CAS 603-45-2

Aurin

Description:

Aurin, with the CAS number 603-45-2, is an organic compound classified as a dye, specifically a type of azo dye. It is characterized by its vibrant yellow to orange color, which is attributed to the presence of azo (-N=N-) functional groups in its molecular structure. Aurin is soluble in organic solvents and exhibits limited solubility in water, making it useful in various applications, including textiles and biological staining. The compound is known for its stability under normal conditions, although it may degrade under extreme pH or light exposure. Aurin can also exhibit fluorescence, which enhances its utility in certain analytical and imaging techniques. However, like many azo dyes, it may pose environmental and health risks, as some azo compounds can release carcinogenic amines upon degradation. Therefore, handling Aurin requires appropriate safety measures to mitigate potential hazards. Overall, Aurin serves as an important compound in both industrial and research settings, particularly in the fields of chemistry and biology.

Aurin

CAS: 603-45-2

Aurin is a novel drug that has been shown to be effective in the treatment of inflammatory bowel disease and congestive heart failure. Aurin is a prodrug that is metabolized by hydrolysis to aurin monophosphate (AMP), which inhibits the production of inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). AMP also inhibits the activity of many enzymes, including cyclooxygenase, lipoxygenase, phospholipases, and nitric oxide synthases. This inhibition leads to an anti-inflammatory effect by decreasing prostaglandins, leukotrienes, and nitric oxide production.
