Summary
Osalmid is a ribonucleotide reductase small subunit M2 ( RRM2 ) targeting compound; suppresses ribonucleotide reductase activity with an IC 50 of 8.23 μM.
IC50 & Target
IC50: 8.23 μM (ribonucleotide reductase) [1]
In Vitro
Osalmid is identified as a potential ribonucleotide reductase small subunit M2 (RRM2) compound. Osalmid is 10-fold more active in inhibiting ribonucleotide reductase (RR) activity than hydroxyurea, and significantly inhibits HBV DNA and cccDNA synthesis in HepG2.2.15 cells in a time- and dose-dependent manner. After treatment for 8 days with Osalmid, the EC 50 for HBV DNA inhibition are 11.1 μM for culture supernatant and 16.5 μM for cells. Osalmid suppresses RR activity in a concentration-dependent manner, with an IC 50 of 8.23 μM. Osalmid is shown to possess potent activity against a 3TC-resistant HBV strain, suggesting utility in treating drug-resistant HBV infections [1] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Osalmid reduces RR activity and HBV replication in HBV-transgenic mice and shows a synergistic efficacy with 3TC without significant toxicity. Oral dosing of osalmid at 400 mg/kg/d results in a time-dependent inhibition of HBV DNA replication. After treatment for 4 weeks, osalmid suppresses HBV DNA replication by about 40-45% as compared to the control in mouse sera and liver tissues [1] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
