The Open Source TB account has been a little quiet of late but what a great post to make our comeback with! Carlota is working on the diversity-oriented synthesis portion of #OSTBSeries4, which you can read more about here: github.com/OpenSourceTB/O…

So excited to have a new honours student join the Rutledge group - Carlota has just started working on the @OpenSourceTB project with me!

And hopefully we'll be back at it soon, just with a bit of extra PPE 😷 👩‍🔬

COVID-19 restrictions have kept us out of the lab, so unfortunately we don't have any more current synthetic work to discuss right now. But that doesn't stop you from getting involved - #OpenSourceDrugDiscovery projects are larger than a single lab!

@Inorganick_ We're already using lots of base (like 5 equivalents per amine!) but will definitely try heating it up and see how that goes

English

Dr Nick Butler@Inorganick_·20 Eki

@OpenSourceTB Increasing the temperature is probably a good idea. It sounds like the first allyl group is going on easily enough, but the second one needs a bit of encouragement. You could also bump up the equivalents of base/electrophile if you haven't tried that yet.

#OpenSourceTB's diversity oriented synthesis also includes a double allylation of boc-protected linear polyamine (analogous to the propargylation we mentioned last week). Theoretically, this will help us install other functionalities...

We’ve tried THF instead of DMF, + different bases (KOH and NaOH) but our yields are still low..,we think we’re getting the mono-allylated side product, which complicates purification. Any ideas? We’d love suggestions! #ChemTwitter #RealTimeChem #MedChem #OpenSourceTB

This fab illustration of the 6 laws of #OpenSourceDrugDiscovery features our sister project @O_S_M but the same principles apply to our work, too! If you're curious about them, read the paper here: doi.org/10.1002/cmdc.2… #OpenScience

…but we struggled to purify the product of the Michaelis-Arbuzov reaction. We tried a column (DCM:MeOH with 10% NH4) + trituration with toluene, then lockdown interfered. Have you got any ideas for purifying this? We’d love to hear! #ChemTwitter #RealTimeChem #MedChem

Series 4 of #OpenSourceTB has a focus on diversity-oriented synthesis. Here’s one of the routes we planned to install a non-activated alkene. Our first reaction (acylation) had great yields… #MedChem #ChemTwitter #OpenSourceDrugDiscovery #OpenScience

Curious about what success #OpenSourceDrugDiscovery has had so far? Well, the easiest one to point to is the identification of a new resolution approach for #Praziquantel (used to treat schistosomiasis). doi.org/10.1371/journa… | @MatToddChem @PLOSNTDs

#OpenSourceDrugDiscovery aims to accelerate that process by sharing ideas and data openly, and encouraging collaboration. We're hopeful that these #OpenScience principles will help us finding new drugs to treat #Tuberculosis and thus save millions of lives!

**EDIT - this reaction scheme has a rather important component missing - we've been using NaH + dry DMF, with the propargyl bromide (based on a previous student's work with allylation).

English

Open Source TB@OpenSourceTB·12 Eki

We're struggling to isolate pure product - we think partially bc the reaction mixture contains both mono- and bis-propargylated amine. Read about our attempts (and make suggestions!) here: github.com/KlementineJBS/… Any ideas #ChemTwitter? #RealTimeChem #MedChem #OpenSourceTB

English

Open Source TB@OpenSourceTB·12 Eki

We started trying to use boc-protection to make some bis-functionalised linear polyamines - the plan was to propargylate the protected amine then use a naphthyl-azide coupling partner for a click reaction. #RealTimeChem #OpenSourceTB #ChemTwitter #MedChem #DrugDiscovery

English

Open Source TB@OpenSourceTB·12 Eki

@Inorganick_ Omg - just realised that I've forgotten to include NaH on the reaction. I've tried using it but had no luck with it, possibly bc the tin we have is pretty old. Will definitely try cesium carbonate though!

English

Dr Nick Butler@Inorganick_·12 Eki

@OpenSourceTB Cesium carbonate is a great base to use for propargylations if you have it handy. If your DMF is dry, you could always try NaH too, but that's probably overkill.
