Trimethylglycylglycerin compositions and their use in developing anti-cancer drugs and RNA vaccines
This invention generally relates to a group of novel chemical compositions and their use for formulating RNA- and/or DNA-based medicine drugs/vaccines into stable compound complexes useful for both in-vitro and in-vivo delivery. Particularly, the present invention teaches the synthesis of a group of novel trimethylglycyl chemicals and their use for formulating cosmetic, therapeutic- and/or pharmaceutical-grade nucleic acid compositions, including but not limited microRNA precursors (pre-miRNA/miRNA), small hairpin RNAs (shRNA), short interfering RNAs (siRNA), ribozymes, antisense oligonucleotides, RNA-DNA hybrids and DNA-based vectors/vaccines, with or without modification, into delivery complexes, which can then be absorbed by cells in vivo, ex vivo and/or in vitro through an active mechanism of endocytosis via acetylcoline receptors for releasing the therapeutic and pharmaceutical effects of the formulated nucleic acid compositions.
