High-Throughput Permeability pH Profile and High-Throughput Alkane/Water log P with Artificial Membranes

Wohnsland, Frank, Faller, Bernard·2001·Journal of Medicinal Chemistry

Abstract

This study reports on a novel, high-throughput assay, designed to predict passive, transcellular permeability in early drug discovery. The assay is carried out in 96-well microtiterplates and measures the ability of compounds to diffuse from a donor to an acceptor compartment which are separated by a 9-10 microm hexadecane liquid layer. A set of 32 well-characterized, chemically diverse drugs was used to validate the method. The permeability values derived from the flux factors between donor and acceptor compartments show a good correlation with gastrointestinal absorption in humans. For comparison, correlations based on experimental or calculated octanol/water distribution coefficients (log D(o/w,6.8)) were significantly lower. In addition, this simple and robust assay allows determination of pH permeability profiles, critical information to predict gastrointestinal absorption of ionizable drugs and difficult to obtain from cell culture experiments. Correction for the unstirred water layer effect allows to differentiate between effective and intrinsic membrane permeability and opens up the dynamic range of the method. In addition, alkane/water partition coefficients can be derived from intrinsic membrane permeabilities, making this assay the first high-throughput method able to measure alkane/water log P in the microtiterplate format.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
