Here's a free MIT introductory chemistry course.
You have all the lecture notes available, the only thing unavailable is the actual reading, which you can substitute by just reading more on what they cover in the notes on wikipedia or something.
You can pick and choose which topics you want to learn about as well.

I think you're out of touch with what the market wants.

It's just a minor incision, you press the needle or blade into the eye and collect a blood sample. SIMPLE! Even a lazy stoner couldn't fuck it up. And then they know how high they are.

I was thinking of making a stoner scale. Like snoop dog heads. Half a snoop dog means you're buzzin. Five snoop dogs means the rooms spinning.

You'll have to make them disposable though so they aren't sharing needles with their friends tho.

Wouldnt this be impossible to use this as a scale? For myself, I cant recognize the redness always having much to do with how high I am. It depends on so many things, and also sometimes when you dont have red eyes, you look in the mirror and you do!

Things like are you already tired but trying to keep awake? That puts strain on the eye. Theres too much light where you are at to your high eyes. Sometimes I get red eyes just going outside with barely any wind. Id say the giveaway factor to it is the fogginess of the eyes.

Maybe find out what exactly gives you red eyes, in depth. Because most of the time you dont get red eyes.

They've already discovered how to gauge metabolites of THC which enter the bloodstream immediately after use. IDR offhand, but there's a specific one which is not psychoactive and is a telltale sign of recent use (versus traditional tests which use residues that last for weeks or months, in rare cases).

You can't really rely on symptoms of use as a metric, because cannabis is SO varied in its effect/cannabinoid composition. One of the reasons I don't like many dab batches is because the extraction methodology often excludes non-volatile components which alter the chemical nature of the cannabinoids, so sub-professional-grade dabs are no "clean slate" for comparison either.

Hello, /chem/!
I was wondering about this route to phenylacetic acid, and couldn't find it on the internet. Would the following synth work?

>Benzene is reacted with chloroacetic acid in the presence of aluminium chloride catalyst to yield phenylacetic acid. Would the aromatic ring attack the chlorinated position of the acid or the carboxylic one?

Thanks guys!!

Actually, I'm NOT willing to make P2P. I'm willing to make MDP2P, and as such, I woudn't be performing the above reaction with benzene, but with methylenedioxybenzene. So I was also wondering whether or not the AlCl3 would be a problem for the methylenedioxy ring. Would it be demethylenated by this catalyst? If so, I could perform the alkylation with chloroacetic acid before performing the methylenation of pyrocatechol with H2CI2 or H2CSO4. Problem is, in this case I imagine that the phenolic -OH groups would attack the chloroacetic acid instead of the aromatic ring doing the nucleophilic attack.

Any input on the above?
Thanks again!

Actually, I'm reflecting on this again.

I'm at non-chem related job right now so I don't have access to chemdrawzzz. But my current understanding of aluminium halide catalysed de-o-methylation forms that weird negative aluminium anion complex with the MeO (much like in F-C alkylation). Then a bound halide should attack the methyl group spawning the leaving MeX (MeCl) and generating that as a gas (like all o-demethylations do). Then you can hydrolyse the system to generate the phenol.
It also doesn't seem to be a catalysis as AlCl3 is reacted away.

Reflecting on it further, I don't see why it wouldn't happen, albeit very slowly. I think it wouldn't be worth it since it should exist in equilibrium with the product <-> reagent when it even is demethylated because the chloro-alkane formed would immediately react with the hydroxide to reform the methine-dioxy-benzene.

I'm confident enough in that answer and will revisit when I have more time during the day.

What Bombastus said here. The Dioxy-methine bridge is generally pretty stable due to conjugation. See if you can find a table of pKa for the leaving groups and compare if you aren't confident.

Yupp. Looking at it again, my instincts agree with the methine/methylene bridge being stable. Even if it were to break, the OH- and Cl- should immediately react away to reform alumina and chloride ions (HCl should not be created due to it being too unstable to simply be formed in this reaction).
If you could make HCl this way, let me know. It'd be interesting to follow up on. But my guess is no.

>"Anydrous AlCl3 is a relatively strong Lewis acid. It bonds with the lone pairs of electrons on the oxygens in the ethers. When this complex is hydrolyzed, the ether is cleaved. When you do this to safrole, you can definately expect a mess, since the methylenedioxy ring gets cleaved, and things can get even more out of hand from there. In the case of eugenol, this cleavage is exactly what we're looking for."

You are ignoring rates man. These things typical occur at much slower rates than they are now, which implies something must be causing upsetting the balance and tilting the equilibrium in some way.

Even you have to admit that a reasonable logical deduction is that we are the cause. If CO2 is considered a major factor, and CO2 normally cycles yet is experiencing a dramatically increased rate of buildup, wouldn't it not be that far fetched that some sort of force is behind the acceleration? And since we do produce metric shit-tons of CO2, is it really that far-fetched that we are not the cause?

Does anyone know why loperamide is so easily expelled after it has crossed the BBB when compared to, say, morphine or fentanyl? I vaguely remember reading somewhere that it was because of the chlorine atom, but that could be totally wrong.

I know that the diacetylation of morphine into heroin facilitates its crossing the BBB by making the molecule more nonpolar, but that doesn't explain why it isn't expelled by the P-glycoprotein.

I have a few links, and I've read the majority of them. The third one says removing electronegative atoms should decrease the efflux, so it seems that removing the chlorine would help.


