Hi all,
I just came across this paper that has hit the press recently:
http://www.cell.com/cell-reports/pdfExtended/S2211-1247(17)30684-8
As the paper demonstrates, the new small molecule (YKL-06-061) is capable of robustly tanning human skin via topical application within a few days, without any UV required!
Think about it, you slap on an ointment for 5-8 days and without any UV exposure at all, you end up with an even, dark tan that would last for weeks before any new application is required.
The melanogenic effect of the new drug effects the tanning pathway higher up the chemical signalling chain than the melanocortin receptors, by activating Salt-inducible Kinase (SIK) inhibition, thus no nausea or GI symptoms are likely. SIK inhibition is something that is already known to happen in Fitzpatrick skin types III-V in the normal tanning process, so in a way this drug is like a 'genetic switch from' a type I or II skin to or III or IV, depending on how much is applied and for how long.
This is a remarkable breakthrough!
I would like to do some experiments with this compound myself, but I'm guessing the cost for obtaining the chemical will be fairly high in the short term. By my calculation, 5-10 grams would be needed to produce a viable ointment to last a little while (the researchers used a 37.5 mM solution of the 527 g/mol molecular weight substance) Although it's possible that a more diluted version will also work, to match the substance used in the paper, 10 grams of YKL-06-061 would be needed to make a half litre of ointment.
I wondered if there are others on the forum who are interested in clubbing together to purchase a supply?
If there are a few of us we could probably make this work, by buying a 50-100 gram sample.
I am looking into a trade source for YKL-06-061 right now, please PM me if you are interested in being a part of this.
I also wonder if there are any peptide suppliers out there that might be interested in creating a supply chain for YKL-06-061?
