This week's #RDKit blog post shows how to create simple protein--ligand interaction diagrams.
I think there's potential to take this a bit further...

OpenAI just updated ChatGPT to be able to use RDKit, a cheminformatics Python package.

OpenAI's president says this makes ChatGPT "useful for scientific work across health, biology, and chemistry," but it is hilariously still not good at chemistry (🧵)

I will soon be posting a postdoc position in protein biochemistry/biophyics! Interested candidates are welcome to reach out at luclar@kemi.dtu.dk. Experience in protein expression, purification, and assay development is a must. Structural biology would be great! Please RT :)

Rxn-INSIGHT also has some functions for molecules, but many more for reactions. Functional groups and rings are handled separately here:

I will be playing in the O2 Arena!

Well, I won't be playing, I'll be talking... and no, it's not the one in London but the one in Amsterdam...

But if you're around, it would be cool to meet you there. 😊

If you work in drug discovery and you read one thing this weekend, make it this exceptional J Med Chem editorial. Hits on almost every blessed thing I’ve tweetorialized over the last several years.

We had discussed internally some time ago, that the fact, that all SELFIES encode for valid structures might be detrimental to machine learning. A Nature machine intelligence article now seems to confirm this:

Invalid SMILES are beneficial rather than detrimental to chemical language models - Nature Machine Intelligence
Generative models for chemical structures are often trained to create output in the common SMILES notation. Michael Skinnider shows that training models with the goal of avoiding the generation of inc...

This is really driving me crazy: My boss does not want me to leave, I don't want to leave, but still I have to leave at the end of the year, because of the #WissenschaftsZeitvertragsGesetz. So today I reviewed the upcoming job posting for my successor, who should have exactly my qualifications.
