday precision was 7.3% for harmane and 5.4% for harmine. The method has proven sensitive, reproducible, and thus useful for both laboratory and clinical studies of beta-carboline toxicities.  (+info)

Harmane produces hypotension following microinjection into the RVLM: possible role of I(1)-imidazoline receptors. (2/89)

The beta-carboline, harmane (0.1 - 1.0 nmol) produces dose dependent hypotension when microinjected unilaterally into the rostral ventrolateral medulla (RVLM) of the anaesthetized rat. The potency of harmane on blood pressure is similar to that of the imidazoline, clonidine. The hypotensive effects of both clonidine and harmane are reversed by microinjection of the relatively I(1)-receptor selective antagonist efaroxan (20 nmol). These results are consistent with harmane acting at an I(1)-receptor in the RVLM. This is the first report of an endogenous ligand for I(1)-receptors that has central effects on blood pressure.  (+info)

Comparative study on the vasorelaxant effects of three harmala alkaloids in vitro. (3/89)

Three psychological active principles from the seeds of Peganum harmala L., harmine, harmaline and harmalol, showed vasorelaxant activities in isolated rat thoracic aorta preparations precontracted by phenylephrine or KCl with rank order of relaxation potency of harmine > harmaline > harmalol. The vasorelaxant effects of harmine and harmaline (but not harmalol) were attenuated by endothelium removal or pretreatment with a nitric oxide (NO) synthase Nomega-nitro-L-arginine methyl ester. In cultured rat aortic endothelial cells, harmine and harmaline (but not harmalol) increased NO release, which was dependent on the presence of external Ca2+. In endothelium-denuded preparations, pretreatment of harmine, harmaline or harmalol (3-30 microM) inhibited phenylephrine-induced contractions in a non-competitive manner. Receptor binding assays indicated that all 3 compounds interacted with cardiac alpha1-adrenoceptors with comparable affinities (Ki value around 31 - 36 microM), but only harmine weakly interacted with the cardiac 1,4-dihydropyridine binding site of L-type Ca2+ channels (Ki value of 408 microM). Therefore, the present results suggested that the vasorelaxant effects of harmine and harmaline are attributed to their actions on the endothelial cells to release NO and on the vascular smooth muscles to inhibit the contractions induced by the activation of receptor-linked and voltage-dependent Ca2+ channels. The vasorelaxant effect of harmalol was not endothelium-dependent.  (+info)

Effects of reserpine on the adrenal medulla of the spontaneously hypertensive rat. (4/89)

1. Reserpine administration resulted in a larger initial decline in adrenal catecholamines in spontaneously hypertensive rats (SHR) than in normotensive Wistar rats (NWR); the difference was eliminated by pretreatment with cholisdondamine. 2. Reserpine also produced a larger increase in SHR catecholamines and dopamine beta-hydroxylase several days later; chlorisondamine pretreatment did not prevent the increases, although it did slightly slow the increases. 3. Vesicles from SHR, or NWR incubated with reserpine in vitro demonstrated equivalent inhibition of adenosine 5'-triphosphate (ATP)-Mg-2+-stimulated adrenaline uptake. 4. Recovery of uptake was more rapid in SHR than in NWR after reserpine inhibition, and this was associated with a burst of new vesicle synthesis in the SHR; chlorisondamine pretreatment reduced the number of new, immature vesicles in reserpine-treated SHR. 5. Both SHR and NWR secreted equal proportions of their adrenal catecholamine contents after nicotine administration. 6. These data suggest that the sympatho-adrenal system of the SHR exhibits an enhanced reflex response to reserpine but that reserpine is equally effective in SHR and NWR in producing blockade of vesicular catecholamine transport; these alterations can affect markedly the actions of autonomic drugs in the SHR.  (+info)

Inhibitors alter the spectrum and redox properties of monoamine oxidase A. (6/89)

