Which universities is Ceretropic partnering with and what research is being pursued?

We are working with the Barrett Honors College at ASU, offering part time lab positions to honors students. This gives them lab credit, and a place to learn new things, while giving us access to good people. We are spons

Awesome!

The issue with using, in the case of Semax, a D-proline, is that we do not know how that will affect the binding affinities of that side of the peptide. So while it would be less likely to metabolize from that side, sinc

Semax's C-terminus ends with a proline. It's N-terminus is methionine. The standard method to protect the N-terminus is acetylation. No need to change the isomer of the methionine. If you find the studies where they modi

Boom baby: [Behaviourably active ACTH analogues](https://mega.nz/#!AQxCRSjb!cVvrKL8IrkJG3WJMesvhSInI2Um_8NYkEL8RuIWsd00) They replaced the phenylalanine in the sequence with its D-isomer, not the methionine on the N-ter

Roger that!

Can you upload that paper for me, or give me the DOI? I would love to read it. Prolyl endopeptidase is certainly the enzyme that cleaves off the C-terminal end of Semax. That is what the amidation is protecting from. Th

I could see why some would find the stimulation more pronounced with the subcutaneous admin, and the mental "nootropic" effect more pronounced with nasal admin. That could be why some people prefer one route over the oth

Post them here or PM. Doesn't matter to me. That's arachidonic acid Semax. I have known about that for a while. I even tried a couple synths of it a year or so ago. They were not successful with the bulk arachidonic aci

> I'm surprised that it is expensive/difficult as it's a fairly common fatty acid? Yeah, I was surprised too. The bulk AA that we got just would not work in the solid phase peptide synthesis. Not sure why. >What about

Not just that, but it increases the affinity of Semax to its binding sites in the brain. So it's not just about BBB permeability with arachidonic acid.

Yeah, it's getting the arachidonic acid synthesized in large enough amounts, for a cheap enough price, in the form that will work for solid phase peptide synthesis. I have not been able to figure out why the peptide lab

>The production synth AA wasn't made by the same lab correct? Correct, it was a different lab. However, I had the peptide lab test the AA we got, and they said it was correct. So I am not sure. He might have some ideas

No, that was just me using the wrong term. I should have said conformation. The peptide lab we were working with seemed to think it could be made in different conformations, and that is why it was not working in the soli

Yes, I believe solid phase synthesis of AA-Semax involves SN2 reactions, as they are replacing the N-acetyl group with arachidonic acid.

Ok, cool. Let me know what he says.
