U-46619 BiologicalActivity

Description	U-46619 (9,11-Methanoepoxy PGH2) is a stable analogue of thromboxane A2 (TXA2) and acts as a potent TXA2 agonist[1].
Related Catalog	Research Areas >>Cardiovascular DiseaseSignaling Pathways >>GPCR/G Protein >>Prostaglandin Receptor
Target	TXA2[1]
In Vitro	U-46619 (1 nM-10 μM) causes platelets shape change and aggregation in a concentration-dependent manner, and with EC50s of 0.58 μM and 0.013 μM for aggregation and shape change, respectively[1]. U-46619 (10 nM-10 μM) increases internal Ca2+ concentration ([Ca2+]i) and activates phosphoinositide (PI) hydrolysis in a concentration-dependent manner with a similar concentration-dependency[1]. U-46619 (3 nM-10 μM) also activates GTPase concentration-dependently in the membranes derived from platelets[1]. U-46619 improves the differentiation efficiency of human induced pluripotent stem cells into endothelial cells by activating both p38MAPK and ERK1/2 signaling pathways[2].
In Vivo	U-46619 (5 μg/kg; i.v.) increases blood pressure in male spontaneously hypertensive rats (SHR)[3]. Animal Model: 12-15 weeks-old male and female SHR[2] Dosage: 5 μg/kg Administration: Intravenous injection Result: Induceed a significant increase of MABP after 1 min in male SHR.
