Description

PF-3274167 (Cligosiban) is a potent, selective, brain penetrant oxytocin receptor antagonist. Cligosiban interrupts the expulsion phase of ejaculation by reducing the normal bulbospongiosum burst pattern and reducing the expulsions that accompany bursts. Cligosiban represents a promising compound to test the clinical hypothesis that antagonism of central oxytocin receptors may be of therapeutic benefit in the treatment of premature ejaculation. [11C]PF-3274167 is not a suitable tracer for imaging of OTR in rat brain, probably because of a too low affinity for this receptor in addition to a poor brain penetration. PF-3274167 had been in phase I clinical trial for the treatment of sexual function disorders and urinary incontinence. However, this research has been discontinued.
