What gets me is we still haven't seen a commercial peptide for a treatable medical condition.
You probably won't for a long time. They will all be sold as prescription meds for a long time when there is legitimate and quality science backing it up to get FDA approval.
This is the reason peptide- and protein-based medicines are expected to take over many pharmaceutical companies portfolios eventually; because there is so much room for new material (along with new targets- ones that cannot be modulated with small molecules) for them to patent or in the case of university research for the school to patent and then license to the pharm company.
I assume that is what you mean by commercial, that it would be available without prescription.
You could technically put the growth hormone releasing hormone analogs in as capable of treating growth hormone deficiency, because some GHRH peptides can be bought online without prescription but there is no official marketing for it or anything like that.
Regarding melanotan, it is not a good drug because there are way too many side effects. If it was worth a shit it would have gotten approved as a drug back in the 80s when it was discovered and they did all the initial tests in AZ.
As for turing machine, just remember the title of the thread is "drugs in the future" so I wouldn't count anything out until we get there.
Lets say for instance I publish a paper this year detailing a new peptide that is no harder to synthesize than melanotan (which has a few quirks with its cyclization but is still easily within grasp of
many online vendors) but has psychedelic activity similar to LSD with less potential for side effects (body strain and 5-HT receptor downregulation) and an equally high potency.
I also dismiss patenting the compound so that it can be sold or traded freely by anyone as soon as I release the information to the public (lets assume I don't have any employment ties either).
You don't think this peptide wouldn't be widely available within weeks?
There are already handfuls of companies that will make and sell any peptide they can. The only reason the market isn't that big is because there are not enough things to sell yet.
The only thing to stop the drug from massive sales would be government legislation.
Even then, if it is that good... better than LSD... people have a way of making things happen and be available because you know the price tag and sheer desire to have it would drive them to it.
