Self-Assembled Lipoplexes of Short Interfering RNA (siRNA) Using Spermine-Based Fatty Acid Amide Guanidines: Effect on Gene Silencing Efficiency [PDF]

Pharmaceutics, 2011
Four guanidine derivatives of N4,N9-diacylated spermine have been designed, synthesized, and characterized. These guanidine-containing cationic lipids bound siRNA and formed nanoparticles. Two cationic lipids with C18 unsaturated chains, N1,N12-diamidino-

Efficient Cleavage of pUC19 DNA by Tetraaminonaphthols [PDF]

ChemistryOpen
In an attempt to create models of phosphodiesterases, we previously investigated bis(guanidinium) naphthols. Such metal‐free anion receptors cleaved aryl phosphates and also plasmid DNA.
