Biological Activity
BQ-123 is an ETA endothelin receptor antagonist (Ki values are 1.4 and 1500 nM at ETA and ETB receptors respectively) . 1) Reduces ischemia-induced ventricular arrhythmias in a rat model.2) BQ-123 prevents LPS-induced preterm birth in mice via the induction of uterine and placental IL-10.3) The reference for animal injections is 6.7 mg/kg. 4) BQ-123 decreased IL-1β and TNFα in the placenta while also decreasing transcription of ET-1 in the uterus.
