MDMA Neurotoxicity Part 1 Metabolites)

Original post in this thread

MisterYouAreSoDumb · 129 points

This is probably going to be the first in a series of discussions I start about MDMA. There's just too much information for one post. Therefore, I am going to start with one that is very interesting to me: MDMA's metabolites and their role in neurotoxicity. I pre-appologise for the length and terminology used.

_________________________________________________

First off, let's discuss how MDMA is metabolized. The human cytochrome CYP450 is responsible for the metabolism of MDMA. The primary enzyme responsible is CYP2D6, using O-demethylation. This process adds two hydrogen atoms to the two open oxygen atoms in MDMA to create HHMA. Let's look at the structure for a minute.

________________________________________________

MDMA is 3,4-methylenedioxy-N-methylamphetamine

HHMA is 3,4-dihydroxy-N-methylamphetamine

So your CYP2D6 enzyme added two hydrogen atoms to the methylenedioxy structure to create a dihydroxy structure. Once it's been o-demethylated to HHMA, it is no longer active like MDMA is. HHMA can then be 0-methylated further to HMMA, or 4-hydroxy-3-methoxy-N-methylamphetamine. Here is an image to help you visualize this process.

This is…

Sweet, I'm in the same boat, I have a baggie of shrooms in my drug stash, I'm just waiting for a good day to do them. I'm thinking a bluebird day out in the woods around Whistler, should be unreal.

I've only smoked weed, done MDMA twice and K twice, any advice on which drugs I should try next? LSD and shrooms are already lined up so those go without saying.

I like dextroamphetamine for dancing. Plus you can get pharmaceutical grade from someone with a prescription, and not have to worry about purity.

I enjoy Kratom as well. The different strains can be anything from sedating to euphoric.

Salvia is always a crazy trip too! It's strong, but short duration.

Are there any effects of MAOI on Kratom alkaloids?

Bergamottin and naringin(not naringenin) inhibit CYP3A4, which is what metabolizes the active substances in kratom. It has nothing to do with the MAOI characteristics. I drink grapefruit juice with my kratom all the time
