Diversity‐Oriented Synthesis of Cyclic Azapeptides by A<sup>3</sup>‐Macrocyclization Provides High‐Affinity CD36‐Modulating Peptidomimetics
Bibliographic record
Abstract
Abstract Macrocyclization has enabled the use of peptides in drug discovery creating a need for methods to synthesize diverse peptide macrocycles. Azapeptides have advanced to clinically used drugs, however, few cyclic azapeptides have been studied. A multiple component “A 3 ‐macrocyclization” strategy is described for the preparation of diverse cyclic azapeptides and is demonstrated by the synthesis of 15 growth hormone releasing hormone‐6 (GHRP‐6) analogs. Certain cyclic aza‐GHRP‐6 analogs exhibited unprecedented affinity for the CD36 receptor, and capacity to modulate Toll‐like receptor agonist‐induced overproduction of nitric oxide, and reduce pro‐inflammatory cytokine and chemokine production in macrophages.

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.
