TL;DR: Two low-molecular-weight compounds were isolated from the parotid gland secret of the toad Bufo bufo, which by absorption spectra and HPLC-MS/MS chromatography data correspond to di- and trimethyl derivatives of serotonin (5-hydorxytryptamine).
Abstract: Two low-molecular-weight compounds were isolated from the parotid gland secret of the toad Bufo bufo, which by absorption spectra and HPLC-MS/MS chromatography data correspond to di- and trimethyl derivatives of serotonin (5-hydorxytryptamine): bufotenine (confirmed by counter synthesis) and bufotenidine (5-HTQ). In experiments on competitive radioligand binding, these compounds showed a higher affinity and selectivity for neuronal α7 nicotinic acetylcholine receptors compared with the muscular cholinergic receptors. The most efficient compound in terms of binding value was bufotenine, the efficiency of 5-HTQ was an order of magnitude lower, and the minimal activity was exhibited by serotonin.
TL;DR: Serotonin (5-hydroxytryptamine, 5-HT) seems to mediate the effects of morphine in the intestine, and bufotenidine, a neural tryptaminic receptor blocking agent blocks the results of both 5- HT and morphine on intestinal motility.
TL;DR: In this paper, the authors have disclosed compositions containing two purified toad secretion tryptamines chosen from the following 5-MeO-DMT, 5-meO-NMT and 5-Methoxytryptamine categories.
Abstract: Disclosed are compositions containing two purified toad secretion tryptamines chosen from the following 5-MeO-DMT, 5-MeO-NMT, 5-Methoxytryptamine, bufobutanoic Acid, bufobutarginine, bufoserotonin A, bufoserotonin B, bufoserotonin C, bufotenidine, bufotenin, bufotenin Oxide, bufotenine-O-Sulphate, bufoviridine, dET, dMT, n-Acetylserotonin, n'-Formylserotonin, n- Methylserotonin, o-Methylbufoviridine, serotonin, tryptamine, and bufopyramide or the salts of these toad secretion tryptamines. The disclosure also relates to formulations, including pharmaceutical formulations, of such a composition and an excipient. Pharmaceutical formulation further containing a therapeutically effective amount of a serotonergic drug, a purified psilocybin derivative, a purified cannabinoid, or a purified terpene a disclosed. Also disclosed are methods of regulating the activity of a neurotransmitter receptor and methods of treating a psychological disorder, a compulsive disorder, or a depressive disorder.
