Peptides and Oligonucleotides (TIDES)

Small but mighty. Achieve enhanced characterization of complex oligonucleotides and peptides (TIDES) using state-of-the-art technology and methods.

Highlights

Sensitive
Accelerate structure assignments and pinpoint structural changes with new probe and magnet technologies
Selective
Leverage acquisition of select nuclei such as 31P or 19F for even greater selectivity and resolution
Quantitative
Accurately determine absolute content or measure the PS to PO linkage ratio of oligos without reference material

Peptides and oligonucleotides (TIDES) are important and potent therapeutic modalities in targeting many diseases: diabetes, cancer, osteoporosis, cardiovascular diseases, genetic disorders, and other rare diseases to name a few. Nuclear magnetic resonance (NMR) spectroscopy is the best-suited, high-resolution technique for structure characterization of these modalities, including higher order structure (HOS), chiral identification, and comparability and similarity assessments. The inherent benefits (specificity, safety, efficacy, druggable indications, and low cost) of TIDES has led to a growing interest in R&D in the biopharmaceutical industry: from 2016 and 2023 TIDES make up about 13% of all FDA-approved new drug entities1-6. Recent FDA and EMA draft guidance documents8-10 demand enhanced characterization of TIDES (including distinguishing stereoisomeric character), which calls for state-of-the-art analytical techniques and NMR is recommended to meet these needs.

NMR is widely viewed as the “gold standard” for chemical structure characterization of various and advances in sensitivity, resolution, and data processing enables detailed characterization to support discovery, development, and manufacturing of TIDES. The introduction of the Ascend Evo instruments improves the accessibility of magnets at higher field strengths, especially the 1 GHz instrument, to be employed for TIDES characterization because of the reduction in footprint and maintenance of cryogenic fluids. The gain in resolution at higher field strengths accelerates the assignment process of peptides and facilitates the characterization of the enantiomeric complexity of oligos, both of which are important in therapeutic development. Additionally, the development in probe technology improves the mass-sensitivity at common field strengths (500 and 600 MHz) and allows for direct detection of nuclei unique to oligos. The 3 mm Multi-Nuclear Inverse (MNI) CryoProbe™ enhances sensitivity relative to other similar CryoProbes (e.g., 5 mm TCI CryoProbe) to further accelerate the assignment of peptides and has a channel tunable to 19F and 31P for enhanced characterization of oligos. Despite the chemical and dynamic complexity of peptides and oligos, these improvements to NMR technology enable scientists to rise to the challenge of TIDES characterization to ensure patient safety.

Validation and implementation of qNMR as platform methods of oligonucleotides and peptides

The content of e.g peptides or oligonucleotides in a sample (solid or liquid) is of importance in many aspects. For peptides traditional methods like Kjeldahl nitrogen determination, elementary analysis (EA), and amino acid analysis (AAA), requires break down of the protein at harsh conditions to determine the protein content. For oligonucleotides one of the most widely used techniques for quantification is ultraviolet (UV) spectroscopy.

NMR spectroscopy, just what you need to assure the quality of your TIDES!

The wealth of structural information that accompanies NMR spectroscopy has made it instrumental for traditional small molecules medicinal and analytical chemistry support. Perhaps less well known is its ability to characterise TIDES efficiently and with such a level of detail (atomic resolution). This talk demonstrates its power with examples covering TIDES structure-based drug design,1,2 similarity assessment,3 characterisation,4 secondary and tertiary structure, quantification and phosphorothioate chirality.5,6
