Cardiovascular effects of lysophosphatidic acid and its structural analogs in rats
A Tokumura et al. J Pharmacol Exp Ther. 1981 Oct.
Abstract
Injection of lysophosphatidic acid into anesthetized rats induced immediate hypertension, the effect depending on the structure of the sn-1-acyl moiety of the molecule. A hydroxyl group at the sn-2-position was not necessary, but a wedgeshaped structure was suitable for hypertensive activity. Most lysophospholipids with a chemical group attached to the phosphate portion had only weak hypotensive effects, but the sn-2-acetylated analogs of these depressor lysophospholipids elicited a hypotension at much lower doses. The durations of the hypotensions evoked by the sn-2-acetylated choline phospholipids were longer than those produced by 1-palmitoyl-2-acetoyl-sn-glycerol-3-phosphorylmethanol, ethanol and propanol.
