体内（毎回新しく調製した物を用意してください）

Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	3.300mg/ml (9.72mM)	Taking the 1 mL working solution as an example, add 50 μL of 66 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	1.600mg/ml (4.71mM)	Taking the 1 mL working solution as an example, add 50 μL of 32 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	B02はヒトRAD51の低分子阻害剤で、IC50は27.4 μMですが、その大腸菌ホモログRecAは阻害しません（IC50 > 250 μM）。
in vitro	B02 is a specific inhibitor of human RAD51 recombinase, blocks HR repair in human embryonic kidney (HEK) and breast cancer cells and increases their sensitivity to a wide range of DNA damaging agents. Also, this compound enhances DNA damage and apoptosis induced by decitabine in MM cells. It shows high specificity for RAD51 and does not significantly inhibit RAD54 in the range of concentrations from 0 to 200 μM. This chemical shows biological effect in human and mouse cells. In human embryonic kidney (HEK) cells, it disrupts RAD51 foci formation in response to DNA damage and inhibited DSB repair and DSB-dependent HR. It can also increase the sensitivity of cancer cells to chemotherapeutic DNA damaging agents.
in vivo	B02 significantly increases the anti-tumor activity of cisplatin in vivo. This compound is tolerated by mice at doses up to 50 mg/kg without obvious body weight loss. No detectable morphological changes induced by this chemical in kidneys and livers, main organs for detoxification are found.

細胞アッセイ	細胞株	The human MM cell lines NCI-H929 (H929), RPMI 8226, ARP-1, U266 and MM.1S cells
	濃度	10 μM
	反応時間	1 h
	実験の流れ	Proliferation of MM-cell lines is monitored by the WST-1 colorimetric cell-count assay. MM cell lines are seeded in 96-well plates at ~8000 cells/well. The cells are treated with or without this compound (10 μM) for 1 h, followed by treatment with vehicle (DMSO) or DOX (20-160 nM) for 72 h. WST-1 reagent is added to the culture medium in each well at a 1:10 ratio, and incubation continues at 37°C for 4 h. Relative cell number is estimated from absorbance at 450 nm using a spectrophotometer.
