A monohydroxyl-substituted urea (hydroxycarbamate) antimetabolite. Hydroxyurea selectively inhibits ribonucleoside diphosphate reductase, an enzyme required to convert ribonucleoside diphosphates into deoxyribonucleoside diphosphates, thereby preventing cells from leaving the G1/S phase of the cell cycle. This agent also exhibits radiosensitizing activity by maintaining cells in the radiation-sensitive G1 phase and interfering with DNA repair. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
