Hi All,
I want to replace the ester structure ('COC(C)=O') with disulfide ('CSSC')

Here is what I did, but it does not work. It seems to need specified
methods to replace the original structure with the new one, not just put
individual SMILES there.

Oh! I didn't realize atom properties were so cleanly integrated into sdfs.
This is great - I will try things out and hopefully it works smoothly.
Thanks a lot!

that there aren't really
other RDKit descriptors that rely on conformers. In the future, I'll be
using QM to generate partial charges as you have suggested.

Hello,
Currently, I am using the method: rdMolAlign.*GetCrippenO3A**()* in RDKit
for comparing two 3D small molecule conformations.
I want to know what is the proper citation for this method?
Is this: Open3DALIGN: an open-source software aimed at unsupervised ligand
alignment

only mentioned rdkit.Chem.Descriptors, could you please explain the key
difference between two packages?
Thanks

oducts and check
that [#X:1] == [#X:2]. With some modifications this also allows you to run
reactions with molecules that require the same R-groups!

Hello,
Recently, I countered such a question.
I can not get the good conformation for a small molecule with
tri-phosphate, like below:
https://www.rcsb.org/ligand/ET9
NC1=NC(=O)c2ncn([C@H]3C[C@H](O)[C@
@H](CO[P](O)(=O)O[P](O)(=O)O[P](O)(O)=O)C3=C)c2N1
The most difficult part I think is that
Thanks a bunch Greg for the very helpful explanation! Things make more
senses now.
