Biological Activity

In Vitro:

Cell Line
Concentration Treated Time Description References
H9c2 cells 50 μmol/L 1 hour To evaluate H2O2-induced apoptosis and cell death, results showed that HO-1 TG myocytes were resistant to H2O2-induced cell death Circulation. 2010 May 4;121(17):1912-25.
Escherichia coli K-12 strain MG1655 60 μM 1 hour To evaluate the antimicrobial activity of CORM-3 against E. coli and its intracellular Ru accumulation. Results showed that CORM-3 significantly inhibited bacterial growth and increased intracellular Ru levels, directly correlating with cytotoxicity. Redox Biol. 2018 Sep;18:114-123.
Cardiomyocytes 100 µM 30 minutes To evaluate the effect of CORM-3 on mitochondrial membrane potential, results showed that CORM-3 pretreatment attenuated PAO-induced MPT Circulation. 2010 May 4;121(17):1912-25.
Human colon carcinoma cell line RKO 25 μM 1 hour To assess the cytotoxicity of CORM-3 on mammalian cells and its intracellular Ru accumulation. Results demonstrated that CORM-3 significantly reduced cell survival, correlating with intracellular Ru accumulation levels. Redox Biol. 2018 Sep;18:114-123.
Primary neurons 100 μM 3 hours pretreatment To evaluate the effect of CORM-3 on neurons under oxygen-glucose deprivation (OGD) conditions, results showed that CORM-3 inhibited OGD-induced IRE1 phosphorylation and inflammasome expression EBioMedicine. 2019 Feb;40:643-654.

Administration Dosage Frequency Description References
Rats Spinal cord injury model 8 mg/kg Not used CORM-3 alleviates neuron death by inhibiting the activation of caspase-1 and caspase-11 and the release of pro-inflammatory factors IL-1β and IL-18 J Adv Res. 2020 Aug 18;28:97-109
Mice Myocardial infarction model Intraperitoneal injection 40 mg/kg Once daily for 24 days To evaluate the effect of CORM-3 on post-infarction LV remodeling, results showed that CORM-3 treatment attenuated LV dilatation and dysfunction Circulation. 2010 May 4;121(17):1912-25.
Sprague-Dawley rats Spinal cord injury model Tail vein injection 8 mg/kg/day Once daily until sacrifice To evaluate the effect of CORM-3 on neuron death and motor functional recovery after spinal cord injury, results showed that CORM-3 alleviated neuron death and improved motor functional recovery EBioMedicine. 2019 Feb;40:643-654.
C57BL/6J mice Chronic ethanol-induced liver injury model Intraperitoneal injection 3 mg/kg Once daily for 5 days To evaluate the therapeutic effect of CORM-A1 on ethanol-induced liver injury, it was found that CORM-A1 reduced ethanol-induced increases in AST and ALT, decreased expression of inflammatory cytokines TNF α, IL6 and CXCL10, and reduced accumulation of the hepatocyte death marker M30 and expression of RIP3. J Hepatol. 2014 Nov;61(5):1029-37.

Dissolving Methods
Please choose the appropriate dissolution scheme according to your animal administration guide.For the following dissolution schemes, clear stock solution should be prepared according to in vitro experiments, and then cosolvent should be added in turn:

in order to ensure the reliability of the experimental results, the clarified stock solution can be properly preserved according to the storage conditions; The working fluid for in vivo experiment is recommended to be prepared now and used on the same day;

The percentage shown in front of the following solvent refers to the volume ratio of the solvent in the final solution; If precipitation or precipitation occurs in the preparation process, it can be assisted by heating and/or ultrasound.
