Noncovalent Protein Arginine Deiminase (PAD) Inhibitors Are Efficacious in Animal Models of Multiple Sclerosis
Bibliographic record
Abstract
Peptidyl arginine deiminases have been shown to be hyperactive in neurodegenerative diseases including multiple sclerosis. An α-amino acid-based core structure, derived from a hydantoin core, with unique heterocycles on the side chains were synthesized as potential noncovalent inhibitors of PAD enzymes. Among the various heterocycles investigated, compound 23, carrying an imidazole moiety, exhibited the highest potency in this series with some selectivity for PAD2, and was further investigated in vivo. Pharmacokinetics in mice suggested the C max to be 12.0 ± 2.5 μg/mL and 170 ± 10 ng/mL in the serum and brain, respectively, when compound 23 was administered at 50 mg/kg via single dose ip. At the same dose, compound 23 also reversed physical disability and cleared the brain of T-cell infiltration in an EAE mouse model of multiple sclerosis (MS). This novel series of compounds show promise for further development as disease modifying agents for the potential treatment of MS.

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.
