Abstract

In part because of their high drug loading, nanocrystals (NCs) have seen extensive use in drug delivery, particularly for insoluble or poorly soluble drugs. It remains a challenge, however, to prepare stable nanocrystals with tumor-targeting capability. Here, we designed a novel preparation of stable paclitaxel (PTX) nanocrystals with efficient active tumor-targeting properties. PTX NC was prepared using a bottom-up method and modified with both poly(ethylene glycol) (PEG) and folic acid (FA) derivatives using film hydration. The resulting PTX NC@lipid–PEG–FA had a rodlike shape, with hydrodynamic diameters and drug loading values of 201.90 ± 2.92 nm and 31.07 ± 3.41%, respectively. The size of the PTX NC@lipid–PEG–FA was unchanged after 168 h in the presence of plasma, whereas nonmodified paclitaxel nanocrystals (PTX NC) exceeded 600 nm within 12 h under the same conditions. Cellular uptake and cellular growth inhibition experiments in 4T1 breast cancer cells showed the superiority of PTX NC@lipid–PEG–FA over PTX NC or PEGylated paclitaxel nanocrystals without FA modification (PTX NC@lipid–PEG). A pharmacokinetic evaluation in rats revealed that PTX NC@lipid–PEG–FA significantly prolonged the circulation of PTX in the bloodstream, in comparison with PTX NC or Taxol. Tissue distribution and in vivo antitumor studies in 4T1 orthotopic breast cancer-bearing nude mice showed that PTX NC@lipid–PEG–FA significantly increased the intratumor accumulation of PTX and efficiently inhibited tumor growth, in comparison with PTX NC@lipid–PEG, PTX NC, or Taxol. In summary, PTX NC@lipid–PEG–FA showed good potential for breast cancer-targeted delivery for insoluble therapeutics.

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.
