描述 | Selexipag (NS-304) is an orally administered, long-acting prodrug that acts as an IP receptor agonist. Its active metabolite, MRE-269, exhibits high selectivity for the IP receptor. Selexipag (NS-304) concentration-dependently inhibits the binding of [3H]Iloprost to both human and rat IP receptors, with Ki values of 260 nM and 2100 nM, respectively. Treatment with Selexipag (NS-304) increases intracellular cAMP levels in hIP-CHO cells in a concentration-dependent manner, with an EC50 of 177nM. Additionally, Selexipag (NS-304) inhibits platelet aggregation in humans and monkeys, with IC50 values of 5.5 μM and 3.4 μM, respectively, while exhibiting no inhibition in dogs (IC50 >100 μM) [1]. |
Animal study | After oral administration of NS-304, the maximum plasma concentration (Cmax) of MRE-269 is 1.1 μg/mL in rats and 9.0 μg/mL in dogs. In anesthetized rats, intraduodenal administration of Selexipag (NS-304) at doses of 1 or 3 mg/kg leads to a dose-dependent increase in splanchnic blood flow (FSBF) for over 4 hours. Notably, the 3 mg/kg dose of Selexipag (NS-304) induces a sustained elevation in FSBF, with a maximal increase of 93% observed 1 hour post-administration [1]. |
