Application

  • Integrated metabolomic and transcriptomic analysis reveals the regulatory mechanisms of flavonoid and alkaloid biosynthesis in the new and old leaves of Murraya tetramera Huang.: This study examines the biochemical pathways in Murraya tetramera, with a focus on the interaction between flavonoids and alkaloids, which may include imidazole-based compounds (Zhou et al., 2024).
  • Unraveling the complex nexus: Interplay of volatile compounds, free amino acids, and metabolites in oat solid state fermentation.: Discusses the roles of various biochemicals, including potentially imidazole, in oat fermentation, providing insights into food science and biochemistry (Sun et al., 2024).
  • Application of copper (I) selective ligands for PET imaging of reactive oxygen species through metabolic trapping.: This article explores the use of imidazole ligands in PET imaging, contributing to advanced techniques in medical imaging and diagnostics (Tada et al., 2024).
