Influences of Histidine-1 and Azaphenylalanine-4 on the Affinity, Anti-inflammatory, and Antiangiogenic Activities of Azapeptide Cluster of Differentiation 36 Receptor Modulators
Bibliographic record
Abstract
Azapeptide analogues of growth hormone releasing peptide-6 (GHRP-6) exhibit promising affinity, selectivity, and modulator activity on the cluster of differentiation 36 receptor (CD36). For example, [A 1, azaF 4 ]- and [azaY 4 ]-GHRP-6 ( 1a and 2b ) were previously shown to bind selectively to CD36 and exhibited respectively significant antiangiogenic and slight angiogenic activities in a microvascular sprouting assay using choroid explants. The influences of the 1- and 4-position residues on the affinity, anti-inflammatory, and antiangiogenic activity of these azapeptides have now been studied in detail by the synthesis and analysis of a set of 25 analogues featuring Ala 1 or His 1 and a variety of aromatic side chains at the aza-amino acid residue in the 4-position. Although their binding affinities differed only by a factor of 17, the analogues exhibited significant differences in ability to modulate production of nitric oxide (NO) in macrophages and choroidal neovascularization.

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.
