Djenkolic acid (Standard) | ≥98% | Djenkolic acid (Standard) is the analytical standard of Djenkolic acid (HY-125923). This product is intended for research and analytical applications. Djenkolic acid is a sulfur-containing amino acid. Djenkolic acid can be isolated from the djenkol beans of the Southeast Asian plant Archidendron jiringa. Djenkolic acid de-inhibits the SO42- uptake system in Pseudomonas fluorescens. Djenkolic acid causes supersaturation of the urinary system with djenkolic acid crystals, leading to urinary tract obstruction and acute kidney injury. | ||||||||||||||||||||

L-Cystine (Standard) | 96.68% | L-Cystine (Standard) is the analytical standard of L-Cystine. This product is intended for research and analytical applications. L-Cystine, the extracellular form of L-Cysteine (HY-Y0337), is a nutritionally dispensable semiessential sulfur-containing amino acid, occurring in proteins of plants and animals. L-Cystine induces Nrf2 protein elevation in a Keap1 (HY-P75897)-dependent manner and activates Nrf2 transcription factor. L-cystine can elicit cytoprotection by reducing ROS generation and protecting against oxidant- or doxorubicin-induced apoptosis. The reduced reabsorption of L-Cystine in renal tubules and its poor solubility in urine are the important causes of cystine precipitation and cystine crystal formation eventually leading to kidney stones. 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 cystinosis | ||||||||||||||||||||

L-Cystine-13C6,15N2 | 98.4% | 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. | ||||||||||||||||||||
