U 46619 (CAS 56985-40-1): R&D Systems
Catalog Number: 1932
Alternate Names: 9,11-Dideoxy-9a,11a-methanoepoxy prostaglandin F2a
Chemical Name: (5Z)-7-[(1R,4S,5S,6R)-6-[(1E,3S)-3-Hydroxy-1-octenyl]-2-oxabicyclo[2.2.1]hept-5-yl]-5-heptenoic acid
Biological Activity
PGH2 (TXA2) analog that is a potent and stable thromboxane A2 (TP) receptor agonist (EC50 = 0.035 μM). Potently stimulates TP receptor-mediated, but not other prostaglandin receptor-mediated responses in various in vitro preparations. Activates ERK-1 and ERK-2 in HEK 293 cells expressing TPα and TPβ receptors.
