Drug-membrane interactions have recently been studied by immobilized artificial membrane (IAM) chromatography (Pidgeon, C.; et al. J. Med. Chem. 1995, 38,590-595. Ong, S.; et al. Anal. Chem. 1995, 67,755-762), and the molecular recognition properties of IAM surfaces toward drug bindhg/partitioning appear to be remarkably close to the molecular recognition properties of fluid membranes. The structural requirements of chromatography surfaces to ...
