生物活性/药理作用

Hydroxyurea has dose-dependent synergistic activity with cisplatin in vitro. In vivo Hydroxyurea showed activity in combination with cisplatin against the LX-1 and CALU-6 human lung xenografts, but minimal activity was seen with the NCI-H460 or NCI-H520 xenografts. Hydroxyurea was synergistic with cisplatin in the Lewis lung murine xenograft. Sequential exposure to Hydroxyurea 4 hours before cisplatin produced the greatest interaction.

Hydroxyurea is 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.
