Biological Activity

In Vitro:

Cell Line
Concentration Treated Time Description References
Human embryonic kidney (HEK) 293 cells 13.4 µM 10 minutes The hKIR2.1 current was significantly inhibited by W-7 at test potentials of -120 to -80 mV and -60 to -10 mV. Br J Pharmacol. 2010 Oct;161(4):872-84
Human embryonic kidney (HEK) 293 cells 6.5 µM 10 minutes W-7 significantly suppressed activity of hKv1.5 channels at test potentials of 0 to +50 mV. Br J Pharmacol. 2010 Oct;161(4):872-84
Human embryonic kidney (HEK) 293 cells 3.5 µM 10 minutes W-7 decreased the hERG current (IhERG) in a concentration-dependent manner (IC50: 3.5 μM), and the inhibition was more significant at depolarization potentials between +10 and +60 mV. Br J Pharmacol. 2010 Oct;161(4):872-84
Human adherent monocytes 5 µM and 10 µM 12 hours To investigate the effect of W-7 on PT- and LPS-induced IL-1 production. Results showed that W-7 significantly suppressed PT-induced IL-1 production but had no significant effect on LPS-induced IL-1 production. Immunology. 1989 Jun;67(2):210-5
Vascular smooth muscle cells 100 µM 30 minutes Inhibited AngII-induced ERK1/2 phosphorylation Biochem Pharmacol. 2018 Jun;152:187-200
Cochlear outer hair cells (OHCs) 150 µM 30–60 minutes W-7 shifted the voltage sensitivity of the membrane capacitance in the depolarised direction J Physiol. 2001 Mar 15;531(Pt 3):667-76

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.
