Methylphosphonate oligo
Webneutral analogs, methylphosphonate oligo-mers (Figure 2-1a) and phosphoramidates (Figure 2-1b) have been readily prepared on solid supports. Although these analogs have an increased resistance to nucleases, they show a lower RNA binding affinity than natural phosphodiester-based parent se-quences. This reduced affinity has been at-DNA mRNA ... Webused to solubilize the oligo. Methyl phosphonoamidites are deoxynucleoside amidites modified such that, when incorporated into an oligonucleotide, that base position will have a (electrically neutral) methyl phosphonate backbone linkage instead of the standard (negatively charged) phosphodiester linkage. Oligos containing one or more methyl ...

Web15 aug. 2016 · For instance, oligos built up with methylphosphonate, phosphorothioate and α-anomer units (see fig. 1) lead to molecules that are resistant to DNases. Acridinelinked oligos exhibit an increased affinity for the target sequence due to the intercalation of the dye into the oligo/RNA duplex. Web1 jun. 1991 · Highly modified phosphorothioates or methylphosphonates are less stable than their partially modified counterparts which are less stable than the unmodified parent compounds. The 'normal' (2'-OH) RNA analog of duplex D1 is slightly destabilized, whereas the 2'-OCH3 RNA derivative is significantly stabilized relative to the unmodified DNA.
