Anti-angiogenic poly-L-lysine dendrimer binds heparin and neutralizes its activity.

The interaction between heparin, a polyanion, and a polycationic dendrimer with a glycine core and lysine branches Gly-Lys63(NH2)64 has been investigated. Complexation was assessed by transmission electron microscopy, size and zeta potential measurements, methylene blue spectroscopy, and measuring the anti-coagulant activity of heparin in vitro and in vivo. Complete association between the hepa...

Poly-L-lysine amplification of protamine immobilization and heparin adsorption.

We previously reported the development of a cellulose fiber based blood filter device containing immobilized protamine (termed protamine filter) that could be used to control both heparin- and protamine-induced complications during extracorporeal therapy. To achieve enhanced heparin adsorption on the fibers, we examined the possibility of utilizing the poly-L-lysine based amplification method t...

Systemic antiangiogenic activity of cationic poly-L-lysine dendrimer delays tumor growth.

This study describes the previously unreported intrinsic capacity of poly-L-lysine (PLL) sixth generation (G(6)) dendrimer molecules to exhibit systemic antiangiogenic activity that could lead to solid tumor growth arrest. The PLL-dendrimer-inhibited tubule formation of SVEC4-10 murine endothelial cells and neovascularization in the chick embryo chick chorioallantoic membrane (CAM) assay. Intra...

Cationic poly-L-lysine dendrimer complexes doxorubicin and delays tumor growth in vitro and in vivo.

We report in this study the complexation of the chemotherapeutic drug doxorubicin (DOX) with the novel sixth-generation cationic poly-l-lysine dendrimer (DM) (MW 8149 kDa), which we previously reported to exhibit systemic antiangiogenic activity in tumor-bearing mice. DOX-DM complexation was confirmed by florescence polarization measurement, proton nuclear magnetic resonance spectroscopy, and m...

Interaction of Poly-l-lysine with Chromatin

The priming capacity of chromatin of fixed nuclei and chromosomes for exogenous DNA polymerase can be evaluated radioautographically by the incorporation of labeled nucleotides. It had previously been reported that acid fixation or acid treatment of alcohol-fixed tissues led to increased priming when calf thymus DNA polymerases, specific for single-stranded DNA, were used. We employed Escherich...
