amazing this one, but i hate that name

[Ambrisentan]

Chemical structure template from the atypical antipsychotic Piperazine, then added some ligants from Fluoxetine, Methylphenidate and Phenmetrazine.

^^ LOL ! Looks like brain poison to me.

That structure has six chiral centres and so could be any one of 64 different molecules. You need to think in 3D. Drugs are not 2D entities. Linking an aromatic to a morpholine ring at the N also means that it will adopt a minimal-energy conformation and that will depend on two of the chiral centers so you might end up with about 96 conformations.

Look at drugs like Taxol. It is made synthetically but the yield is something like 3%.

 

[MedicinalUser247]

WOW ! Taxol's a big Molecule. I wonder who designed it.

Germans

Yes, but what German ?

 

[Mjäll]

Yes, but what German ?

Just kidding, it's okay because we're in a fluff thread

Germans are hilarious, we even have them on bluelight

Do you know what people have the most infectious diseases? Germans

Do you know where mermans live? Mermany

Thanks. Where can I learn more about this subject so I can make better molecules?

Above I've posted a link to 'Vogel's Textbook of Practical Organic Chemistry' which is dull but important. If you can't actually make the stuff, nobody can ever conclusively state what it's activity will be.

Download ChemSketch, it's free. You can draw something and in Tools-->Generate-->SMILES Notation it will give you a SMILES (Simplified Molecular Input Line Entry Specification) string that defined the chemical.

Just paste it into the search bar of:

https://pubchem.ncbi.nlm.nih.gov

And if it's already been made, it will give you all of the references. But more powerful, if you just draw PART of the structure and give it that, it will show you all of the known compounds that contain the sub-structure you drew.

So start with something simple like amphetamine and see the hundreds of compounds that have the amphetamine scaffold within them.

It takes a few days of practice but I can draw and check something in about a minute. At the end of that minute I might have anything from 1 to 10000 references. Then read them. That's the boring bit, but like anything else, drug design is1% inspiration and 99% perspiration.

I believe PubMed gives you the pKa, LogP and other important physical data. Almost all psychoactive drugs have a LogP between 1 & 5. Maybe 5.5 at a push. But above that they won't cross the BBB (blood-brain barrier) unless their is an active transport... and those are quite rare.

Looks like a lignan if I squint my eyes. That vinyl ether is sussy.

That looks like a little lizard dude. Or a synthetic estrogen.

 

[AlsoTapered]

Vinyl ethers are a little more stable than I expected, but a quick search only shows things like divinyl ether (inhalational anesthetic).

Thanks for checking.
