Abstract
While psychedelics may have therapeutic potential for treating mental health disorders such as depression, further research is needed to better understand their biological effects and mechanisms of action when considering the development of future novel therapy approaches. Psychedelic research could potentially benefit from the integration of metabonomics by proton nuclear magnetic resonance (1H NMR) spectroscopy which is an analytical chemistry-based approach that can measure the breakdown of drugs into their metabolites and their metabolic consequences from various biofluids. We have performed a systematic review with the primary aim of exploring published literature where 1H NMR analysed psychedelic substances including psilocin, lysergic acid diethylamide (LSD), LSD derivatives, N,N-dimethyltryptamine (DMT), 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) and bufotenin. The second aim was to assess the benefits and limitations of 1H NMR spectroscopy-based metabolomics as a tool in psychedelic research and the final aim was to explore potential future directions. We found that the most current use of 1H NMR in psychedelic research has been for the structural elucidation and analytical characterisation of psychedelic molecules and that no papers used 1H NMR in the metabolic profiling of biofluids, thus exposing a current research gap and the underuse of 1H NMR. The efficacy of 1H NMR spectroscopy was also compared to mass spectrometry, where both metabonomics techniques have previously shown to be appropriate for biofluid analysis in other applications. Additionally, potential future directions for psychedelic research were identified as real-time NMR, in vivo 1H nuclear magnetic resonance spectroscopy (MRS) and 1H NMR studies of the gut microbiome. Further psychedelic studies need to be conducted that incorporate the use of 1H NMR spectroscopy in the analysis of metabolites both in the peripheral biofluids and in vivo to determine whether it will be an effective future approach for clinical and naturalistic research.

The phylogeny of the Casque-headed Treefrogs (Hylidae: Hylinae: Lophyohylini). Cladistics 2021; 37:36-72.

Abstract
The South American and West Indian Casque-headed Treefrogs (Hylidae: Hylinae: Lophyohylini) include 85 species. These are notably diverse in morphology (e.g. disparate levels of cranial hyperossification) and life history (e.g. different reproductive modes, chemical defences), have a wide distribution, and occupy habitats from the tropical rainforests to semiarid scrubland. In this paper, we present a phylogenetic analysis of this hylid tribe based on sequence fragments of up to five mitochondrial (12S, 16S, ND1, COI, Cytb) and six nuclear genes (POMC, RAG-1, RHOD, SIAH, TNS3, TYR). We included most of its species (> 96%), in addition to a number of new species. Our results indicate: (i) the paraphyly of Trachycephalus with respect to Aparasphenodon venezolanus; (ii) the nonmonophyly of Aparasphenodon, with Argenteohyla siemersi, Corythomantis galeata and Nyctimantis rugiceps nested within it, and Ap. venezolanus nested within Trachycephalus; (iii) the polyphyly of Corythomantis; (iv) the nonmonophyly of the recognized species groups of Phyllodytes; and (v) a pervasive low support for the deep relationships among the major clades of Lophyohylini, including C. greeningi and the monotypic genera Itapotihyla and Phytotriades. To remedy the nonmonophyly of Aparasphenodon, Corythomantis, and Trachycephalus, we redefined Nyctimantis to include Aparasphenodon (with the exception of Ap. venezolanus, which we transferred to Trachycephalus), Argenteohyla, and C. galeata. Additionally, our results indicate the need for taxonomic work in the following clades: (i) Trachycephalus dibernardoi and Tr. imitatrix; (ii) Tr. atlas, Tr. mambaiensis and Tr. nigromaculatus; and (iii) Phyllodytes. On the basis of our phylogenetic results, we analyzed the evolution of skull hyperossification and reproductive biology, with emphasis on the multiple independent origins of phytotelm breeding, in the context of Anura. We also analyzed the inter-related aspects of chemical defences, venom delivery, phragmotic behaviour, co-ossification, and prevention of evaporative water loss.

Abstract
We report on the predation of a veined treefrog (Trachycephalus venulosus) and an ocellated treefrog (Itapotihyla langsdorffii), both species with noxious skin secretions, by black lion tamarins (Leontopithecus chrysopygus). The two predation events took place in Morro do Diabo State Park, an Atlantic Forest reserve in southeastern Brazil. The veined treefrog was removed from a tree hollow by an adult male, whereas the ocellated treefrog was caught on the ground after it jumped from the tree attempting to escape capture. The frogs were completely ingested and no food sharing occurred in either of the events. We did not observe any signs of irritation during the event or when the group was followed in the next day in either of the cases. These are the first reports of lion tamarins ingesting anurans with noxious secretions on the skin.

