SPIONs embedded in polyamino acid nanogels to synergistically treat tumor microenvironment and breast cancer cells.
2018
Abstract The extremely complex tumor microenvironment (TME) in humans is the major responsible for the therapeutic failure in cancer nanomedicine. A new concept of disease-driven nanomedicine, henceforth named “Theranomics”, which attempts to target cancer cells and TME on the whole, represents an attractive alternative. Herein, a nanomedicine able to co-deliver doxorubicin and a tumor suppressive proteolytic protein such as collagenase-2 was developed. We successfully obtained superparamagnetic nanogels (SPIONs/Doco@Col) via the intermolecular azide-alkyne Huisgen cycloaddition. We demonstrated that a local ECM degradation and remodeling in solid tumors by means of collagenase-2 could enha…
Polyamino Acid Carriers In Drug Delivery And Their Production Under Good Manufacturing Practice Compliance
2021
Poly(Amino Acids) (PAA)s are biocompatible, biodegradable and multifunctional polymers, which have been effectively used as building blocks in polymer-based delivery carriers for various medical applications. In addition, PAAs are envisaged to achieve a major impact on biomedical areas due to their structural versatility, biocompatibility, water-solubility and the important advances made on the synthetic strategies. Control on polymer chain length and stereochemistry have been one of the major challenges in PAA synthesis over the past years. Their physico-chemical properties can be modulated in terms of the manufacturing process, size, electrostatic charge, conformation, geometry, topology,…
