  • Metabolic Profiling of Urinary Chiral Amino-Containing Biomarkers for Gastric Cancer Using a Sensitive Chiral Chlorine-Labeled Probe by HPLC-MS/MS.: This study by Huang et al. (2021) explores the use of D-Isoleucine as a biomarker for gastric cancer, utilizing advanced metabolic profiling techniques with HPLC-MS/MS to detect chiral amino-containing compounds in urine samples (Huang et al., 2021).

  • Isopenicillin N Synthase Binds δ-(L-α-aminoadipoyl)-L-cysteinyl-D-thia-allo-isoleucine Through Both Sulfur Atoms.: Clifton et al. (2011) describe the binding mechanism of Isopenicillin N synthase with a compound involving D-Isoleucine, highlighting its role in antibiotic biosynthesis and enzyme interaction studies (Clifton et al., 2011).

  • The Total Structure of the Antibiotic Longicatenamycin.: Shiba and Mukunoki (1975) determined the complete structure of the antibiotic longicatenamycin, which includes D-Isoleucine as a crucial component, contributing to understanding its antibacterial properties (Shiba and Mukunoki, 1975).

Biochem/physiol Actions

D-Isoleucine may be used to help characterize and differentiate various D-amino acid oxidases. D-Isoleucine may be used to differentiate the activities of D- and L-isoleucine in processes such as the induction of pigmentation in B16F0 melanoma cells.
