Enhancing drugs chemically (alkaloids)
« on: April 17, 2009, 07:36:57 PM »
Ideas on increasing the potency of drugs chemically.

I will open up with a quote from nbk2000 on Roguesci – in which he makes an interesting referance to some work on the Hive:

The Hive bees have supposedly been dinking around with fluorination of cocaine alkaloids, to greatly increase the potency, 40x or more.

Nicotine is an alkaloid, though a different type, and could perhaps be amiable to such molecular tweaking.

As the lethal dose of nicotine is ~3mg, if you made it 10x more toxic, that'd be .3mg per adult, which is on order of VX. :)


now... Thats what I am getting at. I understand alkaloids are merely bioactive organic compounds. Nicotine is an alkaloid. Cocaine contains alkaloids. Now I also understand Methyl groups are the smallest and fit best through the Blood Brain Barrier. So let me explain...

The first theoretical step would be to Methylate the compound via transesterification – you replace the ethyl, propyl, etc groups with the smaller methyl group. Correct me if another group would work better. In my mind it appears this would make the compound absorb faster, give it lower Molar Weight (which may lower its BP – though I may be mistaken again). This makes it more Bioavailable (or whatever the term is).

Next we flourinate the fuck outta the poor alkaloid. I will presume this means we freebase it and react it with HF or something – or can someone please explain how to do this if I am wrong? Are we flourinating like as if we are nitrating except with F- rather than NO3-? Or are we merely making a flouride salt?

Now we should have the same alkaloid, just far more potent (and toxic) and far more bioavailable.

Dont shoot me for my mistakes – instead correct them!

NOTE: I am NOT a pharmacologist... YET. Teach me and I shall learn fast.

Random fluorination will get you nowhere. The molecule has to fit in its receptor like a like a key in a  lock.  Fluoro groups themselves do not give the molecule more affinity for its receptor, unless they make the molecule fit better. They can help in certain situations for other reasons, such as preventing metabolism.

*cringes* Did I REALLY imply random flourination? Oh yes... I kinda did. Well if we work out where to put the flouride radicals we could model some pretty nice things. Naturally, me being the type of guy I am... I want more toxic potency and a lower LD50 for a easy modification. I was hoping we could add flourine into Atropine to make a servicable toxin of it.

Fear not, I am reading my books like a maniac and will come back better educated.

"As the lethal dose of nicotine is ~3mg"

Isn't it more like at least in the 50mg range?

They are probably talking about the cocaine analogue that can be up to 10x as potent as cocaine itself and is made from 4-florubenzoic acid and some tropinone like substance, which can be formed from the hydrolysis of atropine and other alkaloids found in datura, and other related species.

Yeh 50mg is the LD50, Its 3mg for mice that may be the information hes talking about.
There once were some bees and you took all there stuff!

Though not totally on topic, this page might interest a few.. http://www.seanmichaelragan.com/html/%5B2008-09-10%5D_Cocaine_analog_in_two_steps_from_native_plant_material.shtml

I wonder if there is an easier way? Its not like the yucky tropane alkaloids are hard to get.

Vesp, Thanks for the link. I am considering doing that method, albeit small scale. Will review again later today.

Does anyone understand why DEAD (diethylazodicarboxylate) is needed? Seems like something useful could also form with out it, maybe the hydrogen can just be completely taken off?

Forgot about this thread, so I will post a quick update: I am still figuring out the receptor thing, but soon may have a program to do the computation for me - a pharmacology guy in the uni has become a good mate. I will make it public available
