Abstract
In this study, statistical glyco-dithiocarbamate (DTC) copolymers were synthesized by reversible addition-fragmentation chain transfer polymerization (RAFT) and subsequently used to prepare glyconanoparticles and conjugated glyconanoparticles with the anticancer drug, gold(I) triphenylphosphine. These glyconanoparticles and the corresponding conjugates were then tested for their in vitro cytotoxicity in both normal and cancer cell lines using Neutral Red assay. The glyconanoparticles and their Au(I)PPh3 conjugates were all active against MCF7 and HepG2 cells, but galactose-functionalized glyconanoparticles {P(GMA-EDAdtc(AuPPh3)-st-LAEMA)AuNP} were found to be the most cytotoxic to HepG2 cells (IC50 ∼ 4.13 ± 0.73 μg/mL). The p(GMA-EDAdtc(AuPPh3)-st-LAEMA)AuNP was found to be a 4-fold more potent antitumor agent in HepG2 cells, and the overexpressed asialoglycoprotein (ASGPR) receptors revealed to play an important role in the cytotoxicity, presumably by the enhanced uptake. In addition, the glyconanoparticles Au(I) conjugates are found to be significantly more toxic as compared to the standard chemotherapeutic reagents such as cisplatin and cytarabine.

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 it
