Biological Activity

Description 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.
Targets
cGAS/dsDNA complex [1]
(Cell-free assay)		 cGAS [1]
(Cell-free assay)
36.2 nM(Kd) 700 nM
In vitro
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]
Cell Research Cell lines Mouse Embryonic Fibroblasts (MEFs)
Concentrations 1 μM
Incubation Time 3, 7, 40 days
Method

MEFs are exposed with or without STINGi or cGASi to CDT 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.
In Vivo
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.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
