Despite its surpassing therapeutic potential, its clinical utility is hampered by its low systemic bioavailability. Accordingly, as far as we are aware, this is the first study to develop lactoferrin-coated FS-loaded \u03b2-cyclodextrin nanosponges (LF-FS-NS) for targeted FS delivery to breast cancer. NS formation through cross-linking of \u03b2-cyclodextrin by diphenyl carbonate was confirmed by FTIR and XRD. The selected LF-FS-NS showed good colloidal properties (size 52.7 \u00b1 7.2 nm, PDI &lt; 0.3, and \u03b6-potential 24 mV), high loading efficiency (96 \u00b1 0.3%), and sustained drug release of 26 % after 24 h. Morphological examination using SEM revealed the mesoporous spherical structure of the prepared nanosponges with a pore diameter of ~30 nm, which was further confirmed by surface area measurement. Additionally, LF-FS-NS enhanced FS oral and IP bioavailability (2.5- and 3.2-fold, respectively) compared to FS suspension in rats. Antitumor efficacy evaluation in vitro on MDA-MB-231 cells and in vivo on an Ehrlich ascites mouse model demonstrated significantly higher activity and targetability of LF-FS-NS (30 mg\/kg) compared to the free drug and uncoated formulation. Consequently, LF-FS-NS could be addressed as a promising formulation for the effective management of breast cancer.<\/jats:p>","DOI":"10.3390\/pharmaceutics15051480","type":"journal-article","created":{"date-parts":[[2023,5,12]],"date-time":"2023-05-12T09:26:13Z","timestamp":1683883573000},"page":"1480","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Targeted Fisetin-Encapsulated \u03b2-Cyclodextrin Nanosponges for Breast Cancer"],"prefix":"10.3390","volume":"15","author":[{"given":"Alaa R.","family":"Aboushanab","sequence":"first","affiliation":[{"name":"Department of Pharmaceutics, Faculty of Pharmacy, Alexandria University, Alexandria 21525, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Riham M.","family":"El-Moslemany","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutics, Faculty of Pharmacy, Alexandria University, Alexandria 21525, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8773-5365","authenticated-orcid":false,"given":"Amal H.","family":"El-Kamel","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutics, Faculty of Pharmacy, Alexandria University, Alexandria 21525, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9048-4464","authenticated-orcid":false,"given":"Radwa A.","family":"Mehanna","sequence":"additional","affiliation":[{"name":"Department of Medical Physiology, Faculty of Medicine, Alexandria University, Alexandria 21525, Egypt"},{"name":"Center of Excellence for Research in Regenerative Medicine and Applications (CERRMA), Faculty of Medicine, Alexandria University, Alexandria 21525, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Basant A.","family":"Bakr","sequence":"additional","affiliation":[{"name":"Department of Zoology, Faculty of Science, Alexandria University, Alexandria 21525, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asmaa A.","family":"Ashour","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutics, Faculty of Pharmacy, Alexandria University, Alexandria 21525, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8398","DOI":"10.1021\/ma951673i","article-title":"From a Dissolved Polystyrene Coil to an Intramolecularly-Hyper-Cross-Linked \u201cNanosponge\u201d","volume":"29","author":"Davankov","year":"1996","journal-title":"Macromolecules"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"726","DOI":"10.1016\/j.jsps.2022.03.019","article-title":"Abemaciclib-loaded ethylcellulose based nanosponges for sustained cytotoxicity against MCF-7 and MDA-MB-231 human breast cancer cells lines","volume":"30","author":"Anwer","year":"2022","journal-title":"Saudi Pharm.
