Descripción

Application

cis-Urocanic acid (cis-UCA) has been used:

• to study its protective effects on autoimmune encephalomyelitis[1]
• in sample preparation to study the distribution of skin chemical components by line illumination Raman microscopy technique in Line-focus illumination mode[2]
• as a standard to study the levels of cis-UCA and to check its effect on immune response in multiple sclerosis patients[3]

Biochem/physiol Actions

cis-Urocanic acid (cis-UCA) affects the immune cells of the body and is excreted in the urine due to photoisomerization.[3] It inhibits tumor immunity through photocarcinogenesis in mice. cis-Urocanic acid has been studied to prevent UV-radiation-induced DNA damage leading to skin cancer.[4]

cis-Urocanic acid, a 5-HT agonist, is a product of UV isomerization of trans-urocanic acid in skin, which leads to immunosuppression via activation of 5-HT_2A receptor.

Preparation Note

cis-Urocanic acid is soluble in water at a concentration that is greater than 10 mg/ml.
