Resynthesis of MMV670652 and separation of enantiomers.

[alintheopen]

MMV670652 was a promising candidate from the briefing document (/data/7353.html) and should be resynthesised and the enantiomers separated by prep HPLC. Will need to find a collaborator to assist with separation.

[PatrickThomson]

The briefing document seems unclear - it reads like they currently have one enantiomer and think the other one might be better? Or was it screened as a racemate? I could potentially have one of my students take this as a project (one's on amide linkers, the other on alcohol linkers).

[mattodd]

If the enantiomers are to be evaluated in Australia, it would be slightly
preferable to make the racemate here too. The options for prep HPLC are:

1. The facility at the University of Queensland (
   http://researchers.uq.edu.au/research-project/9959). This will probably,
   based on past experience, cost money. I can enquire.
2. A separation by Phenomenex (http://www.phenomenex.com/) who have
   previously expressed an interest in the project's open science nature.
3. A separation by Merck, New Jersey, who have also expressed an interest
   in open work and recently made a fantastic job of enantiomer separation for
   Kat Badiola's open catalysis project (data not yet uploaded...)
4. A service based in Europe, perhaps in the UK/Geneva - suggestions
   welcome.

In all cases we'd want to be exploring gratis/in kind contributions rather
than those requiring a fee.

For clarification - MMV670652 was tested as a racemate. It would be beneficial to find a collaborator to separate the enantiomers in order to understand the activity and stability of each enantiomer. Is someone responsible for reaching out to these contacts listed by Mat and inquiring about willingness to help?

[mattodd]

Yes, that's me, but I want to ensure we're not overlooking another source
of separation expertise beyond this current list.

I'll ask around my university about this, or in-case I need to do any separation in future.

Closing before March 2014 meeting (http://malaria.ourexperiment.org/osddmalaria_meeting_/9470) owing to shift in focus away from MMV670652 towards synthetically more tractable MMV669844
