Abstract

Quercetin (QCT) is a flavonoid, abundantly present in plants and has gained considerable interest for its antioxidant property and chemo preventive activity. Bioavailability of QCT is very low due to its poor aqueous solubility and instability. Researchers are working on the application of nanotechnology to target chemotherapeutic drugs to the tumour site. The aim of the present study was to develop quercetin loaded chitosan nanoparticles (QCT-CS NPs) with enhanced encapsulation efficiency and sustained release property. We prepared biocompatible NPs with small size (<200 nm) and encapsulation efficiency of 79.78%. In vitro drug release study exhibited a cumulative amount of 67.28% release of QCT over a period of 12 h. at pH 7.4. In vitro cytotoxicity assay showed significantly reduced IC50 value of QCT-CS NPs as compared to free QCT (p < 0.05). Intra venous treatment of QCT-CS NPs in tumour xenograft mice with A549 and MDA MB 468 cells exerted significant reduction of tumour volume in comparison to disease control groups (p < 0.05). Serum anti oxidant enzyme superoxide dismutase (SOD) level markedly increased in QCT-CS NPs treated tumour bearing mice than free QCT treated group. In summary, the recent investigations reported successful encapsulation of QCT in chitosan (CS) NPs to target the tumour microenvironment and exhibited enhanced efficacy of QCT-CS NPs in cancer therapy.

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.
