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	2% DMSO 1 40% PEG 300 2 5%Tween80 3 53%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。	1.000mg/ml (2.41mM)	Taking the 1 mL working solution as an example, add 20 μL of 50 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 530 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	2%DMSO 1 98%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。	0.500mg/ml (1.20mM)	Taking the 1 mL working solution as an example, add 20 μL of 25 mg/ml clear DMSO stock solution to 980 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	RU.521 (RU320521) is an active, potent and selective inhibitor of cyclic GMP-AMP synthase (cGAS) that inhibits the cGAS-mediated signaling with IC50 of 700 nM. RU.521 binds to the cGAS/dsDNA complex with Kd of 36.2 nM.
in vitro	RU.521, a cGAS inhibitor, impares the overexpression of interferon-stimulated genes (ISGs) in response to cytolethal distending toxin (CDT), confirming the crucial role of cGAS-STING axis in CDT-induced type I IFN signaling.^[2]
in vivo	RU.521 alleviated the inflammatory response and alleviated the damage induced by oxidative stress, leading to cardiac protection via increased Sirt3 expression in the hearts of mice with sepsis.

プロトコル(参考用のみ)

細胞アッセイ	細胞株	Mouse Embryonic Fibroblasts (MEFs)
	濃度	1 μM
	反応時間	3, 7, 40 days
	実験の流れ	MEFs are exposed with or without STINGi or cGASi to this compound 7.5 ng/ml for the indicated times or to the H153A CDT mutant for 40 days. The mRNA level of the indicated genes is analyzed by RT-qPCR and the IL-6 or TNFα production in the culture supernatant are determined by ELISA. For ELISA assays, a 2 days exposure to LPS 100 ng/ml is used as positive control.
