Hydroxyurea by Sanis Health
Hydroxyurea by Sanis Health Uses, Dosage, Side Effects, Food Interaction and all others data.
Hydroxyurea by Sanis Health is converted to a free radical nitroxide (NO) in vivo, and transported by diffusion into cells where it quenches the tyrosyl free radical at the active site of the M2 protein subunit of ribonucleotide reductase, inactivating the enzyme. The entire replicase complex, including ribonucleotide reductase, is inactivated and DNA synthesis is selectively inhibited, producing cell death in S phase and synchronization of the fraction of cells that survive. Repair of DNA damaged by chemicals or irradiation is also inhibited by hydroxyurea, offering potential synergy between hydroxyurea and radiation or alkylating agents. Hydroxyurea by Sanis Health also increases the level of fetal hemoglobin, leading to a reduction in the incidence of vasoocclusive crises in sickle cell anemia. Levels of fetal hemoglobin increase in response to activation of soluble guanylyl cyclase (sGC) by hydroxyurea-derived NO.
Hydroxyurea by Sanis Health has dose-dependent synergistic activity with cisplatin in vitro. In vivo Hydroxyurea by Sanis Health 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 by Sanis Health was synergistic with cisplatin in the Lewis lung murine xenograft. Sequential exposure to Hydroxyurea by Sanis Health 4 hours before cisplatin produced the greatest interaction.
