Method for simulating the interaction of chemical compounds with live organisms
First Claim
1. Method for determining the interaction of one or more active compounds administered to an organism, said method comprising the following steps:
- A) selecting at least one compound and analyzing the compound with respect to one or more characteristics selected from the group consisting of lipophilicity, solubility, protein binding, molecular weight, molecular volume, pKa value in the case of acids or bases, metabolic degradation rate and kinetic constants of the compound'"'"'s active transporters, B) selecting one or more anatomical and physiological compartments of the organism in question as follows;
i) in the case of mammals or insects, the selecting is from the group consisting of lungs, peripheral organs, blood vessels, arteries, veins, and blood fluid, and ii) in the case of plants, the selecting is from the group consisting of xylem, phloem, root, leaf and stem, C) preparing a description of one or more of the compartments in a computer program with regard to one or more transport processes selected from the group consisting of transport from and to the compartments, degradation processes, and active transport processes, and wherein the description comprises mass transport equations and kinetic reaction equations, D) describing the transport processes and/or the degradation processes of the administered active compound in the organism by mass transport equations and kinetic reaction equations, E) combining the equations in steps C) and D), to provide a numerical calculation of the resulting system of coupled differential equations, and F) determining the concentration-time curve of the active compound in the selected compartments.

Abstract
A method for determining the interaction of one or more chemical active compounds with organisms. The method comprises selecting at least one compound and analyzing its physiko-chemical and/or biochemical characteristics including its pharmacokinetic properties in various anatomical and physiological compartments of the organism in question. The relevant physiological compartments are characterized with respect to the compound'"'"'s various pharmacokinetic properties that may vary with the mode of administering the compound. A combined system of coupled differential equations is then used to simulate a concentration-time curve of the active compound in selected compartments.
