Immunosuppressant drugs are extremely important for therapeutic drug monitoring (TDM) regimes, requiring robust and reliable methods for their analysis. This poster aims to demonstrate strategies for the extraction of various immunosuppressant drugs from whole blood providing clean samples prior to UPLC-MS/MS analysis. Spiked whole blood was extracted using a variety of protocols to investigate optimal combination of drug recovery and extract cleanliness. UPLC-MS/MS was conducted using a Waters ACQUITY UPLC coupled to a Quattro Premier XE triple quadrupole mass spectrometer. Acceptable extraction recoveries were obtained showing excellent extract cleanliness, demonstrating a reliable method for mass spectrometric approaches for these analytes.

Reversed-phase chromatography is typically used when you need to separate several milligrams of relatively polar compounds that either are not soluble in normal-phase solvents or are not compatible with bare silica
because they react, stick, or both. If you are currently using reversed-phase at preparative scale, such as flash chromatography, you know the mobile phase limitations – water with either methanol, acetonitrile, or
THF. As with normal-phase flash chromatography, when it comes time to purify you want your crude sample fully solubilized in the weakest possible solvent at the highest possible concentration.

Pyrazines are a class of organic molecules often used to provide flavor to foods. They are typically synthesized but some are found in fruits and vegetables, e.g. grapes, bell peppers, peas, asparagus, beetroot, tobacco, and roasted foods. Pyrazine’s heterocyclic chemistry can yield some challenges to their purification due to the various separation kinetics between the compound and silica. Biotage SNAP Ultra.

Although capable of very high resolution, RP-HPLC is often limited by low column loading capacity, therefore demanding a significant time investment for peptide purification. As an alternative strategy, reversed-phase flash chromatography can also be used to purify synthetic peptides. The larger particle size used in flash column chromatography enables much larger loading capacity, thereby significantly reducing the time required for peptide purification.

Normal-phase flash purification is commonly used by organic chemists in pharmaceutical drug discovery and
process development labs. However, for many synthesized products (e.g. peptides, nucleotides and basic
drug candidates) purification on standard flash silica is not an option due to irreversible adsorption, chemical
interaction and/or solubility issues. Reversed-phase flash purification is an excellent solution for these applications. Yet, this technique has been used sparingly because of perceived lower loading capacity, higher
operating pressures and a scarcity of publications addressing reversed-phase flash chromatography.

For pilot and production scale purification drugs, the use of a large particle-size media is common. Improving the purification throughput is limited by the media’s large particle size. Such a case was recently encountered when a pharmaceutical company attempted to improve the efficiency of a large-scale purification. In their current process, the use of a 350-600 µm polystyrene-type resin resulted in a lengthy purification cycle and low separation efficiency. However, the labile properties of the targeted component required a shorter purification cycle and high purification.

Traditional RP-HPLC techniques not always critical because improvements in solid-phase peptide synthesis techniques over the years (microwave heating and ChemMatrix® solid phase supports) have reduced the burden on downstream purification steps. Mass directed flash purification can be a viable alternative to more expensive (and lower capacity) semi- or prep-scale RP-HPLC methods.
