IPP/CNRS-A017: A chemical probe for human dihydroorotate dehydrogenase (hDHODH)
Bibliographic record
Abstract
Human Dihydroorotate dehydrogenase, which catalyses de novo pyrimidine biosynthesis, is an emerging target for treatment of infectious diseases, arthritis and cancer. In order to provide a chemical tool studying this key enzyme, we characterized IPP/CNRS-A017, a highly potent, selective, and cell-active inhibitor of the human Dihydroorotate dehydrogenase (hDHODH). In this report, we describe the crystal structure of IPP/CNRS-A017 in complex with hDHODH, providing inside into its binding mode. Additionally, further off-target profiling in a kinome-wide screen and a G-Protein-Coupled Receptors screen as well as investigated cell viability effects in three different cell lines (HEK293T, U2OS, human fibroblasts) confirmed that IPP/CNRS-A017 is a highly selective chemical tool to study the biology of hDHODH. Specific sensitivity to IPP/CNRS-A017 was observed in patient-derived colorectal cancer organoids.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
