      psychoactives acetylation     

Hi !!! dear bees !

we know that  the acetylation of morphine gives heroin (diacetylmorphine), which is more potent (2times) .

so, have 2 questions :
     Will acetylation of other substances (uppers or downers) could increase their potency ?

  1) CAN WE MAKE "acetyl-mdma",  "acetyl-dxm",  "acetyl-caffeine"(!!!),  "acetyl-thc!"  "acetyl-amphetamine",(or acetyl-ephedrine)  "acetyl-methcat",  "acetyl-diazepam"............
 
  2) IS ACETYL-CODEINE ACTIVE ? ( and If yes ,by nasal ,i.v. , or smoked administration?)

any comment about pharmacology of acetylated compounds will be VERY  much greatly appreciated

No - it is a lot more complicated than that - most of the compound you mention would be inactive.

You can acetylate THC, which will give you Tetrahydrocannabinol Acetate (THCA). It is about double the potency of THC. Converting the THC to its high rotating form beforehand will increase the potency even more. Salvinorin can also be acetylated, but that would be the epitome of overkill. wink

      You can't acetylate salvinorin A and DXM.     

You can't acetylate salvinorin A and DXM. As far as I remember the stated higher potency of O-acetyl-THC has been questioned, and IMHO there wouldn't be any reson for a higher potency.

The acetyl group on alcohol groups ("O-acetyl") makes compounds more lipophilic so that they can more easily penetrate the blood-brain barrier. Since the acetyl group is easily split off by ubiquitous esterases in the body the compound (e.g. morphine) is regenerated and can act in the brain. Nothing mysterious smile.

(With these keywords you should be able to search the web (e.g. http://en.wikipedia.org/) or biochem / pharmacology books smile)

      i'd like to know why opioids, dxm n thc can be     

i'd like to know why opioids, dxm n thc can be acetylated (i heard alcohol group on dxm).
And  I'd like to know why acetylation of compounds as (ephedrine,PEAs,mdma,benzos, tryptamines)... gives inactives products.

Is there a rule that tell us the products that can be acetylated and the others that can not be acetylated ?

My second question is : does acetylcodeine can be snorted or smoked, and is acetylcodeine potent ?

      Get yourself a chemistry schoolbook     

Is there a rule that tell us the products that can be acetylated and the others that can not be acetylated ?

This question is simply too general and you can only understand the answer if you pick up a basic organic chemistry schoolbook and learn the basics. Just waiting for someone to bother explaining will not accomplish anything.
Anyway, only the nucleophylic groups can be acetylated, but they must be able to eliminate a proton to form a neutral product. Thus, for example, groups like: -OH, -NH2, -NHR, -SH, heterocyclic =NH (like in indole) and active methylene groups. Therefore alcohols, phenoles, amines, anilines, malonic esters, indoles, pyrroles and other similar heterocycles. But in general you can also call acetylation any electrophylic substitution on the aromatic ring that substitutes -H with -CO-Me.

      Acetylcodeine     

Read this Post 478260 (Vitus_Verdegast: "Found these:", General Discourse). Or UTFSE for "acetylcodeine". Shortly, 6-acetylcodeine is a convulsant (I really don`t like this 3-O-Me thing - personal experience).

      why     

excuse me for my poor knowledge in chemistry,
But as Nicodem told : "groups like: -OH, -NH2, -NHR, -SH, heterocyclic =NH"... ,

Then, i think we could acetylate the NH2 of GABA(to make it cross the BBB)
, or acetylate the OH of ephedrine, amphetamine,  cathinone... to have a more potent coumpound (or active at least).

Sure, you can acetylate amino groups to get amides, but they are not split off in the brain, so you are left with an inactive compound in your brain. And now go, study your books smile

I remember reading a journal article on Salvinorin acetylation or something of that nature. I think it was in JACS and I forget the results. If I had the kind of library access I use to have I would search for this article and post it here.

      help     

diacetylmorphine which has a "MeCOO" group instead of morphine which has a "OH" group is metabolised into morphine in the brain.

gaba has too an OH group which makes it acetylable to cross the bbb, then tha brain converts acetylgaba to gaba.
it leave us with a more potent drug(perhaps sniffable or smokable).

Could anyone tell me where i am wrong ?
 
PS : does anybody know what compound change diam to morphine in the brain?

      Wrong&Wrong

You are wrong about many things, but first I will give you two advices:
1.) You should learn at least basic pharmacology. The knowledge you show is near to zero and yet you give bold claims and propositions.
2.) Same as advice #1 but change the word "pharmacology" to "chemistry".

If you could acetylate the -OH of a carboxylic acid like GABA you would get a mixed acid anhydride which gets hydrolyzed by water way sooner than being transported to the brains (luckily). That is, if something like O-acetyl-GABA could ever exist, which it does not as it would immediately cyclise to pyrrolidone.

PS : does anybody know what compound change diam to morphine in the brain?

One or more of the numerous esterase enzymes, I would guess.

      i heard one time...     

i was told it was the Fe(iron) and heat that converted the diacetyl to morphine. my chemistry skills are limited. i may bee full of shit. please correct me, but i cant find the info source outta google.tongue
