A <scp>PDE4</scp> shortform degrader: a first in isoform‐specific <scp>PDE4</scp> inhibition
Bibliographic record
Abstract
Although phosphodiesterase 4 (PDE4) inhibitors have reached the clinic, their lack of selectivity for PDE4 enzyme isoforms leads to documented side effects. Building in enzyme selectivity has proved difficult because all PDE4 enzymes share highly conserved catalytic domains. The report by Sin et al. describes a novel approach in which a potent PDE4 proteolysis targeting chimera (PROTAC) selectively promotes the degradation of a small subset of PDE4 isoforms (i.e., "short forms") and impacts inflammatory events regulated by these enzymes. This approach offers unparalleled selectivity, potency, and could represent the dawn of a new pharmacology for selective regulation of cyclic AMP (cAMP) signaling.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
