U-46619是一种PGH2类似物,可以用作血栓烷A2(TP)受体激动剂,影响人类血管平滑肌的促有丝分裂生长。U 46619是稳定的血栓烷A2模拟物,是H2内过氧化物前列腺素的类似物,用作血管收缩剂和血栓烷受体激动剂。
U-46619 (9,11-Methanoepoxy PGH2) 是一种稳定的血栓素 A2 (TXA2) 的类似物,也是一种有效的 TXA2 激动剂。TXA2
U-46619 (1 nM-10 μM) causes platelets shape change and aggregation in a concentration-dependent manner, and with EC
50
s of 0.58 μM and 0.013 μM for aggregation and shape change, respectively.
U-46619 (10 nM-10 μM) increases internal Ca
2+
concentration ([Ca
2+
]i) and activates phosphoinositide (PI) hydrolysis in a concentration-dependent manner with a similar concentration-dependency.
U-46619 (3 nM-10 μM) also activates GTPase concentration-dependently in the membranes derived from platelets.
U-46619 improves the differentiation efficiency of human induced pluripotent stem cells into endothelial cells by activating both p38MAPK and ERK1/2 signaling pathways.
U-46619 (5 μg/kg; i.v.) increases blood pressure in male spontaneously hypertensive rats (SHR).
