Cholic Acid-Modified Dendritic Multimolecular Micelles and Enhancement of Anticancer Drug Therapeutic Efficacy
Bibliographic record
Abstract
To improve the efficacy and bioacceptability of polyamidoamine (PAMAM) in potential biomedical applications, the PAMAM dendrimers (first generation) were partially modified with cholic acid. (1)H NMR studies and acid-base titration show that two cholic acid molecules are linked to one PAMAM. The modified PAMAM dendrimers self-assemble to form dendritic multimolecular micelles in aqueous solutions, with a diameter of 120 nm measured by dynamic light scattering. These micelles can encapsulate hydrophobic drug molecules in aqueous media and exhibit pH sensitivity. The in vitro results demonstrate that the anticancer activity of camptothecin is significantly enhanced at low drug dose after being encapsulated by these micelles in the presence of serum. Therefore, the dendritic multimolecular micelles based on low generation dendrimers may have potential applications in the delivery 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.
