Lipidic inhibitors of human N-myristoyltransferase
Bibliographic record
Abstract
This study was undertaken in order to identify compounds which inhibit the activity of human myristoyl-CoA:protein N-myristoyltransferase (hNMT). In particular, the structural features of such molecules which contribute to enzyme inhibition were investigated. Two groups of compounds, namely myristic acid and analogs 1-13 and derivatives of myristoyl-CoA 14-19 were evaluated. All compounds were examined using cAMP-dependent protein kinase derived peptide substrate. The IC(50) values were <1 micro M, between 1 and 100 micro M or >100 micro M in eight, four and seven compounds, respectively. Of the six myristoyl-CoA analogs, five had IC(50) values in the 0.06-0.59 micro M range. These molecules were examined using three additional substrates viz pp60src, MARCKS and M2 gene segment of reovirus type 3 which led to results similar to those obtained with the cAMP-dependent protein kinase substrate. On the other hand, evaluation of myristic acid and four related compounds revealed some differences in hNMT-inhibiting properties among the substrates. From the results obtained, the possible manner whereby potent inhibitors interact with the enzyme was formulated thus enabling the design of further analogs as candidate inhibitors of hNMT.

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.
