WebJan 28, 2024 · Another preferred chemistry is the phosphorodiamidate morpholino oligomer (PMO) oligomeric compounds that are not degraded by any known nuclease or protease. These compounds are uncharged, do not activate RNase H activity when annealed to an RNA strand and have been shown to exert sustained splice modulation after in vivo … A Morpholino, also known as a Morpholino oligomer and as a phosphorodiamidate Morpholino oligomer (PMO), is a type of oligomer molecule (colloquially, an oligo) used in molecular biology to modify gene expression. Its molecular structure contains DNA bases attached to a backbone of … See more Morpholino oligos were conceived by Summerton (Gene Tools) at AntiVirals Inc. (now Sarepta Therapeutics) and originally developed in collaboration with Weller. See more Morpholinos do not trigger the degradation of their target RNA molecules, unlike many antisense structural types (e.g., See more Morpholinos have become a standard knockdown tool in animal embryonic systems, which have a broader range of gene expression than adult cells and can be strongly affected by an off-target interaction. Following initial injections into frog or fish embryos … See more • Wiley-Liss, Inc. Special Issue: Morpholino Gene Knockdowns of genesis Volume 30, Issue 3 Pages 89-200 (July 2001). This is a special issue of Genesis that consists of a series of peer-reviewed short papers using Morpholino knock downs of gene function in various … See more Morpholinos are synthetic molecules that are the product of a redesign of natural nucleic acid structure. Usually 25 bases in length, they bind to complementary sequences of RNA or single-stranded DNA by standard nucleic acid base-pairing. In terms of structure, … See more For a Morpholino to be effective, it must be delivered past the cell membrane into the cytosol of a cell.

WebThe first step in preparing Morpholino oligos is to convert ribonucleosides to Morpholino subunits as shown in Figure 1. Figure 1. Morpholino subunits are subsequently protected with a trityl and activated with our phosphoroamidate linking agent, as shown in Figure 2. Figure 2. Oligo Assembly WebPhosphorodiamidate morpholinos (PMOs) and PMO–DNA chimeras have been prepared on DNA synthesizers using phosphoramidite chemistry. This was possible by first generating boranephosphoroamidate morpholino internucleotide linkages followed by oxidative substitution with four different amines: N,N-dimethylamine, N-methylamine, ammonia, and … WebThis is the first clinical data from SRP-5051, an investigational treatment that uses Sarepta’s peptide phosphorodiamidate morpholino oligomer (PPMO) technology.
