This invention relates to a composition and its use for formulating
nucleic acid-based drugs / vaccines with
sugar alcohol compositions into complexes for both in-vitro and in-vivo delivery. Particularly, the present invention includes the ingredients and processes necessary for formulating therapeutic and pharmaceutical
nucleic acid compositions, such as miRNA,
microRNA precursors, shRNAs, siRNAs, ribozymes, antisense RNAs / DNAs,
RNA-
DNA hybrids and
DNA vectors / vaccines, with glycylated
sugar alcohols / sugars into delivery complexes, which can then be absorbed by cells
in vivo and
in vitro via active
endocytosis. Also, the present invention discloses that chemical compounds containing
sugar alcohol- and / or sugar-like structures can protect nucleic acids, in particular miRNAs, shRNAs, siRNAs and ribozymes, from degradation
in vivo as well as
in vitro. Therefore, the present invention is also a formula and method for preserving the
structural integrity and functional
efficacy of these
nucleic acid-based drugs and / or vaccines
in vivo and
in vitro.
