This product is intended for research and analytical applications. 2-Deoxy-2-sulfoamino-D-glucose sodium (D-Glucosamine-2-N-sulfate sodium) is an endogenous metabolite. The main regulatory mechanism of 2-Deoxy-2-sulfoamino-D-glucose sodium involves the interaction of sulfuric acid groups with biomolecules. Sulfate groups can influence the charge density and configuration of polysaccharides, thereby regulating their ability to bind to proteins such as antithrombin. This combination can enhance the activity of antithrombin, which in turn inhibits key enzymes in the blood clotting process to achieve anti-clotting effects. 2-Deoxy-2-sulfoamino-D-glucose sodium can be used to study the selective removal of n-sulfate groups from Heparin (HY-17567) which has important implications for understanding the biological activity of heparin and developing related drugs . |

In Vitro: 3-Indolepropionic acid is shown to be a powerful antioxidant and has potential in the treatment for Alzheimer’s disease . 3-Indolepropionic acid is a more potent scavenger of hydroxyl radicals than melatonin. Similar to melatonin but unlike other antioxidants, 3-Indolepropionic acid scavenges radicals without subsequently generating reactive and pro-oxidant intermediate compounds . It is also suggested that indolepropionic acid, a gut microbiota-produced metabolite, is a potential biomarker for the development of type 2 diabetes (T2D) that may mediate its protective effect by preservation of β-cell function . |

                                                | Kidneys are one of the vital organs in the human body. Due to their exposure to higher concentrations of circulating drugs or metabolites, they are highly susceptible to drug-induced renal injury (DIRI). According to statistics, drug-induced kidney injury accounts for approximately 20% of nephrotoxicity reports and can lead to acute kidney injury (AKI), chronic kidney disease (CKD), or even end-stage renal disease (ESRD). Early detection of drug nephrotoxicity is crucial for preventing irreversible kidney damage. Research into its mechanisms can help optimize clinical medication by adjusting dosages or avoiding combinations of nephrotoxic drugs. Additionally, predicting drug-induced nephrotoxicity in early drug development can reduce the risk of late-stage R&D failure.   MCE offers 152 nephrotoxicity compounds that have been clearly reported by the FDA to be associated with kidney injury. This library can be used for studying molecular mechanisms of nephrotoxicity or developing novel biomarkers.  |

This product is intended for research and analytical applications. Urolithin D (3,4,8,9-Tetrahydroxy urolithin) is a colonic metabolite of Ellagitannins and a competitive, reversible, and selective antagonist of the EphA receptor. Urolithin D inhibits EphA2-ephrin-A1 binding with an IC50 of 0.9 μM. Urolithin D is also a potent antioxidant that scavenges free radicals and repairs oxidized DNA damage. Additionally, Urolithin D suppresses triglyceride accumulation and promotes fatty acid oxidation by activating the AMPK signaling pathway. Urolithin D can be used for research on tumors, metabolic, and inflammatory diseases . |

This product is intended for research and analytical applications. 2-Deoxy-2-sulfoamino-D-glucose sodium (D-Glucosamine-2-N-sulfate sodium) is an endogenous metabolite. The main regulatory mechanism of 2-Deoxy-2-sulfoamino-D-glucose sodium involves the interaction of sulfuric acid groups with biomolecules. Sulfate groups can influence the charge density and configuration of polysaccharides, thereby regulating their ability to bind to proteins such as antithrombin. This combination can enhance the activity of antithrombin, which in turn inhibits key enzymes in the blood clotting process to achieve anti-clotting effects. 2-Deoxy-2-sulfoamino-D-glucose sodium can be used to study the selective removal of n-sulfate groups from Heparin (HY-17567) which has important implications for understanding the biological activity of heparin and developing related drugs . |

O-phospho-L-serine is a competitive inhibitor of serine racemase and phagocytosis. O-phospho-L-serine inhibits the enzymatic reaction by competing with the active site of serine racemase, thereby affecting the production of D-serine. O-phospho-L-serine also mimics the phosphatidylserine head group, binds to the phosphatidylserine receptor, interferes with phagocytic signal transduction, and partially blocks the phagocytosis of apoptotic cells by cells. O-phospho-L-serin can be used in the research of retinal regeneration, bone repair, and insect growth and development  . |

In Vitro: 3-Indolepropionic acid is shown to be a powerful antioxidant and has potential in the treatment for Alzheimer’s disease . 3-Indolepropionic acid is a more potent scavenger of hydroxyl radicals than melatonin. Similar to melatonin but unlike other antioxidants, 3-Indolepropionic acid scavenges radicals without subsequently generating reactive and pro-oxidant intermediate compounds . It is also suggested that indolepropionic acid, a gut microbiota-produced metabolite, is a potential biomarker for the development of type 2 diabetes (T2D) that may mediate its protective effect by preservation of β-cell function . |
