Abstract
The effects of prostacyclin (PGI2) and stable derivatives of PGI2, such as isocarbacyclin (PGI2 deriv. (A] and isocarbacyclin methyl ester (PGI2 deriv. (B)), on junctional transport of fluorescein dextran (FD) through cultured porcine arterial endothelial cells were investigated. These PGI2S inhibited the transcellular transport dose-dependently. After the elimination of PGI2, its inhibitory effect persisted for at least 1 hr. A good correlation was found between increase of cAMP and the potency of inhibition. Increase of cAMP after PGI2 treatment seemed to be involved in the inhibition of FD transport.
