Breaking C-F bonds in drugs – metabolism mediated release of fluorine By Samuel Coe and Julia Shanu-Wilson Lenacapavir, recently approved for multi-drug resistant HIV-1 infection, contains 10 fluorine atoms. Increasingly used in drug design, some drug structures are now bristling with fluorine atoms.

“AI will not replace drug discovery scientists, but drug discovery scientists who use AI will replace those who don’t” – comment during EFMC meeting 2018 Progressing a drug molecule from concept to commercialisation typically takes 10-15 years and has high associated costs of up to $2 billion per launched drug, if all failures are factored in.

Most papers describing new methods for machine learning (ML) in drug discovery report some sort of benchmark comparing their algorithm and/or molecular representation with the current state of the art. I wrote more about the problems with this dataset in a Practical Cheminformatics post in 2018. We want to design drugs that are safe.

2 Figure 1 Not only does the carboxylic acid moiety of the infamous drug zomepirac undergo conjugation to an unstable acyl glucuronide, the pyrrole undergoes oxidative metabolism to an epoxide intermediate that can be trapped by glutathione (Figure 2). 2a Figure 2 Also reported are more complex “per-oxidative” oxidations.
