Thank you for the time to explaining this.

Regarding yohimbine from the other thread, we could say that it is a sort of a tryptamine based stimulant? It has an indole, but do not know if the locked amine in that side position classifies to be considered as tryptamine. From what I could read it has a lot of activity both as an agonist and antagonist on a numerous types of serotonin receptors.

yohimbine does have the indole ring group as part of its structure however i dont know the pharmacological significance of that

i also dont know much about yohimbines properties in the body other than that it is a alpha2-adrenergic antagonist, and that it causes peripheral vasodilation

i still have some 5-methoxytryptamine, 5-methoxytryptophol, oxindole etc in my lab. i tried these and didnt have what i recall as good experience

As I understand it, only the 5-methoxytryptamine is an actual tryptamine. I never heard about the other two compounds. Alexander Shulgin wrote a really interesting book about tryptamines, called Tihkal. Many of the compounds are not legal, but the most interesting is his discussions about the structural differences and their impact on bioavailability and activity.

From what I could understand the definition of an tryptamine family of compounds is a molecular structure where the amine is attached to an indole with an ethyl chain, that is 3-(2-aminoethyl)indole. If we take the LSD as an example it also have the aminoethyl chain locked in a ring structure, however pointing “up” from the indole base. And what I know it is considered to belong to tryptamine family. Most of the other tryptamines I have seen usually have freely rotating aminoethyl chain. Therefore I am not fully sure if a compound with aminoethyl chain locked on the side is a part of the tryptamine family. Not that it really matters.

About yohimbine’s activity in the brain, according to wiki, it does affect a lot of different 5-HT receptors. Also in the description about Serotonin receptors also in wiki, is a nice overview table with the various receptors, stating its specific functions together with examples of agonists and antagonists. The yohimbine does appears in numerous placeless. That yohimbine have a strong activity on serotonin receptors would also explain the side effects that many (including you) experience.

But what do I know, as I said previously organic chemistry is more of a very fun and interesting hobby of mine.

i am no expert on neurobiology neurochemistry etc. I rely on looking these things up because i dont spend much time dealing with them. I did more years back

No problem, I was just curious about your point of view, due to your years of experience.
