Japanese Drug Discovery Advances
Japanese scientists have developed a new approach designed to overcome complexities of developing new, more effective drugs to treat diseases, including cancer.
Japanese scientists have developed a new approach designed to overcome complexities of developing new, more effective drugs to treat diseases, including cancer. This approach is focused on advancements in protein identification and quantification, which are reported to have been made possible by new-generation AB Sciex mass spectrometry technology and Eksigent chip-based nanoLC technology.
Dr Tetsuya Terasaki and his team at Tohoku University, Japan are claiming to identify and quantify a much wider range of drug transporter proteins, functional proteins and enzymes that activate or inactivate drugs in the body helping to accelerate the process of advancing protein biomarkers for future use in diagnostics.
Their research uses the AB Sciex TripleTOF 5600 System and Eksigent cHiPLC-nanoflex system, which the companies claim helps reproduce assays more easily than previously possible.
"AB Sciex promised to help us push the limits of pharmaceutical science, and they have done exactly that”, said Dr Terasaki. “With the support of AB Sciex we are accelerating biomedical research to develop new paths to drug discovery and development intended to improve diagnostics and treatment for the good of humanity."

The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
Metabolomics Analysis of Low Birth-Weight Infants Using UHPLC-MS/MS Following Lipid Emulsion
January 10th 2025A recent study aimed to directly compare the changes in serum metabolites among very low birth-rate (VLBW) infants following the administration of the soybean oil-based lipid emulsion and soybean oil, medium-chain triglycerides, olive oil, and fish oil (SMOF) lipid emulsion using untargeted metabolomics techniques.
