生物活性

RI-1 is a RAD51 inhibitor, with IC50s ranging from 5 to 30 μM. RI-1 binds covalently to the surface of RAD51 protein at cysteine 319. RI-1 inactivates RAD51 by directly binding to a protein surface that serves as an interface between protein subunits in RAD51 filaments. RI-1 can disrupt homologous recombination in human cells[1].

IC50 & Target

IC50: 5-30 μM (RAD51)[1]

体外研究
(In Vitro)

RI-1 (1-50 µM; 24 h) specifically inhibits homologous recombination (HR) in U2OS cells and stimulates single-strand annealing (SSA) in HEK293 cells[1].
RI-1 (5-20 µM; 30 min) inhibits HsRAD51 in a concentration-dependent manner[1].
RI-1 (20 µM; 8 h) disrupts the formation of RAD51 foci after DNA damage in immortalized human fibroblasts[1].
RI-1 (15-25 µM; 24 h) sensitizes human cancer cells (HeLa, MCF-7 and U2OS) to cross-linking chemotherapy[1].

请根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:

——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用; 以下溶剂前显示的百
分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 1.

    请依序添加每种溶剂: 10% DMSO    90% corn oil

    Solubility: ≥ 2.5 mg/mL (6.91 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (6.91 mM,饱和度未知) 的澄清溶液,此方案不适用于实验周期在半个月以上的实验。

    以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。
