Dooku1
Based on 16 publication(s) in Google Scholar
Dooku1 is a reversibly Yoda1 antagonist with IC50 value of 1.3 μM and 1.5 μM for 2 μM Yoda1-induced Ca2+ entry HEK 293 cells and HUVECs, respectively. Dooku1 can disrupt Yoda1-induced Piezo1 channel activity and inhibit Yoda1-induced relaxation of aorta. Dooku1 can be used for vascular physiology and disease research.

Dooku1 inhibits shear-stress-induced NLRP3 inflammasome activation in iBMDMs. (A) A representative imaging panel is shown above for ASC−CFP expressed iBMDMs primed LPS for 4 h followed by treatments of 10 or 50 μM Dooku1 for 2 h and 50 dyn/cm2 shear stress treatment for 30 min. LPS only controls were also performed according to aforementioned time points. NucRed stains living cell nuclei in blue, ASC−CFP specks indicating inflammasome activation are shown in cyan, and propidium iodide (PI) shows dead cell nuclei in red.
