Alchemica Posted February 25 Share Posted February 25 Warning: due to the overly toxic nature of potential alkaloids found in this family, self-experimentation is NOT RECOMMENDED. This information is presented for interest's sake only Triandrus Narcissus - N. triandrus cultivars eg cv. 'Hawera' Many of the Triandrus Narcissus are not yet phytochemically characterised. Many of these Narcissus have some potential to biosynthesise pharmacologically relevant concentrations of Amaryllidaceae alkaloids of the non-Sceletium-type class, which can be of significant potential toxicity eg lycorine, or potent additional pharmacological action eg galantamine, it seems it may be potentially possible to potentially utilise them as exclusive sources of mesembrine-type alkaloids and interestingly, utilise even renewable aerial parts of the plant, instead of bulb material. Some of the N. triandrus hybrids have been directly used for their mesembrine-alkaloid pharmacological alkaloid profile in animal studies [1] Quote "The aerial parts of Narcissus triandrus were extracted with methanol in a Soxhlet apparatus. The basic extracts were purified by column chromatography with silica gel as adsorbent. Three mesembrine-type of alkaloids were identified: mesembrine (1), mesembrenol (2) and mesembrenone (3), this last one in a very small amount. All were characterized on the basis of their spectroscopic properties. However, none of the previously described alkaloids [such as haemanthamine, lycorenin, lycorin, homolycorin, galanthamin and tazetin] were found." [2] Narcissus pallidulus, pictured above, contrary to N. triandrus cv. 'Hawera' [which seems like it has the ability to biosynthesise lots of other toxic stuff in it] has an alkaloid profile of 139.9 μg/100 mg−1 DW mesembrine-type alkaloids, mesembrenone 71.0 μg/100 mg−1. Never seen bulbs around myself in Australia. In vitro alkaloid production has been found to be viable: In vitro propagation and biosynthesis of Sceletium-type alkaloids in Narcissus pallidulus and Narcissus cv. Hawera The alkaloid profiles of different Narcissus are discussed in Alkaloid Profile of Fifteen Different Species of Narcissus L. (Amaryllidoideae) Collected in Spain Alkaloid profile of N. pallidulus showing near exclusivity of mesembrine-type Sceletium alkaloid biosynthesis [doi:10.3390/plants14172793].

Breizh Posted February 28 Share Posted February 28 (edited) Alongside the mesembrine-type alkaloids there's one named Roserine which - despite appearances, is cyclized mescaline which makes it an isoquinoline... with some indole-esque elements: Here's a paper discussing it's structure.

Alchemica Posted March 1 Author Share Posted March 1 (edited) Welcome Breizh, thanks for the reply. With roserine, it's fully quaternary at the nitrogen and I doubt it would have much classical 5-HT2 mediated effects. Possibly in line with berberine and all that with some sort of modulatory action but pharmacokinetics might be poor, added with poor BBB penetration etc. The tetrahydroisoquinoline variant might have better CNS activity So many of the tetrahydroprotoberberines and related alkaloids have interesting PEA scaffolds in them but generally lose more classical psychedelic PEA activity, developing things more like D1/D2/5-HT1A/adrenergic activity, sometimes with some 5-HT2 modulation. Glaucine, as an aporphine, stands out as one of the enantiomers has positive allosteric modulation of 5-HT2ARs Pukateine is interesting as a dopaminergic agent with a MDPEA moiety And as a MDPEA/AMPH-like hybrid, anonaine seems initially interesting but: Interestingly, despite relatively potent DAT inhibition, the longer-term net effect of (-)-anonaine on dopamine seems to be decreased dopamine content, potentially via interfering with dopamine biosynthesis via tyrosine hydroxylase. This may be why, contrary to psychostimulant effects, the more traditional use of plants containing (-)-anonaine does not seem to reflect those expected in the case of more typical dopamine transporter inhibition.

Another quaternary amine is dehydrobufotenine which is reported to be active - when appropriately prepared.

Sassafrass contains a few of these alkaloids including Cinnamolaurine which is reported to be very enjoyable. That's 2 phenethylamine structures, including amphetamine! It could theoretically be made from Higenamine. Edited March 1 by Breizh Quote Link to comment Share on other sites More sharing options...

This is detailed on the herbpedia wiki. These quaternary alkaloids can also seem to often lack appreciable 5-HT2A affinity whilst having novel actions like 5-HT3/nAChR effects, more in line with producing toxidromes of neuromuscular junction blockade/paralysis type peripheral effects, for example in quaternary tryptamines: Quote Pharmacological studies have demonstrated that 4-HO-TMT and bufotenidine differ in their affinity for 5HT2a and 5HT3 receptors. Bufotenidine is a selective 5HT3 agonist, where 4-HO-TMT lacks this activity while displaying weak agonist activity at the 5HT2a receptor (Chadeayne et al., 2020; Glatfelter et al., 2022). Potentially of more relevance to WLP [Wood-lover's paralysis] and yet to be determined is whether 4-HO-TMT or possibly an oxidation product thereof displays the same anti-nicotinic effects at the neuromuscular junction as bufotenidine. Bufotenidine has been found to produce significant neuromuscular junction block and flaccid paralysis owing to an anticholinergic effect at muscle type nicotinic receptors https://doi.org/10.1016/j.toxicon.2025.108450 4-phenyl-tetrahydroisoquinolines are interesting - primarily as monoamine reptake inhibitors eg triple DAT/NET/SERT binding - and very simply synthesised from the respective phenylethanolamines Whilst not a natural product and annoying as the synthesis involves extremely watched synthetic routes, this 2,3-benzodiazepine scaffold is interesting in producing things like potent DAT inhibitors from well-known CNS active pharmacophores https://en.wikipedia.org/wiki/GYKI_52895 Quote Link to comment Share on other sites More sharing options...

It could theoretically be made from Higenamine. I'd be SUPER cautious with the family initially - the 1-benzyltetrahydroisoquinolines are known Parkinson's inducing neurotoxins. They might initially feel 'good' as I'm pretty sure 1-Bn-THQ induced substantial dopamine release acutely but it's what's after that that may be scary? https://doi.org/10.1046/j.1471-4159.1995.65062633.x This is a hybrid of two known neurotoxic compounds - salsolinol and 1-Bn-THQ Edited March 2 by Alchemica 1 Quote Link to comment Share on other sites More sharing options...
