Table 3. Solubility and PAMPA Permeability Profiles of Selected Series I–VI Analogsc.
Multiscreen filter plates (Millipore), 24 h agitation, pH 7.4, 25 °C.
Pe measures the rate at which a molecule crosses a membrane or lipid bilayer. Multiscreen-IP PAMPA assay donor/receiver plates (Millipore), 1% lecithin in dodecane as barrier, 18 h agitation, pH 7.4, 25 °C. Pe of propranolol determined under similar conditions was 11.9 ± 0.8.
Solubility and Pe values are mean (SD) from 3 separate determinations.
