Ys. Sanghvi et al., CONCEPT, DISCOVERY AND DEVELOPMENT OF MMI LINKAGE - STORY OF A NOVEL LINKAGE FOR ANTISENSE CONSTRUCTS, Nucleosides & nucleotides, 16(7-9), 1997, pp. 907-916
Methylene(methylimino) or MMI linkage is a novel backbone modification
that has enormous potential in the oligonucleotide-based antisense th
erapeutics as a replacement for the natural phosphodiester linkage. Th
is presentation synopsis covers the rationale, detailed SAR on the opt
imization process of this linkage vs. others, various synthetic strate
gies to construct MMI linkage and a brief discussion on the biological
properties of the modified oligonucleotides.
