Tryptophan psilocybin

Once this ESR wave has been detected, it will be possible to amplify it within the neural circuits by channeling it through the harmine complex i.e., by imitating the psilocybin ESR with the voice, causing the amplified sound to strike a harmonic tone with the harmine metabolizing in the brain and thereby exciting the harmine ESR. Since harmine complexes are merely further down the same bio-synthetic pathway that converts tryptophane into psilocybin, it is possible to consider the ESR tone of psilocybin as a harmonic overtone of harmine and vice versa. 

In this pathway, L-tryptophan is enzymatically transferred to tryptamine and subsequently, through the activity of SAM, to psilocin. By the reaction of phosphorylation, psilocin is converted into psilocybin (Figure 39). 

The a for the structural development of psilocin and psilocybin is L-tryptophan and the j3 is tryptamine. Psilocin is A and psilocybin is P. A and P are the main alkaloids in hallucinogenic mushrooms belonging to the genus Psilocybe. 

Alkaloids from tryptophan. The alkaloid harmine, which is found in several families of plants, can be formed from tryptophan and acetaldehyde (or pyruvate) in the same manner as is indicated for the formation of papaverine in Fig. 25-10. Some other characteristic plant metabolites such as psilocybine, an hallucinogenic material from the mushroom... 

This compound cluster exhibits a two-ring, "open-chained, indolic chemical structure, and in contrast to other psychedelics it is all but inactive when taken orally unless accompanied by certain other compounds. Shortacting tryptamines are closely related to neurotransmitters (such as bufotenine), to MDA (a major botanical source of the snuffs belongs to the nutmeg family), to tryptophan (an essential amino acid produced in human digestion of proteins) and to psilocybin and psilocin (which are tryptamines of longer duration). DMT, the simplest member, occurs normally in the blood, brain and (in higher concentrations) in the cerebrospinal fluid. 

In P. semperviva it has been demonstrated that tryptophan is a precursor of psilocybin (93a). It was simultaneously suggested that a similar oxidation of tryptophan or a tryptophan metabolite at the 4-position constitutes an important intermediate stage in the biosynthesis of the ergot alkaloids from tryptophan. 

Our reasoning regarding the ESR of tryptamines was based on a similar idea. The psilocybin complex, the methylated tryptamines, and the har-mine complex are all biosynthetically derived in nature from tryptophan... 

Psilocin, the dephosphorylated derivative of psilocybin, is shown here in its relation to tryptamine. Note that N, N-dimethyltryptamine is closely related to psilocin. That tryptophan is a precursor of psilocybin in living organisms has been shown by Brack et al. (1961). Psilocybin and trace amounts of psilocin have been extracted from Stropharia cubensisby Hofmann et al. 

Tryptophan (fig. 8) is one of the twenty amino acids used by all of life on Earth to build proteins. Although plants, fungi, bacteria, and some other organisms can biosynthesize tryptophan from smaller carbon molecules, humans cannot and must ingest tryptophan as part of their diet. That is, tryptophan is one of the essential amino acids. In fungi and plants, tryptophan is the chemical precursor for the biosynthesis of tryptamines such as DMT and psilocybin. In humans and other animals, tryptophan is the precursor for the synthesis of the neurotransmitter serotonin, 5-hydroxytryptamine (5-HT fig. 9). 

In terms of cultivation parameters and nutrients, the psychotropic species are no different from table mushrooms and other common gilled mushrooms. For that reason, Oss and Oeric s speculations about extra-terrestrial origins of these species clearly belong into the realm of fables. In addition, psilocybin and psilocin are substances that can be derived from tryptophan by means of discemable reactions indeed, the amino acid tryptophan in its free form has been found in a large number of mushroom species. 

In the mid-1960s, Psilocybe cubensis became the species of choice for experiments that made use of submersed fermentation to investigate the biosynthesis of psilocybin from tryptophan and other precursors. We should note in this context that around the same time, this technique was also used to obtain mycelial pellets of the species Psilocybe baeocystis Singer Smith, providing the material for the first-ever isolation of baeocystin from mushroom tissue.

Psilocybin (4-phosphoryloxy-iV,A -dimethyltryptamine) (9.31) and the parent alcohol, psilocin, were first isolated from the Mexican mushroom Psilocybe mexicana by Hofmann in 1959. Since then these hallucinogenic metabolites have been reported in more than 30 species of this genus and its relatives. The highest concentration (over 0.5% dry weight) of psilocybin has been detected in Conocybe cyanopus and Psilocybe semilanceata. The hallucinogenic properties of these organisms have led to their colloquial name as magic mushrooms . P. semilanceata, which is quite widespread in Europe, is sometimes known as the Liberty Cap. A biosynthetic sequence from tryptophan to psilocybin has been established. 