Pic related. I don't want to be 'that guy' who wants to acetylate everything because that's what works for heroin, but if it works then it works. What other changes to the molecule might make this drug more recreational?

I'm not entirely sure, but do consider that heroin itself is just a prodrug for morphine. By that I mean heroin itself does not cause the affects but deacetylation of said molecule can then generate the affects.
I think 6-monoacetylmorphine has some effects, with 3-MAM not really producing much, and straight morphine having the most affect.

My point being that perhaps heroin can rapidly cross the BBB, both into and out of the brain, but a higher concentration of deacetylating enzymes inside the BBB that sort of "trap" the resulting morphine in the brain. My research advisor jokingly refers to the BBB as the Brain-Blood Barrier because we tend to forget it stops things from leaving the brain, too.

Purely conjecture/speculation, but perhaps Lope is not able to be chemically modified such that it can be trapped within the brain. Adding functional groups wouldn't necessarily remedy this, since the base molecule is already quite permeable?

Why do you think no one has tried to grow their own coca/poppies indoors? Just surprised since weed and shrooms have been cultivated indoors for quite a while now. Granted processing cocaine and (probably) heroine takes more work but still, hydroponics have become complex. So, I would reason that drug extraction from other plants doesn't seem too difficult for some of the more curious in the age of the internet.

I wouldn't know much about the l-tyrosine. As far as I know, the only thing that has been shown to noticeably increase alkaloid content is carbon dioxide.

Nice to be here Bombastus. They sell bulk tyrosine as a supplement, and it's used at a rate of 2mol tyrosine/1mol morphine in the biosynthetic pathway of the opium poppy, so I definitely get the feeling that if it can be reasonably absorbed by the plants then it should increase the alkaloid content. Maybe I'll do a little unofficial test with a few plants. Nothing huge, but if the chance arises then I'll see what I can do.

if i didn't fucking hate fucking botany with a fucking wrath, then i'd probably go around growing poppy plants and analysing the difference in morphine. you could always do that and report back?
i'm sure a lot of people would be quite greatfull for that. but my guesses (with my limited understanding of biosynthesis) is that just because you have a precursor doesn't mean you will get more end product

the complex pathway you posted up probably has a limiting reaction that isn't just the starting precursor. this is just me speaking for a statistical point of view. it could very well increase morphine production but i don't think it's likely

This, 1000X
enzyme kinetics are tricky because in a test tube you can force a reaction with high concentrations of substrate, but often enzymes are highly regulated, including inhibition by the products of the reaction or biosynthetic pathway.

Simple equilibrium dynamics and mass action, that sort of thing, doesn't really apply to biosynthetic pathways. It's worth a try though.

It would be impossible to get an exact number, but it would be only difficult to generate a reasonable approximation. It comes down to a matter of how many orders of magnitude off you might be.

I'm not into this evolutionary stuff, so I don't know the numbers BUT apparently there's 3.5 billion years between us and the first cell. Assume 1 hour generation time until 610 million years ago when multicellular organisms appear. Let's move on to a 10 hour generation time. Animals popped up pretty soon, so 600 million years ago the generation time jumped to 10 days. 500 million years ago things crawled on the land with, say, a 1 month generation time. Around 360 million years ago amphibians appears so let's go with a 6 month generation time for a seasonal sorta thing goin on. 150 million years ago amniotes appeared, so let's finally reach a 1 year generation. Mammals 130 million years, so jump up to 2 years. Homininae 10 million years ago; big jump to 15 years. Modern humans 250,000 years so 20 years.

Despite my pulling this out of my ass/wikipedia, let's do a tally:

1 hour generation time: 2.89 billion years * 8760 hours per year *1 gen/hr = 25.3 trillion generations
10 hour generation time: 10 million years * 8760 hours per year * 1 gen/10 hrs = 8.76 billion generations
10 day generation time: 100 million yr * 365 day/yr * 1gen/10day = 3.65 billion generations
1 month generation time: 140 million yr * 12 month/yr * 1 gen/month = 1.68 billion generations
6 mo. gen time: 210 million yr * 12mo./yr * 1 gen/6mo = 0.42 billion gen
1 yr gen time: 20 million yr = 20 million gen
2 yr gen time: 120 million yr = 60 million gen
15 yr gen time: 975000 yr = 650000 gen

Nobody has any chance of doing that without access to a full lab, chiral resolution techniques, it has 5 chiral centers FFS, 32 potential isomers, fuck that.

If you can synthesize that, you might as well just make a fuck ton of LSD or a synthetic opiate like a fentanyl derivative because you are a fucking amazing chemist and apparently, very well equipped for organic synthesis.

Its already synthesized for you in kratom, its much easier to design an extraction to isolate the active/actives from kratom than it is to synthesize kratom from serotonin.

thankyou, thankyou, thankyou!

The report is on the human aspects of successful treatment in terms of subsequent relapse, so i hadn't geared my head to think about it in terms of organisms other than humans

I am sorry, it's been a long day and i'm pretty beat. I'll brain harder from here on

So, during my lab's standard dansylation protocol (for wheat, in this case) , I have found that the colors in each microtube vary. I don't know if this is because each tube contains a different genotype of wheat, or if the process isn't thorough enough to get the dansyl chloride mixed up in the tube to produce more yellow color. I don't know if that will have an effect on the results when I run the samples through HPLC at the end, but thought I'd ask.
