Meccanismo d'azione (Mechanism of Action)

Targets/IC50/Ki
ribonucleoside diphosphate reductase
In vitro
hydroxyurea can inhibit HIV-1 replication. In vitro experiments have shown that the 90% inhibitory concentration (IC90) of this compound for laboratory strains of HIV-1 in activated PBMC is 0.4 mM. It was also found to be synergistic with the nucleoside reverse transcriptase inhibitor didanosine and to inhibit HIV-1 replication in activated PBMC; this inhibition may be due to a reduction in deoxynucleoside triphosphate pool sizes. This chemical has been shown to sensitize didanosine-resistant mutants. It has demonstrated activity in the treatment of sickle cell anemia by increasing the production of fetal hemoglobin, which reduces hemolysis in patients with this disease. This agent exerts its cytostatic effect through inhibition of ribonucleotide reductase—the rate-limiting enzyme responsible for the conversion of ribonucleotides to deoxyribonucleotides, which are essential for DNA synthesis. As a result, cellular division is arrested in the S phase.
