Lifitegrast-d4-1

Lifitegrast-d₄-1 is deuterium labeled Lifitegrast. Lifitegrast (SAR 1118) is a potent integrin antagonist. Lifitegrast blocks the binding of intercellular adhesion molecule 1 (ICAM-1) to lymphocyte function-associated antigen 1 (LFA-1), interrupting the T cell-mediated inflammatory cycle. Lifitegrast inhibits Jurkat T cell attachment to ICAM-1 with an IC₅₀ of 2.98 nM. Lifitegrast can be used for researching dry eye disease .

HY-152003S

Ganglioside GM2-d3 ammonium

Ganglioside GM2-d₃ (ammonium) is the deuterium labeled Ganglioside GM2 (HY-148385). Ganglioside GM2 is a human tumor antigen predominantly found in human tumor cells and fetal brain tissue. As a sialylated glycosphingolipid, Ganglioside GM2 is involved in processes such as cell signaling, adhesion, and motility. Ganglioside GM2 abnormal expression and accumulation are associated with tumors and neurodegenerative disorders. Ganglioside GM2 promotes tumor cell migration and invasion by directly binding to the integrin β1 receptor, activating the FAK/Src/Erk-MAPK signaling pathway, and inducing actin cytoskeleton remodeling .

L-Cystine-13C6,15N2

L-Cystine- ¹³C₆, ¹⁵N₂ is the ¹³C- and ¹⁵N-labeled L-Cystine (HY-N0394). L-Cystine is an orally active extracellular form of L-Cysteine (HY-Y0337), occurring in proteins of plants and animals. L-Cystine elevates Nrf2 protein expression and activates Nrf2 transcription factor. L-cystine reduces ROS generation and protects against oxidant- or Doxorubicin (HY-15142A)-induced apoptosis. L-Cystine combined with L-theanine (HY-15121) enhances the production of antigen-specific IgG by increasing glutathione (GSH) levels and T helper 2 (Th2) mediated responses in mice. L-Cystine is promising for research of cystinuria and kidney stones.
