title: Relationship of octanol/water partition coefficient and molecular weight to rat brain capillary permeability.
abstract: The rat brain capillary permeability coefficient was determined for 27 compounds. The relationship of permeability to octanol/water partition coefficient and molecular weight was found to be predictable for drugs with molecular weights less than 400.