Monoamine oxidase A (MAO A) catalyses the oxidation of both neurotransmitter and ingested amines. The mechanism of catalysis involves the covalently bound FAD cofactor. Although substrates and inhibitors alter the thermodynamic and kinetic properties of the flavin, how the ligands interact with the flavin is unknown. This work characterises the spectral changes that occur on inhibitor binding to MAO A and examines how the binding influences the flavin. The inhibitors, D-amphetamine, harmine, tetrindole, and befloxatone all induce similar (but not identical) changes in the spectrum of MAO A, consistent with stacking of inhibitor with the flavin in the active site. D-Amphetamine, harmine, and tetrindole stabilise the semiquinone form of FAD during reduction of MAO A by dithionite and no further reduction of these inhibitor-MAO A complexes has been observed. In contrast, semiquinone is never observed during reduction of the befloxatone-MAO A complex. Instead, partial reduction directly to the FADH(2) form occurs extremely slowly. Thus, inhibitor binding has a strong, structure-dependent influence on the environment of the flavin that alters its electronic properties.  (+info)

Contribution of individual cytochrome P450 isozymes to the O-demethylation of the psychotropic beta-carboline alkaloids harmaline and harmine. (7/89)

The psychotropic beta-carboline alkaloids, showing high affinity for 5-hydroxytryptamine, dopamine, benzodiazepine, and imidazoline receptors and the stimulation of locus coeruleus neurons, are formed endogenously from tryptophan-derived indolealkylamines through the Pictet-Spengler condensation with aldehydes in both plants and mammals. Cytochromes P450 1A1 (18.5), 1A2 (20), and 2D6 (100) catalyzed the O-demethylation of harmaline, and CYP1A1 (98.5), CYP1A2 (35), CYP2C9 (16), CYP2C19 (30), and CYP2D6 (115) catalyzed that of harmine (relative activities). The dehydrogenation/aromatization of harmaline to harmine was not carried out by aromatase (CYP19), CYP1A2, CYP2C9, CYP2D6, CYP3A4, pooled recombinant cytochromes P450, or human liver microsomes (HLMs). Kinetic parameters were calculated for the O-demethylations mediated by each isozyme and by pooled HLMs. K(cat) (min(-1)) and K(m) Awake M) values for harmaline were: CYP1A1, 10.8 and 11.8; CYP1A2, 12.3 and 13.3; CYP2C9, 5.3 and 175; CYP2C19, 10.3 and 160; and CYP2D6, 39.9 and 1.4. Values for harmine were: CYP1A1, 45.2 and 52.2; CYP1A2, 9.2 and 14.7; CYP2C9, 11.9 and 117; CYP2C19, 21.4 and 121; and CYP2D6, 29.7 and 7.4. Inhibition studies using monoclonal antibodies confirmed that CYP1A2 and CYP2D6 were the major isozymes contributing to both harmaline (20% and 50%, respectively) and harmine (20% and 30%) O-demethylations in pooled HLMs. The turnover numbers for CYP2D6 are among the highest ever reported for a CYP2D6 substrate. Finally, CYP2D6-transgenic mice were found to have increased harmaline and harmine O-demethylase activities as compared with wild-type mice. These findings suggest a role for polymorphic CYP2D6 in the pharmacology and toxicology of harmine and harmaline.  (+info)

Microbial metabolites of harman alkaloids. (8/89)

Several microorganisms showed the ability to transform the harman alkaloids, harmaline (1), harmalol (2) and harman (5). Harmaline (1) and harmalol (2) were converted by Rhodotorula rubra ATCC 20129 into the tryptamines, 2-acetyl-3-(2-acetamidoethyl)-7-methoxyindole (3) and 2-acetyl-3-(2-acetamidoethyl)-7-hydroxyindole (4), respectively. Harman (5) was biotransformed by Cunninghamella echinulata NRRL 3655 into 6-hydroxyharman (6) and harman-2-oxide (7).  (+info)

Harmine is defined medically as an alpha-carboline derivative that is present in various plants including the seeds of Peganum harmala and the bark of Banisteriopsis caapi. It functions as an monoamine oxidase inhibitor (MAOI) and has been used in traditional medicine for its psychoactive properties. It has also been studied for potential anti-cancer, anti-inflammatory, and neuroprotective effects.

Harmane, also known as harmaline, is a naturally occurring psychoactive compound found in several plants, including the seeds of the Syrian rue (Peganum harmala) and the bark of the African pinwheel cactus (Adenium obesum). It is an alkaloid with beta-carboline structure.

