Phosphorodiamidate Morpholino Oligomers (PMO)
Phosphorodiamidate Morpholino Oligomers (PMO) are a type of oligonucleotide molecule. These short, single-stranded DNA analogs are built upon a backbone of morpholine rings connected by phosphorodiamidate linkages. Although they are routinely used for gene silencing and have been developed into excellent antisense reagents in PMO-based drugs, synthesizing PMO remains a challenging task.
At WuXi TIDES, we have developed a high loading solid-phase PMO synthesis process. This process achieves over 50% yield, over 75% crude purity, and more than 90% final product purity with less than 0.045 EU/mg endotoxin. Our chemistry know-how allows us to make various PMO 5′ modifications with an improved cleavage & de-protection process. Our optimized process also offers freedom to operate without IP concerns.
To support large-scale production, we have customized PMO synthesis reactors up to 100L. Our team has successfully completed PMO development and manufacturing projects on a kilogram scale.

Our oligonucleotide and peptide API platforms are both located at our site in Changzhou, China. This strategic location is well-suited for the development and manufacturing of oligonucleotide and peptide conjugates, especially Peptide-PMO (PPMO). To date, our team has successfully completed dozens of PPMO projects. The following case study illustrates how our cross-functional teams seamlessly collaborate with in-parallel activities, providing a fast, efficient, and flexible solution for PPMO development.

Oligonucleotide Conjugate
When your oligonucleotide conjugate drugs enter the preclinical phase, you may encounter challenges if your synthesis methodology or conjugation techniques aren’t suitable for scale-up or first-in-human needs.
WuXi TIDES is well positioned to provide a one-stop solution for complex oligonucleotide-base conjugated drugs, from discovery through development to commercial manufacturing. Our strong capabilities extend to oligonucleotides and small molecules, including ligands, toxins, linkers, lipids, PEG, and more. With readily scalable facilities, we offer integrated CMC services and highly reliable solutions for developing and manufacturing oligonucleotide APIs and all common ligands. We also provide conjugation chemistry to streamline your projects from preclinical studies to clinical trials. Our dedicated teams significantly reduce the time required for CTM batches and simplify material transfers.

In additon to discovery synthesis, we offer amidite process development and manufacturing services, with dedicated plants specifically for amidite production. Besides, we established amidite impurity control strategy by systematically conducting assessment of amidite impurities and their impact on oligonucleotide API quality. During the process, 1,000+ amidite impurities were synthesized.
Among 500+ catalog amidites in stock, we also provide 40+ amidite products available at commercial scale, including DNA, 2’-MOE, 2’-OMe, 2’-F, LNA, PMO monomer, etc. Selected common amidite DMFs available.
