Abstract
Phosphodiesterase-4 isoenzymes have absolute specificity for cyclic adenosine-3',5'-monophosphate and are considered potential therapeutic targets for the treatment of chronic inflammatory disorders, such as chronic obstructive pulmonary disease, with small-molecule inhibitors. Several selective phosphodiesterase-4 inhibitors are in clinical trials of chronic obstructive pulmonary disease, including cilomilast and roflumilast. Despite some encouraging data from phase III clinical trials, the current generation of phosphodiesterase-4 inhibitors is hampered by a low therapeutic ratio. Indeed, a major obstacle is their propensity to evoke non-steroid-like side effects, of which nausea, diarrhea, abdominal pain, vomiting, and dyspepsia are the most common. In addition, a particularly worrying potential toxicity of phosphodiesterase-4 inhibitors, also shared by phosphodiesterase-3 inhibitors and other vasodilators, is arteritis/periarteritis. One potential means of improving the therapeutic ratio and safety of phosphodiesterase-4 inhibitors may lie in the development of compounds that have broader phosphodiesterase specificity. Of the 11 phosphodiesterase families that have been unequivocally identified, dual-specificity compounds that inhibit phosphodiesterase-4 and phosphodiesterase-1, phosphodiesterase-3, or phosphodiesterase-7 may offer the best opportunities to enhance clinical efficacy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
