This invention features methods and compositions for delivery of nucleic acids (e.g., DNA, RNA, PNA, and hybrids thereof) to cells. The nucleic acid delivery complexes of the invention permit biologically active nucleic acids to be delivered to cells and organisms in vitro and in vivo in a manner and form that allows the nucleic acids to carry out their desired biological function.
Abstract The reaction of spermine with aromatic aldehyde leads to an equilibrated system between the bis imine form 1' and the hexahydropyrimidine form 1. In contrary the formaldehyde adduct of spermine exist only on the hexahydropyrimidine form 9. 1–1' is readily hydrolyzed by HCl with regeneration of the aldehyde and spermine. The NaBH4, reduction of 1–1' leads to the dibenzyl spermine 8 and the
