Biological Activity

OBE022 is a potent, highly selective, orally active antagonist of the contractile PGF2α prostaglandin receptor with Kb of 5.9 nM, shows no activity for other human PG receptors subtypes; inhibits spontaneous, oxytocin- and PGF2α-induced human myometrial contractions alone and is more effective in combination with atosiban or nifedipine; reduces spontaneous contractions in near-term pregnant rat, OBE022 delayed RU486-induced parturition and exerted synergistic effects in combination with nifedipine; exhibits potent tocolytic effects on human tissues ex vivo and animal models in vivo without causing the adverse fetal side effects.
