General description

5-Aminoorotic acid forms complexes with cerium (III), lanthanum (III) and neodymium (III). It reacts with dianhydride of ethylenedinitrilotetraacetic acid in dry DMF or DMSO to yield functionalized dicarboxamide derivatives.

Application

5-Aminoorotic acid was used as an internal standard during the electrochemical determination of orotic acid.

The loss-of-function mutation of fumarate hydratase (FH) is a driver of hereditary leiomyomatosis and renal cell carcinoma (HLRCC). Fumarate accumulation results in activation of stress-related mechanisms leading to upregulation of cell survival-related genes. To better understand how cells compensate for
