Vincristine/vinblastine extraction from periwinkle help

<< < (2/2)

movies:
Heh, yeah there is an indole in vinblastine, but that wouldn't be the best way to get at indole.  Indoles are so prevalent in natural products that there is a ton of different methods for making substituted indoles.  For starters, I would look into the Fischer, Bischler-Mohlau, Bartoli, and Madelung indole syntheses.

I would imagine that the simplest indole containing compound to get ahold of would be tryptophan.  Seratonin is available over the counter as well, and that's got an indole in it.

Limpet Chicken:
Is serotonin REALLY available OTC (in the UK)?, so I could just walk in to a chemist and ask for serotonin? (no I don't plan on using it on myself LOL)

Or would it have to bee ordered from a supplier? i'm not too sure how suspicious that would bee though, due to it being a precursor, or at least a precursor to precursors of the tryptamines?

Thanks movies, you have been quite a lot of help.

movies:
Seratonin is sold in the US over the counter, I think.  It's just on the shelves in the drug store.

It's sold as a natural anti-depressant.  I don't know if it actually works, but a lot of these herbal things are just hype anyway.

I might be thinking of melatonin, but hey, that's got an indole too.

Limpet Chicken:
Serotonin won't cross the blood-brain barrier, melatonin isn't approved in the UK unfortunately, or I would be buying it by the kilo  ;D
I have other uses for serotonin though, I'm getting a crapload of trichocereus peruvianus soon, and I have heard that a shot of serotonin every few weeks keeps them nice and happy LOL ;D
