Use | The RI-1 is a RAD51 inhibitor with an IC50 of 5 to 30 μM. |
In vitro study | RI-1 by direct and specific destruction of HsRAD51 and inhibition of RAD51, the ability to form single-stranded DNA filaments, increase the sensitivity of cells to DNA damage. In addition, MCF-7 of all three cancer cell lines (HeLa cells, RI-1 and U2OS) produced single-dose toxicity alone with LD50 values in the 20-40 micron range. RI-1 reduced γ-H2AX foci in G2 cells and resulted in an increase in unrepaired DNA double-strand breaks 6 hours after irradiation. |
In vivo study | RI-1 (50 mg/kg; i.p. every 3 d for 30 d) significantly reduces triple negative breast cancer (TNBC) tumor growth in mice. Animal Model: Female BALB/c nude mice (6 weeks) bearing TNBC tumor Dosage: 50 mg/kg Administration: I.p. every 3 days for 30 days Result: Resulted in significant inhibition of tumor growth. Did not cause body weight loss significantly. |
