Background:

GR 125743 is a selective 5-HT1B/1D receptor antagonist, with pKis of 8.85 and 8.31 for wild-type h5-HT1B and wild-type h5-HT1D, respectively. GR 125743 is used for the research of Parkinson's disease and cardiovascular diseases[1][2].

GR 125743 has a Kd of 0.61 nM for h5-HT1B[1].

GR 125743 (0.3 mg/kg; i.p.) produces significant decreases in extracellular 5-HT in the frontal cortex of the conscious guinea pig[2]. Animal Model: Male Dunkin Hartley guinea-pigs (350-450 g)[2]
