Hydrogelation abilities of nucleobase-modified cytidines possessing substituted triazoles
Bibliographic record
Abstract
Nucleoside-derived hydrogelators have been sought for their potential biomedical applications, such as are found in tissue engineering and drug delivery. By judiciously adding a degree of hydrophobicity certain analogues are able to form micelles, bi-layers and gels in water. Research in this area has yet to lay down solid ground rules for the rational design of novel nucleoside gelators making further studies necessary. The synthesis and examination of a series of aryl-substituted 5-triazolylcytidines yielded an analogue that gelates water. 5-(1-(2,2'-bithiophen-3-yl)-1H-1,2,3-triazol-4-yl)-2'-deoxycytidine was found to form gels in water down to 0.3 wt%. The ribocytidine analogue failed to form gel in aqueous solution; but was able to form a hydrogel in the presence of guanosine. Images obtained by SEM show the different architectures of the gel; varying from cribriform to fibrous to lamellar. The present gelating compound studied may have potential as a component of a controlled-release drug delivery system.

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.
