Abstract

A combination of molecular dynamics (MD) simulations and docking calculations was employed to model and predict polymer-drug interactions in self-assembled nanoparticles consisting of ABA-type triblock copolymers, where A-blocks are poly(ethylene glycol) units and B-blocks are low molecular weight tyrosine-derived polyarylates. This new computational approach was tested on three representative model compounds: nutraceutical curcumin, anticancer drug paclitaxel and prehormone vitamin D3. Based on this methodology, the calculated binding energies of polymer-drug complexes can be correlated with maximum drug loading determined experimentally. Furthermore, the modeling results provide an enhanced understanding of polymer-drug interactions, revealing subtle structural features that can significantly affect the effectiveness of drug loading (as demonstrated for a fourth tested compound, anticancer drug camptothecin). The present study suggests that computational calculations of polymer-drug pairs hold the potential of becoming a powerful prescreening tool in the process of discovery, development and optimization of new drug delivery systems, reducing both the time and the cost of the process.

  • MD simulation could rank order drugs by their loading in polymeric micelles in good agreement with experimental data.

    “MD simulation could also rank order drugs by their loading in polymeric micelles in a good agreement with experimental data.”

    From Polymeric micelles for the delivery of poorly soluble drugs: From nanoformulation to clinical approval. (2020) · cites this paper as [206]

    The Conclusion reports that a model combining MD simulations with docking calculations rank-ordered three drugs by experimentally observed maximum loading. The study tested tyrosine-derived polymeric nanospheres, not polymeric micelles, and does not establish that MD simulation alone produced the ranking. (LLM, conf=0.87)

  • Costache et al. used MD and docking to predict preferred drug orientation to polymer and rank curcumin, paclitaxel, and vitamin D3 by binding energies with specific micelles.

    “For example, Costache et al. used a combination of MD and docking calculations which predict preferred orientation of a drug to a polymer for ranking three drugs (curcumin, paclitaxel and vitamin D3) by the energies of binding of with PEG-b-oligo(desaminotyrosyl-tyrosine octyl ester suberate)-b-PEG micelles [206].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
