What is Tetrahydrouridine?
Description
Tetrahydrouridine is a competitive, reversible inhibitor of cytidine deaminase (Ki values = 54 and 240 nM for human and E. coli enzymes, respectively). Its use, alone or in combination with the DNA methyltransferase inhibitor 5-fluoro-2’-deoxycytidine, is being evaluated in animal models and clinical trials for diseases, including cancer and mitochondrial DNA depletion syndrome.
The Uses of Tetrahydrouridine
3,4,5,6-Tetrahydrouridine, is a derivative of Uridine (U829910). Tetrahydrouridine (THU), is a potent inhibitor of cytidine. It inhibits cell proliferation through cell cycle regulation regardless of cytidine deaminase expression levels deaminase (CDA), and thus can be used as a potential and promising treatment for tumors with highly expressed CDA.
What are the applications of Application
Tetrahydrouridine is a CDD inhibitor which may prevent growth of CDA-expressing tumors