Abstract
Background: Argenteohyla siemersi (red-spotted Argentina frog) is a
casque-headed tree frog species belonging to the Hylidae family. This
species has a complex combination of anti-predator defense mechanisms that
include a highly lethal skin secretion. However, biochemical composition and
biological effects of this secretion have not yet been studied. Methods: The A. siemersi skin secretion samples were analyzed by mass
spectrometry and chromatographic analysis (MALDI-TOF/MS, RP-HPLC and GC-MS).
Proteins were also studied by SDS-PAGE. Among the biological activities
evaluated, several enzymatic activities (hemolytic, phospholipase
A2, clotting, proteolytic and amidolytic) were assessed.
Furthermore, the cytotoxic activity (cytolysis and fluorescence staining)
was evaluated on myoblasts of the C2C12 cell line. Results: The MALDI-TOF/MS analysis identified polypeptides and proteins in the aqueous
solution of A. siemersi skin secretion. SDS-PAGE revealed
the presence of proteins with molecular masses from 15 to 55 kDa. Steroids,
but no alkaloids or peptides (less than 5 KDa), were detected using mass
spectrometry. Skin secretion revealed the presence of lipids in methanolic
extract, as analyzed by CG-MS. This secretion showed hemolytic and
phospholipase A2 activities, but was devoid of amidolytic,
proteolytic or clotting activities. Moreover, dose-dependent cytotoxicity in
cultured C2C12 myoblasts of the skin secretion was demonstrated.
Morphological analysis, quantification of lactate dehydrogenase release and
fluorescence staining indicated that the cell death triggered by this
secretion involved necrosis. Conclusions: Results presented herein evidence the biochemical composition and biological
effects of A. siemersi skin secretion and contribute to the
knowledge on the defense mechanisms of casque-headed frogs.

Abstract
Bufotenine (1, 5-hydroxy- N,N-dimethyltryptamine) was isolated from seeds of Anadenanthera spp., a tree widespread in the Brazilian cerrado, using an efficient acid-base shakeout protocol. The conversion of bufotenine into N,N-dimethyltryptamine (4) and 5-methoxy- N,N-dimethyltryptamine (5) was accomplished through an innovative and short approach featuring the use of novel bufotenine-aminoborane complex (7). Furthermore, an easy methodology for conversion of bufotenine into 5-hydroxy -N,N,N-trimethyltryptamine (6) was well-established. This is the first study that highlights bufotenine as a resource for the production of N, N-dimethyltryptamines for either pharmacological and toxicological investigations or for synthetic purposes.

Abstract
BACKGROUND Rabies is a fatal zoonotic neglected disease that occurs in more than 150 countries, and kills more than 55.000 people every year. It is caused by an enveloped single stranded RNA virus that affects the central nervous system, through an infection initiated by the muscular nicotinic acetylcholine receptor, according to many authors. Alkaloids, such as acetylcholine, are widespread molecules in nature. They are present in numerous biological fluids, including the skin secretion of many amphibians, in which they act (together with proteins, peptides and steroids) as protection agents against predators and/or microorganisms. Among those amphibians that are rich in alkaloids, there is the genus Rhinella. METHODS Bufotenine was isolated from Rhinela jimi skin secretion after a liquid-liquid partition (H2O:CH2Cl2) and reversed phase high-performance liquid chromatography analyses (RP-HPLC). Bufotenine was also extracted from seeds of Anadenanthera colubrina in acetone solution and purified by RP-HPLC, as well. Structural characterization was performed by mass spectrometry and nuclear magnetic resonance analyses. Cytotoxic tests of bufotenine were performed over baby hamster kidney (BHK-21) cells using MTT test. For the antiviral activity, Rabies virus strain Pasteur vaccine (PV) was used on fluorescence inhibition test and fluorescent foci inhibition test, with both simultaneous and time course treatment of the cells with the virus and bufotenine. RESULTS In the present work we describe the effects of bufotenine, obtained either from toads or plants, that can inhibit the penetration of rabies virus in mammalian cells through an apparent competitive mechanism by the nicotinic acetylcholine receptor. Moreover, this inhibition was dose- and time-dependent, pointing out to a specific mechanism of action. CONCLUSIONS This work do not present or propose bufotenine as a drug for the treatment of rabies due to the hallucinogen and psychotropic effects of the molecule. However, continued studies in the elucidation of the antiviral mechanism of this molecule, may lead to the choice or development of a tryptamine analogue presenting potential clinical use.
