Glycopolymers Bearing Galactose and Betulin: Synthesis, Encapsulation, and Lectin Recognition
Bibliographic record
Abstract
Betulin is a natural triterpene compound with anticarcinogen and antiviral activities. It is conjugated with methacrylate and then copolymerized with a galactose-bearing comonomer by RAFT polymerization to yield both random and block copolymers. These glycopolymers are designed to possess similar molecular weights and monomer compositions for easy comparison. They self-assembled into micelles, as shown by dynamic light scattering (DLS) and transmission electron microscopy. The smaller micelles formed by the random copolymers facilitated the encapsulation of Nile Red and released more of this hydrophobic model compound (46% in 4 days versus 32% released from the block copolymers). These glycopolymers interacted with lectins, such as RCA 120, as studied by turbidity assay and DLS. The block copolymers formed larger aggregates and clustered faster than the random copolymers. The betulin-based glycopolymers may serve as biocompatible multifunctional biomaterials and carriers for use in targeted release of drugs.

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.
