5-Bromouridine (CAS 957-75-5)  is a brominated analog of the nucleoside uridine. It can be incorporated into RNA and subsequently detected by antibodies against bromodeoxyuridine. 5-Bromouridine decreases the viability of HL-60 and MOLT-4 cells (LC50s = 10 and 20 μM, respectively). It induces apoptosis and halts the cell cycle at the S phase in HL-60 cells. It is photoreactive, and UV irradiation has been used to cross-link RNA containing 5-bromouridine to proteins in the study of of RNA-protein interactions. 5-Bromouridine can also be incorporated into RNA using 5-bromouridine 5’-triphosphate.
