@AnthonyA, do these guys look synthetically feasible?

@matteoferla, how does Fragmenstein score these guys? Particular questions:

• The atoms are meant to map directly from hit to design - does your algorithm figure it out?
• The protein conformation down in H61/M165/C145 is quite varied for the different inspirations - if you aren’t already, then you need your heuristic to spot which sidechains move, and include them in the things that move and are tracked. (I think… )

Compound 1 inspiriation fragments are here:

Compound 2 (and 3) come from the nitrile of x0305 (and others):

Sorry, I did not notice there were two submissions.

Okay. I am sorry to say, but your SMILES are wrong. Your heterocycles don’t come out planar. These are aromatic, because you did not specify the Hydrogen or positive charge.

These are minimised, so they work fine:

@mc-robinson, can you update those smiles please.

@AnthonyA, I hadn’t seen until now those minimisations that @matteoferla had run; according to that, these are very happy compounds.
Please let’s discuss how to get them made…

Hi @frankvondelft, @matteoferla, sorry I didn’t see this earlier. This should now be fixed. Just a bit of the reason for why users cannot edit their SMILES directly:

Implementing this is a pain, because once a compound is ordered/made/assayed, we don’t want the identity to change in our system from what was actually ordered/made/assayed. Furthermore, even before that, CDD integration messes up due to the SMILES being different.

I also believe @alphalee said he has routes for these if you want to get them made.
