Alprostadil functions as a prostanoid receptor ligand, exhibiting binding affinities Kis of 1.1 nM, 2.1 nM, 10 nM, 33 nM, and 36 nM for murine EP3, EP4, EP2, IP, and EP1, correspondingly. Alprostadil can inhibit platelet aggregation and thrombin A2 production, and has diuretic and renal function protection [1-3].
Alprostadil(0.1-50 ng/ml; 8-26h) causes an upregulation of eNOS and VEGF protein and mRNA expression in HUVEC and decreases HIF-1alpha[4]. Alprostadil (10 ng/mL; 24h) reduces apoptosis and improves the homing of mesenchymal stem cells in pulmonary arterial hypertension by regulating hypoxia-inducible factor 1 alpha[5].
Alprostadil(5 ug/kg; i.p) can reduce pancreatic tissue damage, delay pancreatic cell apoptosis, and reduce inflammation and anti-oxidative stress by inhibiting the JAK2/STAT3 signal pathway, thus protecting the pancreas in acute pancreatitis rat model[6]. Alprostadil (0.3125, 0.625, and 1.25 mg/kg/d; i.p) attenuates AngII-induced cardiac hypertrophy via E-prostanoid (EP) 3 receptor activation and Netrin-1upregulation[7].