Another test which is often given in mushroom manuals is treating the exposed tissues with Metol, a chemical used in photo developers. It hastens the blueing of psilocybin mushrooms, and supposedly one can do a blueing test with it in a few minutes that would otherwise take 30 minutes or more. Any mushroom, however, which contains indolic substances of any sort will respond positively to this test. Since indole-based amino acids such as tryptophan are found in most living organisms this test is rather useless. 

The biosynthesis of psilocybin has not yet been fully clarified, although some details of the pathway seem to be unquestionable. First, Brack et al. (161) found that psilocybin was biosynthesized from tryptophan, and then Agurell et al. (162) demonstrated that Psilocybe cubensis effectively incorporated tryptamine into psilocybin as well. In later studies, Agurell and Nilsson (163,164), using several precursors specifically labeled with C and H, showed that tryptamine and psilocin are apparent interme-... 

The latter possibility was reconsidered more recently by Stijve (755, 765). According to his observations, psilocybin in Psilocybe semilance-ata ind in five Inocybe species was accompanied by its precursor baeo-cystine, which may indicate that during biosynthesis phosphorylation precedes methylation in conformity with the sequence tryptophan tryptamine — 4-hydroxytryptamine norbaeocystine baeocystine ... 

Alkaloids occur in many other botanical families. Moreover, these alkaloids, derived from L-tryptophan, occur in mushrooms genera Hericium mushrooms (Hericium erinaceum), Psilocybe mushrooms (Psilocybe), Con-ocybe mushrooms (Conocybe), Haymaker s mushrooms (Panaeolus), and Stoparia mushrooms (Stoparia). Hericirine, serotonin, psilocin, and psilocybin are basic alkaloids derived from these mushrooms (Figure 1.19). They... 

Tryptophan and tryptamine are incorporated into psilocybin. Psilocin is an apparent intermediate for the biosynthesis of psilocybin (Antkowiak and Antkowiak, 1990). 

Psilocybin is regarded as tryptamine compotmd based on its biosynthesis route and precursor. Being a tryptamine compotmd, the chemical stmcture is derived from the amino acid tryptophan (5) which has a ring configuration, simply known as... 

The shikimic acid pathway leading to the production of chorismic acid is regulated in the cytosol of the fungal cells. Cytosol or intracellular fluid (cytoplasmic matrix) is a complex mixture of substances dissolved in water. These include ions (such as calcium, sodium, and potassium), macromolecules, and large complexes of enzymes that act together to carry out metabolic pathways. Production of chorismic acid in the cytosol is ultimately utilized in the synthesis of folate, ubiquinone, and amino acids, the most important of which is tryptophan which plays a major role in the biosynthesis of psilocybin. 

Earlier findings published in 1961 [107] suggested that psilocybin is finally been synthesize from tryptophan. The hypothesis was based on the results obtained from still cultures of Psilocybe semperviva. Subsequent studies on the subject carried out using Psilocybe cubensis under submerged cultural condition also supported this hypothesis that psilocybin may biosynthetically derive from tryptophan and tryptamine [108]. More details were then published to clarify the sequence of events which leads from tryptophan to psilocybin by incorporating and C " - labeled hypothetical intermediates (such as DL-Tryptophan- H, Tryptamine- V,... 

A-methyltryptamine-C - H, Af,Af-Dimethyltryptamine- C- H, 4-hydroxytrypta-mine- C- H, Psilocin- H, DL-4-OH-Tryptophan- H) into psilocybin in submerged cultures of Psilocybe cubensis [109, 110]. Other reports [111, 112] indicated no effect or influence of tryptophan on the biosynthesis of psilocybin when added in the culture medium during submerged fermentation of Psilocybe cubensis and Psilocybe baeocystis. It can be concluded from the results of most findings that tryptophan has to be modified by decarboxylation, methylation of the amino group, hydroxylation of the 4-position of the indole moiety, and phosphorylation of the 4-hydroxyindole moiety for the production of psilocybin with below sequence [108-110,113],... 

The radioactive tryptamine is observed to function as a better precursor than the tryptophan and 4-hydroxytryptophan in submerged culture of Psilocybe cubensis [113] it is reasonable to conclude that the decarboxylation of tryptophan to tryptamine is the most crucial step in the biosynthetic pathway. This step is highly sensitive to feedback inhibition due to allosteric enzymes. It is believed that as the concentration of psilocin increases in the culture media, it starts inhibiting further conversion of tryptophan to tryptamine, and as a result tryptophan will not be converted to tryptamine, and thus no psilocin or psilocybin is...