In a medical context, harmaline has been studied for its potential effects on the central nervous system. It acts as a reversible monoamine oxidase inhibitor (MAOI), which means it can increase the levels of certain neurotransmitters in the brain by preventing their breakdown. This property has led to some research into its use as a treatment for depression and other neurological disorders, although it is not currently approved for medical use in this capacity due to potential side effects and toxicity concerns.

It's important to note that harmaline can have dangerous interactions with certain medications and foods, particularly those containing tyramine, which can lead to a hypertensive crisis. Therefore, its use should only be under the supervision of a qualified medical professional.

"Peganum" is the name of a genus of plants, specifically those in the family Nitrariaceae. The most well-known species in this genus is "Peganum harmala," also known as Syrian rue or esfand. This plant has been used in traditional medicine in various cultures for its psychoactive and hallucinogenic properties, as well as for treating ailments such as rheumatism, skin conditions, and gastrointestinal disorders. However, it can also have toxic effects and should be used with caution. It's important to note that the use of Peganum in medical treatment is not widely accepted or studied in modern Western medicine.

Banisteriopsis is a genus of flowering plants in the family Malpighiaceae, native to tropical America. The most well-known species is Banisteriopsis caapi, which is used to prepare a psychoactive beverage called ayahuasca, also known as yage. Ayahuasca is traditionally used for spiritual and religious purposes by indigenous peoples of the Amazon basin.

The active components in Banisteriopsis caapi are harmala alkaloids, including harmine, harmaline, and tetrahydroharmine, which act as reversible inhibitors of monoamine oxidase (MAOIs). When combined with DMT-containing plants, such as Psychotria viridis, the MAOIs allow the DMT to be orally active, resulting in a powerful psychedelic experience.

It is important to note that the use of ayahuasca and other substances containing DMT and MAOIs can have serious health consequences and should only be undertaken under the guidance of experienced practitioners in a safe and controlled setting.

Carbolines are a type of chemical compound that contain a carbazole or dibenzopyrrole structure. These compounds have a variety of uses, including as pharmaceuticals and dyes. Some carbolines have been studied for their potential medicinal properties, such as their ability to act as antioxidants or to inhibit the growth of certain types of cells. However, it is important to note that many carbolines are also known to be toxic and can cause harm if ingested or otherwise introduced into the body. As with any chemical compound, it is essential to use caution when handling carbolines and to follow all safety guidelines to minimize the risk of exposure.

Alkaloids are a type of naturally occurring organic compounds that contain mostly basic nitrogen atoms. They are often found in plants, and are known for their complex ring structures and diverse pharmacological activities. Many alkaloids have been used in medicine for their analgesic, anti-inflammatory, and therapeutic properties. Examples of alkaloids include morphine, quinine, nicotine, and caffeine.

Monoamine oxidase inhibitors (MAOIs) are a class of drugs that work by blocking the action of monoamine oxidase, an enzyme found in the brain and other organs of the body. This enzyme is responsible for breaking down certain neurotransmitters, such as serotonin, dopamine, and norepinephrine, which are chemicals that transmit signals in the brain.

By inhibiting the action of monoamine oxidase, MAOIs increase the levels of these neurotransmitters in the brain, which can help to alleviate symptoms of depression and other mood disorders. However, MAOIs also affect other chemicals in the body, including tyramine, a substance found in some foods and beverages, as well as certain medications. As a result, MAOIs can have serious side effects and interactions with other substances, making them a less commonly prescribed class of antidepressants than other types of drugs.

MAOIs are typically used as a last resort when other treatments for depression have failed, due to their potential for dangerous interactions and side effects. They require careful monitoring and dosage adjustment by a healthcare provider, and patients must follow strict dietary restrictions while taking them.

Apomorphine is a non-selective dopamine receptor agonist, which means that it activates dopamine receptors in the brain. It has a high affinity for D1 and D2 dopamine receptors and is used medically to treat Parkinson's disease, particularly in cases of severe or intractable motor fluctuations.

Apomorphine can be administered subcutaneously (under the skin) as a solution or as a sublingual (under the tongue) film. It works by stimulating dopamine receptors in the brain, which helps to reduce the symptoms of Parkinson's disease such as stiffness, tremors, and difficulty with movement.

In addition to its use in Parkinson's disease, apomorphine has also been investigated for its potential therapeutic benefits in other neurological disorders, including alcohol use disorder and drug addiction. However, more research is needed to establish its safety and efficacy in these conditions.
