BBB penetration = [brain]/[blood].
Caco-2 cells derived from human colon adenocarcinoma, possessing multiple drug transport pathways through intestinal epithelium.
HIA (human intestinal absorption), the sum of absorption and bioavailability evaluated from ratio of excretion in urine, bile, and feces.
MDCK cell system is used as a tool for rapid permeability screening.
% of drug that binds to plasma protein.
In vitro Ames test by metabolic and nonmetabolic activated TA100 and TA1535 strains collected from rat liver homogenate.
