Glioblastoma is a highly aggressive brain tumor. Current standard-of-care results in marginal therapeutic outcome, partly due to acquirement of resistance and insufficient blood-brain barrier (BBB) penetration chemotherapeutics. To circumvent these limitations, we conjugated the chemotherapy paclitaxel (PTX) dendritic polyglycerol sulfate (dPGS) nanocarrier. dPGS able cross BBB, bind P/L-selectins accumulate selectively intracranial tumors. We show that has dual targeting properties, as...

Physiological barriers inside of tumor tissue often result in poor interstitial penetration and heterogeneous intratumoral distribution nanoparticle-based drug delivery systems (DDS). Novel, matrix metalloproteinase (MMP)-sensitive peptide-crosslinked nanogels (pNGs) as multistage DDS are reported with a beneficial size reduction property to promote the process deep penetration. Methods: The presented pNGs based on dendritic polyglycerol (dPG) scaffold crosslinked by modified MMP-sensitive...

Assembly of the mature human immunodeficiency virus type 1 capsid involves oligomerization protein, CA. The C-terminal domain CA, CTD, participates both in formation CA hexamers and joining through homodimerization. Intact isolated CTD are able to homodimerize solution with similar affinity (dissociation constant order 10 μM); homodimerization mainly an α-helical region. In this work, we show that first-generation gallic acid-triethylene glycol (GATG) dendrimers bind CTD. binding region is...

Polyion complex (PIC) micelles incorporating PEG-dendritic copolymers display an unprecedented stability towards ionic strength that is amplified via hydrophobic interactions. The tridimensional orientation of peripheral linkers between charged groups and the globular/rigid dendritic scaffold maximizes this stabilization compared to PIC from linear polymers. As a result, stable at concentrations higher than 3 M NaCl are obtained, which represents highest saline concentration attained with...

The synthesis of a new family amino-functionalized gallic acid-triethylene glycol (GATG) dendrimers and their block copolymers with polyethylene (PEG) has recently being disclosed. In addition, these have shown potential for gene delivery applications, as they efficiently complex nucleic acids form small homogeneous dendriplexes. On this basis, the present study aimed to explore interaction engineered dendriplexes blood components, well stability, cytotoxicity ability enter transfect...

The development of dendriplexes as nanoarchitectures with sterically induced stoichiometry for gene delivery applications is described. ability four generations amino-functionalized gallic acid−triethylene glycol (GATG) dendrons and PEG−dendritic block copolymers to efficiently condense pDNA was evaluated. A characteristic nitrogen phosphate ratio (N/P) complete condensation revealed each dendrimer. Larger N/P ratios had little effect on the size ξ potential dendriplexes. Dendriplexes are...
