    摘要: The present disclosure provides modified microRNA nucleic acid compositions that have one or more cytosine and/or uracil bases replaced with gemcitabine or a 5-halouracil, respectively. More specifically, the present disclosure reveals that the replacement of cytosine nucleotides within a microRNA nucleotide sequence with a gemcitabine molecule increases the ability of the microRNA to inhibit cancer progression and tumorigenesis. In addition, the present disclosure reveals that the replacement of cytosine nucleotides within a microRNA nucleotide sequence with a gemcitabine molecule and replacement of uracil bases with 5-halouracil increases the ability of the microRNA to inhibit cancer development. As such, the present disclosure provides various modified nucleic acid (e.g., microRNA) compositions having gemcitabine molecules incorporated in their nucleic acid sequences and methods for using the same. The present disclosure further provides pharmaceutical compositions comprising the modified nucleic acid compositions, and methods for treating cancers using the same.

    摘要: The present invention relates to the field of stereodefined phosphorothioate oligonucleotides and to stereodefining nucleoside monomers and methods of synthesis of stereodefined oligonucleotides using said monomer. Herein are disclosed oligonucleotide enhanced synthesis methods where within a single elongation cycle there are repeated coupling and oxidation steps. The method results in an enhanced yield and higher purity of stereodefined phosphorothioate oligonucleotides
