  In the present invention, the log P value is a coefficient indicating the affinity of an organic compound for water and 1-octanol. 1-octanol / water partition coefficient P is a distribution equilibrium when a trace amount of compound is dissolved as a solute in a two-liquid solvent of 1-octanol and water, and is a ratio of the equilibrium concentration of the compound in each solvent. It is common to show them in the form of their logarithm logP relative to the base 10. Log P values of many compounds have been reported, and many values are listed in databases available from Daylight Chemical Information Systems, Inc. (Daylight CIS), etc., and can be referred to. When there is no measured log P value, it can be calculated by a program “CLOGP” or the like available from Daylight CIS. This program outputs the value of “calculated logP (ClogP)” calculated by the fragment approach of Hansch, Leo together with the measured logP value, if any.

  The fragment approach is based on the chemical structure of the compound and takes into account the number of atoms and the type of chemical bond (cf. A. Leo, Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, PG Sammens, JB Taylor and CA Ramsden, Eds., P.295, Pergamon Press, 1990). This ClogP value can be used in place of the actual logP value in selecting a compound.
