[The ectophosphatase activity of cultured endothelial cells of calf aorta and the effect of drugs on ecto-ATPase].
Cultivated endothelial cells of calf aorta (line BKEz-7) possess an effective ectophosphatase system (enzyme activities: ATPase 38.0 +/- 10.2; ADPase 9.2 +/- 4.2; 5'-nucleotidase 4.1 +/- 2.6 fmol/cell.min). Drugs with central depressive activity such as promazine, chlorpromazine, and meprobamate inhibit the activity of the ecto-ATPase. A possible connection between the inhibitory activity on the ecto-ATPase and their central depressive effects is discussed.
