This was surprising given that replacement of a phenyl with a pyrimidine and fluorination of aryl or heteroaryl rings are techniques often used to increase metabolic stability.

“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.

To curb glucuronidation at that position a gem-dimethyl group was incorporated which not only boosted metabolic stability, but also resulted in increased potency of the final lead compound.

I wrote more about the problems with this dataset in a Practical Cheminformatics post in 2018. Initially, I would recommend aqueous solubility, membrane permeability, in vitro metabolic stability, and biochemical assays. I have a few ideas. Focus benchmarking efforts on simple, robust, relevant, clearly defined endpoints.
