Article Title: Etoposide-loaded lipopolymer nanoparticles promote Smac minetic activity against inhibitor of apoptosis protein for glioblastoma treatment.
Article Snippet: Encapsulated BV6 and SM164, two bivalent second mitochondria-derived activator of caspase (Smac) mimetics, in etoposide (ETO)-lipopolymer nanoparticles (NPs) have been developed to deplete inhibitor of apoptosis proteins (IAP), impair DNA, and produce antagonistic effects on glioblastoma multiforme (GBM) in nude mice.. The NPs, composed of cocoa butter (CB) and polyvinyl alcohol (PVA), were stabilized by glycerol monostearate and Pluronic F-127, and grafted with transferrin (Tf) and wheat germ agglutinin (WGA) to dock the blood-brain barrier (BBB) and degenerated dopaminergic neurons.. The dual-targeting NPs increased the BBB permeability of BV6, SM164 and ETO via recognizing Tf receptor (TfR) and N-acetylglucosamine that are abundantly expressed on brain microvascular endothelial cells.

Article Title: Suppressed XIAP and cIAP expressions in human brain cancer stem cells using BV6- and GDC0152-encapsulated nanoparticles
Article Snippet: Background: Smac mimetics functioned against inhibitors of apoptosis proteins (IAP) often fail to achieve sufficient ability in glioblastoma multiforme (GBM) treatment due to the obstruction of the blood-brain barrier (BBB).. Methods: BV6and GDC0152-encapsulated solid lipid nanoparticles (SLNs) with surface transferrin (Tf) and folic acid (FA) (BV6-GDC0152-Tf-FA-SLNs) were developed to downregulate IAP in U87MG cells and human brain cancer stem cells (HBCSCs) for GBM treatment.. Significant findings: An increase in stearic acid (SA) level enlarged SLNs with improved entrapment of BV6 and GDC0152.
