Dooku1, a reversible Yoda1 antagonist, has a concentration-dependent inhibitory effect against Yoda1-induced Ca2+ entry in HUVECs, acting with an IC50 of 1.49μM. Dooku1 can antagonize Yoda1‐evoked activation of Piezo1 and aortic relaxation and be used for research related to hypertensive nephropathy[1].
Dooku1 pretreatment (5μM) in rat cauda epididymal epithelial cells significantly suppressed the Yoda1-stimulated Ca2+ response. The Yoda1-stimulated Ca2+ response was abolished when ambient Ca2+ was removed [2]. Dooku1 inhibited 2μM Yoda1‐induced Ca2+‐entry with IC50 of 1.3μM in HEK 293 cells [1].
Dooku1 treatment (10 mg/kg) significantly increased the right turn percentage 72 hours after intracerebral hemorrhage (ICH) among Male adult C57BL/6 mice in the corner turn test. Compared with the ICH +vehicle group, Dooku1 treatment (10 mg/kg) significantly decreased the brain water content at 24 and 72 hours after ICH. A moderate dose (10 mg/kg) of the Piezo1 antagonist Dooku1 could relieve neurological impairment and myelin damage among C57BL/6 mice[3].
