Inhibition of binedaline binding to human alpha 1-acid glycoprotein and other serum proteins by chlorpromazine, imipramine, and propranolol.
Binedaline (1-[[2-(dimethylamino)ethyl]methylamino]- 3-phenylindole) binding to human alpha 1-acid glycoprotein and other serum proteins was studied in the presence of three basic compounds: chlorpromazine, propranolol, and imipramine. In serum, at therapeutic concentrations, binedaline binding was not modified by the presence of these three compounds, nor did binedaline inhibit the binding of these compounds. With isolated alpha 1-acid glycoprotein, the four drugs exhibited competitive inhibition indicating that they share a common binding site on this protein.
