Silly Things Large Language Models Do With Molecules

Practical Cheminformatics

Testing Claude’s Molecule Generation Ability To test the molecule generation ability of Claude, a general-purpose LLM from Anthropic, I prompted it to generate analogs for hits from fragment screens. These fragment hits are small molecules with between 11 and 21 heavy atoms.

Tom Lehrer's guide to design of SARS-CoV-3 main protease inhibitors for treatment of COVID-32

Molecular Design

Happy New Year (this orchid opened during night of Dec 31/Jan 1) If we’re designing a SARS-CoV-2 main protease inhibitor to also hit SARS-CoV-3 main protease then it’d be a good idea to engineer it to have greater affinity than necessary for the current target.

Why fragments?

Molecular Design

Paramin panorama Crystallographic fragment screens have been run recently against the main protease (at Diamond ) and the Nsp3 macrodomain (at UCSF and Diamond ) of SARS-Cov-2 and I thought that it might be of interest to take a closer look at why we screen fragments.
