Djenkolic acid | 98.0% | 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-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. | ||||||||||||||||||||
