title: [Interactions of some parasympatholytics and structurally similar drugs with bovine serum albumin].
abstract: The interactions of the parasympatholytic drugs adiphenin, adiphenin H and propanthelin and the structurally related compounds, diphenhydramine, D-propoxyphene and methadone with bovine serum albumin (BSA) are studied by equilibrium dialysis and ultracentrifugation. The results show that BSA has a few binding sites (n less than 10) for the mentioned drugs. The association between the compounds under study and BSA are relatively weak. The binding constants are in the range of 10(3) l/Mol.
